| 摘 要： | 因进水BOD浓度偏低，导致氧化沟工艺除磷能力下降。为保证出水达标，通过增大氧化沟缺氧区、减少污泥回流量、增大氧化沟缺氧区＋控制溶解氧等3种方式进行调试并比较，第3种方式最有利于低碳源情况下对TP的去除，去除率在57％～82％，与第1、2种方法相比，不会产生NH3—N去除能力和氧化沟内MLSS浓度下降等副作用。

| Abstract: | Influent with low BOD content leads to the ability of phosphorous removal with oxidation ditch process decreased. After extension of anoxic area, reduction of sludge returning and extension of anoxic area plus dissolved oxygen control are applied and compared, the third is favorable for 57% - 82% TP removal under condition of low carbon, not being free from side-effect of NH3-N removal and MLss content within oxidation ditch dessending. |
