Applicaton method of scrap tires in process of steadily converting alga type lake into grass type lake

Abstract

The present invention belongs to the technical field of ecological restoration, and provides an application method of scrap tires in a process of steadily converting an alga type lake into a grass type lake. Directed at the problems such as large wind and wave disturbance from large shallow lakes, difficulty in automatically gathering floating cyanobacteria in a downwind salvage zone, easiness for captive waterhyacinth in an open water to escape, lack of shelters for benthos and bivalve benthos, difficulty in rooting and proneness to floating for submersed plants at the bottom of hardground lakes and easiness for newborn shoots of delivered conchs, mussels, corbiculae, large cladocera and aquatic plants to be grazed by fishes and the like, a plurality of scrap tires are used as a component in the application method. The components comprise: multi-channel buoyant-raft type scrap tire wave absorption bands, a floating type scrap tire wave-permeable breakwater, oddly toroidal-shaped waters between a plurality of canted trapezoidal-shaped buoyant-raft type scrap tire wave absorption bands, a floating type scrap tire captivity fence, a scrap tire copying bottomless pot, a scrap tire artificial reef, and enclosures of a non-fish area and a little-fish area are cooperatively disposed. By applying the method, the purpose of steadily converting the alga type lake into the grass type lake is achieved.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to an application method of waste tires in the process of steady-state conversion of algae-type lakes into grass-type lakes. Background technique [0002] At present, there are many methods to control algal lakes, including: chemical methods, physical methods, biological manipulation methods, coastal wetland reconstruction, ecological restoration in enclosures, etc., but in the process of governance, almost all of them are The impact of strong winds and waves on the lake has not been effectively controlled, resulting in slow progress in governance effects. [0003] The research and application results show that shallow lakes accumulate many pollutants in the bottom mud, and these pollutants are easily released with the suspension of sediments under the action of strong winds and waves. When extreme weather such as strong winds, tropical storms, and thunder...

AI Technical Summary

Problems solved by technology

[0004] 1 75%-98% direct damage to aquatic plants;

[0005] 2 Cause pollutants nitrogen and phosphorus (NH 4 + -N, PO 4 3- The continuous release of -p) increases the chaos of the water body and reduces the transparency, leading to the rapid demise of submerged plants. The goal of steady-state transformation of algae-type lakes into grass-type lakes cannot be achieved;

[0006] 3 Causing erosion and collapse of the lakeshore

[0009] 2 Large-scale captive water hyacinths in open waters, due to the effect of wind and waves, ordinary floating mesh fences have a simple structure and no wave dissipation function, and are easily damaged by wind and waves. At the same time, a large number of captive water hyacinths escape;

[0010] 3 The accumulation of dead cyanobacteria and polluted sediment are the material basis for the formation of lake flooding. Therefore, waters rich in these two types of substances must be prone to lake flooding. In winter and spring, various floating garbage enters with the wind and waves. The accumulation of water in the downwind area is cumbersome and inconvenient to operate by manual salvage; in summer and autumn, floating cyanobacteria also enter the water area of ​​the downwind area to accumulate with the wind and waves. In this water area, the method of dragging the oil boom Gathering and salvaging cyanobacteria is cumbersome and inconvenient to operate. After the task of salvaging cyanobacteria and water hyacinth is completed, no wave dissipation measures have been taken in its waters. At the same time, it is also the main reason why lake flooding cannot be eliminated;

[0012] 5 Lack of shelters for zooplankton, benthos and bivalves;

[0013] 6 It is difficult for the submerged plants on the bottom of the lake to take root and float easily;

[0014] 7 After the aquatic plants are successfully restored in the enclosure, the enclosure will be removed when the water outside the enclosure is still in a state of severe eutrophication, resulting in the rapid demise of the aquatic plants in the enclosure, which will destroy the previous ecological restoration. at once

[0016] In the 1960s, foreign countries carried out research and use of waste tire floating breakwaters at sea. Domestic waste tire floating breakwaters are mainly used to defend against waves from the open sea and provide a stable working environment for ports. Limited by the hydrological environment, Its anti-wave effect is not ideal, and there are few practical engineering applications, and no application for wave dissipation in shallow lakes has been seen.
