摘要/Abstract

摘要： 针对变电站事故油池废水含有大量矿物绝缘油的特点,采用磁絮凝-电催化氧化组合工艺处理,对比磁絮凝与常规絮凝处理含油废水絮凝效果,重点研究电催化氧化工艺参数对含油废水中油去除率的影响。动态模拟试验结果表明,该组合工艺对变电站事故油池含油废水有较好的处理效果,油、化学需氧量、浊度和氨氮的去除率分别为96.99%、85.98%、90.85%和78.86%,出水水质达到《污水综合排放标准》一级标准要求。

Abstract: In view of the characteristics of the oil pool wastewater containing a large amount of mineral insulating oil in substation, the combined process of magnetic flocculation and electrocatalytic oxidation is adopted to treat the oil containing wastewater, the flocculation effect of magnetic flocculation and conventional flocculation is compared, and the effect of electro-catalytic oxidation process parameters on oil removal rate in oil-bearing wastewater is studied. The results of dynamic simulation tests show that the combined process has a good effect on the treatment of oil-containing wastewater from the oil pool of a substation accident. The removal rates of oil, chemical oxygen demand,turbidity and ammonia nitrogen are 96.99%,85.98%, 90.85% and 78.86% respectively. The effluent quality meets the first-class standard of Comprehensive Wastewater Discharge Standard.
