For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0033] Figure 2 This is a physical picture of the deep-water cabin-type artificial wetland treatment system of the present invention. DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Although artificial wetland technology is a sewage treatment technology with broad application prospects, there are certain problems in its promotion and use, mainly manifested in the following aspects: First, the hydraulic load of wetlands is limited, resulting in a large wetland area. Compared with conventional sewage treatment processes, artificial wetlands occupy at least twice the area, making it difficult to promote in places with tight land use or high land prices; second, as the operation time of wetlands increases, some nutrients will gradually accumulate. If they are not properly maintained, siltation, blockage, and clogging will easily occur, reducing hydraulic conductivity, wetland treatment efficiency, and operating life; third, as the sewage treatment process continues to operate, the adsorption capacity of the matrix will tend to be saturated after a few years, which will also affect the treatment effect of the wetland; fourth, aquatic plants and microorganisms need a certain amount of water to survive, so Artificial wetlands are difficult to resist drought climate; fifth, some subsurface flow wetlands that are not designed, constructed or maintained properly will cause surface water accumulation; sixth, surface flow wetlands have large water surfaces, which will cause a large number of mosquitoes and flies to breed, threatening the health of people around the wetlands; seventh, due to the existence of certain hypoxic and anaerobic zones in artificial wetlands, certain anaerobic reactants (such as H2S and odorous substances) will diffuse into the air and cause odor to spread; eighth, lower temperatures can weaken the various biological activities of wetland systems, and plants that stagnate or die during low temperatures will reduce their oxygen release capacity or even not release oxygen, thereby reducing or losing their ability to purify wastewater; ninth, there are problems with wetland plant diseases and insect pests, fires, their own growth cycle, and related maintenance, restoration and management; tenth, innovative applications in other fields, etc.

[0036] Since the proposal and development of artificial wetland technology is still relatively short, the technological development still cannot meet the current social needs. In the application of artificial wetlands, it mainly relies on experience, and there is a tendency to overly indulge natural conditions and ignore artificial enhancement, which affects the achievable treatment effects of different loads, such as: the best combination and three-dimensional intersection of aquatic plant species suitable for different regional conditions, the process of pretreatment, post-treatment, distribution, water collection, etc., the scientific configuration of bed materials, wetland structural types and alternating flow characteristics of submerged and surface water layers and their design theories and methods are rarely studied, lacking systematicity and integrity. In addition to the heavy nitrogen and phosphorus pollution, eutrophic water bodies also have prominent problems of hypoxia and algal bloom risks. Water aeration is an important means to solve underwater hypoxia; biological suspended matter such as algae blooms in water bodies and medium-sized aquatic animals in water bodies need to be intercepted, filtered or differentiated to escape protection during the in-situ treatment process. At present, such a complex, ecological and intelligent purification system has not been seen in the treatment of eutrophic water bodies.

[0037] In order to promote the management of eutrophication of water bodies and to more efficiently and practically manage the eutrophication problems or algal bloom risks in static water areas of aquatic ecosystems (lakes, rivers, reservoirs, etc.), the present invention introduces an artificial wetland treatment system using composite aeration-intelligent interception-vertical flow and a treatment and operation method thereof, which is a new in-situ long-term management technology, equipment and application of eutrophic water bodies in rivers and lakes.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Furthermore, the cabin body described in this embodiment is a hull structure with a water entry depth of 0.5m to 3m, and can be modified using a retired corrosion-resistant iron transport ship. The size of the cabin body is determined according to the area or water depth of the treated water area.

[0049] Furthermore, the water intake subsystem described in this embodiment is located on both sides outside the cabin body, and the water intake subsystem includes a submersible pump (the water intake depth is from the surface to 6m, adjustable) and a water intake pipe with a metering valve. The submersible pump is located on both sides outside the cabin body; one end of the water intake pipe is connected to the submersible pump, and the other end of the water intake pipe is connected to the filter scraper subsystem.

[0050] When working, the submersible pumps are arranged at both sides outside the cabin body and are located in the water area to be purified or the lake to be purified; through the operation of the submersible pumps, the sewage to be purified is extracted from the water area to be purified or the lake to be purified and flows into the filtering scraper subsystem through the water inlet pipe with a metering valve.
