摘　　要：钻井污水是油田开发中的主要环境污染物之一。其成分复杂,使得CODCr值高而处理难度大。以渤深6井为研究对象,采用混凝与微电解相结合处理废水。试验结果表明,原水的CODCr从35 155 mg/L降到186 mg/L,达到二级排放标准。Drilling wastewater is one of main pollutants during the oilfield development. The constituents of the wastewater are complex, it is very high of CODCr and hard to dispose the drilling wastewater. The drilling wastewater of 6 Boshcn was takes as an example. The following two processes were have achieved： coagulation and micro electrolysis. It is proved that CODCr of the drilling wastewater declined from 35 155 mg/L to 186 ,ng/L, satisfy the Water Quality of Integrated Wastewatcr Discharged Standard.
