    摘要:

    NH3排放系數(shù)是對規(guī)?；B(yǎng)殖場NH3排放量估算,、NH3減排方法與技術(shù)應(yīng)用效 果評估的有效方法之一,。通過在模擬實際生產(chǎn)動物人工氣候室對3種不同地面結(jié)構(gòu)的育肥豬 舍NH3排放相關(guān)數(shù)據(jù)的連續(xù)在線檢測,，研究了不同地面類型豬舍內(nèi)NH3排放與主要影響因 子的相關(guān)性及其排放系數(shù),。研究得出半縫隙地面豬舍,、實心地面豬舍,、生物發(fā)酵床豬舍內(nèi)NH 3排放系數(shù)分別為：(947±709)、(1123±423),、(427±209)g/(d pig),。

    Abstract:

    Ammonia (NH3) and other air pollution emissions from concentrated animal fee ding operations (CAFOs) are becoming more and more serious with the rapid develo pment of livestock and poultry production in recent years. The ammonia emission factor is one of the effective methods for estimating ammonia emissions from CAF Os and evaluating of emission reduction technologies. A continual monitoring sys tem of the NH3 concentration and environmental parameters is used in this rese arch, and the ammonia emission factors and impact factors of the three types of floor systems in the pig buildings are studied. Mean daily emissions per pig fat tened on the semislatted floor system, concrete floor system, and deeplitter system are (947±709), (1123±423), (427±209)g/(d?pig), respectively.
