A solar-powered water cycle purification biological ecological island

Abstract

The invention discloses a solar-powered water cycle purification biological and ecological island, including a solar energy water circulation reoxygenation device, two microbial treatment tanks and two groups of ecological floating bed. The water outlets of the solar energy water circulation reoxygenation device and the two microbial treatment tanks are connected with T-shaped pipes; the ecological floating beds are above the microbial treatment tanks; The solar energy water circulation reoxygenation device drives the water in the treatment region water into the microbial treatment tanks; pollutants in the water can be removed under the action of immobilized microorganisms; the outlet water is drawn out by the solar energy water circulation reoxygenation device up to a water surface and slowly pushed out in laminar flow shape; and the whole circulation process not only promotes the flow of the water in the treatment region but realizes water reoxygenation. The invention uses solar energy, combines the circulation reoxygenation technology, immobilized microorganism technology and ecological floating bed technology, efficiently removes contaminants while enhancing the self-purification capacity of water bodies, in order to achieve in-situ remediation of contaminated water bodies; and the ecological floating island arrangement has certain landscape effects.

Description

technical field [0001] The invention belongs to the technical field of water environment ecological restoration, and relates to a biological ecological island utilizing solar energy-driven water cycle purification. Background technique [0002] In recent years, the rapid development of society and economy has also brought serious harm to the environment. The random discharge of industrial wastewater, domestic sewage and domestic garbage has caused large-scale eutrophication of surface waters such as some rivers and lakes. Eutrophication of water not only reduces the transparency of water and makes it difficult for sunlight to penetrate the water layer, thus affecting the photosynthesis of plants and the release of oxygen in the water. At the same time, the mass reproduction of plankton will consume oxygen in the water, causing a large number of aerobic organisms to die. Disturb aquatic ecosystems. On the other hand, the decomposition of organic substances accumulated at the...

AI Technical Summary

Problems solved by technology

The construction and restoration of water ecosystems are mainly based on ecological floating beds. The aquatic plants planted on the floating beds absorb and utilize excess nutrients in the water body. However, the growth of aquatic plants has obvious seasonality and the treatment cycle is long.

Moreover, most of the above technologies are single technologies at present, and only focus on improving a certain aspect of the water environment, so there are certain limitations for the purification of water bodies with different functions

[0004] At present, there are many methods for treating polluted water bodies. Among them, the patent with the authorization number CN 203238591 U: an ecological floating island for solar energy treatment of polluted water bodies, which discloses the use of solar energy to provide power to drive the rotation of biological runners, and to place devices inside the biological runners. There are technical solutions such as polypropylene suspension balls with immobilized microbial agents, and adsorption fillers added to aquatic planting baskets. This system mainly relies on the microorganisms in the biological runner to degrade the pollutants in the treated water, but the diameter of the runner is limited by the size. The limitation is relatively large. When the amount of treated water is large, the depth of the oxidation tank is limited. Therefore, this method has certain restrictions on the area and depth of the treated water area.

Patent No. CN 102674557 A: Solar Floating Island Water Restoration Complete Set of Equipment, which discloses a complete set of equipment for in-situ restoration of landscape water body using solar energy as power, aeration flow device and biological floating island system. The equipment is suitable for application It is used in small water bodies such as landscape water bodies, which limits its application in large areas of water

The patent with the authorization number CN102126783 A: micro-polluted open water restoration method and device, discloses a method of using solar water circulation and reoxygenation system to make water move through the filler unit suspended in the water, and then degrade the pollutants in the water. The microorganisms on the method carrier are easy to lose and the processing capacity is limited. There are certain requirements for the degree of water pollution, water area and water fluidity, and it is not suitable for use in seriously polluted water bodies.
