    摘要:

    氧化沟工艺具有操作简单、运行费用低和出水水质好等优点,在污水处理领域应用广泛。然而,氧化沟工艺中硝化菌、反硝化菌和聚磷菌生长速率不协调,难以实现同步高效脱氮除磷的效果。因此,本文综述了氧化沟脱氮除磷影响因素及发展趋势。详细分析了温度、DO、pH、SRT等因素对脱氮除磷效果的影响,为氧化沟工艺脱氮除磷效果最优化操作提供理论依据。

    Abstract:

    The oxidation ditch processes on waste water treatment possess a large number of advantages, such as easy operation, low cost, and excellent water quality in effluent. However, the growth rate of nitrifying bacteria, denitrifying bacteria and phosphorus-accumulating bacteria in the oxidation ditch process is not well coordinated, so it is difficult to achieve the effect of simultaneous and efficient nitrogen and phosphorus removal. In this paper, the factors influencing nitrogen removal and phosphorus removal from oxidation ditch are summarized. The effects of temperature, DO, pH, SRT and other factors on nitrogen and phosphorus removal were fully analyzed, which providing theoretical basis for optimization of nitrogen and phosphorus removal efficiency in operation through oxidation ditch process.
