摘　　要：采用光助Fenton法处理中药浸膏药渣渗滤液。实验结果表明,在光照时间120 min、pH值为5、H2O2与COD化学计量比为1、Fe2+与H2O2摩尔比为0.07时,色度、COD去除率均达到最大,分别为92%,76.4%;紫外灯光较太阳光相比对色度、COD去除较好;COD去除效率随原水初始COD浓度的增加而减少。Chinese herbal medicine residues leachate is treated by a photoassisted Fenton reaction.The results show： When optimum conditions are obtained with 120mins of illumination time,pH value of 5,molar ratios of COD∶H2O2=1∶1 and Fe^2＋∶H2O2=0.07∶1,the removal rates of colority and COD is maximum,respectively reaching 92% and 76.4%.Colority and COD removal rates are both higher by ultraviolet than by sunlight.When COD initial concentration becomes higher,COD removal rate is smaller.
