Abstract: As the environment consciousness of people is enhanced, more and more public concentration focuses on the location and operation decision of waste disposal facilities. The measurement of obnoxious effect is not only the focus in location optimization of these facilities, but also the key factor in the evaluation and control of noxious effect of facilities in operation. In this paper, some improvement is made on Gaussian Plume Model to make it applicable to measurement of pollutant concentration of waste disposal facilities. A mathematic model based on various scenarios is established to calculate the gas concentration, the multi-facilities, multi-kinds of gas, multi-directions of wind and multi-kinds of atmospheric stability are taken into account simultaneously in the model. An obnoxious effect measuring function is devised. A virtual example is designed to test the model and the parameter analysis is carried based on the example.

Key words: Gaussian Plume Model (GPM), waste disposal facilities, obnoxious effect measurement
