- Abstract:
- After the upgrading and expansion of a WWTP in Jiangmen, the total design capacity increased from 20×104 m3/d to 22×104 m3/d. The effluent quality has been upgraded from the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) to the stricter of the first level A criteria in GB 18918-2002 and the first level criteria of the second stage specified in Discharge Limits of Water Pollutant (DB 44/26-2001) in Guangdong Province. This paper elaborates the design and operation effect of the AAO-MBBR, cloth media filter, and denitrification deep bed filter (DDBF) process, which could provide reference to the upgrading of WWTP with limited land use conditions.
