摘要：
In this examination we have studied wastewater treatment for nitrogen and phosphorus removal using a membrane bioreactor with domestic wastewater. The results show that nitrobacteria was influenced greatly by pH, which we controlled between 6.5 to 7.0 (appropriate to nitrobacteria). The removal rate of NH4+-N is 99% and the concentration of effluent NH4+-N is below 0.5 mg/L; because of the high DO value in the denitration section, the denitrobacteria was restrained and the effluent TN value was high, but the removal rate of TN can also reach 80%; the removal of TP is due to sample sludge and microorganism growth.
