摘要
压裂返排液中由于含有大量有机添加剂,成分复杂,COD高,处理难度大。作者以某石化公司污水处理站的水基压裂液为研究对象,在对其水质特征进行分析的基础上,提出了预氧化-混凝-臭氧深度氧化复合处理工艺。实验结果表明经预氧化-混凝后的压裂返排液高锰酸盐指数去除率达82.3%,再利用臭氧深度氧化,三步复合工艺高锰酸盐指数去除率达86.5%,处理效果较好。
Fracturing liquid contains lots of organic additive,complicated composition,high COD,difficult to handle.This experiment research object is water-based fracturing fluid from a petrochemical company effluent treatment plant,on the basis of the analysis on the water characteristics,putting forward preoxidation-coagu-flocculation-ozone deeply oxidation composite process.The results show that after preoxidation-coagu-flocculation treatment,the CODOH-KI removal is 82.3%,then using ozone for deeper oxidation,CODOH-KI removal is 86.5%,fracturing Liquid has a good treatment effect.
