| Total emission control is an idea of environment administrant,what relatively is concentration control .Total emission control of atmospheric pollutant is to control air pollution from an integrated viewpoint,and it is an effective way for improving the quality of regional atmospheric environment to this pollution control method,two parts of content are typical .One is how to determine the total allowable emission of pollutant,the other is how to share the allowable emission in all the pollution sources .The two points form the foundation of all kinds of methods prevalent today for total emission control of atmospheric pollutant. Although previous methods have made much effect in practice,they are not to be perfect. Because of the complexity of the atmospheric system,no method for total emission control of atmospheric pollutant which is most universal,reliable,and feasible appears to be used in environmental protection yet .So,it's necessary to do deeper research on the method of total emission control of atmospheric pollutant.Firstly, it introduces the background, notion and connotation of total-amount control, analyses the development of total-amount control theories in domestic and overseas , among which total-amount control ideas in Japan and America are introduced in details , and the development of environmental protection in China is reviewed briefly.Secondly, according to the analysis of a great deal of literature,a review of the methods used widely in our country for the control of total emission of atmospheric pollutant is made. The text based on meteorological data of Tumen in recent ten years and pollutant source data of the city, with SO2 as program control factor and reach National Secondary Standard for environmental quality in the area as aim. The new way to make a plan for total emission control of atmospheric pollutant is presented in which the process of the control is divided into three steps. In the first step,an improved A-P Value method is used whose results are more accurate. In the second step, according to the concentration contribution of every pollution source to the controllable points,each source is allocated allowable emission amount. By doing so,each source's responsibility to maintain regional atmospheric quality is determined. In the third step,the control plan drawn in the former step is adjusted to the actual condition, deriving the best optimization solution of least investment and least reduction for the system. Finally, confirm total volume control programming plan for SO2 in Tumen zone finally.The text use three steps in total volume control programming for atmospheric pollution, realizing in deed organic connection of source strength optimization and economy optimization, also with A-P value method, mltisource method and optimization method connection, making the study result of it simple, practical and operability. It provides new method for establishing integrated governing plan in environmental nonattainment area. |
