- Abstract:
- The total scale of a municipal wastewater treatment plant in Zhejiang Province is 8.0 ×104 m3/d, which is divided into three phases, of which the first and the second phases are 4.0×104 m3/d. The main process is modified SBR process, and the effluent quality was required to meet the first level B criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). However, the discharge standard is required to upgrade to the local standard of Zhejiang Province Discharge Standard of Major Water Pollutants for Municipal Wastewater Treatment Plant (DB 33/2169-2018). Owing to the limited footprint and short construction term, the combined process of A/A/O, MBBR and DBDF was finally adopted in the upgrading project. The wastewater treatment plant runs stably after the reconstruction, and all indexes in the effluent reach the design standards.
