三相流化床光催化氧化活性红紫X-2R的研究

Study on the photocatalysis degradation of reactive red-violet X-2R in three-phrase fluidized bed photocatalytic reactor

活性红紫X-2R是一种偶氮型活性染料。本文采用P25型TiO2催化剂,在三相流化床光催化反应器中对活性红紫X-2R染料废水进行光催化降解研究。实验结果表明,催化剂TiO2投加量为1.0g.L-1,溶液pH值为中性时,溶液初始浓度越低,空气流量越大,活性红紫X-2R去除效果越好。

Reactive red -violet X -2R is representative of azo reactive dye. This paper studies on the photocatalysis degradation of reactive red - violet X - 2R wastewater in three - phrase fluidized bed photoeatalytic reactor with titania（ P25 ）. The results indicated that the moderate value of the photocatalyst Titania dosage was 1.0g·L^-1,The reactive red -violet X-2R wastewater can be commendably degraded in low initial concentration .high air flow and neutral pH value with the operation of violet light.
