Description

Technical Field

[0001] The present invention belongs to the technical field of groundwater treatment, and in particular relates to a groundwater single-hole multi-layer extraction treatment and repair device and method. Background Art

[0002] Groundwater refers to water stored in the rock voids below the ground. In a narrow sense, it refers to water in saturated aquifers below the groundwater surface. In the national standard "Hydrogeological Terminology" (GB / T14157-93), groundwater refers to various forms of gravity water buried below the surface.

[0003] At present, groundwater in some areas is polluted to a certain extent due to different environmental and geological influences, resulting in water containing oil, fungi, inorganic pollutants and organic pollutants seeping into the underground groundwater, causing groundwater pollution. The existing groundwater is not suitable for direct domestic use. Therefore, the groundwater needs to be pumped out for purification. However, most of the existing technologies are heavy metal pollution treatment or extraction treatment, and there are few in-situ treatments for organic pollution, resulting in incomplete water treatment and certain safety hazards for the public to use groundwater.

[0004] Moreover, the types of pollutants in different aquifers of groundwater are different. Some aquifers are polluted by fungi, some are polluted by oil, and some are polluted by inorganic or organic matter. The existing in-situ treatment technology is to dig a well, mix the water from each aquifer together, pump it up, and then carry out repair treatment. This method will cause waste of chemicals and affect the treatment effect of the chemicals. Because if some aquifers are not polluted, the mixing of clean water and the water of the polluted aquiclude will increase the amount of sewage to be treated, so it will cause waste of chemicals; since the types of pollutants in each aquifer are different, after the sewage from each aquifer is mixed together, the remaining pollutants will act on the chemicals used for specific pollutants, so it will affect the use effect of the chemicals.

[0005] In the prior art, in order to solve this problem, a well is drilled for each aquifer. Although this method avoids the waste of chemicals and the impact on the treatment effect of chemicals, it increases the cost of drilling wells. Summary of the invention

[0006] In view of the problems existing in the above-mentioned prior art, the present invention provides a groundwater single-hole multi-layer extraction, treatment and repair equipment and method. The technical problem to be solved by the present invention is to carry out differentiated treatment for the types of pollutants in each aquifer without increasing the cost of drilling wells.

[0007] In order to solve the above technical problems, the present invention provides a groundwater single-hole multi-layer extraction treatment and repair equipment, including a sleeve assembly, a water pumping pipe, a water pump and a sewage repair system;

[0009] The sewage remediation system includes a sewage monitoring unit, a control unit and a sewage treatment unit; the sewage monitoring unit and the sewage treatment unit are both connected to the outlet of the water pump, the sewage monitoring unit and the control unit are electrically connected, and the water pump and the control unit are electrically connected.

[0010] Furthermore, a partition is arranged inside the water pumping pipe member, and the plurality of partitions divide the interior of the water pumping pipe member into a plurality of water pumping chambers arranged along the axial direction.

[0011] Furthermore, a plurality of baffles are arranged inside the pumping chamber, the depth of the baffles is set according to the depth of each aquifer, and the baffles are arranged perpendicular to the axis.

[0013] Furthermore, a through hole is provided on the bottom baffle plate, and water holes are provided above the other baffle plates.

[0014] Furthermore, the outermost sleeve corresponds to the lowest aquifer, the second outermost sleeve corresponds to the second deepest aquifer, and so on.

[0015] Furthermore, each sleeve is connected by threads.

[0016] Furthermore, the bottom of the multi-sleeve is connected to the outer wall of the water pumping pipe through a sealing ring.

[0017] The present invention provides a method for extracting, treating and repairing groundwater from a single hole and multiple layers, using the above-mentioned groundwater extracting, treating and repairing equipment from a single hole and multiple layers, comprising the following steps:

[0018] Step S1: Start the water pumps above each pumping chamber;
