Embodiment Construction

[0037] Such as figure 1 , figure 2 As shown, the groundwater high-fidelity sampling system of the present invention includes a deep-water well sampling device 5 near the liquid surface, a mass stabilizer 3 , a laminar flow sampler 2 and a sampling bottle 1 .

[0038] The deep water well sampling device 5 facing the liquid surface includes a submersible pump 52 , a drainage body 54 , a drainage cover 53 , a water inlet pipe 58 and a flower net pipe pendant 59 and the like.

[0039] The submersible pump 52 is a vertical cylindrical pump body, and the water outlet 51 on the top of the pump body is connected with a water outlet pipe 57 for transporting the collected water to the ground. The length of the tick marks.

[0040] The upper part of the drainage body 54 is a cylindrical pipe body, and the lower part is a cone structure with the tip facing downwards. It is installed on the lower end of the submersible pump 52. The centerlines of the upper cylindrical body of 54 and th...

Abstract

The invention provides a groundwater high-fidelity sampling system and a sampling method. The groundwater high-fidelity sampling system is a deep-water well sampling device near the liquid surface for pumping groundwater under the liquid surface in the well pipe. The deep-water well sampling device near the liquid surface The outlet pipe installed on the top of the tank is in turn connected with the mass stabilizer, the laminar flow sampler and the sampling bottle arranged on the ground. During the sampling process of the groundwater high-fidelity sampling system of the present invention, the water sample enters from the flower net pipe pendant at the lower end of the deep water well sampling device facing the liquid surface, and finally flows into the sampling bottle. The pumping flow rate is controlled by adjusting the flow regulator, so that the sampled water flow It is stable and realizes micro-disturbance pumping, which can effectively reduce the chance of volatile substances in the water overflowing and improve the fidelity of water samples. The deep-water well sampling device placed in water of the present invention has a simple structure and low energy consumption, and can solve the problems of high energy consumption of conventional sampling equipment, limited depth of sampling points, and the like.

Description

technical field [0001] The invention relates to a sampling system for sampling groundwater, in particular to a high-fidelity groundwater sampling system and a sampling method. Background technique [0002] In-situ leaching mining is a relatively advanced and environment-friendly mining technology at present. Its basic principle is to arrange technical drilling holes according to a certain mesh within the range of ore-bearing layers that can be mined by in-situ leaching, and inject the leaching solution from the injection holes into the ore-bearing layer. The leaching solution mainly reacts with the target minerals in the ore-bearing layer, dissolves to form a leaching solution, and the leaching solution is brought to the surface through the pumping hole. After the target minerals are extracted in the surface factory, the leaching agent is added to the discharged tail liquid to form a leaching solution. The process of re-injecting the liquid through the injection hole into th...
