炼油厂碱渣废水的污染评价及预处理

Pollution and pretreatment of refinery basic sewage

针对炼油厂碱渣废水成分复杂和难生化的问题 ,对其主要污染物的污染和可生化性情况进行了评价 ;并采用UASB -AF反应器水解处理 ,运行结果表明 ,经过厌氧水解处理 ,提高了碱渣废水的可生化性 ,降低了碱渣废水的污染程度 ,减轻了碱渣废水对后续生化处理系统的负荷。

Aiming at serious pollution and no good biochemical quality in refinery basic sewage,the pollution status and biochemical quality of the sewage were analyzed.The results showed that the pollution of the sewage was reduced,the biochemical quality was improved,and the sewage overload to the waste water treatment system was lowered using UASB-AF reactor.
