- Abstract:
- The urban sewage containing industrial wastewater in the northwest region is treated by a combined process including composite primary sedimentation tank, improved Bardenpho process, high-density tank, and V-type sand filter. The composite primary sedimentation tank integrates both flat-flow and inclined tube sedimentation tanks. The flow rate ratio of the improved Bardenpho process is 2.0∶4.0∶4.0 for the pre-anoxic section, anaerobic section, and anoxic Ⅰ section. To accommodate low-temperature conditions, structures are designed to be either underground， semi-underground or located indoors. When influent COD, TN, NH4+-N and TP concentrations range from 65.07-535.17 mg/L，17.12-53.56 mg/L，13.09-46.42 mg/L， 1.57-7.18 mg/L, respectively, the effluent concentration is superior to the level A criteria in Discharge Standards of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Portions of this effluent can be utilized for long-term ecological water replenishment as well as garden irrigation. This treatment process demonstrates effective operation under winter’s low-temperature conditions with an operating cost of only about 2.46 yuan/m3.
