摘要/Abstract

摘要： 以活性艳兰K-3R染料废水为处理对象,采用增强型内电解-光催化组合工艺,对影响处理效果的因素进行研究,得出增强型内电解-光催化处理活性艳兰K-3R最佳的工艺条件。结果表明:增强型内电解处理活性艳兰K-3R适宜的工艺条件为:处理时间20 min、pH值4～6或8～10、液固比1∶1(mL∶g)。在此条件下,COD_Cr去除率达到80%左右,色度去除率达到95%以上。增强型内电解-光催化组合方法处理活性艳兰K-3R的适宜工艺条件为:草酸钠加入量4 g/L、液固比2∶1(mL∶g)、内电解时间20 min、光照时间20 h。在此条件下,COD_Cr去除率达到90%左右。

Abstract: With reactive brilliant blue K-3R as processing objects,the factors of the treatment process were studied by integrating improvedinner electrolytic-photocatalytic and the optimum conditions were obtained.The results showed that the optimum conditions for the treatment of reactive brilliant blue-K-3R wastewater byimproved inner electrolytic process were as follows:treatment time is 20 min,pH isabout 4~6 or 8~10,and the ratio of liquid and solid is 1∶1 (mL∶g).Under this condition,the removal rates of COD_Cr and decolorizaiton can reach 80% and 95%,respectively.The optimum conditions for the treatment of reactive brilliant blue K-3R wastewater by improved inner electrolytic-photocatalytic process are that the addition ofNa₂C₂O₄ is 4 g/L,the ratio of liquid and solid is 2∶1 (mL∶g),treatment time of inner electrolytic is 20 min,radiation time is 20 hours,pH is about 4~6.The results showed that the removal rates of COD_Cr can reach about 90%.
