两级SBR生物除磷脱氮工艺效果实验研究
The experimental research on two-stage SBR process for phosphorus and nitrogen removal efficiency
【摘要】 利用SBR的工艺特点,通过合理控制泥龄,将聚磷菌与硝化菌分别控制在2个SBR反应器中优势生长,以解决聚磷菌与硝化菌等混合生长系统在除磷和脱氮过程中的矛盾。实验证明两级SBR工艺系统生物除磷脱氮是可行的。
【Abstract】 This experiment use SBR process,through rational control of SRT,the purposes are to control PAOs and nitrifying bacteria optimum growth in two-stage reactor,respectively,to solve the paradoxical relationships between phosphorus and nitrogen removal in the mixed growth system of nitrifying bacteria and other bacteria.The result shows that two-stage SBR process phosphorus and nitrogen removal simultaneously is feasible.
