Control Optimization Based On Typical Regional Air Quality Composite Model

To effectively improve the quality of atmospheric environment of ChaoyangDistrict, macro prevent environmental pollution and provide scientific basis for themanagement and decision-making department of environmental protection,atmospheric environmental quality standards of Chaoyang District need to be planned.In this article, author collect the natural environment, pollution meteorologicalcharacteristics, atmospheric environmental processes, various regional sources ofpollution distribution and the emission of pollutants present situation information.Established in2010emissions inventories of Chaoyang District including SO2, NOx,PM10and VOCs, using emission factors, combined with the first national pollutioncensus data and the recent research on atmospheric emissions inventory of pollutionsources in Beijing conducted by Beijing University of Technology. When conductingthis article PM10related calculations, taking into account the contribution of SO2、NOx and VOCs for PM10. According to the Chaoyang District’s recent economic andsocial development, predict the major pollutants emissions of the planned annual zoneto2010as the base year. Establish multidimensional boxes model with Gaussian foratmospheric environmental quality forecast using the data of pollution source in2010annual heating season (December) and non-heating season (July). Based on theprediction of the air pollutants concentration in recent and planning years withAtmospheric environmental quality standards, calculate the atmosphericenvironmental capacity of Chaoyang District under the80%and85%compliance rate.In2010, Chaoyang District, when air quality compliance rate was85%, the PM10environmental capacity was17498.14t, when air quality winter compliance rate was85%, the SO2environmental capacity was18281.32t. Muti-dimensional multi-boxmodel is a atmospheric prediction model invented by Beijing University oftechnology and Regina University, which can reflect Physical and chemical removalmechanisms and effects of wind-direction variations, with four wind-direction groupsbeing introduced into its computational framework. It can also predict the air qualityof dieffrent regions. Researsh the air pollution control measures in the ChaoyangDistrict using the linear programming with coefficients interval. Formulate ChaoyangDistrict Planning Year atmospheric environmental quality standard planning scheme reference to the pollution emissions situation, governance situation and potential, thencalculate the social and economic benefits of the planning. When conducting thisarticle PM10related calculations, taking into account the contribution of SO2、NOxand VOCs for PM10.
