| 摘 要： | 采用混凝-二氧化氯法处理有机印染废水,可有效去除废水的色度,使废水达标排放.在实验条件下,先加入100 mg/L PAC,搅拌并静置60 min,然后加入60 mg/L ClO2,反应4 h后,色度、COD、BOD、SS、S2-平均去除率分别达到94.5%、88.3%、91.8%、76.5%、85.6%,实际应用中处理后色度、COD、BOD、SS、S2-平均去除率分别达到93.7%、85.2%、92.7%、71.4%、81.0%,符合国家GB 8978-1988《污水综合排放标准》.

| Abstract: | It is effective to decolor the chroma of printing and dyeing wastewater by using coagulation-chlorine dioxide process. The effluent can meet the requirement of discharge standard. Under the experiment conditions, 100 mg/L of PAC is added firstly,after stirring 60 main and adding ClO2 60 mg/L and reacting for 4 h,the average removal rate of chroma,COD,BOD,SS,S^2- are 94.5% ,88.3% ,91.8% ,76.5% ,85.6% respectively. In practical application,the average removal rate of chroma, COD, BOD, SS, S^2- are 93.7%, 85.2%, 92.7%, 71.4%, 81.0% respectively.The effluent quality conforms to the comprehensive effluent discharge standard GB 8978-1988. |
