| 摘 要： | 以硫酸铝铁溶液为絮凝剂,高锰酸钾溶液为氧化剂,采用氧化絮凝的方法处理活性大黑染料废水,考察了絮凝剂与氧化剂用量比、絮凝时间、温度、pH等对脱色率和CODCr去除率的影响,确定最佳条件：絮凝剂与氧化剂的摩尔比为3.45∶0.14,pH=1,θ=30℃,絮凝时间t=1 h,脱色率可达99.13%,CODCr去除率达66.81%.如果采用两段处理法,脱色率可进一步提高到99.88%,CODCr去除率达85.13%.砖末二次吸附后,脱色率达99.24%,CODCr去除率达77.05%.

| Abstract: | The black activated dye wastewater was treated by oxidation-flocculation with iron aluminum sulphate as flocculant and KMnO4 as an oxidant.The influences of main factors on the decolorization rate and removal of COD have been investigated,such as flocculant amount added,oxidant amount added,flocculating time,temperature and pH value in wastewater.The results show that the optimum condition is： temperature 30 ℃,flocculating time 1 h,pH value 1,mole ratio of flocculant to oxidant 3.45∶0.14,with decolorization rate of 99.13% and COD removal rate of 66.81%.The decolorization rate will grow to 99.88% and the removal rate of COD to 85.13% by using a two-stage processes.When the wastewater is secondary treated by brick powders,the decolorization rate and the COD removal rate will reach 99.24% and 77.05% respectively. |
