摘要
固定污染源烟(粉)尘测试中,烟尘波动、误差大,数据整理存在一定的困难,本文根据实验结果提出了数据修约的范围,并根据监测规范的布点要求,结合实测结果,提出了优化断面布点的设想.在直管段长度满足规范要求的条件下,管道直径小于0.5米时,可选断面上距管壁近的一点作测试点,该点测值可代表断面上平均测值.
In the flyash determination of the fixed pollutant source, the error of datum is big for the fluctuate of flyash, and its data processing is difficult. According to the locating-site request in the monitoring standard as well as the results of practical measurement, the updated range of data was discussed, and the assume of optimum locating site in the section was presented in this paper.
