Slide arc discharging plasma device for organic waste water treatment

Abstract

The organic waste water treating sliding arc discharge plasma apparatus includes forked knife-type electrode mounted on the insulating seat of the reaction hood and connected to high voltage power source, waste effluent collecting trough provided with atomizing nozzle, connected to the waste water trough and in the middle part of the insulating seat, reaction hood with gas sampling port, gas exhaust pipe, cooling water jacket around the gas exhaust pipe, compressed air pipe connected to the atomizing nozzle together with the waste water trough. Waste water and compressed air form waste water fog in the atomizing nozzle, and the air-water mixture pushes the arc formed in the arcing end downstream to generate sliding arc discharge and produce ozone, ultraviolet ray, high energy electron, electrolysis, OH, O and other active particles for on-line waste water treatment. The present invention has, especially, organic waste water treating capacity.

Description

Technical field [0001] The invention relates to a waste water treatment device, in particular to a sliding arc discharge plasma organic waste water treatment device. Background technique [0002] The treatment of organic wastewater, especially the treatment of high-concentration organic wastewater, is still a thorny problem, which plagues the chemical and pharmaceutical industries. There are many wastewater treatment methods in the prior art, and conventionally recommended biochemical methods, electrolysis methods and flocculation methods, etc. It is difficult to solve the problem of wastewater treatment containing complex organic matter, which is also an urgent problem to be solved in environmental protection. The research on the treatment of industrial wastewater by low-temperature plasma chemical method is not long in the world, and the methods that have been proposed include high-energy electron beam method and pulse discharge treatment method in water. Because the dens...

Problems solved by technology

[0003] Sliding arc discharge plasma is a new technology that has just emerged in recent years and has been applied to environmental protection technology. This method can generate non-equilibrium plasma at atmospheric pressure or higher pressure. In recent years, sliding arc discharge has been used abroad. Discharge Technology Governance H 2 S, SO 2 , N 2 O and other waste gas research reports, but there is no research or report on the use of sliding arc discharge to treat wastewater at home and abroad.
