- Abstract:
- The effluent quality of Jinbai reclaimed water plant in Guiyang City, with designed treatment capacity of 30 000 m3/d, meets level Ⅰ- A of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) and recharged into Maijia River as replenishment. A hybrid biofilm reactor (HBR) was applied in bio-treatment process, which utilized high volumetric filling ratio of suspended carriers to achieve biofilm treatment and filtration simultaneously. This biofilm technology removed pollutants efficiently and saved plant footprint obviously by omission of secondary settling tank. This paper described the treatment process, structure design and equipment configuration of the plant, and also summarized the operation effect. The effluent pollutants meet the discharge standard since operation. The removal efficiencies of COD, SS, ammonia nitrogen, TN, TP are 89.4%, 92.8%, 96.3%, 48.4%, 90.9%, respectively. The footprint for unit treated wastewater is 0.36 m2/(m3·d-1). The operation cost is 0.56 yuan/m3, which is close to that of conventional activated sludge process with similar capability.
