Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to the following embodiments.

[0022] In this embodiment, a field test was carried out in a village in Shanyin County, Shuozhou City, Shanxi Province, my country as a test site. The schematic diagram of the overall structure of the obtained single well is shown in figure 1 As shown, the wellbore is provided with a PVC well pipe 4, a gauze permeable casing 6 and a sedimentation pipe 9 from top to bottom, the PVC well pipe 4 is fixed on the upper part of the wellbore, and the gauze permeable casing 6 is fixed on the wellbore The lower part is located at the aquifer in the formation, the sedimentation pipe 9 is connected to the lower part of the gauze permeable casing 6, and the PVC well pipe 4 and the gauze permeable casing 6 are tightly connected by threads. Wherein the ground pu...

Abstract

The invention provides a home-position arsenic removal single well based on siderite filter materials. The home-position arsenic removal single well at least comprises a ground pump room and a wellhole, wherein a well tube, a gauze permeable sleeve and a sediment tube are sequentially arranged in the wellhole from top to bottom, the well tube is fixed on the upper portion of the wellhole, the gauze permeable sleeve is fixed on the lower portion of the wellhole and located in the aquifer of the stratum, the sediment tube is connected to the lower portion of the gauze permeable sleeve, and the well tube is tightly connected with the gauze permeable sleeve through threads; space between the outer wall of the well tube and the well wall sequentially is filled with a concrete well fixing layer and a red soil protecting layer from top to bottom, the concrete well fixing layer is used for protecting and fixing the well tube, and space between the outer wall of the gauze permeable sleeve and the well wall is filled with a filter material layer; the bottom of the wellhole is further provided with a double-ring locator. The home-position arsenic removal single well is good in arsenic removing effect, simple in structure, capable of achieving the natural inferior underground water processing technique of underground normal-position arsenic removal, and capable of making a contribution towards resolving the problems of drinking water safety and body health of people in high-arsenic underground water areas in China, and the filter materials are cheap and easy to obtain.

Description

technical field [0001] The invention provides an in-situ arsenic removal single well, in particular relates to an in-situ arsenic removal single well based on siderite filter material, and belongs to the technical field of natural inferior and high-arsenic groundwater quality treatment. Background technique [0002] Arsenic is a toxic element that exists widely in nature and can cause serious harm to human health. When the arsenic content in groundwater is higher than 10 μg / L, it is high-arsenic groundwater. High-arsenic groundwater has the characteristics of wide distribution, large total amount, and difficulty in identifying the source and migration pathway of arsenic in water. Long-term drinking of high-arsenic groundwater will lead to chronic arsenic poisoning such as abnormal skin pigmentation, skin cancer, and visceral cancer, which will lead to endemic arsenic poisoning. [0003] However, in the vast water-deficient areas in northern my country, groundwater is the m...
