摘　　要：对采用气浮/水解酸化/接触氧化/混凝沉淀工艺处理印染废水的改造工程实例进行了介绍。运行结果表明,当进水COD、BOD5、SS和色度的浓度分别为1680mg/L、430mg/L、450mg/L、600倍时,出水浓度分别为80mg/L、30 mg/L、40mg/L、50倍,可达到国家《纺织染整工业水污染物排放标准》(GB 4287-2012)间接排放标准。Air floatation/hydrolysis acidification/biological contact oxidation/Coagulation sedimentation process was used to treat printing and dyeing wastewater.The results indicated that the effluent concentrations of COD,BOD5,SS were 80 mg/L,30 mg/L,40 mg/L,50 times when the infl uent concentrations of COD,BOD5,SS were 1680 mg/L,430 mg/L,450 mg/L,600 times respectively.It suggested that the effluent could meet discharge standards of water pollutants for dyeing and fi nishing of textile industry for indirect emission standard(GB 4287-2012).
