Abstract:

Animal waste management process is major emission sources of C、N related gases. It is of important significance to investigate the technology of controlling and mitigating pollution and greenhouse gas emissions. This paper reviewed the gas (NH3, N2O, CH4, CO2) emission characteristics of different animal waste management system, analyzed and compared the gas mitigation technologies during manure storage, composting, and liquid waste treatment process. It also suggested to carry out studies on various animal waste emission characteristics, to do comparative research between raw slurry and biogas effluent emissions, and to explore the controlling and biological mechanism of gas emission in waste treatment. All these would provide important and valuable references for controlling gas mitigation during animal waste treatment.

Key words: animal waste, gas emission, mitigation technology

摘要：

畜禽废弃物管理过程是重要的碳氮气体排放源，研究其控制和减排技术对控制污染和温室气体排放具有重要意义。综述了国内外畜禽废弃物管理过程中含氮气体NH3、N2O，以及CH4、CO2等含碳气体的排放特征，分析比较了控制固体堆放、固体堆肥、以及液体废弃物管理过程气体排放的技术， 并提出进一步开展各种畜禽废弃物排放特征、原水与沼液气体排放的对比研究，探索废弃物处理过程气体排放控制的机理和生物学机制的建议，对控制畜禽废弃物碳氮气体排放有重要参考价值。
