Shortage of freshwater resources, while restricting China's economic development

, a large number of untreated Sewage Emissions Environment Also presented a great challenge. Water treatment technology in general can only be achieved in the water discharge standard, and one-step integration of membrane bioreactor equipment, not only from a sewage treatment to the reclaimed water changes, and cost less than Desalination And South. It allows treatment to improve the water environment is not only a Environmental protection Industry, will be to provide clean water for industry. This low energy consumption of membrane - water resource bioreactor new technology and engineering has thus been a National Science and Technology Progress Award. Membrane separation technology that will combine with the new bio-technology wastewater treatment effluent quality is good, covers an area of provincial and stable operation, is most concerned about water resources in recent years of technologies. Application of membrane bioreactor technology can make major pollutants in wastewater removal rate above 90% water without suspended solids, turbidity is close to zero, the water quality good and stable, can be directly reused. Tsinghua University, Chinese Academy of Sciences Ecological Environment Research Center, Tongji University and the Beijing Science and Technology Co., Ltd. in the clean water source "863" and so the support, after years of joint research, to achieve the film - bioreactor technology, engineering . The project was developed with independent intellectual property rights of three low-power film - bioreactor (bed type, split type air-lift loop, flat plate) and three different forms Membrane Unit. With the existing membrane - bioreactor compared to low energy membrane - membrane bioreactor operating flux increased significantly, reaching the international advanced level of well-known enterprises. In addition, the researchers also developed a series of membrane fouling control technology: proposed economic aeration and sub-critical flux operation mode of the membrane in different forms - in both the bioreactor was well applied, can effectively control the membrane surface sludge deposition; developed a dosing Coagulant And oxidant mixture of regulation and control of membrane filtration technology to extend the operation period film 2 to 4 times; developed two kinds of automation suitable for different size and degree of membrane fouling-line chemical cleaning mode, and has been applied in practical engineering. For urban sewage nitrogen and phosphorus removal, residential sewage and bath wastewater reuse, and printing and dyeing wastewater treatment hospital, tobacco and other industrial wastewater treatment and reuse, such different requirements, the researchers developed different film - combination of bioreactor technology can meet a variety of wastewater treatment or recycling goals. Compared with conventional activated sludge, COD removal 90%, COD loading rate increased 3 to 5 times, the area down to 1 / 5 ~ 1 / 3. As the technology matures, the project is accelerating the industrialization process, the product price declines, applications have been extended, the old "aristocratic" products should be a "fly into the homes of ordinary people." The world's largest membrane bioreactor net water Chemical industry Cheng in Beijing Wenyu River Water Utilization Project of Shunyi New City (10 tons / day) was applied, but also opened the film treatment of municipal wastewater and sewage situation. It is understood that the first daily treatment in Asia for more than 10,000 tons of large-scale municipal wastewater membrane bioreactor engineering Beijing Miyun water recycling plant (4.5 tons / day), conciliatory recycling plant (35,000 tons / day) sewage treatment plant in Wuxi Shuofang (20,000 tons / day) and many other large-scale water resource project has successfully applied the results. Present, the discussion group has been authorized 17 national invention patents, research results in a large Urban sewage treatment , Residential sewage, hospital sewage and industrial wastewater treatment and reuse has been a large-scale promotion and application of total treated water volume at the end of 2008 more than 230,000 cubic meters / day.
