摘要
采用预处理/C-UASB/两级AO/化学沉淀/Fenton工艺处理楼房养猪废水,其中Fenton处理单元在土地消纳能力有限的情况下启用,处理规模为360 m^(3)/d。运行结果表明,在设计条件下,预处理/C-UASB/两级AO/化学沉淀工艺运行稳定,出水SS为84.1 mg/L,COD为126.7 mg/L,BOD_(5)为33.7 mg/L,NH_(3)-N为16.3 mg/L,TN为34.9 mg/L,TP为4.1 mg/L,达到《畜禽养殖业污染物排放标准》(二次征求意见稿)。Fenton处理工艺调试启用后,出水SS为27.4 mg/L,COD为52.5 mg/L,BOD_(5)为15.1 mg/L,NH_(3)-N为4.9 mg/L,TN为14.6 mg/L,TP为2.1 mg/L,达到上海市《畜禽养殖业污染物排放标准》(DB 31/1098—2018)表3中的直接排放标准。
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 m^(3)/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,BOD_(5),NH_(3)-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,BOD_(5),NH_(3)-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.
