  A farm in Beitousi Village, Yuci District, Jinzhong City, Shanxi Province, where pigs, cows, and sheep are simultaneously raised.
 
項目背景Background
 
  隨著社會的發(fā)展和養(yǎng)殖業(yè)規(guī)模的擴大,農(nóng)業(yè)源NH3對環(huán)境空氣質(zhì)量的影響越來越大,它們在自然界中占有很大的比重,可促進二次氣溶膠和灰霾的形成,甚至對大氣中O3的產(chǎn)生也有間接影響。
 
  With the development of society and the expansion of the livestock industry, the impact of agricultural NH3 emissions on environmental air quality has been increasing. These emissions have a significant presence in the natural environment and can promote the formation of secondary aerosols and haze, even indirectly affecting the production of O3 in the atmosphere.
 
  項目目標(biāo)Objectives
 
  掌握畜舍NH3排放和擴散規(guī)律,了解NH3對二次氣溶膠形成過程的影響,運用模型準確、全面地評價大氣NH3。
 
  To understand the emission and dispersion patterns of NH3 in livestock sheds, to comprehend the influence of NH3 on the formation of secondary aerosols, and to employ models for accurate and comprehensive assessment of atmospheric NH3.

分析方法Analysis Methods
 
  該項目使用了開路式激光NH3分析儀(HT8700)用于養(yǎng)殖場NH3濃度的在線測量。該分析儀采用車輛移動平臺搭載形式(圖2.3a),它包括Healthy Photon HT8700大氣氨激光開路分析儀、 數(shù)據(jù)采集模塊、GPS 模塊、超聲波三維風(fēng)速儀模塊和實時數(shù)據(jù)處理模塊等(圖2.3b)
 
  This project utilized an open-path laser NH3 analyzer (HT8700) for online measurement of NH3 concentrations in the livestock farm. The analyzer was mounted on a mobile platform (Figure 2.3a) and included the Healthy Photon HT8700 Atmospheric Ammonia Laser Open-Path Analyzer, data acquisition module, GPS module, ultrasonic three-dimensional wind speed module, and real-time data processing module (Figure 2.3b).

結(jié)論Conclusion:
 
  通過國標(biāo)法(納式試劑分光光度法)與開路式激光NH3分析儀(HT8700)對NH3測量結(jié)果進行對比發(fā)現(xiàn)HT8700測的結(jié)果高于國標(biāo)法的NH3濃度值,但在可接受范圍內(nèi),并不影響對于測量養(yǎng)殖場NH3的使用,HT8700為開路式,實時測量,方便靈活,便于捕捉養(yǎng)殖場NH3短期內(nèi)的波動。
 
  A comparison between the results of NH3 measurements obtained by the national standard method (nano-reagent spectrophotometric method) and the open-path laser NH3 analyzer (HT8700) revealed that HT8700 produced NH3 concentration values higher than those of the national standard method. However, these differences were within an acceptable range and did not hinder the use of HT8700 for measuring NH3 in the livestock farm. HT8700 is an open-path, real-time measurement instrument that is convenient and flexible, making it suitable for capturing short-term fluctuations in NH3 levels in the livestock farm.
