Embodiment Construction

[0027] The purpose of the present invention is to provide a hydraulic interception technology based on joint control with PRB to remove groundwater pollutants. Its steps include:

[0028] 1. Determine the location and scale of pollution sources, and identify the main pollutants in groundwater; identify the distribution pattern, scope and distribution characteristics of pollutant concentrations in the aquifer pollution plumes.

[0029] 2. Collect the hydrogeological data of the study area, and determine the hydrogeological parameters of the study area, such as permeability coefficient, water supply, infiltration recharge coefficient, etc.

[0030] 3. According to the hydrogeological conditions of the site, determine the main parameters such as the scale and shape of the hydraulic interception zone, the pumping volume of interception wells, the number and spacing of interception wells, the maximum interception width and the stagnation point. The parameters are determined as fol...

Abstract

The invention relates to the technical field of removing contaminants in underground water. To improve water quality by hydraulic power capturing technology and obtain good effects, the technical scheme adopted by the invention is a PRB joint control-based hydraulic power capturing method for removing the contaminants in the underground water. The method comprises steps of: 1) determining the position and the scale of a pollution source, and determining the main contaminants in the underground water; 2) collecting hydrogeological data of an research area, and determining hydrogeological parameters including the permeability coefficient, the specific yield and the infiltration supplement coefficient of the research area; 3) determining the main parameters comprising the scale and the form of a hydraulic power capturing zone, pumping load of capturing wells, the number of the capturing wells, the distance among the capturing wells, the maximum capturing width, and stationary points according to hydrogeological conditions of the site; and 4) determining the effective distance between the hydraulic power capturing zone and the PRB according to the form and size of a contamination plume, thus ensuring effective joint control to remove the contaminants in the underground water. The method is mainly used for removing the contaminants in the underground water.

Description

technical field [0001] The invention relates to a method for removing pollutants in groundwater, in particular to a hydraulic interception technology for jointly controlling and treating pollutants in groundwater with PRB. technical background [0002] Groundwater resources play an important role in our country's water resources. Because of its wide distribution, good water quality, strong regulation and storage capacity, and high water supply guarantee, groundwater resources are being developed and utilized more and more widely. However, with the development of society and economy, the massive discharge of industrial waste water and waste, agricultural pollutants, intensive livestock and poultry breeding and excessive use of nitrogen fertilizers, the arbitrary discharge of municipal solid waste, and the disorderly development of groundwater have gradually affected groundwater. Pollution. Groundwater pollution in my country has shown a trend of evolution from point to surfa...
