Abstract

The invention discloses a pollutant processing device based on dielectric barrier discharge plasma. The pollutant processing device is characterized by comprising a water tank and a discharge component, wherein the water inlet of the water tank is connected with a water feeding pipe; the water outlet of the water tank is connected with a water discharging pipe; the discharge component comprises ahigh-voltage electrode, insulating media, a micro-channel element and an insulating ring; the water tank is earthed, or an earthing electrode is arranged in the water tank; the insulating media are arranged on the bottom in the water tank; the high-voltage electrode is tightly attached to the lower side of the insulating media; the insulating ring is near or is tightly attached to the upper side of the insulating media; the micro-channel element is positioned in the insulating ring, is provided with a plurality of micropores, and is made of insulating materials. According to the pollutant processing device disclosed by the invention, self temperature reduction and cooling during discharge can be realized, and meanwhile, refractory organic pollutants can be efficiently processed at low cost.

Description

technical field [0001] The invention belongs to the technical field of pollutant treatment, in particular to a pollutant treatment device based on dielectric barrier discharge plasma. Background technique [0002] With the development of petrochemical, organic synthesis, printing and dyeing and other industries, various high-concentration refractory organic wastewater and waste gas have increased correspondingly, posing more problems for environmental protection. The treatment of refractory organic pollutants has always been a difficulty and focus in environmental protection. Refractory organic matter refers to compounds that cannot be biodegraded, or cannot be degraded at a fast enough rate in any environment, so that they accumulate in the environment for a long time. This type of organic matter has the characteristics of easy bioaccumulation, serious environmental pollution, and great harm to human body. Common refractory organic pollutants include heterocyclic compounds...
