| 中文摘要 |
| 采用日光和中压汞灯为光源,分别在充空气、O3、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历程。 |
| 英文摘要 |
| The photochemical oxidation treatment for selected organic wastewaters which were hard to degrade and were performed by adding H2O2 or some semiconductor powder and bubbling of O2 or O3 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. |
