摘要：

采用分子生物学手段,通过构建16S rDNA基因文库,对新型剩余污泥减量化处理系统——序批式生物砾间接触氧化反应器中细菌多样性进行了系统发育分析,并讨论了多种细菌共存对剩余污泥减量化的贡献.共有72个克隆子用于细菌系统发育分析.结果表明:填料表面附着细菌与孔隙内细菌由变型菌属、噬纤维菌-屈挠杆菌-拟杆菌组(CFB)、硝化杆菌科、低G+C革兰氏阳性细菌、高G+C革兰氏阳性细菌、疣微菌科和绿菌科等七大类细菌组成.其中,优势菌群分别是以兼具呼吸/发酵代谢方式的β变形菌纲(分别占生物膜和内泥中克隆子总量的18%和35%)和δ变形菌纲,以及以呼吸/发酵为主要代谢方式的CFB(分别占克隆子总量的24%和23%).多种细菌对剩余污泥减量化的主要功能可归纳为能量解偶联、共代谢作用、生物溶胞作用和慢性生长种群的影响.
