Submerged plant repairing, culturing and loading system for underwater ecological remediation

Abstract

The invention discloses a submerged plant repairing, culturing and loading system for underwater ecological remediation. The system includes a buoyancy framework floating on the water surface, stretchable rod components and a supporting box body; the top end of each stretchable rod component is hung and buckled on the buoyancy framework, and the supporting box body is detachably connected with thebottoms of the stretchable rod components and sinks into the water; the top of the supporting box body is open, and an in-site bottom mud substrate layer is laid in the supporting box body and used for planting the submerged plants; by extracting substrates from the in-site bottom mud of to-be-restored fresh water areas such as creeks, rivers and lakes, evenly laying the substrates in the supporting box body and transplanting the submerged plants, a natural water plant bed ecosystem is directionally constructed with the artificial help, habitat and feed can be provided for aufwuch, benthonicanimals, fishes, shrimps and shells in the aquatic ecosystem, and meanwhile a propagation place can be provided for aquatic animals laying viscid eggs during a breeding season. Not only can a balancedecosystem be constructed and the utilization rate of high-quality water is increased, but also the aquatic ecological environment of low-quality water can be improved, and the ecological benefits ofthe aquatic system can be shown.

Description

technical field [0001] The invention relates to the technical field of aquatic weed cultivation systems in natural waters, in particular to an underwater in-situ ecological restoration submerged aquatic weed cultivation and loading system. Background technique [0002] The discharge of urban sewage, industrial and agricultural wastewater, etc. has made the range of black and odorous water bodies in many rivers, rivers, rivers, and lakes more and more extensive, and the pollution of organic matter in water bodies has intensified. Organisms died, and some waters even became desertified. At present, most of the treatment methods for poor-quality water bodies at home and abroad are to use physical, chemical and microbial methods to reduce the content of nutrients and organic matter in a targeted manner. governance, it is difficult to maintain a good ecological restoration effect. [0003] For the above-mentioned water body environment, the effective way to restore the natural ...

AI Technical Summary

Problems solved by technology

[0004] In order to take into account the needs of urban development and the need to maintain the water ecological functions of waterways, many rivers, river courses, and streams have been built with dams to varying degrees, which greatly reduced the spread of the original river courses and riverbeds, resulting in the growth and breeding of submerged plants in the river courses. Habitats disappear, resulting in the loss of corresponding ecosystem services
