摘要
高硫燃料煤烟气中的CO_2是大气CO_2的一个重要来源.烟气中的SO_2是导致南方酸雨的主要原因.酸雨增强了地表水及地下水对石灰岩的溶蚀,间接地释放出CO_2.研究表明:S,C在自然界面上循环,可通过酸雨作用于碳酸盐岩石来实现,我国南方高硫燃料煤所形成的酸雨对石灰岩地区每年将间接释放出(6.48—6.73)×10^(10)molCO_2,从全球范围来看,受酸雨影响的石灰岩溶蚀量是温室气体CO_2的一个不容忽视的来源.
It is an important source for atmospheric CO2 that the CO2 is derived from the high-sulphur of fuel coal burning. The SO2 in the smoke is the major cause for the acid rain in South China. The acid rain strengthens the capacity of corrosion on the limestone by the surface water and groundwater. And the CO2 indirectly gives off. The research exhibits that the circulation of S and C on the natural surface turn to reality for the acid rain effecting on carbonate rock. The limestone region will undirectly discharge (6. 48-6. 73) × 1010mols CO2 annually in South China. Globally, the amount of the limestone dissolution effected by acid rain can not be neglected as a source of green gases.
