摘要:采用Fenton体系处理含有阿特拉津及酚类的废水,利用控制变量法,分别控制Fe2+的初始浓度,H2O2溶液初始浓度,以及不同[4-CP]0/[atrazine]0比例进行实验,通过二酚类对Fe3+的还原作用,实现了Fe2+/Fe3+之间自循环,使得在很低的Fe2+浓度下,污染物阿特拉津能持续快速地降解。经实验结果表明,Fe2+的初始浓度为0.05 mM,H2O2初始浓度为0.75 mM即[4-CP]0/[atrazine]0比例为4.0 时,废水中的阿特拉津和4-CP的降解效果最佳,阿特拉津去除率达95.6%,4-CP的去除率达95.7%。

Abstract: Initial concentration of the Fenton system to handle waste water containing atrazine and phenolic, the use of control variables France, respectively, to control Fe2 +, H2O2, initial concentration, and [4-CP] 0 / [atrazine] 0 ratio of experimentalreduction of Fe3+ by two phenolic of Fe2 + / Fe3 + from circulation, making a very low concentration of Fe2+, pollutants atrazine sustained, rapid degradation. The experimental results show that Fe2 + initial concentration was 0.05 mM H2O2 initial concentration of 0.75 mM [4-CP] 0 / [atrazine] 0 proportion was 4.0, atrazine and 4-CP wastewater degradation efficiency of atrazine removal rate of 95.6%, 4-CP removal rate of 95.7%.
