Coal mine waste water treatment and reuse technology Comparative Study Digest： Introduced the sewage and wastewater processing resources of the latest technologies and processes, analysis and comparison of the three kinds of process options to deal with coal mine waste water system investment and operating costs, and to explore the reverse osmosis water treatment technology in the coal mine waste water treatment application The technical and economic feasibility.Coal mine waste water treatment and reuse of the consolidated operating costs for the :2.185-2 .465 yuan / ton. One membrane of the processing costs as low as: 2.185 yuan / ton. Such prices on drought and water shortage in the Northwest region is very attractive. Of mine waste water recycling, not only can reduce the amount of wastewater discharge, but also can make water resource, it should be said, it is a method of water resources in the hope of regeneration, but also our country to achieve sustainable use of water resources in an effective way to . Key words: reverse osmosis electroplating wastewater recycling。 China's large population and uneven spatial and temporal distribution of freshwater resources, water resources and socio-economic development is not balanced; population growth has increased year after year the demand of water resources, industry's rapid development has become increasingly serious water pollution, thus creating a shortfall of water resources and water pollution are increasing.At present, China's prominent contradiction between water supply and demand, there are more than 300 cities short of water, of which there are 114 cities in serious water shortages. Water supply and demand in China in the 21st century the situation was very serious water crisis will become a question of resources in the most severe punishment of all issues. To resolve this problem, in addition to the scientific management of water resources and optimizing the assigned amount, the high-tech means to bring into full play the role of the use of water resources is also very crucial. In recent years, China's annual volume of about 400-500 million sewage M3, treated emissions from only 15-25%, due to cross-flow of sewage everywhere, so that all our major sources of water produce different degrees of pollution, a serious deterioration of water environment 【4】 .Therefore, to enhance wastewater treatment, so that not only the discharge standards but also to a large number of reuse, very necessary, which improve the water environment to ease the shortage of water resources, saving precious water resources are very important. Urban and industrial sewage has been the depth of treatment can be used for agricultural irrigation, industrial production, urban landscape, Urban Green, life miscellaneous, groundwater recharge, and additional surface water in such applications as 【8】 .Traditional water treatment technology can eliminate some air pollutants, the COD, BOD and heavy financial and other indicators of reduced pollutant emission standards, or
