规模化畜禽养殖污染气体现场检测方法与仪器研究进展
随着中国畜禽生产的规模化和集约化,畜禽舍内饲养密度增大,产生了许多污染气体。这些污染气体含有大量的氨、硫化物和挥发性有机物等有毒有害成分,不仅影响畜禽的正常生长,而且当这些污染气体扩散到大气中,会对大气环境造成环境污染,严重影响城乡的空气质量,使人类生存环境不断恶化,危害饲养人员及周围居民的身体健康。本文阐述了几种典型污染气体特征,综述了国内外规模化畜禽养殖主要污染气体现场检测方法和分析仪器研究现状,为实现对污染气体进行快速、准确检测,并判定其成分与浓度提供十分必要的依据,也为中国畜禽养殖污染气体检测技术的发展提供一定参考。...

College of Biosystems Engineering and Food Science, Zhejiang University, Hangzhou 310058, China; 2. College of Engineering & Technology, Huazhong Agricultural University, Wuhan 430070, China) With the development of Chinese large-scale and intensive livestock production, the animal stocking density increases, resulting in a lot of pollutant gas emissions. They are not only the important sources of greenhouse gas (GHG) emissions such as carbon dioxide (CO2), methane (CH4) , nitrous oxide (N2O), but also the sources of nitrogen or sulfur organic odors such as hydrogen sulfide (H2S), ammonia (NH3), mercaptan, phenol, paracresol, indole, skatole, which are produced by manure fermentation and decomposition. These gases contain large amounts of toxic and hazardous ingredients. If the concentration of pollution gas is small, the gas can be diluted by diffusion after emitting into the air. If the gas fails to be |
