| 摘 要： | 采用日光和中压汞灯为光源，分别在充空气、加入Ｈ２Ｏ２或ＴｉＯ２等半导体催化剂条件下，对几种难降解的有机废水进行了光化学处理研究。结果表明：石化和焦化废水中挥发酚，油和ＣＯＤ的去除率分别为８６．３％－１００％，３９．８％－９７．８％，２６．４％－６０％，几种偶氮染料水溶液的脱色率、ＣＯＤ去除率分别为８０．０％－１００％，４８．０％－７５．０％，还测定了苯酚的降解产物，讨论了影响光解的要素和苯酚的降解

| Abstract: | The photochemical oxidation treatment for selected organic wastewaters which were hard to degrade and were performed by adding H 2O 2 or some semiconductor powder and bubbling of O 2 or O 3 under sunlight or a middle pressure mercury lamp.The results showed that the removal rates of COD,oil and volatile phonols were 26.4%-60%,39.8%-97.8% and 86 3%-100% respectively for the wastewaters of oil refinery and coking industry;the removal rates of COD and decoloration rates were 48%-75%,80%-100% for selected azo dye aqueous solutions.The photodegradation products of phenol were also determined. |
