| 摘 要： | 采用Fe/C微电解耦合H2O2工艺对经复合混凝处理后的某页岩气井钻井废水进行处理，考察了Fe/C质量比、Fe/C投加量、溶液pH值、气水比、H2O2（30%）投加量和反应时间对COD去除率的影响。结果表明，耦合工艺最佳实验条件为Fe/C质量比1：1、Fe/C投加量500 g·L-1、溶液pH值2.5、气水比20：1、H2O2（30%）投加量6 mL·L-1、反应时间120 min。最佳工艺条件下，页岩气钻井废水经处理后，出水COD质量浓度为89.54 mg·L-1，去除率达到81.60%。

| Abstract: | Effluent of shale gas drilling wastewater from coagulation treatment was treated by Fe/C micro-electrolysis combined with H2O2 method. The effects of Fe/C mass ratio, Fe/C dosage, solution pH, air/water ratio, H2O2 (30%) dosage, and reaction time were investigated for their effects on COD removal rate. Optimum conditions were as follows:Fe/C mass ratio 1:1, Fe/C dosage 500 g·L-1, solution pH 2.5, air/water ratio 20:1, H2O2 (30%) dosage 6 mL·L-1, and reaction time 120 min. Under these conditions, the effluent concentration of COD reduced to 89.54 mg·L-1 and COD removal rate reached 81.60%. |
