摘要
用微滤膜/光催化反应器处理含腐殖酸的合成污水,讨论了腐殖酸的去除效率和膜污染的情况.在间歇操作的过程中,光催化反应使溶液中腐殖酸的浓度(分别以溶液在254nm处的吸收值UV254和总有机碳含量TOC来表示)不断升高,经过一段时间的反应后再逐渐降低,4h时腐殖酸的UV254和TOC的去除效率分别为99%和89%.在操作全过程中无明显的膜污染.
Synthetic sewage contg, humic acids （HAs） was treated with micro-filter membrane/photo-catalytic hybrid reactor. The HAs removal efficiency and membrane fouling were discussed. In the batch operations, photo-catalysis increased continuously the HAs concns, in the solns. （as UV254. i.e., absorption at 254 nm in solns, and TOC, i.e., total org. carbon）, and decreased gradually after the reaction for a time. The HAs removal efficiencies UV254 and TOC were 99% and 89%, resp., in 4 h. No obvious membrane fouling was found in the total operation course.
