光催化技术处理活性紫染料废水

Photocatalysis technology for reactive-purple dye waste water treatment

在光催化处理活性紫废液的实验研究中,首先以新建固相脱色率为指标得出脱色的适宜操作条件,即TiO2含量1 g/L、废液初始浓度60 mg/L、设备进气量0.8 m3/h、灯功率105 W;然后在适宜操作条件下进行有机物降解的实验与分析,试图通过多指标的联合使用对有机物降解过程给出新解释。

In the experiment of photocatalysis treatment for reactive-purple dye waste water, the index of decolorization rate of solid-phase was first used to replace the conventional decolorization rate of liquid-phase, and the optimum operation conditions of decolorization were as follows. TiO2 content lg/L, waste water initial concentration 60 mg/L, air input 0.8 m^3/h, lamp power 105 W. In experimental analysis Of organic substance degradation, a new explanation about organic substance degradation was given by using several indices in combination.
