针对大庆油田含油污泥特点，采用热洗法进行处理。为了增强脱油效果，投加有机阳离子絮凝剂对其进行有效调质。本文以环氧氯丙烷、三乙醇胺、三乙烯四胺（作为交联剂）为原料，采用水溶液聚合法制备有机阳离子絮凝剂，考察环氧氯丙烷与三乙醇胺摩尔比、三乙烯四胺用量、聚合温度、聚合时间对脱油率的影响。确定了聚合物最佳合成条件，并将其应用于含油污泥热洗法处理中，同时确定最佳使用条件。结果表明：聚合物加量为160mg/L，pH值为7时，与现场破乳剂同时加入，含油污泥脱油率可达82.83%，高于其他现场絮凝剂与破乳剂的联合加入，是一种有效的絮凝剂。SEM 电镜分析表明：加入絮凝剂后，污泥絮体排列紧密，有利于污泥絮凝脱油。

According to the characteristics of oily sludge in the Daqing oilfield,the hot washing method was used for its processing. In order to enhance oil removal,an organic cationic flocculant was added for conditioning. The organic cationic flocculant was synthesized by aqueous solution polymerization of epichlorohydrin and triethanolamine with triethylenetetramine as modifying agent, and the influence of molar ratio of epichlorohydrin to triethanolamine,amount of triethylenetetramine, polymerization temperature,and reaction time on oil removal for oil sludge was investigated. The optimum synthesis conditions of the flocculant were determined,and the best conditions of hot washing in the treatment of oily sludge were also determined. The flocculant dosage was 160mg/L,pH was 7,when it was added simultaneously with field demulsifier,oily sludge removal rate was up to 82.34%,higher than the combined use of other flocculants and demulsifier. SEM analysis showed that after adding the flocculant,sludge flocs arranged closely,which was favorable for sludge flocculation.
