- Abstract:
- The integrated process of pretreatment, C-UASB, two?stage AO, chemical precipitation and Fenton process is applied to treat swine wastewater in building. The Fenton treatment unit with scale of 360 m3/d is activated under the condition of limited land capacity. The operation results show that the pretreatment, C-UASB, two?stage AO and chemical precipitation processes operate stably under the design conditions. The effluent SS, COD, BOD5, NH3-N, TN and TP are 84.1 mg/L, 126.7 mg/L, 33.7 mg/L, 34.9 mg/L and 4.1 mg/L respectively, meeting the Discharge Standard of Pollutants for Livestock and Poultry Breeding (second draft for comments). After commissioning the Fenton treatment process, the effluent SS, COD, BOD5, NH3-N, TN and TP are 27.4 mg/L, 52.5 mg/L, 15.1 mg/L, 4.9 mg/L, 14.6 mg/L, and 2.1 mg/L respectively, which meets the direct discharge standard in table 3 of local Discharge Standard of Pollutants for Livestock and Poultry Breeding (DB 31/1098-2018) in Shanghai.
