Solar-powered water cycle purification biological and 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 driven by solar energy for water cycle purification. Background technique [0002] In recent years, the rapid development of social 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 some rivers, lakes and other surface waters. The eutrophication of the water body not only reduces the transparency of the water, but also makes it difficult for sunlight to penetrate the water layer, thereby affecting the photosynthesis of plants in the water and the release of oxygen. At the same time, the massive reproduction of plankton will consume the oxygen in the water, resulting in the death of aerobic organisms in large numbers. Disturb aquatic ecosystems. On the other hand, the decomposition of or...

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 which patent No. CN203238591U: 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 the biological runners are equipped with fixed Technical schemes such as polypropylene suspension balls with oxidized microbial agents, and adsorption fillers added to aquatic planting baskets. The system mainly relies on the microorganisms in the biological runner to degrade the pollutants in the treated water area, but the diameter of the runner is limited by the size. When the amount of treated water is large, the depth of the oxidation tank is limited, so this method has certain restrictions on the area and depth of the treated water area.

Patent No. CN102674557A: Solar Floating Island Water Restoration Complete Set of Equipment, which discloses a complete set of equipment for in-situ restoration of landscape water using solar energy as power, aeration flow device and biological floating island system. The equipment is suitable for landscape Small water bodies such as water bodies limit its application in large areas of water

The patent with the authorization number CN102126783A: micro-polluted open water repair 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 method The microorganisms on the 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. It is not suitable for use in seriously polluted water bodies.
