本文研究了三维电解-微电解-电芬顿氧化法处理阳极氧化染色废水的影响因素,分别考察了初始pH值、电压、电解时间以及H_2O_2用量对废水脱色率的影响。结果表明,控制铁碳颗粒投加量为5 kg·L^(-1),初始pH值为5,电解电压为50 V,对染色废水电解反应时间为120 min,H_2O_2的添加比例为1/500时,可以使阳极氧化染色废水脱色率达到99.8%。实验验证了三维电解-微电解-电芬顿耦合为一体式反应处理阳极氧化染色废水可达到快速脱色的目的,且工艺简单,可操作性强,具有较好的应用前景。

In this paper,the influence factors of treatment an anodic oxidation dyeing wastewater by three dimensional electrolysis-micro electrolysis-electro Fenton oxidation method were studied. The ef-fects of pH value,voltage,electrolysis time and H2O2 dosage on the decolorization rate of the wastewater were investigated. The results showed that the decolorization rate of the wastewater could reach more than 99.8% under the conditions that pH of 5,voltage of 50 V,time of 2 h and H2O2 dosage of 1/500. In conclusion,the experiment proved that the method could dispose the wastewater quickly,and have the advantage of simple process and strong operatibility. It has a good application prospects.
