摘　　要：利用卷贝在合建式活性污泥反应器中摄食污泥进行污泥减量试验。试验发现,污泥表观产率系数与卷贝密度呈负相关,卷贝对污泥的相对减量约为40%,绝对减量为37.5mgVSS/(L·d),减量速度为0.177mgVSS/(mgP.acuta·d),活性污泥系统中卷贝的存在对COD、氨氮和总磷的去除不会产生影响,对污泥沉降性能也影响不大。Phusa acuta utilizes the sludge as nutrient at a composed activated sludge reactor, by this way the sludge yield was controlled. The experiment results shown that the apparent coefficient of sludge yield was negatively correlated to the density of Phusa acuta . There are a relative sludge yield reducing ratio of 40% , an absolute sludge reduction of 37. 5 mgVSS/(L·d) and a sludge reducing speed of 0.177 mgVSS/(mgP. acuta·d) for Phusa acuta . No effects of Phusa acuta to removals of COD, ammonia N and TP were observed and the effect to sludge settling seems small.
