Abstract
A methodology for estimating, under field conditions, the microbial die-away constant (lambda) is presented. This constant may be used in predicting the aerosolized pathogenic microorganism concentrations downwind from a wastewater spray or aeration site by means of modified atmospheric diffusion equations. The mean lambda of Escherichia coli for very early morning runs was 8.8 X 10(-3)s-1, and that for afternoon runs was 6.6 X 10(-2)s-1.
摘要
本文提出了一种在现场条件下估算微生物衰减常数（λ）的方法。该常数可用于通过修正的大气扩散方程预测废水喷洒或曝气场所下风方向的气溶胶化致病微生物浓度。大肠杆菌在清晨运行时的平均λ为8.8×10⁻³s⁻¹，下午运行时的平均λ为6.6×10⁻²s⁻¹。
