摘　　要：用氯苯驯化污泥,发现经过短期的驯化,好氧活性污泥难以形成对氯苯的高效降解菌群,对氯苯的去除主要是污泥的物理吸附和生物吸附作用.实验结果表明,污泥吸附氯苯不但与污泥表面的孔隙有关,而且还与氯苯参与细菌菌胶体的形成有关.处于生长繁殖时期的污泥比处于非繁殖期的污泥吸附氯苯的能力更强..It has been found that, after short-term domestication of aerobic sludge by chlorobenzene, aerobic sludge is difficult to form highly efficient degradation flora for chlorobenzene and the removal of chlorophenyl is mainly by sludge physical and biological adsorption. The experimental result shows that： the reasons of chlorophenyl absorption relate to not only the surface pores hut also the lormation of colloidal that chlorobenzene and the bacterial strains involved. Bacteria in a period of growth and reproduction has more chlorobenzene absorption capacity than which is not in the breeding season.
