摘要
介绍了传统生物除磷脱氮和反硝化除磷的机理,比较了几个有代表性的传统除磷脱氮工艺和反硝化除磷工艺。通过分析认为反硝化除磷菌(DPB)能够以硝态氮为电子受体,从而大大节省耗氧量,缓解常规工艺对外加碳源的需求。如何在不增加工艺流程复杂性的同时,在工艺中充分富集DPB是反硝化除磷的关键。
The mechanism of traditional biological nutrient removal and denitrifying dephosphatation were introduced, meanwhile, several typical traditional nutrient removal processes and denitrifying dephosphatation processes were compared. The analysis indicated that, DPB could use nitrate-nitrogen as electron acceptor, which greatly saved the consumption of oxygen and reduced the demand of conventional process for external carbon source. The key point of denitrifying dephosphatation was how to make full use of DPB without complicate the process flow.
