猪舍有害气体检测与控制方法的研究现状

Research status of the detection and control methods of harmful gases in pig houses

在规模化养猪环境中,会产生大量有害生猪健康的氨气、硫化氢和二氧化碳等气体,一定浓度的有害气体对生猪没有太大影响,当其浓度升高会引起生猪的生产率下降、抵抗力减弱、厌食和疾病等一些严重问题。为此,对猪舍内有害气体浓度进行检测分析十分必要,并采取有效措施将有害气体的浓度维持在适宜范围,为生猪的养殖提供舒适的生长环境。文章简述了猪舍内有害气体的危害及标准,论述了国内外有害气体在猪舍内的检测方法(包括光学法、传感器分析法、气体探测管法等)以及近些年研究现状,并对有害气体控制方法研究现状进行了分析。

In the environment of large - scale pig fanning, a lot of harmful gases that are harmful to the health of pigs can be produced, such as ammonia, hydrogen sulfide and carbon dioxide gas. A certain concentration of harmful gases has little impact on the pigs, but some serious problems can be caused when the concentration of harmful gases are increased, such as the decline in productivity, weakened immunity, anorexia and diseases in pigs. Therefore, it is necessary to detect and analyze the concentrations of hamfful gases, and then the effective measures should be adopted to maintain the concentration of harmful gases to the suitable range for pig breeding to provide a comfortable growing environment. This paper briefly describes the hazards and standards of harmful gases in the pig houses, and discusses the domestic and foreign detection methods of harmful gases in the pig houses, including the methods of optics, sensor analysis, gas detection tube, etc. as well as the research status in recent years, and also analyzes the research status of the control methods of harmful gases.
