主要研究了膜生物反应器对冲厕海水中主要污染物的处理效果以及盐度对生物反应器内微生物群落和活性污泥特性的影响.结果表明,微生物经培养驯化后能适应不同的海水盐度,膜生物反应器对冲厕海水中的OOD和氨氮的去除率分别达到86%和93%.随着盐度的提高,污泥沉降性能变差.盐度的冲击对膜生物反应器处理效果有一定影响,系统需要较为恒定的盐度条件.
Treatment effect of seawater for toilet- flushing by the membrane bioreactor and influences of seawa-ter salinity on micro-organisms and activated sludge characteristics in the membrane bioreactor were studied in this paper.The results showed that micro-organisms after culture domestication could adapt to different sea water salinity, COD and ammonia nitrogen removal efficiency of seawater for toilet- flushing by the membrane bioreactor reached 86% and 9396, respectively.With the increase of salinity, sludge sedimentation performance deteriorated.The impact of salinity had a certain influence on the treatment effect of the membrane bioreactor, therefore the system needed a more constant salinity condition.
