Description

Technical Field

[0001] The utility model belongs to a watershed ecological restoration device, in particular to a bank protection system with a watershed ecological restoration function. Background Art

[0002] River ecological restoration refers to the use of ecosystem principles and various methods to repair the biological communities and structures of damaged water ecosystems, rebuild healthy aquatic ecosystems, repair and strengthen the main functions of water ecosystems, and enable the ecosystem to achieve a virtuous cycle of overall coordination, self-sustaining and self-succession.

[0003] Protect and restore river systems to a state closer to nature, and use sustainable characteristics to increase the value of their ecosystems and biodiversity activities. That is, the process of repairing the physical, biological or ecological state of damaged rivers, so that the restored rivers are healthier and more stable than before restoration. The goals include: riparian zone stability, improved water quality, increased habitats, increased biodiversity, developed fisheries, aesthetics and entertainment, so that the rivers can become more natural. Impact assessment and monitoring include: ecological monitoring during and after the restoration, tracking and evaluation of the impacts caused, and predictive evaluation using models. Success or failure directly affects human production, life and health. The effect of restoration can be characterized by monitoring the population and number of aquatic large invertebrates, fish and wading birds, as well as the improvement of wetland habitats. When the system can maintain itself, it means that the restoration is complete. Watershed ecological restoration technology is one of the key measures to solve the increasingly serious water environment problems in the basin and improve the health of the basin ecosystem.

[0004] The most common method of watershed ecological restoration technology is ecological restoration, that is, by introducing suitable aquatic plants and aquatic organisms to restore the ecosystem structure and function of the river. The combination of "submerged plants + aquatic organisms" is often used, that is, submerged plants are planted in the mud at the bottom of the water body, and aquatic organisms are released in the water body at the same time. However, this combination has the following shortcomings:

[0005] 1. The structure of submerged plants at the bottom and aquatic organisms at the top is adopted. It is necessary to plant submerged plants at the bottom of the existing water body. The construction is difficult and the plants are difficult to survive. In addition, only submerged plants are used as aquatic plants, and the plant species are single, so the restoration effect is limited;

[0006] 2. Carrying out ecological restoration in the entire river basin requires large investment and makes subsequent operation and maintenance difficult;

[0007] 3. Restoration effect is limited if only ecological means are used for restoration. Summary of the invention

[0008] The purpose of the utility model is to provide a bank protection system with the function of watershed ecological restoration. Functional units are set up next to the water body in the basin, and a combination of biofilm method and ecological restoration method is used to achieve continuous ecological restoration of the output water body to be restored, thereby effectively removing pollutants in the water body in the basin, and effectively reducing the high investment and difficult operation and maintenance problems brought about by the ecological restoration of the entire basin.

[0017] In order to facilitate the output of materials from the biofilm treatment area, the preferred technical implementation method is that the material output end of the collecting pipe is connected to the material input end of the water ecological device via the first pump water inlet pipe and the first lifting pump.

The light-transmitting material can be made of high-strength glass or acrylic board material, which belongs to the existing technology and the applicant will not elaborate on it.

[0019] In order to facilitate the output of materials in the water ecological device, the preferred technical implementation method is that the treated water of the water ecological device is pumped into the water body in the basin through the second pump inlet pipe, the second lifting pump, and the second pump outlet pipe.

[0020] In order to effectively utilize solar energy, simplify equipment structure, and reduce operation and maintenance costs, the preferred technical implementation method is to also include a solar panel, and the power output end of the solar panel is connected to the first lifting pump and / or the second lifting pump and / or the blower.
