摘要
利用固定化微生物取代活性污泥改进膜生物反应器来处理海水冲厕污水。结果表明,膜生物反应器改进后,微生物对温度、pH的适应范围增大,对CODMn、NH3-N的去除率提高,且膜污染大大降低,膜通量平均提高50%以上。在稳定运行阶段,系统对CODMn、BOD5、TOC、浊度、NH3-N的平均去除率可达96.7%、94.6%、95.4%、99.0%和98.8%,出水水质良好稳定。
The improved membrane bioreactor (IMBR) was applied to treat the seawater toilet-flushing sewage by substituting immobilized microorganisms for activated sludge. The results showed that the ability of resistance to temperature and pH was strengthened,the removal efficiency was increased,and the permeate flux was increased by over 50% in this system. During the stable operation stage,the average removal efficiency of chemical oxygen demand,biochemical oxygen demand,total organic carbon,turbidity and ammonia was96.7%,94.6%,95.4%,99.0%,98.8%,respectively.The effluent of this system was good and stable in quality.
