Simulation of sulfur deposition from coal-fired power plants in Guizhou province
3-D dynamic flow field model and advective diffusion equations in terrain-following coordinate system were used to simulate distributions of sulfur deposition of Guizhou province in 1999 and 2010 after power plan is realized. The results show that the distribution of sulfur deposition accords with the emission sources. Whether desulfurization is taken by power plants according to the requirement for acid rain control area or not, the area where sulfur deposition exceeds 10eq/hm/a enlarges from half of the province in 1999 to almost the whole province in 2010.The highest sulfur deposition increases from 2000eq/hm/a in 1999 to 2300eq/hm/a (with desulfurization being taken by power plants) or 3300eq/hm/a (no desulfurization being taken by power plants) in 2010.The area where sulfur deposition exceeds critical load is about 612km2 in 1999, and the areas are 324km2 or 4284km2 for the cases that desulfurization is taken by power plants or not, respectively.
