电厂粉煤灰场对地下水环境影响的初步研究

Initial study on influence of ash fields on circumambient groundwater

从我国火电厂粉煤灰的排放现状出发 ,以某电厂粉煤灰场为例 ,通过模拟现有灰场在运行期间对地下水水位水质影响的基础上 ,研究了治理平原型灰场对周围地下水环境影响的三种措施 :防渗墙、排水管和抽水井 ,并对三种措施进行数值模拟 ,最后得出在经济上和技术上均可行的治理方案 .

On the basis of one power plant's ash field, from the current situation of power plant's ash stock in China, influences of ash fields on water table and quality of groundwater around the circumstance are simulated, and three schemes, waterproof wall, drain pipes and pump wells, for preventing influences of plain ash field on the groundwater environment are studied. Finally, a numerical simulation on three schemes is carried out; and a practical treatment scheme either economically or technically, is concluded.
