摘　　要：借助有机物红外光谱分析,探讨了采用电气浮法处理前与处理后废水中有机物的结构变化情况,并对电气浮法去除钻井废水COD的机理进行了初步探析。结果表明,某些有机物如磺化沥青在采用电气浮法处理前与处理后其分子结构发生了很大变化,在一定程度上被氧化降解,其去除以电解氧化还原作用为主,电解絮凝和电解气浮作用为辅;而某些有机物主要是在电解絮凝和电解气浮作用下去除的。The changes of the structure of the organics in wastewater before and after electrocoagulation-flotation treatment has been studied by infrared spectral analysis.Some organics such as sulfonated bitumen,the structure of those had changed a lot and these organics had been oxygenized and degraded.The mechanism was mainly depending on electric oxidation reduction and electrocoagulation and flotation played secondary role.However,some organics were removed mainly by electrocoagulation and flotation.
