摘　　要：用活性污泥制备灭活干污泥来与原活性污泥进行针对生活污水的吸附试验,比较两种污泥吸附能力的差别,分析生物作用对吸附的影响。发现温度对活性污泥的影响比对灭活污泥的影响大;两种污泥的吸附结果都能用伪一级和伪二级方程进行拟合;活性污泥比灭活污泥的吸附容量大,活性污泥和灭活污泥的最大吸附容量分别为101.01和35.46 mg/g。　Inactivated sludge prepared by drying activated sludge and the original activated sludge were used to adsorb pollutants in domestic sewage,the difference of the two kinds of sludge in adsorption capacity was compaired and the influence of biological effect on the adsorption was analyzed.It was found that,the influence of temperature on activated sludge was greater than that on inactivated sludge： the adsorption results of the two kinds of sludge both could be fitted by seudo-first and seudo-second order equations;the adsorption capacity of the activated sludge was greater than the inactivated sludge,the maximum adsorption capacity of them were 101.01,35.46 mg/g respectively.
