Research Of Regulation Of The Soil Leachate Contaminating Soil And Groundwater At Haizhou Mining Dumping Site

In order to guide control and harness of groundwater of mining area, have need of making a study of transition regulation and contaminative characteristic of contaminant in the groundwater. In base of investigation of geologic and hydrology, monitoring samples of soil and groundwater of mining dumping site and environment contaminate grade evaluation, Haizhou stripmine Fuxin ,Liaoning province, demonstrated that the soil leachate of mining dumping site is the main source of the groundwater contamination. Hereunder, took advantage of theoretics and methods of groundwater dynamics, environment agrology, finite analytic method, constructed coupling of groundwater flowing equation and groundwater quality equation model and combined local boundary condition, simulated the transition regulation of contamination in the groundwater and educed transition regulation and contaminative characteristic of contaminant in the groundwater. And compared with monitoring value in 2004, the result of simulation is reliable. Transition regulation and contaminative characteristic of contaminant in the groundwater of the thesis offers theoretical reference and designates direction to control and harness of groundwater of mining area in the future.
