Coal mine waste water treatment and reuse technology Comparative StudyDigest：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 mine waste water treatment and reuse of the consolidated operating costs for the : .465 yuan / ton. One membrane of the processing costs as low as: 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 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 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 miscellaneous safety standards, but can not completely eliminate the drainage contained in the solubility of trace contaminants. Reverse osmosis membrane technology to thoroughly remove these pollutants to achieve the strict sense of the wastewater reclamation. Traditional treatment processes and membrane technology integration can be sewage or waste water into a different water quality standards for reuse water, or make it loop back to use, this would ease the contradiction between supply and demand, but also reduce pollution, but also promote the development of environmental protection industry 【6】.Sewage Wastewater Reuse Technology and Application OverviewThe serious deterioration of water environment quality and the rapid economic development, and urgently requires a corresponding resource of sewage waste water technology. In this field of membrane separation technology occupies an important position and role. Membrane separation, as a high-tech in the last 40 years to develop quickly into the industrialization of the process of energy-efficient separation 40 years, electrodialysis, reverse osmosis, microfiltration, ultrafiltration, nanofiltration, pervaporation, membrane contact and membrane reactions have been developed in energy, electronics, petrochemicals, pharmaceuticals, chemicals, light industry, food and beverage industry and the daily life and environmental protection Dengjun wide range of applications received, resulting in significant economic and social benefits. The needs of the community to make membrane technology promised born, but also the needs of society to promote the rapid development of membrane technology to membrane technology innovation, technological progress, improve, and become a unit operation, to become integrated in the process of the key 【9】. membrane filtration technologyHollow fiber membrane due to large surface area membrane modules of the loading density, so compact equipment; this film made by spinning, simple process, so production costs are generally lower than the other films: In the absence of support layer may reverse cleaning, exceptional stain resistance of some good cleaning agent on the oxidative tolerance to the emergence of a good film made in large-scale sewage treatment works, the application of hollow fiber membrane has a unique advantage 【7】.CMF technology is the core of the high anti-pollution film, as well as compatible with membrane cleaning technology, which enables non-stop cleaning membrane cleaning, and thus to achieve a continuous treatment of liquid non-stop to ensure a continuous and efficient operation of is currently mainly used in large-scale municipal wastewater treatment plant raw water the depth of the secondary settling tank treatment and reuse, desalination, or large-scale reverse osmosis pretreatment system. Surface water ground water purification, beverages, etc. to clarify the bio-reactorMembrane bio-reactor is membrane separation technology and bio-technology combined with new technology. Used in the field of sewage waste water treatment using membrane pieces for solid-liquid separation, sludge or impurities interception return to the bio-reactor, handling the drainage of water through the membrane to form a sewage treatment membrane bioreactor system, The role of membrane modules is equivalent to conventional biological wastewater treatment systems in the secondary sedimentation tank 【4】.MBR used in the film are flat membrane, tubular membrane and hollow fiber membrane, is currently mainly based hollow fiber MBR wastewater treatment, raw water sources have reached a very high water guidelines. This method is not limited to domestic wastewater treatment, MBR technology is also widely used in dyeing wastewater, scouring wastewater, meat processing, sewage water treatment systems. Another feature of MBR systems vary in size, the small device can be used for a family, large-scale installations daily processing capacity of up to tens of thousands of cubic Osmosis TechnologyReverse osmosis technology is the early 20th century, 60 developed a pressure-driven membrane separation technology. The technology is from seawater, brackish water desalination and developed, often referred to as "desalination technology." As the reverse osmosis technology has no phase change, component-based, process simple and convenient operation, accounting for small size, less investment, low energy consumption advantages to develop very rapidly. RO technology has been widely used in sea water, brackish water desalination, pure water, ultra-pure water preparation, chemical separation, concentration, purification, waste water resource and other fields. Projects throughout the electric power, electronics, chemicals, light industry, coal, environmental protection, medicine, food and other resource is incremental development of freshwater resources and the protection of the environment a dual purpose. Inorganic series of wastewater treatment and seawater desalination of brackish water using the same equipment and have the more common process technology. RO can waste in copper, lead, mercury, nickel, antimony, beryllium, arsenic, chromium, selenium, ammonium, zinc ion removal addition to 90-99%.At present, the reverse osmosis technology in urban wastewater treatment, a number of industrial waste water treatment application of the depth has been a high degree of attention, including water reuse, wastewater treatment plant secondary effluent from the depth of treatment, after primary treatment of industrial waste water depth of processing system to take high-quality fresh water. Many water-scarce countries in the Middle East, in the extensive use of reverse osmosis desalination technology, the introduction of reverse osmosis technology technical processing secondary effluent, effluent quality up to TDS ≤ 80mg / L, the expansion of freshwater resources. Such as the Middle East, Australia, Singapore and other countries are examples of major projects in this area 【9】. membrane process wastewater treatment methodsIntegrated membrane process is ultrafiltration / microfiltration and reverse osmosis used in combination to form to meet the purpose of咱reuse wastewater treatment , microfiltration can be used as stand-alone high-level tertiary treatment method, is also an ideal pre-treatment process of reverse osmosis technology, anti-pollution ability, superior performance of ultrafiltration, microfiltration unit to replace the complex conventional treatment, and the water quality much higher than the three water indicators, not only can remove the sewage bacteria and suspended solids, the COD, BOD also have some effect but ultrafiltration, microfiltration after the use of reverse osmosis membranes, its traditional pre-wash cycle from 3-4 weeks to process more than six months, the membrane can prolong life for years to reach -6. Membrane integrated wastewater reclamation process has the system is stable, maintaining a small area of small, less use of chemicals, processes and operation of a simple and low Membrane Wastewater Treatment and Reuse of coal mine is technically entirely reliable, which has a successful the rapid development of industry, water pollution, worsening water scarcity will become increasingly serious, industrial wastewater recycling will be referred to the the environmental perspective, recycling of waste water re-use of mine has a very important environmental 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 .Of membrane processes for coal mine wastewater and reuse, both technically and economically feasible, economic and environmental benefits are very Shao.
