Embodiment approach

[0012] The invention is a treatment method for a filling-pumping double well which is suitable for removing groundwater pollutants in non-point source polluted areas and taking into account water supply. With reference to accompanying drawing, specific embodiment is as follows:

[0013] A groundwater pollution filling-pumping double well treatment method, in which a reaction material well (17) is set in a non-point source pollution area, a well wall tube (3) is set on the inner wall of the reaction material well (17), and the well wall tube (3) For the pumping well (18), the reaction material well (17) and the pumping well (18) constitute a groundwater pollution filling-pumping double well, and the water-bearing layer of the well wall pipe (3) is provided with a filter pipe (6), and the well wall pipe (3) is provided with a filter pipe (6). The upper part of (3) is an impermeable pipe (12), the well wall pipe (3) is provided with a filter pipe (6) and the outer wall is provide...

Abstract

The invention relates to a groundwater pollution filling-pumping double well treatment method, which is characterized in that: a filling reaction material well (17) and a pumping well (18) are arranged in a non-point source pollution area to form a "filling-pumping" double well , the water-bearing layer of the well wall pipe (3) is provided with a filter pipe (6), the upper part of the well wall pipe (3) is an impermeable pipe (12), and the well wall pipe (3) is provided with the outer surface of the filter pipe (6). A medium composite material layer (2) is provided on the wall. The thickness of the medium composite material is determined according to the pollution concentration of groundwater and the effect of the medium composite material, and a reducing agent is injected into both ends of the medium composite material layer (2). The injection of the reducing agent , can make the removed material recycle, and install the water quality monitoring instrument, monitor the groundwater water quality dynamically in real time, and can pump water through the pumping pipe. Dual purpose of pollutant removal and water supply.

Description

technical field [0001] The invention belongs to the technical field of groundwater treatment, and is suitable for a large-scale groundwater polluted area, especially a groundwater pollution filling-pumping double well treatment method for recovering groundwater pollution in important water supply sources. Background technique [0002] Non-point source pollution includes agricultural non-point source pollution and urban non-point source pollution. With the development of economic society and agricultural intensification, groundwater environmental problems have gradually developed from point source pollution to non-point source pollution, and from cities to rural areas. Especially in the process of agricultural planting, a large amount of chemical fertilizers, organic fertilizers, and nitrogen-containing pollutants discharged by industry have been infiltrated into groundwater for a long time, and the nitrate content in groundwater has increased. The water quality of a large nu...
