油田钻井废水处理技术与研究

针对油气田钻井产生大量的固体废弃物渗滤池中钻井废水处理的问题，利用化学混凝沉降兼氧化还原法处理固废渗滤液进行了实验研究。实验结果表明，经过调整渗滤液pH值．加入聚合氯化铝铁及助凝剂PAM，进行絮凝沉降，再用芬顿试剂氧化，可以处理高浓度废水，特别是对CODcr、色度等指标的控制，达到污水综合排放标准。

Technology and Research of Drilling Wastewater Treatment in the Oilfields

In view of the problem of drilling wastewater treatment in filtration tank where there are a large number of solid wastes produced by the drilling production of oil and gas fields,chemical coagulation settlement and oxidation-reduction process are experimentally applied to the treatment of solid waste filtration fluid. The experiment result indicates that high concentration wastewater can be treated and reach the comprehensive discharge standard of sewage,especially the index control of CODcr and chromatici...
