摘　　要：在回顾油气田钻井废水的来源、污染、处理状况的基础上,探索了钻井废水的处理工艺。研究表明,通过化学混凝法复合催化氧化技术处理钻井废水,CODCr为13200mg/L的钻井废液水经处理后,其CODCr值降为69.3mg/L,处理水质指标达到国家污水综合排放一级标准。从设计工艺过程可以看出,利用化学混凝复合催化氧化技术对油气井钻井废水进行深度达标处理,工艺简单,切实可行,能够实现零排放的要求,在一定程度上解决了油气井钻废水对环境的污染问题。所研制HNJ-1混凝剂及ASNG、HNZJ-1助凝剂、复合氧化剂YHJ-1对钻井废水进行处理效果好。Drilling wastewater processing has been discovered on the basis of reviewing the source,pollution and treatment of the wastewater. Study result indicates that,by combining catalytic oxidation with chemical coagulation treatment,the CODCr value of wastewater can be reduced from 13200 mg/L to 69.3 mg/L. The quality index of treated water achieves the first-class standard of National Integrated Wastewater Discharge Standard. According to its design process,this technology is simple and feasible for advanced treatment of wastewater. Also,it can meet the requirement of zero discharge so as to solve environmental pollution due to drilling wastewater to a certain degree. The developed agents of coagulating agent HNJ-1,agent ASNG and HNZJ-1 and complex oxidant YHJ-1 are efficient for drilling wastewater treatment.
