摘要
长光程空气质量自动监测仪是用来监测大气中各种污染物含量的专用仪器,采用国家环保部认可和美国环境保护署(USEPA)推荐的方法,利用光学差分吸收光谱技术研制而成,差分吸收光谱(DOAS,Differential Optical Absorption Spectroscopy)技术国外已广泛用于环境监测,国内也已形成产业。我站引入国产长光程系统(安徽铜陵)开展污染气体(SO2、NO2)24小时连续监测。本文就我站在使用国产长光程大气监测系统过程中出现的一些常见问题进行剖析,以供参考。
There are composed of lots of parts and complicated construction in the long - path air automatic monitoring system, the running substations is supervised and controlled by master station through the on - line way, therefore it is difficult to diagnose and exclude break downs the system caused. This paper is to help the operators deepen their comprehension for the system and improve the skill in excluding the abnormal data through diagnosing and analyzing the abnormal data from the master station.
