Characteristics Of Water Resources Of Rich Strontium Mineral Water In Tianjiazhai,Fugu County

Drinking natural mineral water refers to the underground mineral water which is not disturbed by human activities and the water quality is not damaged,which often contains minerals and trace elements necessary for human beings.In recent years,the quality of life of the people is rising day by day,and the demand for drinking water is also gradually improving.Drinking natural mineral water has thus entered the vision of consumers and has gradually been loved by the masses.Fugu County is located in the Mu Us desert area in northwest China.For a long time,groundwater has assumed the role of local water supply source and resource supply.Strontium-rich mineral water occurs in the underlying carbonate strata in the Shimachuan River basin.Drinking strontium-rich mineral water has different benefits to human skin,bone and blood vessels,so the local strontium-rich mineral water has certain economic benefits and can also provide help for the masses to strengthen their health.The study of the chemical characteristics,formation mechanism and allowable mining capacity of Tianjiazhai strontium rich mineral water can provide scientific guidance for the local development and utilization of strontium rich mineral water.The study of the chemical characteristics and allowable mining capacity of Tianjiazhai strontium rich mineral water can provide scientific guidance for the local development and utilization of strontium rich mineral water.In order to protect the local groundwater environment,avoid environmental geological hazards and maximize the economic benefits of strontium-rich groundwater,this paper studies the hydrochemical characteristics,ion enrichment law,formation process control terminal element and source of strontium by collecting water samples of groundwater and surface water and taking the locally existing strontium-rich mineral water as the research object,and numerically simulates the groundwater system with the purpose of studying the local reasonable exploitation quantity.The results are as follows:（1）The groundwater p H range is 7.5～8.34,the average is 7.97,the total is weak alkaline,the TDS concentration range is 316～718 mg/L,the average concentration is 472.36.All hydrochemical types are HCO₃-Ca·Mg water.Ion concentration distribution characteristics are similar to TDS distribution characteristics,mainly showing the upper reaches of the Shimachuan River than the downstream enrichment characteristics.（2）The main controlling end element of formation of groundwater chemical characteristics in the study area is rock weathering.The leaching effect of atmospheric precipitation on the rocks in the area is also one of the reasons for its formation.In the study area,weathering dissolution,cation alternating adsorption and carbonic acid equilibrium are common in groundwater.The extraction of groundwater will not have a significant effect on ion enrichment and Strength of hydrogeochemistry.（3）The strontium in the study area comes from leaching of potassium feldspar in Yanchang formation.The higher the weathering degree,the lower the strontium content.The longer the surface leaching time,the lower the strontium content.（4）The numerical model results show that the groundwater level does not decrease seriously and the groundwater storage does not change with time under the condition of the multi-year stability of 620 m³/d,so it is determined that the allowable exploitation amount of strontium rich mineral water in m3/d.study area is 620 m³/d...
