摘要: 采用ATMOS长距离传输模型,对2006—2007年山西省燃煤电厂通过关停小机组及增设脱硫设施所减少的SO2排放量进行数值模拟,并基于地理信息系统,分析了整个模拟范围内的总S沉降和干/湿S沉降分布特点,探讨了关停小机组及增设脱硫设施减少SO2排放量的效果。结果表明:2006—2007年间山西省燃煤电厂装机容量增加,但SO2排放及其导致的S沉降量持续下降,表明二氧化硫减排效果非常明显。

Abstract: The amount of SO2 emission reduction closing down small thermal power generating units and increasing sulfur deposition establishment at the coal-fired power plants from 2006 to 2007 in Shanxi province were simulated with ATMOS long distance transmission model. The distributions of the total sulfur deposition and dry/wet sulfur deposition in study areas were analyzed based on the geographic information system (GIS). The effects of SO2 emission reduction were discussed. The results show that the capacity of thermal power plant increases from 2006 to 2007. However, SO2 emission and sulfur deposition decreases persistently. It indicates that the effect of SO2 emission reduction is better.
