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