摘　　要：系统地阐述了钻井废水的来源、组成、污染特征及处理现状,并针对具体情况,设计了酸化-混凝-氧化的组合处理工艺。实验结果表明:酸化可以有效地降低钻井废水的COD值、色度和悬浮物;用PAC混凝沉降可进一步降低酸化处理后污染物的浓度,其中色度和SS可达到一级排放标准;采用Fenton试剂催化氧化可以使钻井废水的COD值达到一级排放标准。This paper expatiates the source,con- stitute,pollutant characteristics and the present condi- tion of disposing drilling sewage.Aiming at the con- crete waste,the disposal flow sheet of drilling wastewater has designed:acidification-coagulation- oxidation.Experimental results shows:(1)acidification can reduce the COD_(Cr)color and the content of suspen- ded solids;(2)after coagulation treatment,color and SS can be satisfied the standards of national wastewater discharge(GB8978-1996);(3)fenton oxidation can satisfied COD_(Cr)standard of national wastewater dis- charge(GB8978-1996).
