基于水力调控的地下水BTEX污染控制与修复模拟试验研究
Simulation test study on groundwater BTEX pollution control and remediation based on hydraulic regulation
摘要
Abstract
Groundwater hydraulic control is an effective groundwater pollution control and remediation technology,which is widely used in groundwater pollution prevention and control.Leveraging a multifunctional simulation device for groundwater pollution migration and in-situ remediation,an experimental study was conducted on the control and remediation of underground water BTEX pollution using hydraulic control combined with in-situ microbial remediation.The research involved the comprehensive analysis of the applicable conditions for different well layouts,pumping rates,and pumping durations in hydraulic control.Factors such as hydrogeological conditions of the contaminated site and the properties of pollutants were considered as determining elements.Based on the simulation experiments,the following conclusions were drawn:the combined pumping and injection hydraulic control method accelerated the migration speed of the pollution plume by approximately 1 time,with the peak concentration of pollutants decreasing by up to 83%.The polluted groundwater flow downstream decreased by 74%,effectively controlling the pollution plume.When hydraulic control was combined with in-situ microbial remediation,the pollutant concentration under hydraulic control conditions was only about 0.005%of that under conditions without hydraulic control,significantly enhancing the efficiency of BTEX degradation based on microbial activity.关键词
