| 摘 要： | 提出了一种TiO2/PbO2复合膜圆形光催化氧化反应器,研究了该反应器对经生化处理后的染料废水进行降解的过程.研究表明:光催化氧化的最佳条件是锌片镀TiO2/PbO2复合膜、pH=8.0、H2O2质量浓度为400 mg/L.并对其他氧化剂对该过程的影响进行了探讨.有机废水通过该反应器进行处理后,其COD降为48.4 mg/L.能使有机污染物全部降解为小分子无机物,废水达到国家一级排放标准.

| Abstract: | A kind of round-shaped reactor of TiO2/PbO2 composited film by photocatalytic oxidation is put forward. The degradation process of the bio-chemically treated dye wastewater by using this reactor has been studied. The results show that the optimal conditions of photocatalytic oxidation are: zinc slice with TiO2 /PbO2 plated composited film, pH =8, H2O2 400 mg/L. The affecting factor of other oxidants on this process are discussed. After the organic wastewater is treated with this reactor, its COD is reduced ... |
