| Abstract: | According to the reconstruction case in the town, classing function zone and improving equipment on oxidation channel. At the same time enforcing the DO concentration of aerobic zone, while decreasing the DO concentration of anoxic zone; meantime,cementing the capacity of oxidation channel to extend HRT and SRT. The results show that the key output indicators of the system stably achieve GB18918-2002 first-degree emission standards. |
