Four Major Environmental Storms Are About To Start! Please Prepare The Printing And Dyeing Industry Ahead Of Schedule!

The second round of central environmental protection inspectors, blue sky defense, clear water defense, pure land defense and other four major environmental storms are coming!

Some time ago, Minister of ecology and environment Li Ganjie clearly stressed that this year will start a new round of central environmental protection supervision work for a period of 4 years, and the relevant departments of the State Council and the central enterprises will be included in the scope of supervision.

These are all 100% fixed things. There is no suspense.

It is understood that the preparations for the second round of central environmental inspectors are in the process of preparation. The inspection team has initially determined that the relevant inspectors' scheduling is in progress.

It can be said that "everything is ready, only owing to the east wind". As long as the Central Committee orders, several inspectors will be dispatched in a thunderbolt.

According to the three year plan of action to win the blue sky, 2019 will be a crucial year.

After the Spring Festival, the work of defending the blue sky continues, and the Ministry of ecology and environment also has a clear planning path.

Specific aspects include: solid coal management steadily, implementation of diesel vehicle pollution control action plan, related industries to accelerate ultra-low emission pformation work, strengthen VOCs governance, key areas of autumn and winter pollution prevention and control continuation, and "scattered pollution" enterprise combat and governance.

A few days ago, the Ministry of ecology and environment announced that the environmental protection special operation of drinking water sources launched in 2018 has achieved remarkable results, and has completed 99.99% of the work tasks to ensure the safety of drinking water for 550 million people.

After the Spring Festival, the defense of blue water will further expand and deepen.

A number of tackling operations such as the Yangtze river restoration, black odor water treatment, Bohai governance and rural sewage treatment will be launched in batches. The environmental protection work of drinking water sources will also continue to advance, with a larger scope, more tougher measures and more severe punishment, so as to ensure that the battle of green water is really won.

The prevention and control of soil pollution was formally implemented in January 1, 2019.

After the Spring Festival, the implementation of this law will become the center of environmental protection work.

According to reliable sources, the matching rules for soil pollution prevention and control law will be introduced one after another, and the relevant governance actions will be launched nationwide.

After the Spring Festival, work has been done clearly: agricultural and rural land detailed investigation, industrial enterprise land survey, construction of soil pollution prevention and control pilot and demonstration.

The wastewater treatment facilities are not operating normally, including the discontinuation of the wastewater treatment facilities, the failure of a certain part of the wastewater treatment facilities, the over treatment process of wastewater, the maintenance of wastewater treatment facilities without the design requirements, and the daily capacity of the waste water to exceed the daily capacity of the wastewater treatment facilities.

Legal links: the thirty-ninth law of the prevention and control of water pollution in People's Republic of China: prohibit the use of seepage well, seepage pit, crack, karst cave, private underground pipe, tampering, forgery monitoring data, or abnormal operation of water pollution prevention measures and so on to prevent and control the discharge of water pollutants. According to the provisions of the first paragraph (three) of article eighty-third of the water pollution prevention law of the People's Republic of China, it is ordered to rectify or restrict production and production stoppage, and impose a fine of more than one hundred thousand yuan or one million yuan.

Due to the improper management of wastewater treatment facilities and the inability of wastewater treatment facilities to meet the current situation of enterprises, the effluent exceeded the standard discharge.

Legal links: the tenth discharge of water pollutants in the law of the People's Republic of China on the prevention and control of water pollution shall not exceed the national or local standards for the discharge of water pollutants and the total discharge amount of key water pollutants.

In accordance with the provisions of paragraph 1 (two) of the eighty-third article of the law on the prevention and control of water pollution in People's Republic of China, it shall be ordered to rectify or restrict production and production stoppage, and to impose a fine of more than one hundred thousand yuan or one hundred yuan. It is a fine; if the circumstances are serious, it shall be reported to the people's government having the power of approval, and shall be ordered to suspend business or close down.

Nowadays, the environmental awareness of enterprises is relatively high, and there are few pollutants discharged through rainwater outlets. However, because of the problems of management, land subsidence, pressure piping, pipeline blockage, rain and pollution mixing, the phenomenon of pollutant discharge from the rainwater outlet often occurs.

The operation and maintenance account of wastewater treatment facilities includes: the running time, dosing records and maintenance records of wastewater treatment facilities. The ledgers are records of environmental protection facilities management by enterprises, and enterprises should be responsible for the authenticity and integrity of accounts.

It is particularly urgent to note that the illegal operation of "abnormal operation of pollution prevention facilities" is subject to administrative detention.

We can refer to the Interim Measures for administrative departments to pfer cases applicable to administrative detention for environmental violations.

The provisions of the sixty-third provisions and third provisions of the environmental protection act are not running properly, such as the prevention and control of pollution facilities, and so on.

(1) direct discharge of some or all of the pollutants without treatment facilities;

(two) emergency discharge valves to open pollutants handling facilities in non emergency situations to directly discharge part or all of the pollutants.

(three) direct disposal of untreated pollutants from intermediate processes of pollutant treatment facilities.

(four) in the course of production, operation or operation, the pollutant disposal facilities shall be stopped.

(five) the use of pollutant treatment facilities in violation of operational regulations will result in the disposal facilities being unable to function properly.

(six) after the failure of the pollutant treatment facility, the pollutant discharge unit is not in time or fails to carry out inspection and maintenance according to the regulations, resulting in the disposal facilities can not play the role of normal disposal.

(seven) other abnormal operation of pollution prevention and control facilities.

Unorganized emissions of exhaust gases

All of these behaviors are emissions from exhaust gases.

For example, the dust and waste gas generated by cutting, welding and other links in the machining industry.

Most of the production and service activities of producing waste gases containing volatile organic compounds should be carried out in confined space or equipment, and installation and use of pollution control facilities according to regulations.

Note that the vast majority of Oh!

For example, the delivery ports of volatile organic compounds such as acetone, toluene, xylene, dichloromethane, aromatic amines, and filling ports containing such substances must also be carried out in confined space or equipment.

Most of the production and service activities of producing waste gases containing volatile organic compounds should be carried out in confined space or equipment, and installation and use of pollution control facilities according to regulations.

With regard to confined space, the environmental protection department has found many business owners' problems about "ventilation" in the process of law enforcement.

(1) air vent should be set up.

Because the function of the vent is to ventilate, it is to ensure that the exhaust gas in the production area is not aggregated to a certain concentration, resulting in chemical or other safety problems.

(2) the opening of the vent should be optimized instead of being arranged on top of the roof.

The vent should be a new air inlet. When setting, it should be optimized through indoor air and the proportion of the gas to be considered. For example, ventilation with air heavier than air, the vent should be installed on the roof, the return air outlet (exhaust collection treatment port) is installed at the bottom of the side wall, ventilation with lighter air than gas, vent and return port (exhaust gas collection treatment port) should be reversed facilities; and the vent setting for the relatively responsible exhaust gas should be checked by the relevant qualification department.

Excessive discharge of air pollutants

This is easier to understand. As the name suggests, exceeding the standard means that the air pollutants discharged exceed the national or local standards.

There are many standards. Here are not enumerated, some are executive standards, others are national standards, and some are local standards.

Here is a basic principle of judgement: strict enforcement of standards.

Emission of air pollutants by evasion of regulation

The most common behavior of escaping from the regulation of air pollutants is:

(1) in the daily production process, the exhaust treatment facilities are deliberately closed, resulting in direct exhaust emissions.

(2) the waste gas treatment facilities are good, that is to say, they can run the exhaust gas treatment effect, but they are not opened.

When the inspectors arrived, the waste gas treatment facilities were opened.

(3) the operation of the waste gas treatment facilities is not normal. If the additive is not added, the operation of the waste gas treatment facilities will not be inspected for a long time, resulting in the waste treatment facilities can not meet the requirements.

For example, the pH of the alkaline spray liquid should be 9 and above, but pH was neutral when examined.

(4) setting up a bypass facility for exhaust emissions.

What is bypass facilities?

It is to put another pipe on the exhaust pipe, which is bypassed the waste gas treatment facilities.

The explanation usually given by business owners is that, considering contingency.

This type of emergency is mainly concerned with the deterioration of waste gas treatment facilities.

From the point of view of environmental protection, considering the emergency situation, it is necessary to acquire the necessary emergency equipment instead of straight row.

(5) forged operation records of waste gas treatment facilities.

Failing to set up the outfall of air pollutants according to regulations

For example, the height of the exhaust cylinder is not enough; no monitoring holes, sampling platforms and emission signs are set up.

Ten important points: do well in environmental supervision.

In recent years, the protection of the ecological environment has been paid much attention. Especially in the area of pollution control, the government has always been very strict with all enterprises, especially the polluters. How can we avoid the "sword" of environmental protection supervision?

We are not afraid to do the following.

I. implementing environmental policies

1. in line with the national industrial policy and local industry access conditions, and meet the relevant requirements of eliminating backward production capacity.

2., strict implementation of the environmental impact assessment system and the "three simultaneous" system.

3. handle pollutant discharge permits according to law and discharge pollutants according to the permitted contents.

Two, upgrading equipment level

1. enterprises should adopt closed production process instead of open production process, preferentially adopt continuous and automatic production process instead of batch production process, and minimize the frequency of material contact with the outside world.

2. adopt advanced conveyor equipment.

The material pump, such as canned pump, diaphragm pump, magnetic pump and so on, is used to replace the existing water jet vacuum pump to convey liquid material.

Due to special reasons, compressed air and vacuum suction are used to pport flammable, poisonous and harmful chemical materials.

Priority should be given to vacuum equipment such as roots vacuum pump, oil free reciprocating vacuum pump and so on.

If the technology needs to adopt the jet vacuum pump or the water ring vacuum pump, the reactor tank or the tank type closed vacuum pump should be adopted, and the circulating liquid is equipped with the cooling system.

3. optimize the import and export mode.

The reactor should be fed at the bottom or immersed in the tube. The top part of the liquid should be adhered to the wall by the pipe, and the sealing device or the closed area should be installed for feeding and discharging.

4. improve the efficiency of condensation recovery.

In the distillation process, the multi stage gradient condensation method should be adopted to improve the recovery efficiency of organic solvents, and priority should be given to high efficiency heat exchangers such as spiral wound tubes or plate condensers.

5. adopt advanced centrifuge and pressure filtration equipment.

In addition to special process requirements, enterprises should replace the open centrifuge with closed centrifuges, multifunctional integrated filter press and undercurrent plate and frame filter press.

6. adopt advanced drying equipment.

Enterprises should adopt closed drying equipment or flash dryer, spray dryer and other advanced drying equipment.

The volatile solvents generated during the drying process need to be condensed and recycled and then connected to the exhaust gas treatment system. The presence of odor pollution should be effectively controlled.

7. standardize the storage of liquid materials.

Chemicals (including oil) storage tanks shall be equipped with recovery system or waste gas collection and treatment system.

Vent gas in the loading and unloading process of volatile acids and lye tanks must be absorbed by falling film or packing tower.

8. the implementation of the water-saving production process.

In addition to special technical requirements, the washing of materials is preferred by reverse flow rinsing process to encourage the use of sewage cascade.

Three. The production environment of the factory

1. according to the actual situation, the production workshop floor shall take corresponding measures of seepage prevention, leakage prevention and anticorrosion, and the workshop shall carry out dry and wet separation. The plant area must fully implement the "two pformation", that is, the hardening of the road site and the greening of other areas.

2. there is no leakage in the production site. The environment is clean and orderly.

The surface of the 3. tank farm and the general waste collection site should be hardened and impervious, surrounded by cofferdams, and the general waste collection sites should also adopt rainproof measures.

4. all kinds of pipelines in the plant area are clear, and the piping layout should be installed in a clear way, and will be lined up or lined up along the walls or columns.

Four. Waste water management

1., rain and sewage diversion.

The initial rainwater collection tank specification meets the volume requirements of initial rainfall; the workshop generated by waste water sets up the waste collection pool separately, and the collected sewage is then pumped into the total collection pool of the enterprise through the airtight pipe laid by the overhead pump; the cooling water is circulate through the airtight pipeline laid by the overhead installation; the rainwater collection system adopts the open ditch.

All trenches and pools are concreting, with anti-seepage or anticorrosive measures.

2. disposal of production wastewater and initial rainwater.

Wastewater treatment and discharge enterprises should set up wastewater treatment facilities matching production capacity and pollutant types. The normal operation of wastewater treatment facilities can achieve stable discharge. The enterprises that take over the waste water should establish a pretreatment facilities that are compatible with the production capacity and pollutant types, and the normal operation of the pretreatment facilities can stabilize the takeover standards; the enterprises entrusted with the disposal of wastewater must sign an agreement with qualified units, complete the examination and approval procedures and pfer procedures, and establish a entrusted disposal account.

3. disposal of domestic sewage.

The enterprises that have the conditions of taking over the domestic sewage must be taken over into the sewage treatment plant.

4. discharge port settings.

Each enterprise is allowed to set up a sewage outfall and a rainwater discharge port in principle, and set up sampling monitoring wells and signs.

The sewage outfall must conform to the requirements of standardized treatment, so as to achieve "one obvious, two reasonable and three convenient", that is, the environmental protection signs are obvious, the sewage outlets are set up reasonably, the sewage discharge direction is reasonable, and it is convenient to collect samples, facilitate monitoring and measurement, facilitate public participation and supervision and management.

Rainwater outlets should be constructed with regular trench and emergency valves.

Five. Exhaust gas management

(1) collection and pportation of waste gas

1. exhaust gas collection shall follow the principle of "receivable collection and quality collection".

The exhaust gas collection system should be designed according to the gas properties and flow rate to ensure the exhaust gas collection effect.

2. the equipment for producing scattered dust or harmful gas should be closed, isolated and operated under negative pressure.

3. the pollution gas should be collected as far as possible by the gathering system of the production equipment itself. The scattered gas should be surrounded or near the source of pollution when collecting the gas (dust) hood, so as to reduce the scope of inhalation and facilitate the capture and control of pollutants.

4. waste collection system and treatment facility unit (original tank, regulating tank, anaerobic tank, aeration tank, sludge room, etc.) should be collected in a closed manner and effective measures should be taken to deal with the discharge.

5. the solid waste (hazardous waste) storage area with volatile organic materials or odor is closed and the exhaust gas is discharged after collection and treatment.

6. the pollution gas collected from the collector (dust) hood should be pported to the purification plant through the pipeline.

Piping layout should be combined with production technology to make it simple, compact, short pipeline and less space occupation.

(two) waste gas treatment

1. the production enterprises should make comprehensive analysis based on the amount of exhaust gas, composition and nature of pollutants, temperature, pressure and other factors, and select mature and reliable exhaust gas treatment process.

2. for high concentration organic waste gas, condensate (cryogenic) recovery technology and pressure swing adsorption recovery technology should be used first to recycle organic compounds in waste gas, and then assist other treatment technologies to achieve discharge.

3. for medium concentration organic waste gas, adsorption technology should be adopted to recover organic solvents or thermal incineration technology for purification.

4. for low concentration organic waste gas, adsorption technology should be adopted when recovering value. When no recovery value is found, it is advisable to adopt adsorption concentration combustion technology, regenerative thermal incineration technology, biological purification technology or plasma technology.

5. odor gas can be purified by microbial purification technology, low temperature plasma technology, adsorption or absorption technology, thermal incineration technology and so on.

6. continuous production of chemical enterprises in principle should deal with combustible organic waste gas recycling or incineration treatment, batch production of chemical enterprises should be treated by incineration, adsorption or combined process.

7. dust exhaust should be treated by bag filter, electrostatic precipitator or bag filter.

Industrial boiler and industrial furnace waste gas priority to clean energy and efficient purification process, and meet the emission reduction requirements of major pollutants.

8. improve the automation of waste gas treatment.

The spray treatment facilities can be equipped with liquid level automatic control device, pH automatic control device and ORP automatic control device. The dosing tank is equipped with liquid level alarm device, and the dosing method is suitable for automatic dosing.

9. the height of the exhaust cylinder should be set according to the specifications, and the height of the exhaust pipe should be no less than 15. The height of the hydrogen cyanide, chlorine and phosgene exhausting tube is not less than 25 meters.

The inlet and outlet of terminal treatment shall be equipped with sampling ports and equipped with facilities for sampling.

We should strictly control the number of exhaust cylinders, and the same kind of exhaust gas cylinders should be combined.

Six. Noise management

As far as possible, enterprises should choose equipment with low vibration and low noise, and noise emission must comply with the requirements of industrial enterprises' environmental noise emission standards for factory boundaries (GB 12348-2008).

Seven. Solid waste management

1. hazardous wastes are classified and stored according to their characteristics.

2. hazardous waste storage sites have to be hardened to the ground, rainproof, anti disperse and anti leakage measures. Leachate passes through the diversion channel into the collection tank.

3. hazardous waste warning sites should be set up in hazardous waste storage sites, and hazardous wastes should be clearly marked on dangerous containers and bags.

4. establish a hazardous waste management account.

Truthfully record the relevant situation of hazardous waste storage, utilization and disposal, formulate a plan for hazardous waste management, report to the Environmental Protection Bureau for archival filing, declare and register hazardous waste, and truthfully declare relevant data of hazardous waste types, production volume, flow direction, storage and disposal.

5. hazardous waste should be entrusted to the units with corresponding qualification of hazardous waste disposal, and strictly implement the system of examination and approval of hazardous waste pfer plan and pfer system.

Eight. Cleaner production

The production enterprises need to complete the cleaner production audit on time according to the annual requirements, so as to meet the requirements of cleaner production standards in the industry.

Nine, environmental emergency management

1. establish and improve emergency management system.

The establishment of environmental emergency management institutions, the establishment of an environmental emergency management system, the implementation of environmental emergency management personnel.

2. to prepare contingency plans for emergencies in enterprises.

Commissioned by the professional and technical service institutions to prepare plans, and completed the internal assessment and external assessment on the basis of the times and environmental protection department prepared

3. large and above environmental risk enterprises should carry out environmental safety standards construction.

4. implement environmental risk prevention measures.

We should standardize the construction of environmental risk prevention facilities, including emergency response pools, initial rainwater collection tanks, production waste water shut off gate valves, storm drain outlets closing valves and dangerous chemicals storage tanks cofferdam and other emergency facilities, so as to ensure that once production safety incidents occur, production wastewater, fire water and so on will not be out of factory area, and will not pollute the external environment.

5. set up environmental emergency supplies storehouse.

The emergency materials and equipment in the contingency plan must be provided in place, and special warehouses should be set up.

6. regular staff training drills.

Organize an environmental emergency knowledge training and emergency environmental emergency exercise at least once a year.

Ten, standardize environmental management

1. standardize the construction of the whole process of the standardized facilities, and mark the symbols of the key nodes of the management facilities, map and so on, so as to make the whole process of the treatment facilities clear at a glance and realize the quantitative management of the facilities.

2. enterprises shall not demolish, idle or close the pollution prevention and control facilities without authorization, and ensure the stable operation of the pollution prevention and control facilities and the discharge of standards.

When the waste gas treatment facilities are stopped running due to accident status or equipment maintenance, enterprises should immediately take emergency measures and stop production in time, and report to the Environmental Protection Bureau.

3. complete environmental regulations, set up specialized internal environmental protection agencies, and establish corporate environmental management responsibility system composed of enterprise leaders, environmental management departments, workshop heads and full-time environment-friendly personnel.

4. the relevant archives are complete. Daily operation of waste water and waste gas treatment facilities, dosing, electricity consumption and maintenance records, and pollutant monitoring accounts are standardized.
