An immersed plate discharge plasma sewage treatment device

Abstract

The invention discloses a submerged plate-plate discharge plasma sewage treatment device, which comprises a reaction vessel, a gas circulation pump and a discharge protection cover arranged in the reaction vessel. Electrode plates, the discharge electrode plates are respectively connected to the ends of the positive pole and the negative pole, and the other ends of the positive pole and the negative pole are respectively connected to the positive and negative poles of the high-frequency high-voltage power supply through the positive pole protection tube and the negative pole protection tube, One end of the positive electrode protection tube and the negative electrode protection tube are respectively connected to the discharge protection cover, and the other ends of the positive electrode protection tube and the negative electrode protection tube are closed and arranged outside the reaction vessel, and the discharge protection cover is provided with Aeration holes. The treatment device has the advantages of simple operation, low cost, wide application range, stable treatment effect, no secondary pollution, etc., and has a remarkable degradation effect on refractory organic pollutants.

Description

technical field [0001] The invention belongs to the field of water treatment and purification treatment, and mainly relates to a submerged plate discharge plasma sewage treatment device. Background technique [0002] With the continuous development of economy and society, the environmental problems of water bodies have become increasingly serious. Many refractory pollutants are discharged into water bodies, resulting in the accumulation of these substances in water bodies, which seriously threatens aquatic ecosystems and human health. 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 s...

AI Technical Summary

Problems solved by technology

[0004] Most of the plasma sewage treatment devices currently developed have some problems more or less, such as the inability to discharge efficiently in the water phase, and the inability to efficiently generate plasma. The body cannot be fully utilized, and cannot be fully mixed and reacted with the water body in time; in addition, the ozone generated during the plasma discharge process cannot be fully utilized, and is discharged into the air to pollute the environment; some other reaction devices require magnetic stirring or mechanical stirring, which consumes energy bigger
