摘　　要：采用聚乙烯醇（PVA）-硼酸法制作固定化活性污泥小球,用正交试验确定降解对氯苯酚的固定化活性污泥的最优化条件。从温度、浓度和pH3方面比较了固定化活性污泥和游离活性污泥对对氯苯酚降解效果的影响。研究表明：固定化活性污泥降解对氯苯酚的最适宜温度为25～35℃,最适pH为6～8;固定化活性污泥对对氯苯酚的降解速度大于游离活性污泥。Activated sludge balls were immobilized in the PVA-boric acid with embedding, The optimal condi-tions of the immobilized microbial was obtained by the cross-test experiments, The removal efficency of 4-chlorophenol with immobilized activated sludge and free activated sludge was compared at different conditions of temperature, pH and the quantity of microorganism, The results showed that the degradation efficiency of immobilized activated sludge was apparently superior to that of free activated sludge, and the optimal conditions of degrading 4-chlorophenol was temperature 25～35 ℃,and pH 6～8.
