摘　　要：针对后期油气勘探钻井废水COD超标率高的现状 ,开展了钻井废水深度氧化处理的室内研究 ,筛选了氧化剂 ,并确定了催化剂 ,重点探讨了深度氧化处理的条件。室内试验研究表明 ,经一步混凝法处理后的钻井废水再经H2 O2 进行氧化处理 ,同时辅助FeSO4·7H2 O作催化剂 ,控制好各种氧化条件 ,对原水 (一步混凝法处理后 )COD小于 1 0 0 0mg/L的处理水 ,氧化处理后基本能达到COD值≤ 1 0 0mg/L 。For high exceed standard rate of COD on drilling wastewater in oil and gas field drilling and exploration,indoor research has been done on depth oxidation treatment of drilling wastewater.Through the experiment,Oxidant is selected and catalytst is determined at the same time,and the condition of depth oxidation treatment is discussed.The result of experiment shows that drilling wastewater was handled by first-step coagulation and floccutation treatment again through depth oxidation treatment with H 2O 2 and catalytic with Fe 2+ ,and the optimization oxidation condition is selected and controled at the same time.For treating raw water(that of first-step coagulation and floccutation process)with COD is less than 1000mg/L,it is satisfying COD≤100mg/L by depth oxidation treatment and satisfying nation effluent standard.
