摘　　要：采用化学混凝—铁屑微电解法深度处理钻井污水。确定了最佳工艺条件 :铁屑与活性炭的质量比为 0 .5 ,反应时间为 2h ,污水 pH为 1.0 ,温度为常温 ,反应后用石灰乳调节污水pH至 12。处理后钻井污水COD可由原水的 80 6 5mg/L降至 4 30mg/L ,COD去除率大于94 % ,色度去除率达 10 0 % 。The chemical coagulation-iron scrap microelectrolysis process was used in removal of COD from petroleum drilling wastewater.The optimum process conditions were determined as follows:mass ratio 0.5 of iron scraps to activated carbon,reaction time 2 h,pH 1.0,normal temperature,regulating pH to 2 with lime cream after reaction.The COD in treated wastewater is reduced from 8065 mg/L to 430 mg/L with 94% of COD removal rate and 100% of colority removal rate.The treated wastewater can meet the national discharge standard of three grade.
