中文摘要：

为解决饮用水的嗅味问题，通过实验室配水实验，考察常规处理加浸没式超滤膜一粉末炭组合工艺（OF-PACl对含嗅高藻水的处理效果。研究结果表明：在浸没式超滤膜生物反应器中，粉末活性炭可以吸附超滤膜无法截留的溶解性有机物，并能充分发挥吸附作用和长期的生物降解作用。浸没式超滤膜一粉末炭组合工艺可以强化常规工艺的处理效果，将藻细胞完全截留，对DOC，Uv254和CODmn的去除率在常规处理的基础上分别平均增长19．6％，30．0％和28．3％；经UF-PAC处理后，出水中二甲基异茨醇和土臭素质量浓度均降至10ng／L以下，出水水质得到保证。常规处理和膜生物反应器中的PAC共同延缓膜污染，运行30d跨膜压差仅增加9kPa。

英文摘要：

Hybrid processes of conventional treatment and PAC addition on immersed ultrafiltration membrane was evaluated for the treatment of taste and odor in algal-rich water simulated. The results confirm that in the immersed ultrafiltration membrane bioreactor PAC has sufficient adsorption and long-term biodegradation of dissolved organic materials which cannot be filtrated by ultrafiltration membrane alone. UF-PAC processes could intensify the conventional treatment. Through the advanced treatment of UF-PAC, the algae cells are all removed and the average removal efficiencies of DOC, UV254 and CODMn increase by 19.6%, 30.0% and 28.3% compared with the conventional treatments, respectively. And 2-MIB and geosmin in effluent both fall below the odor threshold, which guarantee the effluent quality. Membrane fouling was mitigated by both conventional treatment and PAC in the membrane bioreactor the transmembrane pressure increases by only 9 kPa in 30 d.
