Abstract:
Comparison of treatment effect is investigated using individual membrane and membrane bioreactor(MBR) for micro polluted water. Hybrid of enhancement technique and MBR is also studied through ammonia chloride, glucose and powdered activated carbon(PAC) added. The results illustrate that the chemical oxygen demand(CODMn) and ammonia-N removal efficiency of individual membrane is 16% and 5% respectively. But the CODMn and ammonia-N removal efficiency of MBR reaches 35.3% and 44.5% respectively. Hybrid of microbial enhancement technique and MBR cannot obtain high removal efficiency for CODMn and ammonia-N by increasing the organic carbon and ammonia-N levels of raw water. 10% PAC renewed raises the CODMn removal efficiency from 35.3% to 50%.
