Research MBR wastewater treatment technology in the country and the application of membrane bioreactor, though started late, but rapid development. In 1991, Qin Yun Hua membrane bioreactor applications were reviewed, introduced MBR research situation in Japan, which is China's scholars membrane bioreactor done earlier reports. Subsequently, 江成璋 et al applied research hollow fiber ultrafiltration membrane in Biotechnology. 1995, 樊耀波 the MBR for wastewater treatment in petrochemical research, developed a laboratory-scale aerobic separate MBR. Since 1995, work began our research on membrane bioreactor wastewater treatment technology in full swing, a number of research institutes to carry out research in this area, Tsinghua University, Harbin Institute of Technology, Research Center for Eco-Environmental Sciences, Tianjin University, Tongji University and other operational characteristics of a membrane bioreactor, factors membrane flux, membrane fouling prevention and other cleaning done a lot of meticulous research. 2000 Nanjing hollow fiber membrane applications, Gu Ping hollow fiber membrane using domestic sewage done pilot-scale MBR Nanjing hollow fiber membrane price, results showed that: MBR process effluent suspended solids is zero, the total number of bacteria is better than drinking water standards , COD and ammonia nitrogen removal efficiency higher than 95%, the water can be directly reused. 2001, and so on-one 张立秋 MBR treatment of domestic sewage main design parameters of HRT, SRT and other theoretical derivation provides a reference for practical engineering design, and the film is jam-depth study was to investigate the mechanism proposed internal biological membranes blockage exists. With the promulgation of the new national standard of drinking water, water treatment process to put forward higher requirements. "Twelve Five" period Nanjing hollow fiber membrane materials, the state will invest 400 billion for upgrading water treatment plant. In this context, what kind of technology can effectively solve the water supply security problem? Held in the near future, "the eighth cross-strait water safety control technology and management Symposium 2013 Water Forum", Chinese Academy of Engineering, Harbin Institute of Technology Professor Lee Kyu White said: "UF able to remove almost all microorganisms in water, so drinking Water from the relative safety of bio-security made a leap towards absolute security, water purification process would inevitably lead to a major change, "Lee Kyu White pointed hollow fiber membranes, ultrafiltration combined process can improve the first-generation process (coagulation - precipitation - Filter - chlorine disinfection) of water quality and microbiological safety, but also can effectively solve the second-generation technology (ozone activated carbon) biological stability, will become the third generation of urban drinking water purification process core technology, ultrafiltration water treatment plant very broad application prospects.
