According to the scheme, due to the adoption of the ultrasonic vibration plate, the generated ultrasonic waves can generate a mechanical effect, a cavitation effect, an acoustic flow effect and the like when being transmitted in liquid. The cavitation effect is the process of contraction, expansion and rupture of micro bubbles in the liquid. At the very short moment of micro bubble collapse, high temperature, high pressure, micro jets are generated within the bubble, accompanied by a strong shock wave. The micro jet flow and the shock wave spray water to the surface of the membrane of the precipitation device structure, the generated high-energy shock liquid repeatedly impacts the fouling attached to the surface of the membrane according to the layer to destroy the adsorption of the fouling and the surface of the membrane, and the fouling layer on the surface of the membrane falls off due to fatigue damage, so that the aim of cleaning is fulfilled. Meanwhile, when the ultrasonic wave is transmitted in the liquid, positive and negative alternating sound pressure can be generated, and the nonlinear effect can generate high-speed micro sound flow and sound flow on the interface of the liquid and the solid. On one hand: the micro-sound flow and the sound flow can bring new solution to the surface of the membrane to dissolve particles attached to the surface of the membrane, and meanwhile, cavitation erosion can remove insoluble particles on the surface of the membrane to reduce agglomeration of the particles on the surface of the membrane. On the other hand: the generation of micro-acoustic flow and acoustic flow can increase the stirring and diffusion effects, destroy pollutants, weaken or remove boundary sludge layers. The cleaning device adopts ultrasonic waves to carry out online cleaning, and cell walls of algae can be effectively destroyed under the action of the ultrasonic waves, so that algae breeding can be inhibited and eliminated.
