Energy circulating active convention oxygenating ecological floating island

Abstract

The invention relates to an energy circulating active convention oxygenating ecological floating island. The energy circulating active convention oxygenating ecological floating island comprises a floating table, at least one oxygenating device, a microbial bed and landscape plants. The floating table is fixed to the water surface through a fixing anchor. The oxygenating device and the landscape plants are fixed to the floating table, and the microbial bed is located underwater and connected with the lower surface of the floating table. Electrolysis and vertical convection design is adopted bythe oxygenating device, hydrogen generated by electrolysed water is recycled and converted into electric energy through a hydrogen cell, and electric energy supplementation is carried in combinationwith a solar power supply device. The microbial bed is arranged in water below a floating body, and provides good living space for microorganisms. According to the energy circulating active conventionoxygenating ecological floating island, energy consumption can be reduced through energy circulation, molecular-grade oxygenating is achieved, meanwhile, vertical convection is formed on a controlledwater area, the overall oxygen dissolving of the controlled water area is effectively improved, the vigor of the water is activated, benign ecological balance is auxiliarily built, and water qualityimprovement of the controlled water area and long-term maintenance of energy circulation are achieved.

Description

Technical field [0001] The invention relates to the field of environmental protection technology and aquaculture, in particular to an ecological floating island with active convection and oxygenation of energy circulation. Background technique [0002] With the development of my country’s urbanization process, the urban population is densely populated, and the original urban sewage engineering is imperfect, resulting in a large amount of domestic sewage and industrial waste water being directly discharged into urban rivers, causing serious river pollution and a large number of black and smelly rivers, which seriously affects urban residents The health of the city has caused serious damage to the urban water ecology. The treatment of the Heiwu River has become the top priority in the treatment of environmental pollution. The more important issue of the treatment of the Heiwu River is the long-term maintenance in the later period. At present, artificial aeration and ecological floa...

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
