摘　　要：印染厂生产废水具有高浓度、高色度和含有大量难降解有机物的特点 ,用单一的化学法或生物法处理效果不好。江阴某印染厂采用物化 +三级生化 +物化法处理印染生产废水 ,设计处理能力 36 0m3 d ,废水进水CODCr,BOD5,SS和色度分别为 2 0 0 0～ 30 0 0mg L ,6 0 0～ 70 0mg L ,350～ 50 0mg L和 50 0～ 1 0 0 0倍 ,经处理后 ,出水稳定并达到污水排放一级标准。The wastewater from a printery features high concentration,high colority and high content of organics difficult to degrade.The use of only chemical method or biological method does not give good results of treatment.A physicochemical + three stage biochemical + physicochemical process was used in a printery in Jiangyin to treat the wastewater from the dyeing process with a design capacity of 360 m 3/d.If the COD Cr ,BOD 5,SS and colourity of the inluent were 2 000 ～ 3 000 mg/L ,600～700 mg/L,350～500 mg/L and 500～1 000 times respectively,the effluent can steadily meet the first class of wastewater discharge standard after treatment.
