摘　　要：定影漂白废水用铁蓝法预处理,结果表明,以硫酸亚铁为沉淀剂,投加量为铁氰化物理论值的1.3倍,CN^-去除率为98％,反应生成的普鲁士蓝纯度较高,可供综合利用。铁蓝法除CN^-后的出水与显影冲洗废水混合,再经活性炭生物膜法处理,COD_(Cr)去除率为80％。Using ferrous-activated carbon biological membrane to treat the colour film rinsing wastewater has been studied. It was found that when used ferrous sulfate as precipitant, its feed amount was 1.3 times of the theoretical value, then the removal rate of CN- could be 98%, and the reacted product potassium ferric cyanide was of higher purity, and could be reused. After removing CN-, treating the mixture of effluent and developing wastewater with activated carbon-biological membrane, the removal rate of CODcr and BOD5 were 80% and 90% respectively.
