摘要
分别采用Fenton法及氢氧化物沉淀-Fenton法对模拟电镀废水进行处理。结果表明:单独采用Fenton法处理模拟电镀废水,当废水pH值为3、Fe^(2+)与H_2O_2的物质的量比为1.1时,虽然废水中COD的去除率能够达到91.6%,但Zn^(2+)、Cu^(2+)、Ni^(2+)的去除效果并不理想。先采用氢氧化物沉淀法对模拟电镀废水进行预处理,再采用Fenton法进行处理,COD的去除率可以达到93.6%,同时Zn^(2+)、Cu^(2+)、Ni^(2+)三者的去除率也均能达到98%以上。
The simulated electroplating wastewater was treated by Fenton process and hydroxideprecipitation Fenton process, respectively. Results showed that when the simulatedelectroplating wastewater was treated by Fenton process, although the removal rate of COD inwastewater can reach 91.6% under the conditions of pH value 3 and nFe^2＋ = nH2O2=1. 1, theremoval effect of Zn^2＋ , Cu^2＋ and Ni^2＋ was not ideal. However, the simulated electroplatingwastewater was pretreated by hydroxide precipitation process and then treated by Fentonprocess, the removal rate of COD could reach 93.6%, and the removal rate of Zn^2＋ , Cu^2＋ andNi^2＋ could reach more than 98%.
