| Abstract: | Aerated hollow fibers membrane bioreactor process for municipal wastewater treatment was researched in this paper.Results under different operating conditions show that it is technically feasible to treat domestic sewage with this system.Under stable operating conditions of flux 10.4L/(m2·h),sludge retention time 20 days and sludge removal loading rate(COD/VSS)0.22kg/(kg·d),high quality effluent (COD<20mg/L,NH3-N<1.0mg/L,no color nor odor,no E.coli)was got without any chemical washing during the whole membrane life(three to five years).Sludge removal loading rate,system stability and flow state in the bioreactor are the major factors that could affect membrane washing period. |
