摘要：

将自生动态膜技术应用到厌氧废水处理领域,常温下处理低浓度生活污水。考察了厌氧自生动态膜生物反应器常温下处理模拟城市生活污水的可行性及稳定性;探讨了自生动态膜的形成过程和代谢及截留能力;同时对膜面物质进行了分析。结果表明:厌氧自生动态膜工艺对模拟城市生活污水COD平均去除率达89.5％;自生动态膜除具有良好的截留能力以外,也具有一定的生物代谢活性,可去除7％的COD;粒径分析表明粒径为32μm～62μm的污泥粒子,更容易附着在无纺布表面形成污泥层,构成自生动态膜的主体。红外分析表明自生动态膜污泥层中存在多糖、蛋白质及腐植酸等成分。

Abstract:

A self-forming dynamic membrane was introduced into anaerobic wastewater treatment for low strength municipal wastewater treatment. The feasibility and stability of the anaerobic self-forming dynamic membrane bioreactor (ASFDMBR) were investigated. The metabolic and interception ability and components of the selfforming dynamic membrane (SFDM) were also studied. The results showed that the ASFDMBR had good COD removal efficiency as high as 89.5％. SFDM had considerable metabolic ability with a COD removal efficiency of 7％, as well as good interception capacity. Sludge with a particle size range of 32μm～62μm was the major part of the SFDM. FTIR revealed that protein, polysaccharide and humic acid were the components of the SFDM.

Key words: anaerobic membrane bioreactor; self-forming dynamic membrane; domestic wastewater; EPS; sludge layer analysis
