On January 12, the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine jointly issued the “** Industrial Pollutant Discharge Standards†and “** Industrial Pollutant Discharge Standards†and formally implemented them on March 1. Both of these national standards were issued for the first time and set specific requirements for the limits, monitoring, and monitoring of wastewater and air pollutant emissions from industrial companies and industries.
The "Sulfuric Acid Industrial Pollutants Discharge Standard" strictly regulates the emission of sulfur dioxide, sulfuric acid mist, particulate matter and other atmospheric pollutants from sulfuric acid production enterprises (excluding smelting flue-gas acid-making and sulfuric acid-based acid production enterprises). The strict restriction on sulfur dioxide is The biggest challenge for the company. The "Standard" stipulates that for established sulfuric acid enterprises, the emission limit for the emission of oxidizing dioxide* is 860 mg/m3 from October 1, 2011 to September 30, 2013, as of October 1, 2013. The daily emission concentration limit is 400 mg/m3. The newly constructed company will implement a discharge concentration limit of 400 mg/m3 starting from March 1, 2011. Compared with the previous draft, the implementation date of the officially released standard has been delayed, which gives the company more time to make changes.
The “** Industrial Pollutant Emission Standard†requires existing enterprises to have a nitrogen oxide emission limit of 300 mg/m3 for atmospheric pollutants from April 1, 2013, and for new construction enterprises from March 1, 2011. The unit's baseline displacement is 3,400 cubic meters per ton. The "Standard" also specifies the specifications for ammonia nitrogen, total ammonia and total phosphorus in wastewater. Among them, the debut of the ammonia nitrogen and nitrogen oxide emission standards, and the "twelve five" countries to increase the two binding indicators coincide.
One of the main drafters of the two standards, Prof. Yang Bo of the Institute of Environmental Protection of Qingdao University of Science and Technology, told reporters that ** and ** industries are major emission sources in the chemical industry. Of these, only ** industry's annual emission of dioxide dioxide is about 100,000 tons, accounting for 9% of the chemical industry's emissions. China's ** industry has annual economic losses of 2 billion yuan due to the emission of carbon dioxide*. The new standard will force the regulation of enterprises' sewage discharge behavior, which is of great significance for promoting the progress of production processes and pollution control technologies. In addition, the two standards specify the special emission limits for water and air pollutants, providing a basis for future implementation of more stringent emission standards in some regions.
Qi Hao, Chairman of the China Industry Association, believes that in order to cope with the new standards, **companies should adopt measures such as improving the performance of catalysts and increasing exhaust gas absorption devices, while accelerating the research and development of high-quality domestically produced catalysts and replacing high towers with high-gravity equipment to improve The promotion of techniques such as the rate of absorption and ensuring that the indicators such as exhaust emissions meet the standards.
