[0027] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0029] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0030] The eutrophication process of rivers, lakes, estuaries and offshore areas will lead to the massive reproduction of algae and the formation of water blooms. Common dominant species of water blooms include microalgae such as cyanobacteria, green algae, and diatoms. Studies have shown that the frequency of water bloom events has increased worldwide, the scale of impact has expanded, and the duration has become longer and longer. Blue algae cover the water surface through abnormal proliferation, deteriorating water quality, emitting odors, reducing dissolved oxygen, and releasing algal toxins, which seriously damages the function of the ecosystem and poses a huge threat to drinking water safety and human health. Therefore, controlling and managing blue algae blooms is a difficult problem that urgently needs to be solved in the ecological management of rivers, lakes and reservoirs.

[0031] In the related technology, cyanobacteria can generally be treated with ultrasound, mainly by utilizing the various effects produced during the propagation of ultrasound in water (such as cavitation effect, mechanical effect and free radical oxidation effect, etc.) to destroy the pseudo-cavitation cells of cyanobacterial cells, causing them to lose buoyancy and sink, thereby inhibiting photosynthesis and ultimately leading to apoptosis of algae. Pseudo-cavitation cells are gas-containing air sacs in cyanobacterial cells that can provide buoyancy for the cells.

[0032] Ultrasonic cavitation refers to the phenomenon that strong ultrasonic waves are emitted to generate bubbles of dissolved gas or liquid vapor in liquid, which grow, explode and disappear. Generally speaking, pure liquid molecules have strong binding force and thus have extremely high tensile strength. However, some tiny bubbles are mixed into the actual liquid for various reasons, which constitute the weak links of the liquid. When the negative pressure phase formed by the alternating sound pressure is strong enough, the liquid will first be pulled apart at these weak links, thereby forming a cavity and growing; then, under the action of the positive pressure that follows, the cavity will be compressed and then quickly closed. The process in which these tiny bubbles quickly shrink, close and rupture with ultrasonic vibration is called ultrasonic cavitation.

[0033] In response to the above problems, the embodiments of the present application provide a cyanobacteria bloom treatment vessel and treatment method, which can detect the growth period of cyanobacteria in water areas, and adjust the working mode of the ultrasonic transducer in real time according to the different growth periods of cyanobacteria, and can adjust the underwater depth and angle of the ultrasonic transducer, which is conducive to better controlling the number of cyanobacteria and improving the water quality in water areas.
