活性污泥对四种非极性有机物的吸附

Sorption of four non-poplar organic compounds by activated sludge

以苯酚、氯仿、氯苯和萘作为目标有机物 ,进行了活性污泥吸附非极性有机物的试验研究 ,根据活性污泥对非极性有机物的吸附由表面吸附和分配两个部分组成的假说 ,建立了相应的数学模型q =k1C1 ne +k2 Ce,试验结果与模型比较吻合 .

An investigation was conducted to study the sorption of non\|polar organic compounds by activated sludge using phenol, chloroform, chlorobenzene and naphthalene as target organics. Based on the hypothesis that the sorption of non\|polar organic compounds by activated sludge is consisted of surface adsorption and partition, a model, q=k 1C 1/n e+ k 2C e, was established. This model was found to be adequate for describing the sorption of the four non\|polar organic compounds by activated sludge.
