摘要
介绍了光催化氧化法的原理 ,对光催化氧化法处理有机废水的可行性进行了试验 ,探讨了 COD随反应时间的变化规律及催化剂用量、温度、浓度的影响。试验表明 ,光催化氧化可降解象洗涤剂这样难降解的有机物 ,反应 1 2 0 min COD去除率可达 50
As a wastewater treatment technique,the principles of ultraviolet photocatalytic oxidation process was presented.The feasibility of organic wastewater treatment,the change regularity of COD with time and the influences of photocatalyst,temperature and concentration were tested.The results indicated that this process could treat some organic wastewaters,such as detergent wastewater,which were difficult to be degraded,and the COD removal efficiency could reach 50 %.
