渗滤液生化处理中原生动物群落变化的研究

采用厌氧好氧相结合的方式处理渗滤液,观察活性污泥驯化阶段原生动物种群的变化情况。结果表明,活性污泥中微生物的演化是从低等向高等方向进行的,出现的顺序依次是细菌、鞭毛虫、游动型纤毛虫、固着型纤毛虫、微型后生动物。从处理效果来看,驯化完成时,CODcr去除率为94%,氨氮去除率为83%,总磷去除率为67%。

The combination of anaerobic and aerobic treatment of leachate, observed the changes about protozoan populations of activated sludge acclimation stage. The results show that：The activated sludge microbial evolution is from the lower to the higher direction,in the order that the bacteria,flagellates,swimming ciliates,sessile ciliates,micro-metazoan. From the treatment effect, domestication is completed,the removal rate of C ODcr is 94%,the removal rate of ammonia nitrogen is 83%, the removal rate of total phosphorus is 67%.
