摘　　要：随着采油废水产生量的逐渐增大以及排放标准的日益严格,寻找一种经济、高效的处理方法显得十分必要。采用铁炭微电解技术对冀东油田采油废水进行了处理。考察了铁屑粒径、pH值、Fe/C质量比和反应时间对COD去除率的影响并设计了正交实验,结果表明,影响微电解工艺的因素主次关系为:pH>Fe/C质量比>反应时间,在最佳条件pH=5,Fe/C质量比为7∶1,反应时间50 min下,原水COD由170 mg/L降至95.6 mg/L,去除率达43.85%,出水满足国家二级排放标准。With the increase of oilfield wastewater and the increasingly strict requirement of discharge standard,it is necessary to search for an economical and efficient treatment method to achieve standard discharge.Iron-carbon micro electrolysis technology used to treat Ji Dong Oilfield wastewater was studied.The factors that affect the COD removal efficiency including particle size of iron scale,pH,Fe/C mass ratio and retention time were analyzed.Orthogonal experiments were also carried out to determine the order of different factors and optimal conditions as follows： pH Fe/C mass ratio retention time;pH=5,Fe/C mass ratio=7∶ 1,retention time=50 min.Under optimum conditions,COD removal efficiency was 43.85% and the effluent water met the second class national wastewater discharge standard.
