The draft of the "Pollutant Fertilizer Industry Water Pollutant Emission Standard" formulated by the Ministry of Environmental Protection has recently been completed. The relevant personnel of the Ministry of Environmental Protection Science and Technology Standards Division disclosed that relevant units are working on the improvement of the Opinion Draft, and will feedback before April 30th. Ministry of Environmental Protection Technology Standards Division, the official standard is expected to be implemented in January 2009. The new standard has adjusted the pollutant discharge control items and increased the control requirements for pollutant discharge; it has eliminated the regulations for the grading control according to the direction of the sewage; it no longer stipulates the pollutant discharge limit according to the size of the enterprise; it stipulates the special water pollutants. Emission limit.
The old standard is outdated. The current “Phosphorus Fertilizer Industry Water Pollutant Emission Standard†was issued in 1995. It is an implementation of the discharge standard according to the surface water environmental quality standards, and the discharge volume is determined according to the regional water resources conditions, which is not conducive to the improvement of environmental quality and fair competition. Secondly, in the current standard, the scale of phosphate fertilizer companies is divided into three types according to large, medium and small scales. According to the “Eleventh Five-Year Planâ€, the development of the phosphate fertilizer industry is mainly large-scale. In recent years, the phosphate fertilizer industry, especially ammonium phosphate, has developed rapidly, and the current standards There is a limited role in promoting the sustainable development of the industry, promoting energy-saving emission reduction, and encouraging technological progress; once again, the standard can not be adapted to the current requirements according to the time segment, and the phosphate fertilizer industry develops product structure and technology in the development of more than 10 years after the standard was promulgated. The economic capacity has undergone tremendous changes and the direction of future development has also been very different. The old standard has been unable to effectively control the future of the phosphate fertilizer industry's water pollution emissions; in addition, the current standard value is based on the production process of different product companies at that time. , sewage treatment technology and domestic sewage and treatment status definite. In the 1990s, the primary calcium and calcium magnesium phosphate fertilizers were the main varieties of phosphate fertilizer. The average size of the production enterprises was small, the technology was backward, and the pollution was serious. At present, the proportion of calcium and calcium magnesium phosphate fertilizer production has dropped by 90% at that time. To 40%. The “11th Five-Year†Phosphate Fertilizer Industry is developing in the direction of compound fertilizers such as ammonium phosphate, and the development of heavy calcium and nitrophosphates will not take place at the same time; at the same time, due to the increase in output and variety of compound fertilizers, it is necessary to increase the discharge control of compound fertilizers. The scope of application needs to be expanded.
The new standard has been issued with “callsâ€. In recent years, with the rapid development of the phosphate fertilizer industry, the discharge of water pollutants has also increased year by year. According to relevant experts, the amount of sewage discharged by the phosphate fertilizer industry in 2007 was approximately 5 million tons. The waste water discharged by the phosphate fertilizer industry is acidic wastewater. Its characteristic pollutants are fluoride and total phosphorus, which are harmful to water bodies. Among them, total phosphorus is the main indicator of eutrophication of the water body. Therefore, it is very important to control the discharge of water pollutants in the phosphate fertilizer industry. . According to the characteristics of sewage discharge from phosphate fertilizer industry, the pollution control project for the new standard is defined as COD, pH, suspended solids, fluoride, total phosphorus, total nitrogen, and ammonia nitrogen, among which COD, total nitrogen, and ammonia nitrogen are newly added indicators. It is to control the discharge of ammonia nitrogen in compound fertilizer production and prevent eutrophication of water bodies. In order to control the total amount of pollutants discharged and prevent the dilution of emissions, the new standard also sets the reference product's displacement as the control index.
According to relevant personnel of the Department of Science and Technology Standards of the Ministry of Environmental Protection, the new standard's fluoride limit is more stringent than the relevant US standards. The new company's standards are close to those of Japan, India, and Hong Kong; the total phosphorus limit is stricter than that of the US's phosphate fertilizer industry. The drainage limits of newly-built enterprises are basically the same as those of Hong Kong and Japan; the special emission limits of newly-built enterprises are in line with the drainage standards of Japanese Penghu, and they are stricter than the national standards of the EU and Germany. In recent years, China's phosphate fertilizer production has increased at a rate of 6.3%, and is expected to reach 16.42 million tons in 2011. After the implementation of the new standard, the total amount of wastewater discharged will be effectively controlled, in which the annual emission of fluoride will be reduced from 103.83t to 32.8t, and the annual emission of total phosphorus will be reduced from 121.2t to 32.8t, with a decrease of 68.4% and 72.9%, respectively.
"There are two types of fluoride emissions, liquid and gas emissions. Under the old standard, small companies have lower standards for gas phase fluoride emissions compared with large enterprises. The improvement of standards, in particular, no longer stipulates the discharge value of pollutants according to the size of the company, will It will promote the innovation and upgrading of large enterprises and will become an effective means of eliminating the pollution of small companies." A technician from Yuntianhua told reporters. Today, with increasing emphasis on environmental protection, it is important to implement energy conservation and emission reductions to reduce emissions of “three wastesâ€. However, prevention of pollution at the source is more important than pollution control, and the results achieved are even greater.
Not only is the new threshold for standards increased, but it has also increased monitoring and monitoring. Newly built enterprises shall install automatic pollutant discharge monitoring equipment in accordance with the "Measures for the Automatic Monitoring and Control of Pollution Sources" and link them with the monitoring equipment of the environmental protection department. The sampling of waste water discharged by the enterprise shall be carried out at the specified pollutant discharge monitoring location according to the type of pollutants monitored. A permanent discharge port sign must be set at the pollutant discharge monitoring location. Such detailed and stringent rules make companies “want to be hard to polluteâ€.
At the “Two Conferences†concluded recently, the government’s work report pointed out that it is necessary to improve the energy and resource conservation and environmental protection rewards and penalties mechanism, implement a statistical monitoring system for energy conservation and emission reduction, improve the auditing and monitoring system, strengthen law enforcement, and strengthen the responsibility for energy saving and emission reduction. system. In 2008, it was the most critical year for the “11th Five-Year Planâ€. The policies and regulations under the major pollution industry subdivisions were frequently introduced, conveying the government’s determination and confidence in achieving energy-saving emission reduction targets. As one of the polluting industries, the phosphate fertilizer industry faces challenges and opportunities for accelerated upgrading. Raising the barriers to pollution and encouraging new technologies to promote cleaner production will all effectively improve the industry's ability to resist risks and international competitiveness.
