摘要：
Membrane bioreactor is a combination of membrane and sewage biological treatment technology, which is the new wastewater treatment technology. In this paper, the effect of pH and NH3-N load on membrane bioreactor for wastewater treatment is studied. Through the use of artificial mixed wastewater experiments, the results are as follows: The effect of pH on the effluent COD is not obvious, on the removal of NH3-N is very large. Taking into account of removal of organics and NH3-N, the pH should be controlled at 8.0. The removal rate of NH3-N decreased significantly with the increase of the NH3-N load. When the NH3-N load is 0.023 Kg/m(3).d, the removal rate reach the maximum value. In this case, the load of COD is 1.1 Kg/m(3). d.
