摘要：

The effect of infiltration rate on microbial clogging and water quality changes is investigated experimentally using a sand column. The concentration of soluble COD [chemical O2 demand] in the effluent is stable during 3 mo. of infiltration; the lower the initial infiltration rate is, the higher the average percentage of the reduction of soluble COD becomes. The soluble COD is primarily removed in the surface layer. The hydraulic conductivity in the bottom layer decreases at the highest infiltration rate. The variation of infiltration rate is divided into 4 stages. The biological clogging model is proposed, the mechanism of biological clogging is discussed.
