| 摘 要： | 综述了强化生物除磷(Enhanced biological phosphorus removal,EBPR)系统的微生物学和生化特性两方面的最新研究进展.在微生物学方面,归纳了EBPR系统中的主要微生物——聚磷菌、聚糖菌、反硝化聚磷菌的分类及相互之间的竞争和联系.具有聚磷功能的微生物种类繁多,目前普遍认为Accumulibacter是一种典型的聚磷菌,在各种规模的EBPR系统中均不同程度的存在.关于聚磷菌和聚糖菌的联系、反硝化聚磷菌的分类问题存在争论.在生化特性方面,归纳了聚磷菌体内三大聚合物——糖原、聚β-羟基烷酸脂和聚合磷酸盐与聚磷菌代谢功能的关系.聚磷菌厌氧阶段的还原力由糖酵解和有机底物TCA循环共同提供,其比例受种群结构和实验条件影响.糖原根据不同菌株厌氧阶段的降解途径有所不同,但是对细胞都起到调节氧化平衡的作用.聚β-羟基烷酸脂的组成由有机底物决定,丙酸为底物时4种单体均可检测出来.聚磷菌厌氧释磷的能量来自聚磷分解和糖原分解,耗能受环境条件影响.图5表3参37 |

| Abstract: | The microbiological and biochemical characteristics of enhanced biological phosphorus removal(EBPR) process was summarized.With respect to the microbiology,the competition and relationship among the main microbes in the system,including poly-phosphate accumulating organisms(PAOs),glycogen accumulating organisms(GAOs) and denitrified PAOs(DPAOs) were concluded.A wide variety of PAOs were separated from the EBPR system and the Accumulibacter was considered a typical PAO,existing in all kinds of EBPR systems.T... |
