一、概述炼油厂一般废水量都很大,水质也较复杂。除含有各种油品、苯类和其它有机溶剂外,还含有酚类化合物、硫化物、氨氮、环烷酸、无机盐类和各种悬浮物等,其中主要污染物有油、硫、酚等。目前炼厂废水处理多采用隔油,浮选*生化的流程,一般可达到工业“三废”排放标准。但这种流程仍不能完全消除污染,还会产生浮渣 First, an overview of refinery wastewater are generally large, water quality is more complex. In addition to containing a variety of oil, benzene and other organic solvents, but also contains phenolic compounds, sulfide, ammonia, naphthenic acid, inorganic salts and various suspended solids, etc., of which the main pollutants are oil, sulfur, phenol Wait. At present refinery wastewater treatment and more use grease, flotation * biochemical processes, generally can reach the industry “three wastes ” discharge standards. However, this process still can not completely eliminate the pollution, but also produce scum
