Shaoxing Keqiao Uses " 3 Cards " Forcing The Printing And Dyeing Enterprises In The Region To Reduce Emissions.

Before the big screen of the environmental remote monitoring room in Keqiao District, Shaoxing, the staff used the mouse to tap the interface, and the real-time operation of the whole area sewage enterprises was clear at a glance.

The monitoring time, instantaneous flow rate, the permitted discharge amount on that day and the actual discharge amount of the month are dynamically displayed.

Suddenly, in the upper right-hand corner of the big screen, two enterprises had a red card.

"This shows that their actual emissions have been used up in the month, and the sluice gates will be shut down automatically."

The voice of the operator has just dropped, and the mobile phone received by the leaders of the Environmental Protection Bureau and the head of the enterprise received a warning message that the actual emissions had reached 100% in that month.

This means that in the remaining 4 days of August, the two enterprises will be shut down and shut down.

This is a scene of promoting intelligence and environmental protection in Keqiao district.

"Taking real-time online monitoring to achieve credit card drainage, credit card exhaust, card printing mud, we can sit in the office to supervise corporate sewage."

District Environmental Protection Bureau Party Work Committee Deputy Secretary Yan Yulan said.

The "three cards" forced enterprises to reduce emissions, and the ecological environment in Keqiao district has changed significantly.

According to statistics, in the 1~7 month of this year, the water quality sections of class I and III increased from 13 to 18, and the grade IV water quality reduced from 5 to 1, and the compliance rate increased 8.7 percentage points. The excellent and good rate of air was 74.1%, up 6 percentage points over the same period last year, 760 thousand tons of standardized sludge disposal, 238 million kilowatts of sludge power generation, and the public satisfaction of the ecological environment quality was increased by 6.5 percentage points over the previous year.

Credit card drainage: "wisdom and environmental protection" breaking cocoon

Dyeing and weaving is the backbone of Keqiao.

。

According to statistics, in 2009, local printing and dyeing capacity accounted for more than half of the total capacity of the province and the whole country and 1/3. The annual industrial wastewater discharge amounted to 1.86 million tons, and the intensity of emission was 3 times that of the whole province.

Although after several years of regulation, a lot of excess capacity has been compressed, but there are more than 300 key polluting enterprises in Keqiao.

Faced with such a huge regulatory target, it is difficult to achieve effective supervision by relying solely on the strength of the environmental protection department.

In the era of Internet, how to use the resources under the line and strengthen the supervision of enterprise emission, Keqiao district has put forward a new idea of "intelligent environmental protection".

According to Ge Minmin, director of the eco technology development section of the District Environmental Protection Bureau, in February 2012, the Keqiao District Environmental Protection Bureau completed the first phase of the credit card drainage system.

The printing and dyeing enterprises store the approved drainage amount into the IC card every month, and can see in real time the information of the total amount of discharged sewage, the amount of discharge, the state of the valve and so on on the screen of the enterprise installation and the system platform of the environmental protection department.

When the drainage amount in the month reaches 80%, 90% and 100%, the automatic monitoring platform will display the current sewage discharge status in three different colors, blue, yellow and red.

At the same time, the system will automatically send SMS messages to the person in charge of the enterprise, the environmental protection administrator and the environmental protection department responsible person.

Once it reaches 100%, the red card will appear, and the drain valve will be shut down automatically by the system.

After the system was put into operation, the total amount of sewage discharged from the whole area was controlled from the highest 900 thousand tons / day to the current 540 thousand tons / day, and the Keqiao district has become the double pilot area of the automatic monitoring system for pollution sources and the automatic control system for the total discharge of the card.

After having tasted the sweetness of the credit card drainage system, the Environmental Protection Bureau of Keqiao district started the two phase project immediately. It was completed and operated in September 2012, and realized the full coverage of five industries, such as printing and dyeing, chemical industry, paper making, leather making and electroplating, so as to control both the total quantity and the concentration.

At present, Keqiao district has built 225 automatic control systems (including more than 250) of the total amount of credit card discharge.

In the 1~7 month of this year, the credit card drainage system was shut down 404 times, and the sewage discharge volume of printing and dyeing enterprises was reduced by 3 million 720 thousand tons.

Card exhaust: wear a respirator to the machine.

24 hours to boot, always alert.

This is a Binhai Industrial Area.

Environmental protection administrator, Bin Bin's daily work.

"The most worrying thing now is to hear the text message, because it may cause the enterprise to be punished, and will also be deducted from the bonus."

Where the shore is concerned, a set of "automatic monitoring system for exhaust emissions from stereotype machines" issued by District Environmental Protection Bureau is issued. Once the exhaust gas exceeds the standard, the system will alarm. If it is not handled in time, the enterprise will be deducted or even punished.

"Inspired by the card drain, we explored the river crossing the river by feeling the stones, and developed a set of" on-line automatic monitoring system for the exhaust emission of the stereotype machine "in cooperation with the scientific research units, which filled the gap in the field in China and passed the trial for more than a year to reduce the exhaust emission.

Yan Yulan said that in July last year, the District Environmental Protection Bureau chose Zhejiang Tong Yi textile printing and dyeing Co., Ltd. as the first pilot installation enterprise.

The company set up 17 sets of stereotypes machine exhaust treatment facilities installed 3 sets of automatic monitoring system to achieve full coverage of information chain, data link and processing equipment monitoring.

On the roof of the "Tong Yi textile" factory, the reporter saw that the exhaust gas treatment facilities of the 3 large sizing machines were running at high speed.

General manager Zhou Lifu told reporters that these equipment is like putting a "big mask" on the stereotype machine, the air in the workshop is good, the exhaust gas is also less, and the automatic monitoring system of the card exhaust can directly let the data speak.

At present, there are 183 printing and dyeing enterprises and 1762 stereotyping machines installed in the region.

When the automatic monitoring system for exhaust gas of each stereotype machine is running, the environmental protection department can monitor over the horizon, collect data 48 times in 24 hours, and update the online monitoring data every half hour.

So far, 4 enterprises have been punished by the environmental protection department for failing to open the processing device properly.

"Since the exhaust emission of enterprises has been put on the" big mask ", our surrounding residents feel less odour and the air is much better.

A resident living near the factory was pleased to tell reporters.

Credit card discharging mud: "production, supply and marketing"

As a large area of printing and dyeing industry, Keqiao produces 2000 tons of printing and dyeing sludge every day. Disposal of sludge has always been a difficult point in environmental supervision.

Keqiao district was inspired by the card drainage and exhaust, and created "

The supervision mode of sludge.

Last year, Keqiao's environmental regulation "credit card" family also had a rising star - credit card drain.

Since last May, Keqiao district has taken the lead in the implementation of the "six unified" sludge disposal method for 30 printing and dyeing enterprises, such as unified pportation, unified disposal and unified settlement. The printing and dyeing enterprises, the Longde environmental protection company, the Environmental Protection Bureau of Keqiao District, has been managed and controlled, and the "quasi industrial permit for industrial sludge in Keqiao" has been issued. The management and standardized disposal of all printing and dyeing sludge are carried out, so as to effectively prevent the two pollution of industrial sludge in printing and dyeing enterprises.

At present, the printing and dyeing enterprises that have established a cooperative relationship with industrial sludge in the Longde environmental protection thermoelectric Co., Ltd., the rate of "credit card drainage" has reached 100%.

With the goal of "credit card printing and on-line monitoring", the professional pportation company of sludge was determined to implement quantitative, fixed, fixed and fixed routes. All the sludge factories and vehicle pportation were carried out by credit card recording and GPS on-line automatic monitoring. The regulation of "production, supply and marketing" was implemented for sludge disposal in enterprises, effectively preventing the occurrence of illegal stealing and dumping of sludge.

"Environmental protection department's management of credit card discharge sludge is as strict as bank management credit card: first, the quota is defined, and the amount of sludge generated by each enterprise is determined. Two, after the bill is submitted, the environmental protection department can grasp the disposal of enterprise sludge in every time after the credit card is sent, and the three is the periodic settlement. The environmental protection personnel verify the enterprise according to the monthly credit card record, and the four is the credit record. If the enterprises find illegal activities, they will be included in the blacklist of environmental protection credit."

Ye Baigen, who has worked for 20 years in environmental protection work, told reporters about the function of card printing and sludge discharge.

Since the operation of the credit card drainage system, 32 enterprises have already issued written warnings to the 23 enterprises that do not regulate the printing and dyeing sludge. 23 enterprises have ordered the rectification to be made within a time limit. 14 enterprises have imposed administrative penalties.

Credit card drainage, credit card exhaust, card printing mud, Keqiao area with "wisdom and environmental protection" forced pformation and upgrading of enterprises, but also changed the view of many business operators.

Like "Tong Yi textile", it not only improves the added value of printing and dyeing fabrics through technological innovation, but also spends huge sums of money on introducing reverse osmosis water facilities to expand wastewater reuse.

In the words of general manager Zhou Lifu, "enterprises use tap water at 3.1 yuan per ton, and NNP drain at another 3.5 yuan per ton. Although the cost of using reverse osmosis technology to reuse wastewater is higher, the cost of using reverse osmosis water is calculated at the same time."

At present, sewage interception and emission reduction has become a conscious action of many enterprises in Keqiao. This change will inspire more people, and make unremitting efforts to protect green water and green hills and build a beautiful home of blue sky and green water.
