摘　　要：本文研究了邻二氯苯和邻氯酚生物处理过程中在活性污泥上的吸附特性及影响因素,通过测定等温吸附曲线,表明这两种有机化合物在活性污泥上的吸附符合线性吸附等温式:属于在疏水键力作用下的表面物理吸附,对难溶于水的邻二氯苯具有较强的吸附能力.This work studies the adsorption performance and influence factor of o-dichloroben-zene and o-chlorophenol to activated sludge in biological treatment process. By measuring isotherm curve. we can see that the adsorption performance of these two organic compounds conform to linear adsorption isotherm formular, that is, which belongs to surface physical adsorption under the action of hydrophilie bond and have better adsorption function to o-dichlorobenzene that is hard to dissolve in water.
