Dielectric barrier discharge water treatment device and method

Abstract

The invention provides a dielectric barrier discharge water treatment device and method, belonging to the technical field of a water treatment device and method. The device comprises a high-voltage high-frequency pulse power supply, a reactor shell, a column high-voltage electrode, a cylindrical submerged low-voltage electrode, a vermiculite-supported titanium dioxide catalyst, a dielectric barrier layer and a microporous aeration membrane. The method comprises the following steps: adding a solution to be treated, and applying a high-voltage pulse voltage between the column high-voltage electrode and the cylindrical submerged low-voltage electrode, wherein the peak voltage is 1-100kV, and the frequency is 1-50KHz; and adjusting the inlet air quantity, and regulating the contact time between treated wastewater and active particles inside the reactor. An aerator is introduced into the water treatment device, and medium-activity substances generated by dielectric barrier plasma discharge can completely enter the solution to the treated through the aerator, so the water treatment device has the advantages of high mass-transfer efficiency and short required time; the method is stable in running and simple to operate, and can run under atmospheric pressure; and the equipment is easy to manage and has high practicality and economical efficiency.
