摘　　要：在不同pH和温度下,采用UV/Fenton法和石灰混凝法联合处理五倍子生产单宁酸产生的高浓度有机废水。结果表明:常温下(20℃)在UV/Fenton试剂反应阶段,Fe2+和H2O2的摩尔比为1∶6,反应30 min后,COD的去除率可以达到65.14%;经UV/Fenton试剂处理后的出水继续使用石灰混凝法处理,在pH=11,反应2 h后,最终出水的COD去除率可以达到70.36%.In the experimental, at different pH and temperature conditions, UV/Fenton reagent and lime coagulation were combined in use to process high concentrations of organic wastewater produced by Gall product tannic acid. The results show that： at room temperature （20 ℃）, during the UV/Fenton reagent phase, molar ratio of Fe^2＋ and H2O2 is 1：6, after 30min reaction, the removal rate of COD can reach 65.14%. After the UV/Fenton reagent treatment, the water treated by lime coagulation again, control the pH of 11, after 2 hours＇ coagulation and sedimentation, COD removal efficiency of final effluent can reach 70.36 %.
