Study On Predicting For Environmental Impact On Groundwater In A Mining Industrial Park

Groundwater is an important resource in daily life.Due to unreasonable exploitation and activities of human beings,the groundwater environment has been seriously polluted.How to protect the groundwater environment and achieve the win-win of developing and protecting is an urgent problem to be solved.Based on the investigation and monitoring of the groundwater environment,the types and characteristics of aquifers in the study area are investigated.The hydrogeological parameters and vulnerability of aquifers are calculated based on experimental data.Finally,the impact and trend of groundwater environmental pollution under the different scenario of pollution,such as planned sewage treatment stations and sewage treatment stations of key enterprises,are simulated.This study results provide a theoretical reference for the planning of the impact of industrial park construction on groundwater environment,and has important practical significance.The research results obtained as follows.(1)According to the hydrogeological survey,there are three main aquifers in the study area,the Quaternary gravel aquifer,Middle Ordovician limestone aquifer and Cambrian lime aquifer.(2)The assessment results of groundwater environmental quality shows,there is a poor groundwater quality in the study area.Some factor,such as Total hardness,TDS,sulfates,total coliform bacteria,have excessed the 3~rdd standard values of groundwater quality.The reason for exceeding the standard III may be related to the recharging of coking plant,coal washing plant and surface water in the park.(3)The results of groundwater environmental under normal conditions showed that the leakage of wastewater from sewage treatment plants has a greater impact on the downstream groundwater,the sensitive points closer to them,and the groundwater around the park.
