- Abstract:
- Considering the expansion of the wastewater treatment plant, extension of the pipeline network and ecological replenishment of the river, the concept of decentralized sewage treatment was adopted. A river ecological replenishment station (RERS) was established in the middle section of the main pipeline of the city so that its effluent could be used for river replenishing nearby. Based on the concepts of intensiveness and buried design, the process including A2O and MBBR, rectangular settling tanks, coagulation settlement tank, rotary filter and active carbon filtration was selected, with the design capacity of 6 000 m3/d. The average effluent COD, BOD5, SS, NH3-N, TN, TP were 20.5 mg/L, 3.95 mg/L, 5.7 mg/L, 0.46 mg/L, 12.1 mg/L, 0.16 mg/L, respectively, which could basically meet level Ⅳ of Environmental Quality Standards for Surface Water(GB 3838-2002). The implementation of this project provides a new idea and design reference for the construction of urban wastewater treatment facilities and comprehensive treatment of regional water environment.
