摘　　要：采用复相催化剂Y2O3/WO3对阜阳市污水处理厂综合废水处理进行研究,实验结果表明,固定光催化剂配比m(WO3)∶m(Y2O3)=1.470∶0.030、用量为0.400g,试液的pH=7.2,H2O2溶液用量为0.25mL,光照时间6h,综合废水的COD去除率达到82.7%,而相同条件下暗反应、空白实验反应综合废水COD去除率分别为18.5%、15.9%。该方法具有操作工艺简单,节省能源,所需设备少,处理彻底,氧化能力强,无二次污染等优点。The treatment of comprehensive waste water（CWW） by Y2O3/WO3 was studied.The result shows that the decolorizing rate of CWW can reach 82.6% under the condition： Y2O3/WO3,2.0%;amount of catalyst,0.400g;amount of CWW,50mL;pH,7.2;amount of H2O2,0.25 mL and illumination time,6 h.Under the same condition,COD decolorizing rates of CWW of dark response and the blank response are 18.5% and 15.9%,respectively.This method has merits such as simple operation,energy conservation,less equipment required,no second pollution and so on.
