The problems of carbon source supply and sludge age control could be effectively solved in the processes by means of " one carbon source for two uses " and " two - sludge system " , meanwhile phosphorus and nitrogen can be removed with less oxygen requirements and sludge production 該工藝以其特有的“一碳兩用”和“雙泥系統(tǒng)” ,有效解決了常規(guī)生物脫氮除磷工藝的碳源供求矛盾和泥齡控制問題,可同時獲得較高的除磷和脫氮效率,并具有所需曝氣量少,剩余污泥排放量低等特點。
