膜-生物反应器中污泥膨胀对生物相及微生物多样性影响

Microbe diversity and non-vertebrate of active sludge bulking in membrane bioreactor

针对丝状细菌引起污泥膨胀并对系统运行造成影响的现象,采用处理生活污水的MBR工艺连续流小试运行方式,就丝状菌污泥膨胀对MBR系统的影响进行跟踪考察.对反应器内的生物相监测是研究其处理机理的重要内容,结合生物学、分子生物学分析方法,对系统活性污泥混合液中的微生物多样性及无脊椎动物进行了连续跟踪监测.结果表明,系统内随丝状菌污泥膨胀加剧,微生物多样性降低,微型动物优势种群及其数量随环境变化而波动,呈现一定的规律性.

Membrane bioreactor （MBR） is a new kind of the monitor of diversity of bacterium and non-vertebrate in pal sewage of lab test by traditional and modern molecule decreasing and dominant microbiota population change in technology in waste water treatment. This article is process of sludge bulking biology technology. We rule. in MBR that treat munici- found the biology diversity
