Aquatic plant fixing device for repairing water and bottom mud

Abstract

The invention provides an aquatic plant fixing device for repairing water and bottom mud, and belongs to the field of a water pollution recovery technique in environmental protection. The device comprises a submerged plant fixing frame, two floating frames, a nylon net, an ecological floating plate, a sliding rail, a connecting rope and a plant growth substrate, wherein the frames are used for including emergent plants, floating plants and submerged plants into a same system, the frames are connected through a connecting rope to form a triangular stable structure, two floating frames are used for respectively planting the emergent plants and the floating plants, a submerged frame is connected with a submerged plant growing substrate, the water and the bottom mud are repaired by the submerged plants, microbes are doped in the submerged plant growing substrate to promote the plants to absorb and convert pollutants to realize microbe-plant combined repair. According to the aquatic plant fixing device provided by the invention, the optimization of types of plants and space structure can be realized, environment can be beautified, and water quality can be purified; meanwhile, the water and the bottom mud can be repaired, and more thorough and effective repair can be realized.

Description

technical field [0001] The invention relates to the technical field of water pollution remediation in environmental protection, in particular to an aquatic plant fixing device for remediating water bodies and bottom mud. Background technique [0002] With the acceleration of the industrialization process, the development of the mining industry is in full swing, but the pollution generated in the process of mining, dressing and smelting cannot be ignored. Rivers, lakes and other water bodies suffer from varying degrees of heavy metal pollution, which not only damages water quality and affects the environment, but also enters the food chain with animals and plants, endangers the ecosystem and poses a threat to human health. [0003] There are many methods currently used for water pollution remediation, including phytoremediation, microbial remediation and ecological floating bed remediation. Ecological floating bed technology is a new type of water in-situ restoration technol...

AI Technical Summary

Problems solved by technology

[0004] The existing ecological floating beds are basically used to make plants float on the water surface, and only have a purification effect on the surface of the water body, while ignoring the restoration of deeper water areas, the restoration speed is often slow, and the treatment effect is not obvious; most ecological floating beds are only for A class of aquatic plants, such as emergent plants or floating plants, and there are few fixtures for submerged plants, and it is impossible to incorporate emergent plants, floating plants and submerged plants into a unified carrier at the same time, which cannot achieve all-round three-dimensional purification of water quality the goal of
