摘　　要：设计了微波辐射反应器,比较分析芬顿试剂降解、微波辐射降解、微波辐射和芬顿试剂共同降解3种情况下对含酚废水的降解率,微波辐射和芬顿试剂共同作用降解率最高;对微波辐射和芬顿试剂共同作用做单因素和多因素正交设计实验分析,最佳降解工艺条件是:选用添加2mL质量分数为30%的H_(2)O_(2)溶液,添加1 mL^(-1)浓度为20 mmol·L^(-1)亚铁(Fe^(2+))溶液、微波辐射功率640 W(功率密度1.32 W·mL^(-1))、微波辐射时间8 min和溶液pH值为3;在上述条件下,降解率可以达到90%以上。A microwave radiation reactor was designed,and the degradation rate of phenol-containing wastewater was analyzed under three kinds of conditions:only using Fenton reagent without microwave radiation,only using microwave radiation without Fenton reagent,and using microwave radiation and Fenton reagent together.The degradation rate was the highest under the combined action of microwave radiation and Fenton reagent.The single factor and multi-factor orthogonal design experiments were conducted to analyze the interaction of microwave radiation and Fenton reagent.The optimal degradation process conditions were determined as follows:2 mL H_(2)O_(2) solution with30%mass fraction,1 mL Fe^(2+)solution with 20 mmol·L^(-1) concentration,microwave radiation power 640 W(power density 1.32 W·mL^(-1)),microwave radiation time 8 min,pH value 3.Under above conditions,the degradation rate was above 90%.
