【摘要】 试验对不同电子受体对生物除磷的影响和各自优势进行了研究。在3个SBR反应器中,分别考察了以NO3--N和NO2--N为电子受体的反硝化除磷现象,以及传统以O2为电子受体的生物聚磷现象。试验结果表明传统生物聚磷在吸磷效果上要优于两种反硝化除磷方式,但后两者的耗氧量和碳源需求减少。以NO3--N为电子受体的反硝化除磷在除磷效果上要优于以NO2--N为电子受体的反硝化除磷,但脱氮效果差。更多还原

【Abstract】 The effects of different electron acceptors on biological dephosphatation and their respective advan-tages were studied through the test.In the three SBR reactors,the phenomenons of denitrifying dephosphatation with NO3——N and NO2——N as electron acceptors and the traditional biological phosphorus accumulation with O2 as electron acceptor were investigated respectively.The results of the test showed that,the removal effect of phosphorus with the traditional biological phosphorus accumulation process was better than with the two denitrifying dephosphatation processes,however,the latter two required less oxygen and carbon source.The denitrifying dephosphatation with NO3——N as electron acceptor had better effect on phosphorus removal than that with NO2——N as electron acceptor,but the effect of it on nitrogen removal was bad.更多还原
