Water sampling device and sampling method for analysis before geotechnical engineering sewage treatment

Abstract

The invention provides a water sampling device and a sampling method for analysis before geotechnical engineering sewage treatment, and relates to the technical field of water source sampling. The invention solves the problems that relative sampling inspection cannot be performed according to a specific distance during sampling in the prior art, so that impurities contained in multiple sections of sewage with the same distance and depth cannot be accurately detected, and the deviation is relatively large, a water sampling device can only perform sampling inspection on water sources with the same water level height, and whether the sewage in the area reaches the qualification criterion cannot be accurately determined. The water sampling device for analysis before geotechnical engineering sewage treatment comprises a shell cover, wherein three rectangular grooves are formed in the middle position of the bottom of the shell cover. Due to the fact that the left side of the first connecting piece is rotationally connected with the rotating rod B auxiliary rotating block, and the right side of the second connecting piece is rotationally connected with the rotating rod B auxiliary rotating block, when the rotating rod B rotates, the rotating rod A and the rotating rod C can be driven to rotate at the same time.

Description

technical field [0001] The invention belongs to the technical field of water source sampling, and more specifically relates to a water sampling device and a sampling method for pre-treatment analysis of sewage in geotechnical engineering. Background technique [0002] Geotechnical engineering is to solve rock mass and soil engineering problems, including foundation and foundation, slope and underground engineering, etc. A large amount of sewage will be generated during the mining process, which needs to be sampled and inspected to determine whether it meets the discharge standards. [0003] For example, the application number: CN202010042146.8 is an automatic step-by-step sampling device for sewage treatment, which relates to the technical field of river sewage treatment, and includes a shell. The middle part of the shell is provided with evenly distributed liquid chambers, and the inner wall of the shell is fixedly connected. There are evenly distributed positive plates, t...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a water sampling device and a sampling method for analysis of geotechnical engineering sewage before treatment, so as to solve the problem that the relative sampling inspection cannot be carried out according to a specific distance when sampling, so that it is impossible to accurately detect multiple sections of the same The impurities contained in the sewage at a distance lead to large deviations, and the water sample collection device can only conduct spot checks on water sources at the same water level, and cannot accurately determine whether the sewage in this area meets the qualification criteria
