| 摘 要： | 四川新都金海污水处理厂采用改良型DE氧化沟工艺,即在DE型氧化沟前加设缺氧池和厌氧池以强化除磷。为防止污泥膨胀,设立了一个生物选择区,而且采用两点进水法(20%的污水进入缺氧区,80%的污水进入生物选择区)。运行结果显示,该工艺运行效果良好,出水水质达到一级排放标准。

| Abstract: | The modified DE oxidation ditch was adopted in Xindu Jinhai Wastewater Treatment Plant,that is,an anoxic tank and an anaerobic tank were set up in front of DE oxidation ditch for enhancing the phosphorus removal.In order to avoid sludge bulking,a biological selection area was established and two points feeding was adopted with 20% wastewater into anoxic area and 80% wastewater into the biological selection area.The operation result shows that the process operates efficiently and the effluent quality reaches the primary discharge standard. |
