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 is characterized in that: a reaction material well 17 is set in the surface source pollution area, a well wall pipe 3 is arranged on the inner wall of the reaction material well 17, and a pumping well 18 is inside the well wall pipe 3, and the filling The reaction material injection well 17 and the pumping well 18 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 impervious pipe 12. The well wall pipe 3 is provided with a filter pipe. The outer wall of the pipe 6 is provided with a medium composite material layer 2, and the upper su...

Abstract

The invention relates to a filling and water-pumping double-well treating method for treating polluted underground water. The filling and water-pumping double-well treating method for treating the polluted underground water is characterized in that a non-point source pollution area is provided with a filling reaction material well (17) and a water-pumping well (18) so as to form a 'filling and water-pumping' double-well; a filtering tube (6) is arranged on a water containing layer of a well wall tube (3); the upper portion of the well wall tube (3) is a waterproof tube (12); and a medium combined material layer (2) is arranged on the periphery of the filtering tube (6) on the well wall tube (3). The thickness of medium combined materials is determined according to pollution concentration of the underground water and the effect of the medium combined materials; reducing agents are injected in two ends of the medium combined material layer (2); by the injected reducing agents, removed materials can be recycled; a water quality monitoring instrument can dynamically monitor the quality of the underground water in real time; and water can be pumped through a water-pumping tube. The problems that non-point source pollution is difficult to treat and the underground water cannot be used are solved. The double purposes of removing pollutants and supplying water can be achieved by a single well.

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...
