摘要
环境空气质量自动监测系统是以自动监测仪器为核心的自动"测-控"系统。从原理、结构、系统构成、性能指标、日常维护、校准等多方面对DOAS大气监测系统与传统点式采样设备在实际工作运行中的情况进行对比分析。DOAS系统可检测相当数量的气态有机物,同时其先进的监测技术可提供对一些非标准污染物气体的监测,如对BTX(苯系物),Formaldehyde(甲醛),HN02,NO3等的监测。在燕山地区有针对性的布设DOAS系统的大气监测站点,可以更好的对该地区的特征污染物进行监控,为企业的发展和环境保护提供数据支持。
Automatic monitoring system for ambient air quality is an automatic ' inspecting-control' system with automated monitoring equipment as the key part.This article makes a comparative analysis on DOAS atmospheric monitoring system and traditional point sampling equipment in practical operation from the aspects of principle,configuration,system structure,performance index,routine maintenance and calibration.DOAS system can detect a considerable number of gaseous organic compounds.Meanwhile,its advanced monitoring technology provides monitoring of some non-standard pollutant gases,such as BTX(benzene),formaldehyde,HN02,NO3,etc..Yanshan area can be well monitored by setting up target air monitoring site with DOAS system in necessary places,which can also provide data support for the development of the enterprises and environmental protection for the companies.
