A method and device for treating water body pollution

The invention relates to a device and method for treating water body pollution. The device includes a first processor, a signal pre-processing apparatus, a signal processing recorder, a second processor, a signal storage replayer and a microamp programmable power supply. The first processor is connected to the signal pre-processing apparatus. The signal pre-processing apparatus is connected to the signal processing recorder. The second processor is connected to the signal storage replayer. The signal storage replayer is connected to the microamp programmable power supply. The method is economical, efficient, free of secondary pollution, capable of comprehensively restoring a sealed water body and an open type water body, shorter in purification time than other water treatment manners and lower in cost. In a water body treatment process, no additive is added, discharging is not performed on the water body, no secondary pollution is generated, and adverse effects on aquatic organisms and humans are not generate
