An underwater pulse rotating sliding arc low temperature plasma sewage treatment device

Abstract

The invention discloses an underwater pulsed rotating gliding arc low-temperature plasma sewage treatment device which comprises a novel plasma generation system, high-voltage pulse and a high-efficiency reactor and can effectively solve the critical technical problem of underwater large-area discharge, realize mass transfer optimization from active substances to wastewater molecules and the full and effective utilization of energy through effective gas-liquid two-phase discharge, and can be widely applied to industrial wastewater treatment. The invention further discloses a sewage treatment method based on the sewage plasma treatment device; an electrode is driven by a speed-adjusting motor to rotate so as to generate large-scale underwater glide arc discharge. The plasma treatment device and the sewage treatment method disclosed by the invention can effectively remove difficult-to-degrade matters in the industrial wastewater and have the advantages of being quick in degradation rate, wide in treatment scope, good in effect, free from secondary pollution and the like.

Description

technical field [0001] The invention discloses an underwater pulse rotating sliding arc low-temperature plasma sewage treatment device, which relates to the technical field of low-temperature plasma sewage treatment. Background technique [0002] With the acceleration of urbanization and the advancement of science and technology in our country, the indiscriminate discharge of industry and agriculture, and the rapid increase of sewage discharge, water pollution has become one of the major issues that have attracted worldwide attention. For these pollutants, commonly used wastewater treatment methods mainly include biological methods, physicochemical methods, and oxidation methods, but these methods are not effective for high-concentration, refractory high-molecular organic matter. In response to the problems in wastewater, some new wastewater treatment technologies have been developed in the past two decades, such as oxidative flocculation, photocatalytic degradation, heterog...
