低浓度生活污水处理一直都是水处理的难点,其有机负荷低,污水处理站运行稳定后活性污泥活性较差,处理后出水难以达到现行环保要求水平。本次实验,就外加碳源对扬州市某污水站低浓度生活污水的处理进行了研究；当葡萄糖投加量≥60 mg·L-1,污水生化处理效果较好,出水可达到《城镇污水处理厂污染物排放标准》(GB8978-2002)中一级A标准；冬季气温低于5℃时,随着投加葡萄糖量的增加,处理效果不够理想。

Low concentration domestic wastewater treatment has difficulty in water treatment, its organic loading is low, and activity of activated sludge is poorer after wastewater treatment station running stability, treated water is difficult to meet the current requirements of environmental protection. In this experiment, external carbon source for the handling of low concentration domestic wastewater was studied by a wastewater station in Yangzhou city. When the additive amount of glucose was 60 mg·L-1 , wastewater biochemical treatment effect was good, the water can reach Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant ( GB8978-2002 ) including a highest standards. When winter temperature was lower than 5 ℃, with the increase of additive amount of glucose, treatment effect was not ideal.
