Abstract

The invention discloses a pollutant treatment device utilizing foam dielectric barrier discharge plasma. The pollutant treatment device is characterized in that the device comprises a water tank and adischarge assembly; a material feed of the device enters the device in the form of a gas-liquid mixture; the discharge assembly comprises a high-voltage electrode, insulating media and an aeration disc (a micro-pore channel element); the insulating media are arranged in the water tank, the medium 1 is fixed through a base, and the medium 2 is tightly attached and fixed to the medium 1; the high-voltage electrode and the ground electrode are located between the insulating medium 1 and the insulating medium 2 respectively; the electrode is tightly attached between the two insulating media; theaeration disc is located between two electrode assemblies; the surface of the aeration disc is close to the medium 2; and gas and liquid on the surface of the aeration disc uniformly flow out when a gas-liquid mixture is introduced. According to the device, self-cooling during discharging can be realized, and degradation-resistant organic pollutants can be treated with a low cost and a high efficiency.

Description

technical field [0001] The invention belongs to the technical field of pollutant treatment, in particular to a pollutant treatment device for foam 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...
