RESEARCH PROGRESS ON TREATMENT TECHNOLOGIES OF WASTEWATER CONTAINING NITROBENZENE

Nitrobenzene is a sort of priority pollutants characterized by chemical stability，high toxicity， refractory and biological accumulation． Pollution problems involved are being seriously concerned． This paper reviewed the research progresses in treatment technologies of wastewater containing nitrobenzene in recent years，elaborated the mechanisms of each technology， such as physical，chemical，biological and integrated methods of the degradation of wastewater containing nitrobenzene， evaluated their advantages and disadvantages in application at the same time． The study pointed out the future research direction． Emphases should focus on the effective combination of recent treatment technologies and the reducing of cost．
