摘要
依据气态污染源共同的排放特性及平均排放浓度,排放速率的概念,导出气态污染源监测中常用的三种采样方法:积分法、分部积分法、有限加合近似法。根据分析化学的要求,提出样品采集时间的设计方法。由此得出不同类型排放源的监测时间和采样频率确定方法。
In this paper, with the reference to the velocity of discharge, the average emission concentration and the emission characteristics of the gaseous pollution sources, three sampling methods: integral method, integration by parts and finite summation approximation are derived, which are employed in monitoring of pollution sources. On the basis of analytical chemistry, the design method of the sampling time is provided. Therefore the monitoring method and the sampling frequency of different kinds of emission sources are laid out.
