At present, it is so prominent in the development of the petrochemical industry in China，and it is accompanied by petrochemical wastewater, which has become a big problem need to solve urgently.Because petrochemical wastewater mainly contains benzene-compound, organic matter, high salt wastewater and oil sewage, etc. They are very damaging and highly contaminated. The composition and properties of the petrochemical wastewater were introduced firstly, the current situation of petrochemical wastewater treatment at home and abroad were reviewed in the study. Especially the development of petrochemical industry in sichuan was introduced. Based on the present situation and the existing problems, put forward some countermeasures and expect technique develop direction in the future.

The results showed that DOC, UV254 and SUVA all presented a characteristic that organics was mainly concentrated on molecular weight <1kDa.Except organics with molecular weight <1kDa, the molecular weight of organics in Influent and effluent of Hydrolytic Acidification respectively distributed in the range of <1kDa, 30~100kDa and 1~3kDa, 10~30kDa. Organics in effluent of Anaerobic, Aerobic, Secondary sedimentation tank and Contact oxidation occupied proportions in all ranges of molecular weight distribution but relatively lower.
