硝酸盐与亚硝酸盐对反硝化除磷过程的影响

反硝化除磷能够实现以相同的基质同时脱氮和除磷,具有节约碳源和曝气量的优点。讨论了硝酸盐在厌氧段对反硝化释磷过程和在缺氧段对反硝化吸磷过程的几个影响因素,分析了亚硝酸盐对反硝化聚磷菌的抑制作用与作为电子受体参与反硝化聚磷的条件,并比较了不同电子受体的反硝化除磷效果,为反硝化除磷过程的试验研究和实际应用提供了参考和依据。

The Influences of Nitrate and Nitrite for Denitrifying Phosphorus Removal

In the denitrifying phosphorus removal process,simultaneous removal of nitrogen and phosphorus can be achieved by using the same substrate and has the virtues of saving carbon source and aeration rate.In order to provide reference and basis for experimental research and practical application,the paper had discussed the factors of nitrate in the course of denitrifying phosphorus removal in the anaerobic zone and denitrifying phosphorus absorption in the hypoxia zone,analysed the inhibting effects of nitrite on DPB and the conditions when use nitrite as electron acceptors,compared the phosphorus removal effect when use different electron acceptors.
