Freely rotating fish gill type oxygen purification system

Abstract

The invention discloses a fish-gill-type oxygen-carrying purification system capable of rotating freely. The system comprises a solar aeration region composed of a solar photovoltaic board, a controller, an inverter, a photovoltaic cable, a storage battery, a waterproof tank, an air pump, a fixed aeration pipe, a rotating aeration pipe and supporting original components. The fish-gill-type oxygen-carrying purification system is characterized in that the solar aeration unit is sequentially connected with a gill-filament-shaped oxygen dispersion-aerobic microorganism surviving region composed of rotating tee joints, an air spraying pipe, air dispersion holes, pumice and gill-filament-shaped active carbon fibers and a matrix filling aquatic plant purification region composed of emergent aquatic plants, submerged plants and hollow matrix filling baskets. Dissolved oxygen in water can be supplied on a large area, organic pollutants and nutritive salt can be efficiently removed, an aquatic ecosystem can be improved, and the system can help the water body to restore self-cleaning capacity, has the advantages of being attractive in appearance, simple in structure, economical and practical, and is suitable for treating and repairing common eutrophic water bodies.

Description

technical field [0001] The invention belongs to the technical field of oxygen-enriched water purification, in particular to a fish gill type oxygen-carrying purification system that can rotate freely. Background technique [0002] Water ecosystem is one of the most important ecosystems in nature, which plays an irreplaceable role in the development and progress of social economy. In the past few decades, humans have achieved water supply, power generation, shipping and other purposes by controlling and changing the natural form and hydrological characteristics of rivers and lakes. The cumulative effect of these factors has caused great changes in the aquatic ecosystem, coupled with the disorderly discharge of industrial wastewater and domestic sewage, resulting in river channel damage, runoff depletion, water quality deterioration, water self-purification ability reduction, and ecological function degradation; in addition, many The slopes of rivers and lakes are "hardened" ...

Problems solved by technology

Chinese patent application 201310756465.5 proposed a "solar aeration and oxygenation-plant bed with biofilm device", Chinese patent application 201310248096.9 proposed "an oxygen-rich nano-matrix composite ecological floating bed coupled with wind and light", Chinese patent application 200820156779.6 proposed a "wind-driven underwater aeration device", and Chinese patent application 201310245862.6 proposed a "synchronous in-situ restoration of eutrophic river and lake water and sediments that can enhance the oxygen-enriched biological fabric system". These schemes It provides an oxygen-rich method for the ecological restoration of eutrophic river and lake polluted water, solves the problem of low dissolved oxygen content in some areas of the water ecosystem, and can efficiently remove COD, nitrogen, phosphorus and other organic substances and other pollutants in the water. However, the diffusion range of dissolved oxygen is small, and it is difficult to achieve a wide range of oxygen enrichment in water ecosystems.
