| 摘 要： | 本文以纳米二氧化钛为光催化剂,采用自制的间歇式悬浆体系光催化反应器对活性红K-2BP染料模拟废水进行光催化降解试验,考察废水pH值、初始浓度等因素对反应的影响,在试验条件下,染料模拟废水的COD去除率可达70%以上,反应后废水可生化性提高,其光催化降解反应符合Langmuir-Hinshewood模式,光催化氧化法是处理难降解染料废水的有效方法。

| Abstract: | Reactive Red K-2BP wastewater was Photocatalytic degradaed in TiO_2 suspentions.The results showed that initial pH value had great effects on photocatalytic degradation of wastewaters,the photocatalytic degradation rate of dye-containing wastewaters was higher than 70%.After photocatalytic reaction,the biodegradability of dye-containing wastewaters was increased.The photocatalytic degradation of Reactive Red K-2BP wastewater accorded with Langmuir-Hirnshewood kinetic equation.Photocatalytic degradation was an effective method for treatment of dye-containing wastewaters. |
