| 摘 要： | 采用饱和活性炭作为臭氧氧化催化剂,对染料废水生化出水进行深度处理.以废水COD、DOC去除率为指标,考察饱和活性炭对臭氧的催化效果.使用6种不同的活性炭作为催化剂(编号1#~6#),并将6#活性炭采用KMnO4、NaOH、ZnCl2、H2SO4、H3PO4进行表面处理,在活性炭的孔体积、酸碱基团等表面性质测定的基础上,探讨活性炭性质与催化臭氧化效率的关系.结果显示,活性炭催化效果与大孔体积密切相关;另一方面,使用微孔膜片减小臭氧气泡尺寸,增大臭氧的传质面积,提高臭氧利用率,可以改善臭氧/活性炭催化氧化处理效果.

| Abstract: | Saturated activated carbon catalytic ozonation process was employed for tertiary purification of biologically-treated effluent of dye-making wastewater. COD and DOC removal efficiencies were determined to investigate the catalytic performance of activated carbon. Surface properties of activated carbons (No. 1#~6#) including volume of pores, acid groups and basic groups were measured and the relationship between the surface characteristics of activated carbon and catalytic performance was examined. The experimental results showed that the catalytic efficacy of activated carbon was mainly depended on the macropore volume. The catalytic efficiency of activated carbon 6# modified with chemicals including KMnO4, NaOH, ZnCl2, H2SO4, and H3PO4 varied significantly and related to the macropore volume. It was also found that the installation of the microporous membrane at the reactor bottom, which decreased the size of ozone bubbles and increased the specific interfacial area of ozone bubbles, improved the utilization efficiency of ozone and strengthened the ozone/activated carbon oxidation process significantly. |
