酸化-混凝-催化氧化联合处理钻井废液研究
Combined treatment of acidification-coagulation-catalytic oxidation of drilling waste
摘要
Abstract
The drilling wastewater from oil and gas field has been a problem of environmental risk for oil field management .In this experiment ,the oilfield drilling wastewater was put as the research object ,in which the COD value reached up to 67 920 mg/L .The preparation of a new coagulant PAZC and optimum conditions of chlorine dioxide catalytic oxidation process by acidifi-cation-coagulation-catalytic oxidation process were mainly researched .The COD value could be reduced to 126 .9 mg/L after treatment and achieved the secondary discharge standard of “Inte-grated Wastewater Discharge 8978-1996” .关键词
