Research On The Simulation Of Air Pollutant Dispelling And Total Amount Of Pollution Control In Resource-type City

Currently,the middle-and small-sized cities of our country are all in the period of rapid economic development, not only the draining amount of old pollution source has the possibility of increasing, but also the new pollution source will continuously generate. Under such circumstances, it is an urgently unsolved problem at present time on how to control and manage the atmospheric pollution, so as to control and improve the atmospheric environment quality as well as to better the sustainable development of the economy. Proved by practice, it is an effective way to solve the problem of environment pollution by means of control the amount of atmospheric pollution. The control of the total amount is a way that by controlling the allowable total exhaust amount in definite area, to ensure the realization of quality objective of the atmospheric environment. Fuxin, as a typical coal resource-type city, has been suffering extremely serious atmospheric pollution. Due to this reason, by choosing the problem of atmospheric pollution as the research object, this article obviously has some important and practical meanings. This article collects the monitoring data of atmospheric environment of recent years, adopts the method of pollutant load rates, to analyze rule of atmospheric pollutant distribution in this area and the rule that the density of the air pollutant changes with the season and function areas, and ascertains that the main pollution factors for the urban atmosphere pollution are TSP and SO2. By using the classical gaussian diffusion model as well as depending on the air monitoring data and environmental meteorological data of Fuxin city, this article simulates the diffusion of air pollutants in the air, which is emmited by the primary pollution source in the urban area, and also analyzes the relevent results. The improved box pattern is adopted in this article to predict the environmental capacity of atmospheric pollutant of Fuxin urban area, and the method of A-P value control and the optimized theory are also synthetically applied to erect a model of the total amount of atmospheric pollutant for the resource-type city, so as to provide the scientific basis of how to harness the pollution.
