高级氧化技术处理石化废水的研究进展

Research Progress of Advanced Oxidation Processes for Treatment of Petrochemical Wastewater

石化废水是石化企业用石油或石油副产物生产烯烃等化工原料和合成各种有机化学产品所排出的废水。目前主要采用生物法进行处理。但是因为石化废水的量大,有机物含量高,传统的生物处理法中的微生物活性会受到抑制,导致某些石化废水处理不经济,有些排出废水水质不能满足要求。综合了近几年国际国内对于石化废水处理的研究状况,介绍了几种高级氧化法的优缺点,并指出未来对于石化废水处理的研究重点和方向。

Petrochemical wastewater is discharged from the petrochemical enterprises. At present, the wastewater is mainly treated with biological methods. However, the amount of petrochemical wastewater is huge, and organic matter content is high, so the microbial activity of traditional biological treatment will be inhibited. Some petrochemical wastewater treatment is not economical, and the quality of treated wastewater is not up to standard. In this paper, the research status of petrochemical wastewater treatment in recent years was introduced. The advantages and disadvantages of several advanced oxidation methods were discussed, and future research direction of wastewater treatment was pointed out.
