固定污染源废气中一氧化碳浓度测量的不确定度分析

Stationary Source Emission-determination of Carbon Monoxide-fixed Potential Uncertainty Analysis

近年监测中,燃生物质成型燃料锅炉的大气污染物一氧化碳排放浓度超标情况较多,而很大部分位于标准限值附近,文章主要采用定电位电解法测定固定污染源废气中一氧化碳,分析不确定度来源,利用配气系统引入含氧量情况下进行不确定度试验,得出测定浓度范围的不确定度值,更科学、准确的给出监测结果,以期为环境监督监测及环境管理提供依据。

Monitoring in recent years, the burning straw briquette fuel boiler carbon monoxide emissions of air pollutants concentration exceeds bid is more, but a large part near the standard limit, this paper mainly USES the constant potential electrolysis method determination of carbon monoxide in stationary sources waste gas, analyzed the uncertainty sources, with the introduction of oxygen gas distribution system test, the uncertainty of determination of the concentration range value uncertainty, more scientific and accurate monitoring results, in order to provide the basis for environmental supervision and monitoring and environmental management.
