摘　　要：采用微波诱导的高级氧化技术,活化Na_2S_2O_8产生·SO_4^-,对含DMP废水的处理进行了研究。以DMP为目标污染物,考查了Na_2S_2O_8投加量及反应时间等因素对DMP和COD去除率的影响。结果表明,微波诱导Na_2S_2O_8产生·SO_4^-降解DMP废水的最佳反应条件为:微波功率800W,100℃,m(Na_2S_2O_8):m(DMP)=0.6,加热140s,DMP和COD去除率最大,分别为72%和60%。The oxidation of dimethyl phthalate by sodium persulfate activated with microwave was investigated.The paper aimed at removing dimethyl phthalate(DMP)as a model pollutant,and researched DMP and COD were dealed by oxidant of Na2S2O8 concentration and reaction time,respectively.As a result,The optimum reaction conditions in microwave induced are:microwave power was 800W,the temperature was 100℃,the removal rate of DMP and COD was 72%and 60%respectivelywhen the ratio of sodium persulfate to dimethyl phthalate was 0.6after 140seconds.
