- Abstract:
- The first-phase project need to be upgraded, and the combined process of modified AAO tanks, secondary clarifier, high-efficiency sedimentation tank, precision filter, and joint disinfection was applied to the second-phase extension project of a WWTP in Hunan to strengthen nitrogen and phosphorous removal. The total capability after extension was 40 000 m3/d. The effluent quality was steadily upgraded from the first level B to the level A criteria of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), and the effluent COD met the second level criteria of Discharge Standard of Major Pollutants for Municipal Wastewater Treatment Plant(DB 43/T 1546-2018).
