Songnen Plain Development Trend Of Water Quality Groundwater

Daily life of residents in the shallow groundwater is the main source of water,The water quality will have a direct impact on people's health,In recent years the rapid development of social economy,Songnen Plain industrial "three wastes ",sewage discharge and agricultural heavy use of fertilizers,pesticides,Resulting in one of the toxic and hazardous substances into groundwater caused,Groundwater overexploitation,Accelerated the migration of contaminants,Led to a series of water quality,Some rivers in the region has become a sewage river,Large areas of shallow groundwater contaminated,And further threaten the deep groundwater,The purpose of this research is to fully understand the water quality of shallow groundwater Songnen Plain variation,In order to take timely and effective protection and management measures,Promote the sustainable use of groundwater。Based on this detailed information on regional geology and water quality,On Improuing characteristics of water quality of shallow groundwater and protection of water resources were analyzed,Three results obtained:First,analysis and research of the Songnen Plain geological,geomorphological and hydrogeological conditions,And analyzed the variation of groundwater quality within the region and under the influence of human activities,changes in water quality characteristics。Second,the water quality of groundwater under the Songnen,Causes of pollution are analyzed,And the main pollutants in the region F-,salinity,total hardness,nitrate index,potassium permanganate and manganese ion concentrations were analyzed , Drawn 80 and 2005 , the typical ion concentration contours and comparison chart to compare the concentration of the deteriorating water quality of shallow groundwater。 Third,the region has made specific groundwater protection program,developed pollution control measures and rational development and utilization of groundwater and other groundwater protection programs。Songnen Plain,through research that is a complete water system,the shallow groundwater within the region in which the main geological environment under its influence,but in recent years by the man-made and natural water supply of large,focus on the protection of groundwater resources in the groundwater Recharge area。This study to guide the protection of groundwater resources Songnen Plain has a good practical significance,while other areas of groundwater quality and groundwater protection,good reference。...
