冬季猪场污水处理设施温室气体排放测试

Greenhouse gas emission from wastewater treatment facilities on swine farms in winter

摘要: 为研究畜禽废弃物处理过程中温室气体泄漏与排放状况，该文利用静态箱对北京市北郎中猪场的污水处理单元进行了温室气体泄漏与排放测试。测试结果表明：厌氧消化罐泄漏造成的温室气体通量为5823.19 mg·m^-2·h^-1 CO₂当量，一、二级氧化塘其CO₂当量的温室气体通量分别为607.75、8.61mg·m^-2·h^-1；由于污水以厌氧处理为主，各处理单元冬季的氧化亚氮排放很低，几乎可以忽略不计。

Abstract: Static chambers were used to investigate greenhouse gas (GHG) leakage and emissions from different treatment units of the wastewater treatment facilities on swine farms in winter. Results showed that leakage flux of GHG from anaerobic tank was 5823.19 mg·m^-2·h^-1 CO₂ equivalent， and the GHG emission fluxes from the primary and secondary aerobic ponds were 607.75、8.61mg·m^-2·h^-1 CO₂ equivalent， respectively.Wastewater was mainly treated via anaerobic processing， therefore， N₂O emission was extremely low and could be neglected.
