Embodiment Construction

[0026] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of apparatuses or methods consistent with aspects of the present application.

[0027] This specific embodiment provides a new type of extraction well, which can perform multiple filtrations on groundwater, and the filtering effect increases layer by layer, which is beneficial to ensure the stability of the effluent, reduce the sand content of the effluent, and effectively prevent the blockage of the filter channel risks of.

[0028] In order to make the purpose, technical solution and advantages of...

Abstract

The invention relates to a novel extraction well. The novel extraction well includes a well body, the well body is internally equipped with an inner pipe and an outer pipe sleeved outside the inner pipe, the extension directions of the inner pipe and the outer pipe are both perpendicular to the horizontal plane, and the side walls of the inner pipe and outer pipe are both provided with a well screen structure. The space between the well body and the outer pipe is filled with a first layer of filter material, the space between the outer pipe and the inner pipe is filled with a second layer of filter material, and the fineness modulus of the first layer of filter material is larger than that of the second layer of filter material. The bottom of the inner pipe is sealed, and the inner pipe isinternally equipped with a water suction pipe. According to the arrangement, groundwater can undergo multiple filtering, and the filtering effect increases layer by layer, thus being conducive to ensuring the stability of effluent water, reducing the sand content of effluent water, and effectively preventing the risk of blocking filtering channels.

Description

technical field [0001] The present application relates to the technical field of groundwater pollution remediation, and more specifically, relates to a novel extraction well. Background technique [0002] Groundwater is a precious freshwater resource for human beings. However, with the continuous development of social industrialization, wastewater discharge, industrial waste residue, agricultural irrigation, landfill leakage, and damage to transportation pipelines and storage tanks for petrochemical raw materials may cause groundwater pollution. It makes the original tense water shortage problem more serious, and poses serious threats and challenges to human health, food safety, drinking water safety, regional ecological environment, sustainable economic and social development, and even social stability. Groundwater restoration has become a public concern and environmental issues of social concern. [0003] Groundwater extraction technology refers to the deployment of a cer...
