石油化工废水处理技术研究进展

Technologies for treatment of petrochemical wastewaters

石油化工废水组成复杂、浓度高、毒性强和难降解,对环境危害大。概括介绍了国内外石油化工废水的主要处理方法如物化法、化学法和生化法,并评述了各种处理方法的适用条件和处理效果,总结了各种处理方法的优缺点。最后,提出推行清洁生产,开展废水资源化,并用高效的末端治理方法处理废水,是石油化工行业水污染控制的出路。

Untreated petrochemical wastewaters are harmful to the environment since they typically contain many toxic and persistent organic pollutants in high concentrations. Physical, chemical, and biochemical treatment technologies effective for removing those pollutants are presented with their applicability, effectiveness and advantages. The best petrochemical wastewater management program should include cleaner production, wastewater use, and end-of-pipe treatment employing the most effective pollutant removal technologies.
