Release of pollutant emission standard for rare earth industry

Environmental Protection Department issued the "Rare earth industry pollutant emission standards", the Environmental Protection Department issued the "Rare earth industry pollutant emission standards", since October 1, 2011 to implement.　　The Ministry of Environmental Protection said that this is the "Twelve-Five" period of the Ministry of Environmental Protection issued the first national pollutant emission standards, the formulation and implementation of standards will be conducive to increasing the entry threshold for rare earths industry, accelerate the transformation of the Rare-earth industry development mode, promote the restructuring of rare earth industry, promote the sustainable and healthy The director said that rare earths are non-renewable important strategic resources, in the national economy in various sectors of the application is increasingly widespread. After years of development, the scale of China's rare earth industry has been expanding, but there are still illegal mining, overcapacity, ecological environment damage and waste of resources in the development of rare earth industry, which has seriously affected the healthy development of the industry. Statistics show that at present, China's rare earth reserves accounted for 36% of the world, production accounted for 97%. Due to overexploitation, the rare earth resources in China have been declining rapidly, and the environmental pollution in the process of rare earth production is becoming more and more prominent. Taking ammonia as an example, the Rare-earth industry produces more than 20 million tonnes of wastewater a year, of which the ammonia nitrogen content is 300~5000mg/l, exceeding more than 10 times times the national emission standard.　　Due to the lack of pollutant emission standards for the rare earth industry, the environmental impact assessment, design and completion acceptance of pollutant emission management and construction projects in rare earth industrial enterprises have been carried out for a long time. In order to solve the problems existing in the rare earth industry, improve the technological level of mining, smelting and application, protect the national precious rare earth Strategic Resources, the Ministry of Environmental Protection has carried out the development of the emission standard of rare earth industry. According to the production process of rare earth industry enterprises, the characteristics of production equipment and the components of raw and auxiliary materials, the pollutant emission standard of rare earth industry has made clear regulations on the control of waste water, exhaust gas and radioactive materials in rare earth industry as a control project. In order to prevent enterprises from diluting emissions, the standard also stipulates the unit product base displacement and unit product base exhaust quantity.　　The standard applies to the management of water and exhaust emissions from the production processes and devices of various scale features of rare earth mining to Rare-earth metals and alloys in China, as well as the environmental impact assessment, design and completion acceptance of Rare-earth industrial construction projects. The official said "the rare earth industry pollutant discharge standard" After the implementation, the new enterprise must strictly according to the standard implementation, considering our country rare earth industry existing Enterprise's actual situation, the standard to the existing enterprise set up the two years standard discharge transition period, after the transition period, the existing enterprise also must execute the new enterprise emission limit value
