Wastewater treatment device based on water drop electrification

The invention discloses a wastewater treatment device based on water drop electrification. The wastewater treatment device comprises a Kelvin water drop and a high-voltage electric field water treatment module, and can also form a wastewater treatment device with water circulation and a wastewater treatment device with a cascade structure. Effective anti-fouling and sterilization treatment on wastewater is realized through manners including influences on water molecule arrangement by a high-voltage electric field of a high-voltage electric field water treatment module, generation of active oxygen radicals and the like; the source of a static electric field of the high-voltage electric field water treatment module is charge accumulation generated by the Kelvin water drop through the water drop electrification and an additional high-voltage source is not needed; and additional energy input is hardly needed, so that the wastewater treatment device is a novel pollution-free and low-energy-consumption wastewater t
