摘要
针对铝盐系无机混凝剂（如硫酸铝、聚合铝）用于含油废水脱油净化处理而产生的含油浮渣，提出了一种使含油浮渣资源化综合利用的无机酸直接酸化处理的工艺方法。本处理工艺的特点在于：①可以充分回收原油；②循环使用铝盐混凝剂；③免除对含油浮渣饼的焚烧处理过程。铝盐混凝剂经５次循环使用，仍保持很好的除油效果。
In the light of inorganic coagulants in aluminate series(aluminum sul-fate,polymerized aluminum chloride,etc.)used to deoiling purification of oily waste wa-ter producing oily scummings,this paper refers to direct acidizing process with inorganic acids to make oily scummings converted into comprehensive utilization resource.The characteristics of this treatment processare:a.fully recover crude oil;b.cyclically use aluminate coagulants;c. avoid incineration process of Oily scum cakes.The aluminate co-agulants after utilization for five times still keep very good deoiling results.
