摘要: 为解决污水处理厂及生活垃圾焚烧发电厂等行业温室气体排放的监测难题,打破监测设备性能指标的国外依赖性,建立针对N2O与CH4监测设备的量值溯源体系,本研究通过手工监测和便携设备测量2种方式,分析N2O和CH4排放质量浓度监测结果的差异。结果显示,对于污水处理厂典型场景下的3个不同点位,手工监测和便携设备测量的N2O平均质量浓度差分别为8.66、12.20、0.75 mg/m3,CH4平均质量浓度差分别为45.74、64.30、214.82 mg/m3,2种测量结果差异性较大。在电厂典型场景下,手工监测与在线监测数据差异较小,与便携设备测量结果差异较大。造成差异的主要原因为便携设备易受温湿度及气体之间的相互干扰。后续应加强便携设备在水汽、高温、高湿及多种气体共存方面的研究,提高便携设备测试精准度。总的来说,手工监测更为精准可靠。
