废水反硝化除磷技术应用研究进展

废水的反硝化除磷技术作为生物除磷的一个新思路，因其能够解决废水处理工艺运行中碳源不足、污泥产量大和好氧阶段曝气能耗大等问题，受到环境保护领域的关注。文章对反硝化除磷的机理、影响因素、现有工艺及研究现状作了综述，并对反硝化除磷技术未来发展作了展望。认为今后研究重点应集中在以下几个方面：①对DPBs有更全面的认识，富集和筛选更多高效的DPBs菌株；②在理论研究的基础上开发更多的反硝化除磷工艺，并将其应用于工程实践。

Application and Research Progress of Wastewater Denitrifying Phosphorus Removal Technology

As a new way to achieve waste water biologycal phosphorus removal, denitrifying phosphorus removal technology can resolve problems such as oganic deficiency, large production of sludge and big energy consumption. It gets much attention from environmental protection domain. The mechanisms, effect factors, processes and research status of denitrifying phosphorus removal were reviewed in the paper, and future progress of denitrifying phosphorus removal were also discussed. Future study should be focused on as follows： First, fully understand the knowledge about DPBs, and find more efficient DPBs; Second, more denitrifying phosphorus removal technology should be employed and used in projects on the base of theory studies.
