Riverway microhabitat reforming and water quality purifying device

Abstract

The invention provides a riverway microhabitat reforming and water quality purifying device. The riverway microhabitat reforming and water quality purifying device comprises a plurality of wooden piles arranged on the river bank. Block stone is inlaid between the wooden piles. The wooded piles and the block stone define a periphery structure. The wooden piles are gradually shorter in the water flow direction of the riverway. The block stone, gravel and silt are sequentially laid inside the wooden piles and form an aquatic plant plantation base material. In the water flow direction of the riverway, emergent aquatic plants and submerged plants are sequentially planted on the silt. The riverway microhabitat reforming and water quality purifying device can purify water quality, provide inhabitant and propagation space and bait sources for aquatic organisms, enrich the biological diversity of the riverway and form a submerged forest landscape effect, has high flood fighting capacity, can manufacture complicated flow state and has high discharge capacity.

Description

technical field [0001] The invention relates to a river channel micro-habitat improvement and water quality purification device, belonging to the technical field of water ecological restoration. Background technique [0002] Rivers have formed various complex forms in the course of natural evolution, providing aquatic organisms with a variety of habitat forms. However, in order to eliminate the flood disasters caused by meandering rivers and silting, people have carried out a large number of reconstruction projects on rivers and river banks, making many rivers have a single habitat form and low water purification capacity, which in turn leads to deterioration of water quality and decline in biodiversity. water ecological problems. [0003] In order to enrich the habitat form of the river, especially the flow state in the river, people put forward the idea of ​​building structures in the river, such as spur dams. Spur dikes can protect the river bank from scour damage cause...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a river channel micro-habitat modification and water quality purification device. The river channel micro-habitat modification and water quality purification device solves the problems of artificial rivers with a single flow pattern, lack of aquatic plants with water purification functions, and water body self-purification capabilities. Limited and other water environment problems, enhance the value of river landscape
