摘要:
采用光催化耦合膜分离一体化实验装置,分别考察了紫外辐照强度,悬浮二氧化钛浓度,腐殖酸初始溶解性有机碳DOC(Dissolved organic carbon)浓度,pH,添加H2O2对去除腐殖酸HA(Humic acid)效果的研究。结果表明,一定范围内提高紫外灯的辐照强度或TiO2质量浓度,均可加快光催化反应速率; 不同初始质量浓度的腐殖酸,其光催化降解速率没有明显的差别,由于吸附的原因,较低的DOC具有较高的去除率; 不同pH显著影响HA降解效果,低pH有利于提高光催化降解速率及去除效率; 适量添加过氧化氢可以提高HA去除率及其降解速率。
Abstract:
The effect of the removal of DOC in humic acid HA(Humic acid)has been investigated coupling photocatalytic and membrane separation experiment with UV irradiation intensity, initial concentration of titanium dioxide suspension, dissolved organic carbon DOC(Dissolved organic carbon)concentration of humic acid, pH value, addition of H2O2. It could improve the rate of catalytic oxidation with increasing radiation intensity of ultraviolet lamp or the concentration of TiO2 at certain range. The lower DOC of initial concentration of humic acid has a higher removal rate because of adsorption, but the photocatalytic degradation rate has not been significantly improved. The pH value significantly influenced the effect of the degradation of HA, the lower pH value has improved the photocatalytic degradation rate and the overall removal efficiency. It also could improve the removal rate and the rate of degradation of HA by adding appropriate amount of H2O2.
