Abstract
Air pollution control is one of the most important issues in thecities of the developing countries. Based on an analysis of the local economic and technological development the paper puts forward 9 air pollution control schemes. They are 4 briquette schemes, 2 coal gas schemes, 1 centralized heating system and 2 comprehensive schemes. A comprehensive diffusion model combined with a 3-D advection-diffusion equation and the Gaussian puffmodel is developed and verified. According to the calculation ofpotential reduction of pollutant discharge and the correspondingair quality improvement made by each air pollution controlscheme, the paper then works out a feasible and comprehensiveair pollution control scheme, which is characterized by lowinvestment and better environmental benefits. When the scheme isefficiently carried out, 19.3% SO2 and 24.4% sootdischarge is to be reduced annually in the city. There is aclear descent of air pollution concentration. The daily mean concentration of SO2 and TSP declines 24.6–75.4%and 10.4–45.4%, respectively. SO2 concentation of the whole city does not exceed the second grade of the Ambient Air Quality Standard of China except at a few grid points.
