- Abstract:
- The design capacity of the first-stage project of Binhu WWTP in Wujin District, Jiangsu Province is 5×104 m3/d and the design effluent quality should meet Discharge Standard of Main Water Pollutants for Municipal Wastewater Treatment Plant & Key Industries of Taihu Area (DB 32/1072-2018). The multi-mode A2/O+MBR process was adopted, and the final effluent was disinfected by sodium hypochlorite. The effluent quality was better than the discharge standard by using multi-mode A2/O, intelligent gas tracking system, multi-stage sludge reflux, magnetic levitation blower, closed aeration sedimentation tank and wastewater reuse with 0.66 m2/（m3·d-1） land use index of the WWTP， and 0.41 kW·h/m3 power consumption of the WWTP, which not only saves numerous construction land, but also effectively reduces the operation cost of MBR process.
