Volatile Gas Emissions from Different Types of Animal Manure During Aerobic Fermentation Process
摘要
Abstract
Understanding volatile gases emitted from different types of animal manure is critical for effectively controlling them during aero-bic fermentation of livestock and poultry manure. An experiment with pig manure, chicken manure and cow dung was conducted to examine volatile organic compounds(VOCs), NH3, and H2S produced during aerobic fermentation. The emissions of volatile gases occurred mainly at the earlier stage of aerobic fermentation. Different livestock and poultry manure produced different VOCs. The pig manure produced 9, the cow dung 4, and the chicken manure 8 kinds of VOCs. However, the major compounds of the VOCs included dimethyl disulfide, dimethyl trisulfide and dimethyl sulfide, indicating the importance of monitoring and managing these three VOCs. The emissions of H2S were the high-est from the pig manure, but the lowest from the cow dung. The emissions of NH3 lasted the longest time from the chicken manure, whereas the shortest from the cow dung.关键词
