Solar micro-power self-watering dry type ecological floating island

Abstract

The invention relates to environmental engineering and water treatment technology, and aims at providing a solar micro-power self-watering dry type ecological floating island applied to ecological restoration of eutrophic water and beautification of landscape water. The invention integrates the advantages of microbial technology, ecological floating island technology and solar energy technology to remove organics, nitrogen and phosphorus in the eutrophic water; meanwhile, dissolved oxygen in the water can be increased and self-purification capacity of the water can be enhanced by a solar watering device, and thereby better ecological restoration effect is achieved. The dry type floating island can be planted with multiple kinds of plants, thus playing a good role in enriching the ecological system of the floating island and facilitating birds and fishes inhabiting the floating island, and providing sufficient conditions for the naturalization of the floating island without producing secondary pollution to environment.

Description

technical field [0001] The invention relates to environmental engineering and water treatment technology, and aims to provide a solar micro-power self-irrigating dry ecological floating island for ecological restoration of eutrophic water body and beautification of garden landscape water body. Background technique [0002] In recent years, as people pay more and more attention to the living environment, the surrounding natural environment, especially the quality of the water environment and the state of the natural landscape on the water have also received more and more attention. With the rapid development of urban greening and beautification work, the number of landscape water bodies continues to increase. Due to the lack of fresh water sources, the water quality of some inner lakes, rivers or landscape water bodies in some cities continues to deteriorate, and the water bodies are eutrophic, causing excessive growth of algae and mass death of fish. damage to the aquatic en...

AI Technical Summary

Problems solved by technology

[0014] (1) Lack of power device, the contact with water is limited, and the purification effect cannot be fully exerted;

[0015] (2) Only using the absorption function of aquatic plant roots can only reduce nitrogen and phosphorus in water, without special microbial carriers, and its biofilm load is limited, making it difficult to reduce the content of organic pollutants in water, and reduce COD, BOD, etc.;

[0016] (3) It cannot increase the concentration of dissolved oxygen in the water, and it is difficult to promote the self-purification of the water body and improve the living environment of aquatic fish;

[0017] (4) The types of plants suitable for planting are too single, mainly concentrated in some large emergent plants, and the landscape effect cannot be reflected, which limits the application range of floating islands to a certain extent

Although the water purification effect of the wet floating island is good, the landscape effect of the floating island cannot be well reflected due to the single plant species. At the same time, it is difficult to improve the purification effect and replacement of plants, and it is often only water treatment. Appurtenances in engineering

[0021] On the other hand, dry floating islands can cultivate large-scale woody and horticultural plants because the plants are not in direct contact with the water body. Through different plant combinations, they can form a good biological habitat for birds, fish, etc., and also greatly beautify the environment. Landscape, but there are also some problems with dry floating islands. One is that there is no purification function of the floating island on the water body, and the other is that regular artificial watering is required to replenish the water needed for plant growth, which greatly increases the labor cost in the later stage.
