摘　　要：制备了负载型的钒改性高岭土催化剂,采用红外光谱(FTIR)、X射线衍射分析(XRD)手段对制备的改性高岭土进行了表征,并以钒改性高岭土为催化剂,采用电化学降解的方法研究了造纸水初始pH、造纸水中盐含量、催化剂负载不同离子对造纸废水处理效果的影响。研究表明改性高岭土负载铁离子作催化剂、pH=4时,COD去除率最好,达到约76%。The electrochemical degradation papermaking wastewater catalyzed by metal ion supported on vanadium modified kaolin in the electrochemical reactor was investigated.The catalyst was characterized by XRD,SEM and the effects of pH,the different metal ion,NaCl on the efficiency of the electrochemical degradation process were also studied.It was found that the modified kaolin loaded Fe3＋ had the highest electrochemical catalytic activity for the electrochemical degradation pulp and paper mill wastewater in pH 4.Its COD removal could reach up to 76%.
