MBR technology in wastewater treatment abroad in research and application of membrane separation technology in wastewater treatment began in the late 1960s, the United States, # 1969 Smith et al. For the first time with the ultrafiltration membrane activated sludge method for combining municipal wastewater treatment technology research, the process boldly replaced with membrane separation technology in the conventional activated sludge secondary settling tank, the film has the physical characteristics of the efficient use of interception, so within the bioreactor to maintain a high concentration of sludge at F / M ratio low work, so you can get as much as possible so that the oxidative degradation of organic matter to improve the removal efficiency of the reactor, which is the first prototype of the MBR. Into the 1970s, research on the MBR further in depth, 1970 Nanjing sewage treatment flat membrane, Hardt, who use completely mixed with the ultrafiltration membrane bioreactor combined process sewage, won 98% of COD removal and 100% removal of bacteria results. 1971, Bemberis et al MBR wastewater treatment plant were tested and achieved good results. 1978, Bhattacharyya et al exceed membranes for municipal wastewater treatment, access to non-potable water reuse. 1978, Grethlein anaerobic digesters and membrane separation have been studied for the treatment of domestic sewage, BOD and TN removal rates were 90% and 75%. With the promulgation of the new national standard of drinking water, water treatment process to put forward higher requirements. Flat film "Twelve Five" period, 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 microorganisms in water can be removed almost entirely flat membrane Nanjing . Which is good, so that the biological safety of drinking water from the relative safety of the absolute security made a leap in the water purification process would inevitably lead to a major change "Lee Kyu White pointed out that the combination of ultrafiltration technology can improve the first-generation process (coagulation - sedimentation - Filter - chlorine disinfection) of water quality and microbiological safety mbr flat membrane technology, but also can effectively solve the second-generation technology (ozone activated carbon) biological stability, will become the core technology of the third generation of urban drinking water purification process UF water in very broad application prospects.
