油气井压裂施工中所产生的压裂返排液 ,先用混凝 -微电解 -吸附预处理 ,再用生物法处理。结果表明 ,生物法处理后能使压裂返排液COD值降至 10 0mg/l以下 ,使压裂返排液达到排放标准。
Fracturing fluid produced during the fracturing of oil and gas wells is first pretreated by coagulation-microelectrolysis-adsorption and then treated by biological method. The results show that after the biological treatment, the COD value of the fracturing fluid can be reduced below 10 0 mg / l, and the fracturing fluid can reach the discharge standard.
