Abstract
In order to find out the environmental quality of groundwater around the ash yard of a power plant and ensure its green and sustainable operation,9 groundwater monitoring wells were built in the ash yard,and samples were collected,tested and analyzed through field geological environment survey,geological drilling construction,pumping test,groundwater pollution index evaluation and other technical means.The results show that the ash yard is located in the southeast wing of Yangmeishu complex basin syncline,and its distribution strata are mainly sandstone,mudstone and coal measures in the Upper Permian Longtan Formation.There is a linear relationship between the water inflow and the drawdown of the water level,and the unit water inflow is unchanged.The groundwater quality level of the ash yard is Class I to Class VI,and the pollution level changes greatly.The main pollutants are mainly sodium,sulfate,dissolved total solids,ammonia nitrogen,arsenic,manganese and pH,and the pollution sources are mainly related to the geological background and production activities of enterprises.关键词
