Continuous catalytic plasma water pollution purification device

Abstract

The invention discloses a continuous catalytic plasma water pollution purification device which comprises a plasma discharge system, a reaction container and a stirrer arranged at the bottom of the reaction container, wherein the plasma discharge system comprises a high-frequency and high-voltage power supply, and a hollow electrode and a polar electrode which are respectively connected with a positive pole and a negative pole of the high-frequency and high-voltage power supply; the hollow electrode is used for matching with the discharge of the polar electrode arranged in the reaction container and filling the reaction container with gas; the reaction container is provided with an exhaust water inlet and a water outlet; the reaction container is internally provided with an air dispersion plate which is used for dispersing the gas in the reaction container; the reaction container is also internally provided with a microporous filtering membrane which is used for filtering the purified waste water and enabling the filtered waste water to be discharged outside through the water outlet. The whole device has the advantages of being stable and reliable in performances, simple in structure, high in practicality, good in treatment effect, high in energy utilization rate and handling capacity, and the like, thus being widely applied to the field of sewage treatment.

Description

technical field [0001] The invention belongs to the field of water pollution purification treatment, and in particular relates to a continuous catalytic plasma water pollution purification device. Background technique [0002] With the development of the economy, our country is currently facing the environmental problems of water shortage and serious water pollution. Traditional biological treatment technology is difficult to meet the increasingly complex water quality treatment requirements, such as the treatment of dye wastewater, pesticide wastewater, wastewater containing persistent organic pollutants, etc. [0003] Plasma technology is a relatively cutting-edge advanced oxidation technology that has emerged in recent years, and was first applied to environmental governance. It has multiple functions such as ozone oxidation, ultraviolet photodegradation, free radical oxidation, pyrolysis and high-energy electron radiation, and can effectively remove various pollutants i...
