Jiangsu Province is a large chemical province. Last year, the sales revenue of petroleum and chemical industry products reached 394.914 billion yuan, ranking second in the country. The industry's annual profit reached 19.55 billion yuan, ranking seventh in the country. The province has a total of more than 30,000 chemical companies of all types, producing a total of more than 20 chemical products with more than 30,000 varieties of gates. However, the accompanying environmental pollution is also increasing. The survey shows that the annual discharge of wastewater from the chemical industry in Jiangsu Province has reached 775 million tons, accounting 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.
In order to improve the current state of high pollution in the chemical industry, Jiangsu started to compile the "Emission Standards for Major Water Pollutants in the Chemical Industry of Jiangsu Province", and determined inorganic chemical raw materials, organic chemical raw materials, petrochemicals, and chemical fertilizers in accordance with local standards and principles that are stricter to national standards. The allowable concentration of pesticides, macromolecule polymers, fine chemicals, and other seven categories and 25 types of water pollutants are controlled. It is understood that the focus of control is on COD, ammonia nitrogen, and total phosphorus in the discharge of pollutants. The discharge standard is 20% higher than the current national "Comprehensive Emission Standard for Wastewater." 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 meet the emission targets will be merged or eliminated.
It is reported that after the implementation of the new local standards, by 2010, the province's total chemical COD, ammonia nitrogen, and total phosphorus emissions will be reduced by 25%, 24%, and 15%, respectively, compared to 2005, ensuring that Jiangsu Province’s “11 V. The realization of the goal of reducing the total amount of pollutants by 15%.
Chemical province reshapes the image of environmental protection province Jiangsu chemical industry discharges new standard higher than national standard
The reporter learned from the relevant departments of Jiangsu Province on June 7 that the Jiangsu Provincial Bureau of Quality and Technical Supervision formally passed the "Jiangsu Provincial Chemical Industry Major Water Pollutant Emission Standards" on the "6th Five-Year" Environment Day. This marks the imminent implementation of the standard in the province. This standard focuses on three major pollutants including COD (Chemical Oxygen Demand), ammonia nitrogen, and total phosphorus. Among them, the emission standards of 25 kinds of water pollutants have been increased by 20% compared with the current National Integrated Wastewater Discharge Standard.
