　　同时饲养猪、牛、羊的某养殖场
 

　　A farm in Beitousi Village, Yuci District, Jinzhong City, Shanxi Province, where pigs, cows, and sheep are simultaneously raised.
 

项目背景Background

 

　　随着社会的发展和养殖业规模的扩大，农业源NH3对环境空气质量的影响越来越大，它们在自然界中占有很大的比重，可促进二次气溶胶和灰霾的形成，甚至对大气中O3的产生也有间接影响。
 

　　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.
 

　　项目目标Objectives

 

　　掌握畜舍NH3排放和扩散规律，了解NH3对二次气溶胶形成过程的影响，运用模型准确、全面地评价大气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

 

　　该项目使用了开路式激光NH3分析仪(HT8700)用于养殖场NH3浓度的在线测量。该分析仪采用车辆移动平台搭载形式(图2.3a)，它包括Healthy Photon HT8700大气氨激光开路分析仪、 数据采集模块、GPS 模块、超声波三维风速仪模块和实时数据处理模块等(图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).
 

　　项目采用纳式试剂分光光度法(HJ533-2009)与开路式激光NH3分析仪测量精度对比实验。
 

　　The project conducted a comparative experiment on measurement accuracy between the nano-reagent spectrophotometric method (HJ533-2009) and the open-path laser NH3 analyzer.
 

 

结论Conclusion:

 

　　通过国标法(纳式试剂分光光度法)与开路式激光NH3分析仪(HT8700)对NH3测量结果进行对比发现HT8700测的结果高于国标法的NH3浓度值，但在可接受范围内，并不影响对于测量养殖场NH3的使用，HT8700为开路式，实时测量，方便灵活，便于捕捉养殖场NH3短期内的波动。
 

　　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.
