摘要
以钼改性高岭土为催化剂,采用电化学降解的方法处理造纸废水,研究了造纸水初始pH、矿化度、催化剂负载不同离子对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为4时COD去除率最好,达到90%以上。
The electrochemical degradation papermaking wastewater catalyzed by metal ion supported on molybdenum modified kaolin in the electrochemical reactor has been investigated.The effects of initial pH,metal ion and NaCl on the efficiency of the electrochemical degradation process were studied.It was found that the modified kaolin loaded Fe3＋ had the highest electrochemical catalytic activity when the electrochemical degradation papermaking wastewater pH was 4.Its COD removal rate could be up to 90%.
