【摘要】 综合考虑生物除磷与脱氮对环境条件的要求,提出了分级式除磷脱氮的工艺模式,旨在将聚磷菌与硝化菌分别控制在两级反应器中优势生长,以解决硝化菌与其他细菌混合生长系统在除磷与脱氮过程中存在的矛盾关系,达到优化除磷脱氮目的。探讨了分级式除磷脱氮的工艺流程、优化除磷脱氮的可行性及研究要点。更多还原

【Abstract】 A separate-stage process model for phosphorus and nitrogen removal is presented based on comprehensive considering the demands of condition. The purposes are to control PAOs (phosphorus accumulating organisms) and nitrifying bacteria optimum growth in two-stage reactor, respectively, to solve the incompatible relationships between phosphorus and nitrogen removal in the mixed growth system of nitrifying bacteria and other bacteria, to gain the effect for optimal phosphorus and nitrogen removal. The authors discuss the technical process flow, the feasibility for optimal phosphorus and nitrogen removal and the research essential on the system.更多还原
