Embodiment Construction

[0039] Such as figure 1 , figure 2As shown, the surface water high-fidelity ultra-deep sampling system of the present invention includes a sampling platform 4 , a deep water sampling device 5 near the liquid surface, a mass stabilizer 3 , a laminar flow sampler 2 and a sampling bottle 1 .

[0040] The sampling platform 4 is similar to the hull structure, floating on the liquid surface above the surface water sampling area, and is used to provide installation and placement points for other sampling device components.

[0041] The deep water sampling device 5 near 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.

[0042] The submersible pump 52 is a vertical cylindrical pump body. The water outlet 51 on the top of the pump body is connected with an outlet pipe 57 for transporting and collecting water samples. the tick mark.

[0043] The upper part of the drainag...

Abstract

The invention provides a surface water high-fidelity ultra-deep sampling system and a sampling method. The surface water high-fidelity ultra-deep sampling system includes a sampling platform, a deep water sampling device near the liquid surface, a mass stabilizer, a laminar flow sampler and a sampling bottle; The platform floats on the surface water surface and is used to place the working parts; the deep water sampling device near the liquid surface is used to pump the surface water deep below the liquid surface; the mass stabilizer is used to stabilize the collected water samples, and the water The volatile and semi-volatile substances precipitated in the sample; the laminar flow sampler is placed on the sampling platform and connected to the water intake pipeline after the mass stabilizer to adjust the water flow and flow rate of the collected water samples and improve the fidelity of the samples ; The sampling bottle is used to collect the collected water samples output by the laminar flow sampler. The invention avoids the volatile substances and oxygen-sensitive substances in the sample from being separated from the water body or denatured during the sampling process, thereby ensuring the authenticity of the collected water samples and solving the problem that the water samples are easily distorted.

Description

technical field [0001] The invention relates to a sampling system for sampling surface water, in particular to a high-fidelity ultra-deep sampling system and a sampling method for surface water. Background technique [0002] Surface water resources are closely related to human life and production activities, providing us with domestic and production water, aquatic products and some mineral resources. With the progress of human civilization, on the one hand, the degree of human dependence on surface water resources is increasing day by day, and on the other hand, the degree of human pollution to surface water resources is also increasing. Therefore, it is particularly important to protect the surface water environment. In order to realize the protection of the surface water environment, it is also necessary to carry out all-round monitoring to grasp the quality of the water environment in time. [0003] At present, the monitoring methods of surface water environment can be ...
