摘要
采用聚合氯化铝(PAC)和阳离子聚丙烯酰胺(PAM)复合混凝安乃近废水,在pH为6.8,PAC与PAM的用量分别为200mg/L和8mg/L时混凝效果较好。混凝后的废水再用H2O2/Fe2+/UV体系氧化,当pH为3时,采取三次投加方式加入H2O2,紫外灯照射6h,取得了满意的结果。经该方法处理后的安乃近废水,其COD去除率为99.2%,脱色率达100%,达到了医药行业的废水二级排放标准。
The process of adsorption-coagulation-advanced chemical oxidation was used to treat analgin wastewater, and the best condition of coagulation and oxidation are selected. Under the condition of pH=6.8, the effect of the coagulation treatment on the wastewater is better when PAC and PAM were used as coagulation and their feeding amount were 200mg/L and 8mg/L, respectively. Then when pH was 3, the wastewater treated above was oxidized by H_2O_2/Fe^(2+)/UV. When the exposure time of UV-light was 6h, the satisfactory treatment effect was obtained. Experimental results that, for analgin wastewater, the removal ratio of COD was 99.2% and decolourisation rate was 100% by using the process. The analgin wastewater treated can reach the second effluent standard of medical wastewater.
