Problems solved by technology

[0005] 1) The invention did not consider the specific situation of the river bank at the beginning of the design: the steepness of the river bank, the width of the river surface, the flow velocity of the water flow, poor adaptability to river sections with different appearances, and the purification cannot be performed according to the degree of erosion of the specific river bank. The structure is adjusted, the structure of the device is too solid, and the adaptability is poor
[0006] 2) This invention does not consider the cost problem in practical application: the protective structure of the river bank should be constructed according to the distance of the river course from the residential area and the standard of flood control requirements. For the river section in remote areas, the structure can be simplified according to the local actual conditions , on the premise of ensuring the basic functions, reduce the cost
[0007] 3) This invention uses a lot of masonry, reinforced concrete and other materials for slope protection. Although it has high stability, it destroys the connectivity of material, energy and information exchange between land and water in the horizontal direction of the river, and affects the original The purification function of some ecosystems
[0008] 4) This invention only considers the protection work under normal water level, but does not take into account the protection work of the river bank under the flood level, and there are potential safety hazards during the flood season of the river

Embodiment 1

[0047] Such as image 3 As shown in the figure, a continuous purification and utilization system for the ecological belt of the river slope channel retreat is composed of a water area management module 1, a water bank management module 2 and a land area management module 3.

[0048] Wherein, the water area management module 1 includes a deep groove-shoal transformation unit 110 and a gravel groove purification unit 120; the deep groove-shoal transformation unit 110 is a deep groove in which the longitudinal section of the water system presents alternating depths by stacking ecological bags 11 and the shape of the shoal, so as to improve the natural conditions of the receding ecological zone; the placement of the ecological bags 11 is arranged in a ladder shape, and the placement of the upper layer of ecological bags 11 is at the seam of the two lower ecological bags 11, The upper and lower layers of ecological bags 11 are connected by standard connecting buckles 111. According...

Embodiment 2

[0055] Such as Figure 5 As shown, the environmental investigation of the receding ecological zone of a certain river section in a certain area is carried out, and the survey data obtained are as follows: the river section has a high degree of regularity, the river flow rate is 1.2m / s, the river bank is severely eroded, and the distance from residential areas is relatively large. Nearby, with low dissolved oxygen content and poor water quality transparency, but it does not undertake the main function of flood discharge. The reconstruction plan for this river section is as follows: Figure 5 Shown:

[0056] 1) The deep groove-shoal reconstruction unit 110 is used to control the water area, and the longitudinal section of the water system presents the morphology of deep grooves and shoals with alternating depths and shallows by stacking ecological bags, so as to improve the natural conditions of the receding water ecological zone.

[0057] 2) The ecological brick protection un...

Embodiment 3

[0060] Such as Figure 6 As shown, the environmental survey of the receding ecological zone of a certain river section in a certain area is carried out, and the survey data obtained are as follows: the river surface width of this section is wide, the river flow rate is Figure 6 Shown:

[0061] 1) The deep groove gravel tank purification unit 120 is used to treat the water area. By imitating the wetland environment and creating an environment suitable for aerobic microorganisms, the pollutants in the water body can be degraded by plant roots and aerobic microorganisms to achieve continuous purification effect. The cultivated plants are asparagus.

[0062] 2) Use the solidification protection unit 220 to control the water bank, and stabilize the soil by adding a liquid solidification agent to solve the erosion problem of the soil slope. The cultivated plant is mushroom grass.

[0063] 3) The cutting protection unit 310 is used to control the land area. While stabilizing the s...

Abstract

The invention relates to the technical field of ecological protection, particularly to an in-river slope channel water recession ecological zone continuous purification and utilization system, which comprises a water area treatment module, a water bank treatment module and a land area treatment module, wherein the water area treatment module comprises a deep groove-shoal transformation unit and agravel groove purification unit, the water bank treatment module comprises an ecological brick protection unit and a solidification protection unit, and the land area treatment module comprises a cuttage protection unit and a plant reinforcement transformation unit. According to the invention, the modular structure is adopted, different units can be called for the water recession ecological zonesin different environments, and the problem solving way is flexible, so that the method has wide application range, the distinguished construction can be carried out according to the distance between the river channel and the residential area and the standard of flood control requirements, and the construction cost can be reduced on the premise of the ensuring of the basic function; and by combining the engineering transformation technology and the biocenosis configuration technology, the connectivity of transverse amphibious matter, energy and information exchange of the river is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ecological protection, in particular to a system for continuous purification and utilization of ecological belts in river-inflow slopes and ditches. Background technique [0002] Regressive ecological zone generally refers to the area where the water-land interface is intermittently submerged by water. As the link connecting aquatic and terrestrial ecosystems, the receding ecological zone can improve water quality in resisting floods, regulating runoff, maintaining water and soil, storing floods and fighting drought, degrading pollution, and purifying water. Aspects such as water ecosystems have irreplaceable effects of other systems. However, with the development of social economy, industry and agriculture, the continuous enhancement of human interference activities, and the increasing intensity of water resource utilization, the environmental capacity and ecological carrying capacity of more and more re...
