含油污泥处理技术研究

Research on Oily Sewage Treatment Technology

针对某炼厂难以处理的含油污泥，用正交试验法对处理含油污泥的试验条件（破乳剂用量、提取剂用量、热水用量及加药方式）进行了研究，确定了先加污泥量１．０％破乳剂ＪＰ９９８搅３０ｍｉｎ，再加污泥量３０％的８０℃热水，再缓慢加入污泥量１０％的提取剂在８０℃下反应１ｈ，最后在２０００ｒ／ｍｉｎ下离心分离２０ｍｉｎ的实验条件和化学配方；据此化学破乳加机械三相离心分离技术处理后的含油污泥的原油回收率达９０％，油回收利用，水相重复使用或排入污水处理场。

As oily sewage of a refinery was hardly treated,experimental conditions of oily sewage treatment were tested by Zhengjiao tested method, in which quality of deemulsification agent,quality of extract agent,quantity of hot water and adding ways were researched.By means of chemical deemulsification and mechanical three phase's centrifugal separation technology,crude recycle rate of oily sewage was reached to 90%.The recycle crude was reused,the water phase was re utilized also or let to sewage treatment field,and the solid phase was reached to standard or buried.
