specific Embodiment

[0032] A specific embodiment of the present invention is as follows:

[0033] The size of the reactor is 250×250×150mm, the reactor shell 1 is made of plexiglass, the barrier medium layer 2 is a quartz plate with a size of 150×150×3mm, the plate-type high-voltage electrode 3 and the plate-type ground electrode 4 are white steel plates, The size is 100×100×3mm, and the center of the plate-type high-voltage electrode 3 is welded with a stainless steel screw rod with a length of 100mm and a diameter of 6mm, which is used for a high-voltage high-frequency pulse power supply 8 . The suspension electrode 5 is a PVC mesh, which is laid on the surface of the solution to be treated, with a size of 240×240×1 mm, and a mesh size of 5×5 mm.

[0034] like figure 2 As shown, when a high-voltage high-frequency pulse voltage is applied between the two electrodes, a gas-liquid mixed discharge occurs in the reactor. There are a large number of discharge microfilaments in the discharge gap, fo...

Abstract

The invention discloses a dielectric barrier discharge water treatment device and a dielectric barrier discharge water treatment method. The dielectric barrier discharge water treatment device comprises a reactor shell, a barrier dielectric layer, a plate-type high voltage electrode, a plate-type grounding electrode, a suspension electrode and a high voltage and high frequency pulse power source.In the invention, a to-be-treated solution serves as the grounding electrode, and applies a high voltage and high frequency pulse voltage to the plate-type high voltage electrode so as to achieve thebreakdown of a barrier dielectric. With the assistant of the suspension electrode, the gas-liquid mixing dielectric barrier discharge is conducted between the to-be-treated solution and the barrier dielectric to produce more plasmas and further generate a large amount of active substances (such as -OH, O3, -O, H2O2 and the like), and the active substances react with organic substances in the to-be-treated solution to achieve the decomposing and completely-removing effects. The invention has the advantages that the gas-liquid mixing discharge is conducted in a highfield, so that the organic substances are effectively degraded, the problem that waste water cannot be sterilized, disinfected, decolorized and deodorized are effectively solved, and the more-effective and lower-cost indexes in ahigh voltage pulse water treatment technology are truly achieved.

Description

technical field [0001] The invention belongs to the technical field of low-temperature plasma generation technology and water treatment application, and relates to a high-voltage high-frequency pulse gas-liquid mixed medium barrier discharge plasma treatment device and method for wastewater. Background technique [0002] Water pollution is one of the urgent problems faced by all countries in the world, and its deterioration trend is getting worse and worse, making it difficult for traditional biochemical treatment technology to completely solve many problems of water pollution, such as denitrification and phosphorus removal, decolorization and deodorization, sterilization and microorganism removal. , degradation of persistent organic pollutants, etc. [0003] Treating wastewater with high-voltage pulsed dielectric barrier discharge plasma with electrodes embedded in liquid has important practical value as a more effective and lower-cost treatment technology. In this technol...
