摘要
总结了污水反硝化除磷的机理、微生物、工艺以及影响因素等,重点分析了基于反硝化除磷原理研发的各种工艺的流程和特点,以及反硝化除磷性能的影响因素如碳源、电子受体、水力停留时间、温度和其他环境参数等。指出双污泥工艺的反硝化除磷率要高于单污泥工艺,但是双污泥工艺略为复杂,限制了其实际工程应用。如何提高单污泥工艺反硝化除磷率和简化双污泥工艺流程是未来工艺研发的重点方向,同时做好工艺影响参数优化,提高反硝化除磷技术在污水处理中的应用。
The mechanism,microorganisms,process and influencing factors of wastewater denitrifying phosphorus removal was summarized,and the process scheme and characteristics based on denitrifying phosphorus removal research,as well as influencing factors such as carbon sources,electronic acceptors,hydraulic retention time,temperature and other environmental parameters were discussed.It was indicated that the denitrifying phosphorus removal efficiency of double sludge process was higher than that of single sludge process,but the double sludge process was slightly complex,which limits its practical application.How to improve the denitrifying phosphorus removal efficiency in single sludge process and simplify the double sludge process are the key research in future,at the same time,process parameters optimization would be enhanced and improve the application of denitrifying phosphorus removal technology in wastewater treatment.
