摘要
对四川德阳某油气田的压裂返排液处理工艺进行实验研究。结果表明:经过铁碳微电解、芬顿氧化、活性炭-芬顿耦合联合工艺处理后,原水COD从4 000 mg/L降低到86 mg/L,达到GB 8978—1996《污水综合排放标准》石油化工行业一级排放标准。
The treatment of hydraulic fracturing flow back fluids from oilfield located in Sichuan was carried out experimentally by using integrated process composed of iron carbon micro electrolysis,Fenton oxidation,activated carbon. Removal rate of COD was investigated. The experimental results showed that initial COD degradation from 4 000 mg / L to 86 mg / L was observed,according with the first grade index of GB 8978—1996 'Integrated Wastewater Discharge Standard'.
