摘　　要：以西北某炼化企业二级出水为研究对象，研究了铁炭在水中微电解作用有效降解CODCr的作用机理。通过微电解降解炼油二级出水CODCr实验，确定了最佳工艺参数：Fe／C质量比为3：2，海绵铁投加量为15g／L，反应时间为2．5h，反应pH为3，填料粒度范围在1—2mm。在最佳参数运行下，出水CODCr去除率高达75％以上，达到了《城市污水再生利用工业用水水质》（GB／T19923—2005）出水水质要求。Setting the secondary effluent of a certain refinery in northwest China as the research object, the author researches the mechanism of ferric - carbon micro - electrolysis action to degrade CODer effectively in water. De- grade CODcr of refining secondary effluent by means of micro - electrolysis experiments, meeting water quality re- quirements, ＂ The reuse of urban recycling water - Water quality standard for industrial uses （ GB/T 19923 - 2005 ）＂. At last to define the optimum craft parameters by experiments： the mass ratio of Fe/C is 3：2, the dosage of sponge iron is 15g/L, the reaction time is 2.5h, the pH of the experiment is 3, the packing particle size range is 1 -2mm. Under the optimum operation parameters, removal rate of the effluent CODcr reaches up to 75%, which also enhances the biodegradability of waste water.
