高斯模式中无量纲臭气浓度的预测技术

Forecast Technology of Dimensionless Odor Concentration Based on Gauss Model

根据臭气浓度的测定原理,嗅阈值的定义,论述了《恶臭测定三点比较式臭袋法》监测的无量纲臭气浓度(倍)的转换的理论基础,推导了从标准方法的以体积浓度表示的稀释倍数转换为有量纲的排放强度,即常规的以质量为单位的排放强度,从而解决臭气浓度不能在常规大气预测模式中进行预测的问题。以臭气浓度(无量纲)为单位,在大气预测中不仅可以得出臭气在不同距离的臭气浓度,而且可以计算出达到嗅阈值(无臭)的距离。以甲硫醇为例,验证了量纲转换的合理可行性。

According to the determination principle of odor concentration and the definition of olfactory threshold value,this paper elaborates the theoretical basis of monitoring the transition of dimensionless odor concentration（ times） based on Air quality-Determination of odor-Triangle odor bag method,and deducts from the standard method that is using volume concentration as the dilution multiple to dimensional emissions rate,i. e. the conventional quality-based emissions rate,and there by solves the problem that the odor concentration can＇t be forecasted in the conventional atmosphere forecast mode. Using odor concentration（ dimensionless） as the unit,not only can we forecast the odor concentration in different distances in atmosphere forecast,but also can calculate the distance to reach the olfactory threshold value（ odorless）. Take methyl mercaptan as an example to demonstrate the reasonable feasibility of dimension transition.
