Background Along with the increasing serious problem of eutrophication of water bodies, the outbreak of water bloom becomes a global environmental problem, particularly, blue algae bloom not only affects the water body landscape, but also can generate harmful substances such as microcystin and the like, and the water bloom forms a serious threat to the water ecological system and human health. At present, the control method for algae in water mainly comprises a physical method, a chemical method, a biological method and the like. Among the physical control methods, mechanical salvage is the most direct treatment means, but has limited treatment effect on small algae. In recent years, the electromagnetic wave technology has good application prospect in the field of water algae control.

CN221296504U proposes a low-frequency electromagnetic wave purifying device comprising a control host, a first electromagnetic wave emitter and a second electromagnetic wave emitter, wherein ions in water are accelerated to move by low-frequency electromagnetic waves, thereby inhibiting the growth of bacteria and algae [2]. In terms of mobile algae control equipment, CN222005313U discloses an unmanned blue algae treatment vessel, which comprises a vessel body, a central control cabinet and a blue algae treatment device, wherein blue algae is dispersed by vibration of an ultrasonic transmitter, and the biological function of the algae is destroyed by transmitting low-frequency electromagnetic waves by a low-frequency wave generator [3].

CN210457571U describes an algae controller comprising an electromagnetic wave generator disposed in a housing capable of removing harmful algae and microcystins from 0-1 meter below the water [5].

The method has obvious technical defects that firstly, the electrodes are easy to generate electrochemical corrosion or passivation in water for a long time to shorten service life, secondly, effective current can be formed only by relying on the conductivity of the water body, the effect is poor in the water body with low conductivity, and thirdly, if the electrode distance is reduced for improving the field intensity, the exposed electrodes are easy to be short-circuited by impurities in the water to burn a circuit. The prior art does not solve the problem of how to apply high-density current to water under the condition of electrode insulation, and finally, the prior electromagnetic wave treatment technology mostly adopts fixed equipment or a simple floating device, lacks intelligent autonomous navigation capability and accurate algae control mechanism, and cannot realize high-efficiency treatment of large-area water areas. Particularly in the aspect of accurate control of key parameters such as treatment frequency, voltage difference, current density and the like, the prior art does not form a solution of a system, and effective regulation and control of algae characteristics under different water conditions are difficult.
