Abstract

The invention belongs to the technical field of environmental engineering wastewater treatment, and relates to a plasma arc discharge catalytic water treatment method. The electrolyte is added to the aqueous solution to be treated at a certain concentration, and a pulsed direct current voltage is applied to the reaction system, so that the surface of the anode electrode can be restored to original state. The position generates a supported catalyst for discharge catalysis to achieve the purpose of degradation treatment of organic wastewater. The beneficial effect of the invention is that the discharge catalytic system has the characteristics of good synergistic effect, high energy efficiency of organic waste water degradation treatment, simple reactor design requirements, etc., and is a promising new water treatment technology.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering wastewater treatment and relates to underwater discharge catalysis. Background technique [0002] The discharge process can generate a high-energy environment, and the generated plasma contains a large number of high-energy active particles, which can damage many molecules. The combination of these high-energy active particles and catalysts can effectively improve the discharge treatment effect and promote the decomposition of organic molecules, so it has become a hot spot in the research and development of pollution treatment technology. [0003] Synergy of high-voltage pulse discharge and catalysis in the presence of volatile organic compounds, NO X Extensive research has been done in the field of gas purification [1-7] . However, there are few studies on the synergistic application of submerged discharge and catalysts in the field of water treatment. Domestic and foreign st...
