Abstract
The invention provides a spiral piezoelectric electro-catalysis sewage treatment device. The spiral piezoelectric electro-catalysis sewage treatment device structurally comprises a water inlet system and a spiral piezoelectric electro-catalysis system, the spiral piezoelectric electro-catalysis system comprises a spiral pipeline and a piezoelectric film; a water outlet of the water inlet system communicates with a water inlet of the spiral pipeline, and the piezoelectric film is located in the spiral pipeline. A method for sewage treatment by using the spiral piezoelectric electro-catalysis sewage treatment device comprises the following steps: 1, sewage and wastewater enter the water tank through a water inlet of the water inlet system, are regulated to a proper flow speed through the flow regulating valve, and enter the spiral pipeline; 2, sewage and wastewater pass through the spiral pipeline under the action of gravitational potential energy, and the sewage and wastewater are in full contact with the piezoelectric film in the spiral pipeline; and 3, under the irradiation of an ultraviolet lamp tube, carrying out photocatalytic degradation reaction on the photocatalytic material on the piezoelectric film and pollutants in the sewage and wastewater. The piezoelectric effect of the material is excited by utilizing water flow potential energy, and the device has the advantages of energy conservation, environmental protection and easiness in implementation.
