2008: Remediation Of Polluting Leather Enterprises To Promote Energy Conservation And Emission Reduction

Yulin, Guangxi, persists in taking energy conservation and emission reduction as an important means to pform the mode of economic development. It actively promotes the production mode of energy conservation and environmental protection, vigorously develops the circular economy, pays attention to increasing the work of energy conservation and emission reduction, and achieves gratifying achievements in energy conservation and emission reduction.

Adjusting the industrial structure and promoting structural emission reduction, Yulin insists on using the market mechanism, increasing the pressure, and supporting the superior and the inferior, as an effective measure to reduce energy consumption and reduce the discharge of major pollutants.

Since the implementation of this measure, the cement industry has achieved remarkable results and has effectively promoted the structural optimization and upgrading of the cement industry in the whole city.

According to statistics, by the beginning of August this year, a total of 13 cement enterprises were forced to turn into a shutdown state, reducing backward production capacity of about 850 thousand tons / year, and reducing sulfur dioxide emissions by 80 million 780 thousand tons.

After the completion of the two phase project of Xingye and Beiliu conch, the original 64 old technology enterprises with high energy consumption and high pollution and vertical kiln cement will face more severe technical pformation or elimination pressure. The cement industry structure in Yulin will achieve comprehensive optimization and upgrading.

At the same time, Yulin insists on using administrative, market and legal means to eliminate the high energy consumption and high polluting enterprises such as indigenous papermaking, iron and steel smelting, and to curb the upward trend of the emission of major pollutants from high polluting enterprises from the source.

Starting from January this year, the government started to shut down 83 soil paper factories in the upper reaches of the Qing Wan River, and implemented the rectification operations, closed down production and closed down, and concentrated on dredging the polluted river channels, and resumed the original production of the occupied farmland.

The results of environmental monitoring in November 2007 showed that good results were achieved in remediation.

The water quality of most monitoring points in the upper reaches of the Qing Wan river is up to class III water quality standard.

By shutting down 335 soil paper factories in the upper reaches of the Qing Wan River and Beiliu City in accordance with the law, the backward papermaking capacity that does not conform to the national industrial policy can be eliminated by 170 thousand tons / year, and the COD emissions will be reduced by 8478 tons.

In addition, Yulin also plans to close more than 600 other polluting soil paper shops in batches.

With technology as a support to promote engineering emission reduction, Yulin insists on supporting technology, increasing investment, accelerating construction of emission reduction projects, and reducing pollutant emissions.

For the 34 ceramic enterprises of Beiliu and Lu Chuan, it is required to achieve the discharge of pollutants within the prescribed time, and the enterprises that fail to complete the task of overdue treatment will stop production first, and the government will take measures to shut down the treatment if they fail to meet the standards.

For example, Beiliu took the Guangxi Sanhuan group as a pilot project to grasp the demonstration project of "coal to gas" and carry out the "tough battle of pforming black smoke from ceramics" and achieved outstanding results.

The city has mandatory installation of high voltage electrostatic smoke and dust removal equipment for coal-fired tunnel kiln, and encourages enterprises to pform coal fired kilns, using clean fuels such as natural gas, liquefied petroleum gas, or clean electric kiln.

By the end of July this year, 8 new electrostatic precipitators were installed in the ceramic tunnel kiln, 28 units were repaired and run, 10 of the tunnel kiln was converted from coal to gas, 83 of which had been treated by the catalytic oxygen filling plant, which greatly reduced the emission of sulfur dioxide and chemical oxygen demand.

Driven by Sanhuan group, finance and other companies have also accelerated the "coal to gas" project.

At the same time, Yulin has also accelerated the centralized sewage treatment project of garment washing enterprises, vigorously promoted the application of energy saving and environmental protection mature technology, and accelerated the reuse of waste gas, waste residue, waste water and various kinds of production and living waste and deep processing engineering construction.

For example, Guangxi Yue Jing pulp and Paper Co., Ltd. mainly built up a dripping and leak emergency system, and further improved the original alkali recovery and air flotation systems, and invested 12 million yuan in January this year to start the construction of the "oxidation ditch biological aeration treatment system". The biological bacteria treatment method was adopted to control the sewage, which was completed at the end of July and began to cultivate strains.

At present, it is applying to the autonomous region for acceptance. After operation, it will form a capacity of 20 thousand cubic meters of daily sewage treatment, which can reduce COD emissions by 3100 tons per year.

Yulin Fu Ying Leather Co., Ltd. invested 8 million yuan to build "oxidation pond aeration biochemical treatment" project, forming a daily processing capacity of 15 thousand tons of sewage, annual emission reduction of COD emissions of 3000 tons.

In October 2007, Lu Chuan County implemented the measures of "energy saving and emission reduction", resolutely eliminated backward production capacity, reduced emissions of sulfur dioxide and other pollutants, closed down 8 small and heavily polluted red brick factories and a backward steel plant with high energy consumption.

Determined to cut the environmental protection knife to the "small soil paper", the tradition of Yulin's soil paper production has a long history. Among them, the production of soil paper from Beiliu has a history of more than 400 years.

In recent years, due to the progress of paper technology and the demand of the market industry, the development of small soil paper has grown from small to large, and the number has gradually increased.

There are only 83 small paper factories in the Daliang River Valley in the upper reaches of the Qing Wan River, and 252 in the Beiliu City.

Because paper making is a highly polluting enterprise, small soil paper enterprises are mostly concentrated along the riverside of the Yangtze River, and a large amount of papermaking wastewater is directly discharged into rivers and rivers, causing serious environmental pollution.

"In 50s of last century, we washed rice water, washed vegetables in 70s, washed clothes in 80s, and made a detour in 90s."

The image of the local people's jingle reflects the malignant pformation process of the water body in the Qing Wan river.

According to local people's reflection, the water body of the Daliang section is dark red in the peak season of the production of small earth paper enterprises. It has become a truly "red water river" and "odour ditch" for more than six months.

The monitoring results of environmental protection departments showed that the water quality at the monitoring points exceeded the three types of water quality standards in the "surface water environmental quality standard". The most serious chemical oxygen demand in the river sections exceeded the standard by nearly 4 times, and the pollutants came from paper mill wastewater.

The Qing Wan river is the most important tributary of Yulin's mother river, the southern river basin, and it used to be the source of production and daily life for 3-5 people along the river.

Similarly, due to the distribution of 252 soil paper production enterprises on both sides of the river, the amount of sewage in the upper reaches of the Guijiang River exceeds 1 million 500 thousand square meters. The wastewater is strongly alkaline, pH value is over 10, and COD (chemical oxygen demand) is 800 mg / litre.

The pollution of the two rivers directly threatens the safety of drinking water sources of the masses, and even threatens the construction of the only "pollution-free vegetable production base" in the city.

"No doubt, small soil paper has contributed to the increase in employment and economic development of local farmers, but to date, this environmental economic account has not been paid."

As a vice mayor of Beiliu said, the city's fiscal revenue last year was more than 500 million yuan, more than 1000 people from 252 paper mills, 60 thousand tons of clay paper production capacity, about 40000000 yuan of annual output value, 10 million yuan of profits, and the tax revenue brought to the local government was only about 400000 yuan.

The small soil paper belongs to the "fifteen small" enterprises banned by the state. It has high energy consumption and low added value, and the pollutants discharged are much higher than the emission standards prescribed by the state.

With Yulin's efforts to build a famous city in Pan Beibu Gulf, the investment environment has been improving and attracting investment has been increasing. Many big projects and big construction are in favor of Yulin.

Yulin wants to seize the opportunity, readjust its industrial structure, change its growth mode, and vigorously develop five industrial clusters, such as machinery, cement, ceramics, health, clothing, leather and electronic information.

However, environmental capacity has become a bottleneck restricting future development.

According to the relevant regulations, during the "11th Five-Year" period, the emission reduction work of COD has become a binding index for economic and social development. The government of the autonomous region has also signed the responsibility for "11th Five-Year" pollutant reduction targets with the State Environmental Protection Administration. Yulin is the most heavily charged City in the total COD reduction in the region. Whether the emission reduction task can be completed is directly related to the future development of the city.

Deeds must be done and deeds will be fulfilled.

The closure operation is being implemented in a well planned deployment.

The municipal government unified leadership organization has carried out four stages of pollution remediation in the upper reaches of the Qing Wan river.

The first stage is called the centralized propaganda and deployment stage; the second stage is the self stop production and shutdown stage; the third stage is the joint enforcement stage; the fourth stage is the stage of leak detection and completion.

To this end, in the shutting down operation, the Yulin municipal government, on the one hand, strictly closed down the ban on small soil paper in accordance with the law. On the one hand, it actively conducted dredging work, took measures to arrange training for farmers, properly solved employment problems, guided owners to switch production, and developed alternative industries; at the same time, preferential policies were introduced to support the pfer enterprises.

The Yuzhou District government has adopted a tax exemption policy of "two minus three" for the production of paper mills, encouraged and supported the production of paper mills, and raised funds for labor and re employment from all levels to reemployment training for workers who closed the paper mill.

Beiliu invested in the construction of a large ceramic factory in Ping Zheng, and planned to recruit local paper mill workers. At the same time, experts from Guangxi University were invited to plan and design, adopt advanced pulping technology and waste water treatment technology, implement centralized production centralized management, and promote intensive and collectivization.

To strengthen supervision and inspection to achieve management and emission reduction in order to save energy and reduce emissions, Yulin must strictly adhere to the project EIA and adhere to the "four adherence" to the construction projects: stick to the principle of first evaluation and post construction; persist in taking the total reduction index as the precondition for the EIA approval of the construction projects, and establish a new project approval mechanism based on the total target volume; adhere to the "new old age", and increase the amount of pollutant discharge, and never allow breakthroughs in the total control index, and strive to increase production without increasing pollution or increasing production and reducing pollution; and adhere to the "four no approvals".

In the first half of this year, a total of 635 new projects were approved by the city. 617 items were rejected, 18 items of high energy consumption and high pollution which did not conform to environmental protection and national industrial policies.

In addition, we should strengthen the "three simultaneous" management and strictly check the acceptance of the project.

In the first half of the year, the city conducted 56 on-site inspections of the "simultaneous implementation" of the construction project, and 28 acceptance projects, so that the implementation rate of the new project "three simultaneous" reached 100%.

Relying on the special action to protect the health and environmental protection of the people, we should focus on the emission reduction work of the drainage enterprises in the concentrated drinking water source protection area in Yulin. The key river basins are the South Liu Jiang Reservoir to the big water pumping point, the six bridge to the Bobai water works pumping section, the Beiliu River, the North River Longsheng Town, the Xinfeng River Estuary to the Beiliu water pumping station, the Min River Bridge to the Rongcheng power station, and the industrial parks violating the environmental "three simultaneous" system, the urban entertainment establishments and the noise nuisance of the construction sites, etc., focusing on environmental law enforcement inspection, sending out 1000 law enforcement personnel, 1400 on-site sewage inspection enterprises, investigating 295 illegal enterprises, and 4 cases, and the penalty amount is 180 thousand yuan. At the same time, we should "punish illegal sewage enterprises".
