微电解-Fenton氧化-絮凝组合工艺处理油田压裂废水
Treatment of oilfield fracturing wastewater by combination process of micro-electrolysis-Fenton oxidation-flocculation
摘要
Abstract
The oilfield fracturing wastewater was treated by combination process of micro-electrolysis-Fenton oxidation-flocculation,and the process conditions were optimized. The experimental results show that:Under the optimum process conditions of initial wastewater pH 3.0,iron filings dosage 1.5 g/L(the mass ratio of iron filings to activated carbon is 1∶1),micro-electrolysis time 80 min,Fenton oxidation time 120 min,H2O2 dosage 940 mg/L and cationic polyacrylamide dosage 120 mg/L,the wastewater COD is dropped from 3 116.0 mg/L to 681.3 mg/L with 78.1% of total COD removal rate and 33.1%,37.9%,7.1% of COD removal rate of the three processes respectively, and the effluent water quality meets the on-site injection standardof SY/T 5329-2012;The treatment effect of the combination process is much better than that of micro-electrolysis,Fenton oxidation or flocculation process,and the process is a simple method with high utilization rate of chemical reagents.关键词
