Energy-saving and efficient ecological floating island

Abstract

The invention relates to an energy-saving and efficient ecological floating island. The whole ecological floating island equipment mainly comprises three functional regions, namely an aquatic plant region, a filler region and an aeration system region, an ecological floating island structure adopts a plastic material with stable performance, a main frame is built by using an assembling mode, so that transportation is facilitated, an aeration system is powered by using solar energy, the night aeration work of the aeration functional region is controlled through a photoinduction technology, so that dissolved oxygen of a water body can be increased, in addition, the energy consumption can be reduced, the aquatic plant region has adsorption and enrichment effects, a biological filter technology is coupled, so that the short flow of sewage at the cross section of the water body can be reduced, and the contact probability of a filler and pollutants can be increased. The energy-saving and efficient ecological floating island has the technical advantages that the problem that aquatic plants do not produce oxygen at night without photosynthesis, meanwhile, the problem that the content of the dissolved oxygen of the water body is low due to biological metabolism and oxygen consumption can be solved, the sewage treatment capacity is effectively improved, the landscape function is good, the cost is low, and the management is simple.

Description

Technical field [0001] The invention relates to the technical field of environmental purification and energy saving, in particular to an energy-saving high-efficiency ecological floating island. Background technique [0002] According to the "2016 China Environmental Quality Announcement" published by the Ministry of Ecology and Environment in 2017, Category V accounted for 6.9%, and Category V accounted for 8.6%, respectively, which declined. However, the overall water body conditions and the ten water tasks are still not optimistic. The eutrophication of rivers, lakes, rivers and other water bodies in our country is an important treatment area for special water treatment projects, and the commonly used treatment method is the use of ecological floating island technology.

[0003] In the prior art, the utility model patent with the publication number CN203461882U discloses an energy-saving ecological artificial floating island, which includes a floating platform with aquatic plants planted on the surface; there is an oxygen charging device under the floating platform, and there is an oxygen-charging device on the floating platform. The oxygen charging device is electrically connected to the power storage device, and the power storage device is electrically connected to the solar panel fixed on the floating platform, which increases the concentration of dissolved oxygen in the water body, promotes the metabolism of microorganisms, improves the effect of decontamination, and overcomes the difficulty of erecting electric wires. Large, high investment and operating costs; however, the transportation of the floating platform is not considered. Once a large number of products are put into use, the transportation cost will increase significantly

[0004] In the prior art, the invention patent with the publication number CN108529752A discloses an ecological floating island, which includes a purification pipe and an aquatic plant system on the purification pipe. A flow-making device is provided at the water inlet of the purification pipe. A water flow is formed inside the purification pipe, and an aeration device is provided between the water inlet and the water outlet of the purification pipe. The aeration device passes gas containing oxygen molecules into the water flow to form a connected air flow inside the purification pipe. In the anaerobic purification area and aerobic purification area, the ecological floating island has a complex structure, is not easy to assemble, wastes resources, and is very likely to cause secondary pollution to the water body. It has obvious shortcomings in reducing costs, improving environmental purification capabilities, and saving resources.

[0005] The ecological floating island is based on aquatic plants with relatively developed rhizosphere as the main body. Using the principle of soilless cultivation, bamboo strips, wood or other polymeric organic materials are used as water carriers to build a plant-microbe restoration system. Through plant absorption, enrichment and The degradation of microorganisms and the reduction of other pollutants such as organic matter or heavy metals in water bodies have become research and application hotspots at home and abroad; the current research directions are mainly focused on the stability, tolerance, durability, landscape, In terms of biological safety, economy, and management convenience, etc., the problem that plants on ecological floating islands will stop photosynthesis at night is ignored. Because plants need a lot of oxygen for metabolism, they will compete with other organisms in the water for oxygen, resulting in short-lived water bodies. hypoxia, which seriously threatens the life and health of aquatic organisms, and the adsorption capacity of plants on ecological floating islands is limited, and the treatment effect is not ideal
