摘　　要：在水温为21．3～25．6℃、pH值为7．8～8．3、滤速为0．0345m／s的条件下，研究了生物滤池利用低有机物含量原水进行自然挂膜启动的过程，试验以生物膜生长与水质指标变化情况之间的关系为参考指标。结果表明：在低有机物含量条件下，可以直接采用原水进行挂膜，经过约38d生物滤池自然挂膜启动成功，但粗过滤环节的过滤效果不佳，这对滤池的生物处理效果有较大影响。The start-up process of the biofiher filled with raw water with low organic content was studied under the conditions of temperature of 21.3 to 25.6 ℃, pH of 7.8 to 8.3 and biofiher speed of 0.034 5 m/s. The relationship between the growth of the biofilm and the change of water quality was used as the reference index of biofilm formation process. The experiment results showed that the raw water with low organic content could directly be used for the formation of biofilm, and the start-up process needed a- bout 38 d. But the removal efficiency of the coarse filter was not good, which had a large effect on the bi- ological treatment effect.
