摘要 运用催化臭氧化技术去除水中消毒副产物氯乙酸。结果表明:(1)Ni/Al2O3是一种高效催化臭氧化氯乙酸的催化剂;(2)催化臭氧化分解氯乙酸的效率,明显高于单独臭氧化和单独吸附去除氯乙酸效率之和;(3)低pH对氧化氯乙酸较为有利。 Using catalytic ozonation technique to remove water disinfection by-product chloroacetic acid and compare with adsorption ozonation, and studying the effect of catalyst, pH, time of catalytic oxidation conditions, changes on catalytic oxidation, and calculating the a-mount of ozone consumed, the result showed: ① Ni/Al2O3 was a high effective catalyst for catalytic ozonation of chloroacetic acid, ② efficiency of catalytic ozonation for decomposing chloroacetic acid was remarkably higher than ozonation and adsorption alone, and CD low pH was advantaged for oxidation of chloroacetic acid.
