摘要
为实时监测污染物的扩散范围和扩散速度,在煤化工厂周边1 500 m范围内建立了21个监测点,对监测得到的数据采用最小二乘拟合的方法进行分析。分析的结果显示污染物的影响范围大约是1 200 m,污染物扩散速度较快的时间是产生后的20 d内。
In order to real-time monitor the diffusion scope and spread of pollutant, sets up 21 monitoring points in 1 500 m around the coal chemical plant and then using the method of least squares fit to analyze monitoring data. The analysis resuhs show that the influence range of pollutants is about 1 200 m, and the rate of pollutant diffusion is relatively fast within 20 days after production.
