Abstract

The invention discloses a dielectric barrier discharge pollutant treatment device based on a micro-gap channel. The dielectric barrier discharge pollutant treatment device is characterized by comprising a water tank, a gas plenum chamber and a micro-gap assembly, wherein a water tank water inlet is connected with a water inlet pipe, and a water tank water outlet is connected with a water outlet pipe; the water tank is grounded or a grounding electrode is arranged in the water tank; the gas plenum chamber comprises a high-voltage electrode and an insulating medium; the insulating medium is arranged in the gas plenum chamber; the high-voltage electrode is tightly attached to one side of the insulating medium; the micro-gap assembly is located between the water tank and the gas plenum chamber; the micro-gap assembly is made of an insulating material; and the water tank, the gas plenum chamber and the micro-gap assembly are connected through flanges. Self-cooling during discharging can beachieved, assembly arrangement is flexible, and degradation-resistant organic pollutants are efficiently treated.

Description

technical field [0001] The invention belongs to the technical field of pollutant treatment, in particular to a pollutant treatment device based on micro-slit channel dielectric barrier discharge. Background technique [0002] With the development of modern industry, a large amount of waste enters the water body, and some substances are difficult to biodegrade, such as: dimethylformamide (DMF), aniline, citric acid, pectin and other substances, causing water pollution. Conventional wastewater treatment technologies mainly include biological treatment, adsorption, extraction, neutralization and redox, etc., but these methods are not ideal for the treatment of refractory wastewater. [0003] Advanced oxidation technology uses various light, sound, magnetism and electricity to generate strong oxidizing free radicals, which are widely used in improving the quality of drinking water, pretreatment and advanced treatment of industrial wastewater, etc., in the treatment of refractory...
