The thickness of the immersion sleeve 4 ensures that the ultraviolet intensity remains above 90% after penetration. The shape and specifications of the immersion sleeve 4 are determined by the internal structure of the enclosed ultraviolet LED light-emitting unit 3, micro-nano aeration unit, algae detection unit, battery, adapter, wireless module, and intelligent processor.

Adapt to the characteristics of the water body in which it is located and obtain more optimal parameters; when determining the operating parameters of other units, the intelligent processor gives priority to executing the commands of the remote control signal. When the relevant commands of the remote control signal are defaulted, it automatically selects the parameters calculated by it for execution; when there are a large number of such structures in the same water body, the server terminal can send a combined remote control signal to the intelligent processors of all structures through the wireless module to achieve the optimal combination effect of multiple intelligent bodies; its shape specifications and algorithm programs include various types commonly available on the market, and models that comply with "Information Technology Vocabulary Part 11: Processors" (GB / T5271.11-2000) and can be assembled in this embodiment can all be used as intelligent processors, such as but not limited to models such as TX 7400.

[0047] Example 2

[0048] This embodiment discloses an algae removal and odor suppression device, comprising several algae removal and odor suppression structures of the first embodiment, wherein adjacent algae removal and odor suppression structures are in contact with each other. Figures 5a to 5fAs shown, a large number of algae-removing and odor-reducing structures cover the surface of the water body, closely spaced together, with little sunlight reaching below the water surface. After the algal bloom is eliminated and the structures are recovered, they undergo inspection and repair before being stored and awaiting their next use. The structures can be connected by ropes and connectors to form a string or net-like arrangement. During use, they can be dropped into the water in a cluster and then retrieved using ropes. If the structures are not connected, they can be dropped into the water one by one during use and collected by netting.

[0049] When algae, especially cyanobacteria, in the water body burst or are about to burst to a high biomass, depending on the degree of algal bloom and the area of ​​the water body, dozens to hundreds of these structures are deployed into lakes, reservoirs, river dams, offshore, waterscapes, or water plant raw water inlet and storage structures. A large number of these structures are laid flat on the surface of the water body in a certain arrangement to block the sunlight from entering the entire water surface, creating light-isolating conditions to inhibit algae growth. At the same time, solar energy is used to drive the structures into working state to accurately remove algae and suppress odor. After the algal bloom is eliminated, all structures can be recovered and reused by salvaging, towing, etc. During normal operation, the buoy-shaped shell 2 makes the entire structure float on the water in the form of a buoy; the submerged sleeve 4 wraps the ultraviolet LED light-emitting unit 3, the micro-nano aeration unit and the algae detection unit to protect these submerged modules and units; the solar panel 1 receives sunlight radiation to drive the entire structure; the battery remains charged during the day and provides energy at night when the amount of sunlight is insufficient; the adapter performs output conversion so that the output of the solar panel 1 and the battery is converted to a rated working input state that can meet the requirements of other working units; the wireless module uploads the working status of the structure around the clock, and at the same time receives the remote control signal online and transmits it to the intelligent processor; the intelligent processor responds to the remote control signal according to the remote control signal. The system calculates and analyzes the actual conditions of the water body and the number of algae, using a built-in complex algorithm, and intelligently adjusts the operating parameters of other working units. The submerged algae detection unit measures absorbance (OD680) at 680nm in real time, characterizing the density of algae in the water for calculation by the intelligent processor. The micro-nano aeration unit receives control signals from the intelligent processor and delivers varying intensities of micro-nano aeration to the surrounding water, improving hydraulic conditions and breaking up and destabilizing algae clusters. The UV LED light-emitting unit 3 receives control signals from the intelligent processor and emits UV radiation of a specific wavelength, calculated based on the calculation, toward the surrounding algae clusters to remove algae and suppress odor. The structural assembly and use improves the ease of engineering application; the structure forms an intelligent system, enhancing precision processing capabilities. The structural application method combines the principles of physical isolation (blocking algae photosynthesis by sunlight), micro-nano aeration (breaking up algae clusters by micro-nano aeration), and UV algae cell removal to kill over 90% of algae cells and effectively inhibit their resurgence. This invention can effectively eliminate algae pollution, reduce the pressure of algae cell removal during water treatment, and effectively improve safety and security in ecological, water supply, and landscape aspects.

[0050] This embodiment deploys and intelligently dispatches a large number of algae removal and odor suppression structures, collects and utilizes the characteristics of algae in the actual water body in real time, and adopts an intelligent processing algorithm to control the micro-nano aeration unit and the ultraviolet LED unit to accurately remove algae and suppress odor. The assembled method is used to improve the convenience of engineering applications; an intelligent system is formed to enhance the precision processing capability; and the principles of physical isolation of sunlight to block algae photosynthesis, micro-nano aeration to break up algae clusters, and ultraviolet algae cell removal are used as application methods to achieve efficient elimination of algae pollution, reduce the pressure of algae cell removal in the water treatment process, and effectively improve the safety level in ecology, water supply, landscape, etc.

[0051] This embodiment has the following advantages: (1) It isolates sunlight and interrupts algae photosynthesis on a large scale. A large number of such structures cover the surface of the water body, with each one closely adjacent to the other, so that almost no sunlight can penetrate below the water surface. The structures can be connected by ropes to form a string or a net, and when in use, they are collectively dropped into the water. When recovered, the large number of structures can be pulled back by ropes. The structures can also be unconnected and dropped into the water one by one when in use. When recovered, they can be collected by casting a net. After the algae bloom is eliminated, the structures can be recovered, inspected and repaired, and then stored for the next use.

[0052] (2) Accurately detect algae pollution in real time and understand algae characteristics. In this invention, the structure is equipped with a portable spectrophotometer to measure the absorbance OD680 of algae at 680nm in real time in situ, characterize the density of algae in the water, and use it as an algae characteristic for intelligent calculation to ensure that the treatment parameters are consistent with the current characteristics of the water body.

[0053] (3) The processing technology is highly intelligent and accurate. The structure calculates according to the algorithm to obtain operating parameters that meet the current working conditions. At the same time, it also has a built-in machine learning algorithm program to record and learn the effects of the "detection-processing-detection" process of the water body. It continuously fine-tunes the calculation results of the established algorithm, constantly adapts to the characteristics of the water body, obtains better parameters, and can also achieve the optimal combination effect of multiple intelligent agents.

[0054] (4) To prevent high algae concentrations from blocking UV penetration, micro-nano aeration is used to improve hydraulic conditions. In this invention, the structure delivers micro-nano aeration of varying intensities to the surrounding water, improving surrounding hydraulic conditions, breaking up and destabilizing surrounding algae clusters, and enhancing UV penetration for deep algae removal.

[0055] (5) Avoid mercury leakage risk and improve energy efficiency. Utilizing the material properties of AlGaN ternary alloy, the lamp beads of various wavelengths of UV LEDs are assembled to not only avoid the mercury leakage risk of traditional UV mercury lamps, but also improve energy efficiency and achieve efficient algae removal.
