摘要
进行了生物造粒流化床对城市污水脱氮除磷效果的试验。试验结果表明,生物造粒流化床对TN、NH3-N、TP的去除率分别达53.5%、41.6%和95.1%。氮的去除可以用微环境理论来解释,而除磷主要通过化学作用。
The experiment on the effect of nitrogen and phosphorus removal of municipal sewage by biological pellet fluidized bed was carried out. The ! results showed that the removal rate of TN, NH3-N, TP by biological pellet fluidized bed reached to 53.5%, 41.6% and 95.1% respectively. It is held that nitrogen removal by biological process could be explained with the theory of microenvironment, while phosphorus removal is mainly due to chemical phosphorus removal.
