一体式膜生物反应器处理生活污水的试验研究

Study on the domestic sewage treatment with integral biomass separation membrane bioreactor

对一体式膜生物反应器处理生活污水时污泥活性变化情况和对污染物去除效果进行了初步研究,试验结果表明:该工艺处理生活污水时应采取一定的排泥措施;系统内生物种类和数量相当丰富;影响CODCr去除率的主要原因在于污泥活性,而影响NH3-N去除率的主要原因在于溶解氧浓度。

Sludge activity and removal efficiency of pollutants in the domestic sewage treatment with integral biomass separation membrane bioreactor have been investigated primarily. The results show that measures of discharging sludge should be taken. The kinds and quantities of microbe in the system are very plenty and the main factor that influences the removal efficiency of COD is sludge activity, whereas, the main factor that influences that of NH3-N is DO.
