Hyporheic zone deposit and mesenchyme porous water collection apparatus

Abstract

The invention discloses a hyporheic zone deposit and mesenchyme porous water collection apparatus. The hyporheic zone deposit and mesenchyme porous water collection apparatus comprises a neck ring, anempty shell, a water pressure guide pipe, a casing pipe and a bottom cover; the casing pipe is arranged in the empty shell and used for collecting hyporheic zone deposit and accelerating the proliferation of microorganisms; the top end of the empty shell is connected with the neck ring, and the bottom end of the empty shell is provided with the bottom cover which can be opened and closed; the casing pipe is fixed on the center of the neck ring, and the neck ring is used for fixing the casing pipe and the water pressure guide pipe; and the water pressure guide pipe is respectively arranged between the casing pipe and the empty shell, the empty shell is provided with pores at different depths of a corresponding deposit layer, the water pressure guide pipe is respectively provided with a pore at different depths communicated with the pore of the empty shell and used for collecting the hyporheic zone mesenchyme porous water. By adopting the hyporheic zone deposit and mesenchyme porous water collection apparatus, for the shallow water rivers, the deposit and mesenchyme porous water at different depths can be collected. The hyporheic zone deposit and mesenchyme porous water collection apparatus also has the advantages of high collection efficiency, environmental friendliness and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a collection device for sediment and interstitial pore water in an underflow zone. Background technique [0002] The interaction between surface water and groundwater mainly occurs in the riverbed or laterally permeable sedimentary zone, which is also called the hyporheic zone. As an important transition zone for the dynamic interaction and mixing of surface water and groundwater, the hyporheic zone, whose physical characteristics and biogeochemical environment jointly carry the change process of water material and energy exchange, plays an indispensable role in the river and lake ecosystem. For the "liver of the river". It is not only an important ecological buffer zone, but also a major place for strong biological activities, water exchange, solute migration, metabolism and storage of pollutants in rivers. [0003] In recent years, with the random dischar...

AI Technical Summary

Problems solved by technology

[0003] In recent years, with the random discharge of industrial and agricultural sewage, river and lake ecosystems have been greatly damaged. Many reports claim that new organic pollutants such as persistent organic compounds, heavy metals, and phthalates have infiltrated into rivers and lakes. In the hyporheic zone, the safety of groundwater is seriously threatened. However, the current monitoring of pollutants in the subsurface zone sediments and interstitial pore water has not been fully carried out, so research on the subsurface zone is urgently needed.

[0004] At present, a variety of devices for collecting sediments in the subsurface zone and interstitial pore water have been developed. However, many devices inevitably collect the surface water of rivers and lakes into the interstitial pore water, which seriously affects the later research.

In addition, many devices only collect interstitial pore water, but cannot collect interstitial pore water at different depths
