The relevant person in charge of the Ministry of Environmental Protection of China revealed on the 28th that China will implement the "Rare Earth Industrial Pollutant Emission Standards" from October 1, 2011 to solve the increasingly prominent environmental pollution problems in China's rare earth production process and improve the access of rare earth industries. Threshold, protection of rare earth strategic resources. According to reports, the "Rare Earth Industry Pollutant Emission Standard" is the first national pollutant discharge standard issued by the Ministry of Environmental Protection during the "Twelfth Five-Year Plan" period. This standard is applicable to the water and exhaust pollutant discharge management of various scale production processes and devices engaged in the production of rare earth mines 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. Statistics show that at present, China's rare earth reserves account for 36% of the world's total, and production accounts for 97% of the world's total. Due to over-exploitation, China's rare earth resource reserves have declined rapidly, and environmental pollution problems in the production of rare earths have become increasingly prominent. Taking ammonia nitrogen as an example, the annual output of waste water in the rare earth industry amounts to more than 20 million tons, of which the ammonia nitrogen content is 300~5000mg/L, which is more than ten times to hundreds of times higher than the national emission standard. Since there are no pollutant discharge standards for the characteristics of rare earth industry, the environmental impact assessment, design and completion acceptance of pollutant emission management and construction projects of rare earth industrial enterprises have long been able to implement comprehensive pollutant discharge standards and production processes of rare earth industries. The characteristic pollutants emitted in the medium have not been effectively controlled. According to reports, the "Rare Earth Industrial Pollutant Emission Standards" to be implemented will be based on the characteristics of the production process and production equipment of rare earth industrial enterprises and the composition of raw and auxiliary materials, and the main pollutants discharged from the production of rare earth industrial enterprises will be used as control items for the rare earth industry. Wastewater, exhaust gas and emission control of radioactive materials are clearly defined. In order to prevent enterprises from diluting emissions, the standard product base displacement and unit product base displacement are also specified in the standard. The above-mentioned person in charge said that after the implementation of the "Rare Earth Industrial Pollutant Emission Standards", the new enterprises of the rare earth industry must be strictly implemented according to standards. Existing companies will also implement the same emission limits after a two-year transition period.
