摘　　要：分别选取产朊假丝酵母、活性炭和紫外光照三种不同方式对不同浓度的含硝基苯污水进行处理,探索其去除规律。实验结果表明:三种处理方式对水体中硝基苯均有去除作用;从去除效率角度考查,活性炭吸附适于硝基苯浓度较高的前期处理,中等浓度水体则应采用酵母生物吸附,当浓度较低时应用紫外光解效率最高。Depurative principles were studied by the way of biosorption of candida utilis, physical adsorption of active carbon and photolysis for nitrobenzene sewage in this paper. The results showed that the three ways all had the removing effect on nitro- benzene sewage, The adsorption of active carbon was applicable for pretreatment of concentrated nitrobenzene sewage, biosorption of yeast should be adopted in moderate concentration nitrobenzene sewage, and the photolysis is very efficient for low concentration nitrobenzene sewage.
