摘　　要：针对某轧钢厂的乳化液废水,采用破乳-絮凝-活性炭吸附的处理工艺,选用W25为破乳剂,PAC为絮凝剂,活性炭过滤,其出水水质达到二级排放标准。废水处理过程产生的浮油渣,可通过焚烧进行处理。The process of demulsification-floeculation-activated carbon adsorption is used in the treatment of the oily wastewater from a rolling mill. During the treatment,W25 is used as demulsifier and PAC as floeculant,then the water is filtered by activated carbon,whose effluent can reach the second-order emission standard.
