光催化耦合膜分离去除腐殖酸效果研究
Study on Removal Effect of Humic Acid by Photocatalytic Coupling Membrane Separation
摘要
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.关键词
