摘要

摘要在1.2 m3堆肥反应器中,在好氧条件下,用木泥炭作为添加剂与猪粪堆肥77 天,以估计对堆肥成熟度和气体排放(NH3、N2O和CH4)的影响。猪粪也用玉米秸秆堆肥(传统方法)作为对照处理。结果表明,玉米秸秆和木质泥炭堆肥均达到了要求的成熟度标准。与玉米秸秆改良处理相比,用木质泥炭作为膨松剂堆肥可减少36%的NH3排放。尽管添加木质泥炭增加了CH4排放,但N2O排放量显著减少,导致温室气体总排放量略有下降。更重要的是,木质泥炭可以减少总碳和总氮的损失,提高堆肥的肥料质量。

Effect of Woody Peat as an Additive on Maturity and Gaseous Emissions During Pig Manure Composting
Abstract Woody peat was used as an additive to compost with pig manure in 1.2 m3 composting reactors under aerobic conditions for a 77 days period to estimate the effect on the compost maturity and gaseous emissions (NH3, N2O, and CH4). Pig manure was also composted with cornstalks (the traditional method) as a control treatment. The results showed that both cornstalks and woody peat composts reached the required maturity standard. Composting with woody peat as a bulking agent was found to reduced NH3 emissions by 36% than the cornstalks amended treatment. Although CH4 emission increased by adding woody peat, N2O emission was considerably reduced, resulting in a slight decrease in total greenhouse gas emissions. More importantly, woody peat could reduce the losses of total carbon and total nitrogen, improve the compost quality as fertilizer.
