Huang Youyu, director of the Pollution Control Department of the Jiangsu Provincial Environmental Protection Department, said that the total output value of the Jiangsu chemical industry ranks second in the country. At present, there are more than 30,000 chemical companies of various types in the province, producing a total of more than 20 gates and more than 30,000 items. Variety of chemical products. The survey shows that the annual discharge of wastewater from the Jiangsu chemical industry accounts for 30% of the total industrial wastewater discharge in the province. The major pollutants such as COD, ammonia nitrogen, volatile phenols, and petroleum emissions from the chemical industry accounted for 25%, 50%, 62%, and 33% of the total industrial wastewater emissions in the province, ranking the forefront of the industry and being listed as province-wide. "The first big sewage." Among the 20 key enterprises before the industrial wastewater discharge in Jiangsu Province, the chemical industry accounted for 15 companies.
The forthcoming "Jiangsu Provincial Chemical Industry Major Water Pollutant Emission Standards", based on the current situation of the province's environmental quality, has focused on increasing the "threshold" for the discharge of 7 key chemical companies to meet the standard, so as to encourage the polluting enterprises to actively meet the primary emission standards. Get closer. At the same time, according to the principle of promoting the adjustment of industrial structure, local standards put more stringent requirements on the major water pollution emissions of small and medium-sized chemical companies. The new emission standards are also based on the principle of “concentrated sewage controlâ€, which clearly defines the limits of water pollution discharge in industrial concentration areas and encourages the sewage generated by chemical companies to enter sewage treatment plants for centralized treatment. Obviously, the introduction of the new standard will promote the structural adjustment of the chemical industry in Jiangsu. A group of companies that consume high amounts of pollutants and are unable to do so will be merged or eliminated.
Jiangsu's chemical industry will adopt a higher discharge standard
The Jiangsu Provincial Bureau of Quality and Technical Supervision recently presided over the "Jiangsu Provincial Chemical Industry Major Water Pollutant Emission Standards" review meeting and officially passed the new local emission standards for the chemical industry in Jiangsu Province. The new chemical industry emission standards focus on three main pollutants, namely COD, ammonia nitrogen and total phosphorus, and specify the maximum allowable concentration of 25 water pollutants. After the prediction, after implementation of the new local standards, by 2010, the total discharge of COD, ammonia nitrogen, and total phosphorus from major chemical pollutants in Jiangsu Chemical Industry will be reduced by 25%, 24%, and 15%, respectively, compared with 2005.
