摘要
通过试验方法,研究了混凝土生态膜污水处理工艺的循环挂膜过程,综合考察了混凝土膜片表面生物膜的生长变化情况,细菌数量及其微型动物的组成演化。同时在挂膜一定时间后投加生活污水,考察对COD、NH3-N的去除率。
The biofilm colonization process on eco-concrete sewage treatment was studied to investigate the regular change of biofilm development under different conditions, the increment of bacteria number as well as success of micro-animal kinds and population. The removal efficiency of CODcr and NH3-N was also observed.
