An energy circulation active convection oxygenation ecological floating island

Abstract

The invention relates to an energy circulation active convection oxygenation ecological floating island, which comprises a floating platform, at least one oxygenation device, a microbial bed and landscape plants; the floating platform is fixed on the water surface by fixed anchors; On the platform, the microbial bed is located underwater and connected to the lower surface of the floating platform; the aeration device adopts electrolysis and up-and-down convection design, uses hydrogen fuel cells to recover and convert hydrogen generated by electrolysis of water into electrical energy, and combines solar power supply devices for electrical energy Supplement: The layout of the microbial bed and the water body below the floating body provide a good living space for the microorganisms. The present invention can reduce energy consumption through energy circulation, realize molecular-level oxygenation, and at the same time control waters to form up-and-down convection, effectively improve and control the overall dissolved oxygen in waters, activate the vitality of water bodies, assist in building a benign ecological balance, and realize the improvement of water quality in controlled waters and The energy cycle is maintained for a long time.

Description

technical field [0001] The invention relates to the fields of environmental protection technology and aquaculture, in particular to an energy cycle active convection oxygenation ecological floating island. Background technique [0002] With the development of my country's urbanization process, the urban population is dense, and the original urban sewage works are not perfect, resulting in a large amount of domestic sewage and industrial wastewater being directly discharged into urban rivers, causing serious river pollution, and a large number of black and smelly rivers have seriously affected urban residents. health and cause serious damage to urban water ecology. The management of the black and smelly river has become the top priority in the control of environmental pollution. The problem of black and smelly river governance is more critical to the long-term maintenance in the later period. At present, artificial oxygenation and ecological floating island technology are mos...

AI Technical Summary

Problems solved by technology

Artificial oxygenation has the problems of high energy consumption and high cost in long-term operation; conventional ecological floating islands mostly rely on the planting of aquatic plants on floating islands to absorb excess nutrients in the water body to maintain water quality, which has low efficiency and no effect on improving dissolved oxygen in water bodies. contribution, no effect on the nutrient enrichment area at the bottom of the water body, etc.

[0003] The most important reason for the black and smelly rivers is the discharge of a large amount of pollutants, which seriously exceeds the pollution-holding capacity of the urban river system. In addition, the fluidity and water exchange capacity of urban rivers are poor, and their self-purification ability is greatly inhibited. Increased pollution levels of urban rivers
