摘　　要：对各种生物选择器及其作用机理进行了研究和分析 ,指出好氧选择器是利用丝状菌和菌胶团细菌在不同的环境条件下不同的反应动力学参数来工作的 ;而缺氧、厌氧选择器是利用反硝化细菌和聚磷菌在不同的环境化学条件下独特的代谢功能来工作的。另外 ,缺氧、厌氧选择器同除磷脱氮所设置的缺氧池和厌氧池虽然在机理上相同 ,但在目的和结果上具有根本的不同 。The structures and working mechanisms of various biological selectors (BS) are discussed and indicate that the aerobic BS is working on the kinematics of filamentous and zooglea colonies in different conditions and the anaerobic or anoxia BS is working on the particular metabolisms of denitrifying bacteria and poly-phosphorus bacteria in different conditions. Although the later has similar working mechanism with the anaerobic or anoxia tank for P and N removals, but otherwise, they are quit different in working targets and results so in design and operation different structures and parameters have to be applied.
