| 摘 要： | 以模拟西北集雨窖水水质的配水为原水,对生物过滤中强化自然挂膜的生物膜形成过程进行了研究.分析了膜形成过程中COD、NH3-N、浊度等的去除效果以及滤柱不同高度水头损失的变化和滤柱生物量的变化,并对膜形成过程的影响因素进行了讨论.结果表明,挂膜20 d后COD的去除率趋于稳定,去除率达到30％左右,30 d后浊度和氨氮去除率趋于稳定,分别达到90％和80％,可以用COD和NH3-N的去除率作为生物膜成熟的评价指标. |

| Abstract: | The enhanced biofilm formation of biological filtration in natural cultivation process was studied by simulating northwest cellar rainwater for raw water. Removal efficiency of COD, NH3-N, turbidity and the changes of head loss and biomass at different height of filter column were analyzed in the process of biofilm formation. The factors affecting biofilm formation process are discussed. Results showed that COD removal rate is became stable after the biofilm hanging 20 d, the removal of turbidity and ammoni... |
