Jinchang City Analysis Of Atmospheric Sulfur Dioxide Pollution Control And Countermeasures

For a long time, the industry-led model of economic development leading to the city of Jinchang atmospheric sulphur dioxide pollution was increasing trend, of which the industrial process emissions of sulphur dioxide gases in the atmosphere is Jinchang the primary environmental pollutants.Based on long-standing industrial city of Jinchang, sulfur dioxide air pollution problem is more comprehensive, and in-depth comparison and analysis of Jinchang city of sulphur dioxide pollution control in an effective way. Major work is as follows:(1) 1996-2005, Jinchang city of atmospheric sulfur dioxide monitoring data for statistical analysis, the Jinchang city of sulfur dioxide air pollution concentrations of time and space distribution of summarized;(2) Analysis of topography, weather factors and other natural factors and the industrial structure, urban layout, environmental economic policies, and other social factors on integrated Jinchang city of sulfur dioxide air pollution;(3) Jinchang City in 2003 to point source, the source of value-based monitoring, screening the main point source, the source of research, simulation of the key sources of pollution in the city of Jinchang District and the second category three categories of the three areas to monitor the concentration of contributions Value, measured in control and comparative analysis of the key sources of pollution to the region on the concentration of sulphur dioxide pollutants contribution rate, the delineation of the scope focus on governance;Based on the above analysis, the paper recommends the adoption of the regulation and control measures to strengthen industrial restructuring, promoting the adjustment of city layout, and strengthen environmental management in economic and educational means to enhance environmental management capacity of government macro-control measures, such as sulphur dioxide pollution.At the same time, with Jinchuan Company "11th Five-Year Plan" period has been completed and the sulphur dioxide gas or the proposed governance key construction projects, predicted "11th Five-Year Plan" period after the implementation of the project Jinchang City industrial sulfur dioxide emissions and the major monitoring points Concentration of value. Come to the conclusion: if the emission reduction measures to ensure the implementation as scheduled and is expected to 2010, the industrial city of Jinchang city of sulphur dioxide emissions will be reduced to almost total control of environmental capacity target, so that the urban environment are fundamental to improve air quality.
