| Abstract: | It is proven that Inorganic Membrane Bio-Reactor(IMBR)applied to domestic wastewater treatment is technically feasible and reliable during several months. In this study,under conditions of membrane flux between 75 and 150L/(m2·h),hydraulic retention time 5 hours,sludge retention time 5, 15, 30 days and velocity inside the membrane channel 4 m/s, the stable sludge concentrations(MLSS)in the bioreactor reach 3.1, 10.7and 17.3g/L after 10, 16 and 14 days respectively. Average removal rate of COD,NH3-N, and turbidity of the system are higher than 96%,95%and 98%,SS and E.coli.,100%. The effluent quality is always better than the quality standard for reuse issued by the Ministry of Construction in China. Moreover,fouling mechanisms of IMBR are also discussed in this paper. The initial permeability of inorganic membrane can be easily recovered over 90% after physical and chemical cleaning operations. |
