摘要:
研究了实际印染废水的TiO2光催化降解,并与不加催化剂的光降解进行比较.结果表明:采用TiO2为催化剂可以显著加快光催化氧化过程.探讨了pH值,催化剂用量,气流速率及过氧化氢对光催化降解的影响.当催化剂用量为2 g/L,气流速率为0.4 L/min时光催化效率最高.最佳pH值取决于水样的色度和COD.过氧化氢的加入可显著提高废水的光催化脱色率.

Abstract:
Photocatalytic degradation of dying wastewater was carried out with or without TiO2 as catalyst and low-pressure mercury lamp as light source.It is shown that TiO2 could greatly accelerate photooxidation of dying wastewater.The varieties that effect the efficiency of photocatalytic degradation of dying wastewater including pH value,the mount of TiO2,flow rate of air and H2O2 were studied and optimized.
Key words:  TiO2  photocatalytic degradation  dying wastewater
