摘要
稠油废水含大量难生物降解的大分子有机物,BOD_5/COD_(Cr)极低。文章简要介绍了稠油废水的有机组成和处理难点,总结了提高稠油废水可生化性的生物处理方法,对比了活性污泥法、生物膜法等生物法的处理效果和优缺点,探讨其降解机理,对提高稠油废水生物法处理效率提出了建议。
This article introduces the organic components and treatment difficulties of heavy oil wastewater,and summarizes the biological treatment methods of increasing biodegradability of heavy oil wastewater.By means of the comparisons of treatment effects,advantages and disadvantages between activated sludge and biofilm,the mechanism of degradation of biological treatment is discussed.Then suggestions are proposed to improve the treatment effects of heavy oil wastewater by biology.
