Abstract


The start of this year China's 12th five-year plan sends an important message: in the next few years will be committed to realizing wastewater zero emissions in China. In numerous can realizing wastewater zero discharge process, membrane technology is undoubtedly the most has the application prospect of the technology. The MBR process combined with the traditional biological treatment process and advantages of membrane technology, and become one of the preferred way to realize the goal of wastewater zero discharge. As the return of hot research field of anaerobic technology in recent years, anaerobic MBR technology is becoming more and more get the favour of academia and industry. This study examines the substrate and temperature on the pollutant removal ability of anaerobic MBR reactor, membrane pollution and its control, the influence of the sludge characteristics in three aspects. Substrate influenced the selection of pure VFA (acetic acid, propionic acid, valeric acid ratio for: three), and VFA (acetic acid, propionic acid, valeric acid three ratio:) both forms of composition of glucose as substrate main carbon source. The research results show that the removal of different substrates when anaerobic MBR did not differ between the COD removal efficiency. But the MBR VFA glucose wastewater treatment (2
