| 摘 要： | 分析了采用改良氧化沟工艺的城市污水处理厂出水总磷难以达标（1mg／L）的主要原因。ESS偏高、泥龄长、进入厌氧池的混合液硝态氮含量过高是影响除磷效果的主要因素，并提出乐改进措施。

| Abstract: | The main causes why the total phosphorous concentration in the effluent is difficult to reach the standards(1mg/L)in the municipal wastewater treatment plant by modified oxidation ditch are analyzed.It is considered that the high ESS,long SRT,high concentration of nitrate nitrogen in the mixed liquid inflowing into the anaerobic tank are the primary influential factors of the dephosphorization.Meanwhile,a series of improvement measures are given respectively according to each factor. |
