摘要
采用大孔树脂吸附与电化学氧化联用技术处理了染料废水.考察了溶液pH值、吸附时间、树脂用量、电解时间、电解电压等因素对染料废水降解的影响.实验结果表明:大孔树脂选择性吸收了染料废水中的芳香族环类化合物,电解法对树脂吸附后的废水中残留的有机物去除有良好的选择性,反应速率快;整个系统扩大了对进水化学需氧量(COD)的适用范围,且总去除率可达99%,最终ρ(出水COD)小于0.10g/L.
In this study,dyeing wastewater was treated by that macroporous resin adsorption method combined with electrochemical oxidation process. The effects of the factors such as solution pH,reaction time of adsorption,volume of macroporous resin,electrolytic time,electrolytic voltage on degradation efficiency were examined. The results show that macroporous resin adsorbs aromatic compounds which were in the wastewater,then electrochmical oxidation process treats those remains very well,which were left from adsorption. the whole system makes greater range of COD of dyeing wastewater could be treated,and the COD removal of dyeing wastewater was approximately 99%. Finally the COD of treated wastewater was under 0.10 g/L.
