Abstract: In the experiment the wastewater composition complex, contains a large amount of furan ring kind substances is a mixture of a variety of wastewater. Wastewater pH value in 1.6, the COD value in the 2.0×105 mg/L fluctuations, and salinity can up to 13%. According to the situation of water quality, using microelectrolytic method to the wastewater pretreatment, and grope for the optimum process conditions.The experimental results show that wastewater pH value is 3, carbon iron mass ratio is 1∶2, the reaction time is 3 h, the iron carbon add content is 1%, micro electrolytic process for the furan ring kind of wastewater treatment effect is good, COD removal rate can reach 57%, the total color removal rate can reach 80%.

摘要： 实验中所采用的废水组成复杂,含有大量的呋喃环类物质,废水的pH 值在1.6左右,COD值为2.0
暳105 mg/L左右,盐的质量分数可达13%。针对水质情况,利用微电解等方法对该废水进行了预处理,并摸索了最
佳工艺条件。实验结果表明,废水pH 值为3、碳铁质量比1暶2、反应时间为3h、铁碳质量分数为1%时,微电解法对
该呋喃环类废水处理效果较好,COD总去除率可达57%,色度去除率可达80%。
