Dual channel discharge plasma device for treating water

Abstract

The invention discloses a dual channel device for treating aqueous discharge plasma, relating to the field of wastewater treatment. The device comprises a leakage transformer, a sink and an insulationboard arranged above the sink, one pair or more of electrodes are arranged on the insulation board, the horizontal distance between the discharging ends of each pair of electrodes is at least five times of the vertical distance between the discharging ends and the water surface, the high voltage output end of the leakage transformer is connected with each pair of electrodes, the water body beloweach pair of electrodes is a medium conductor, and the plasma is generated between the electrodes and the water surface.

Description

A dual-channel discharge plasma water treatment device technical field The invention relates to the field of wastewater treatment, in particular to a dual-channel discharge plasma water treatment device. Background technique The treatment of refractory toxic and harmful organic wastewater is a difficult point in environmental engineering. Advanced Oxidation Technology (AOPs) is a new water treatment technology emerging in the past 20 years. The characteristic of this type of technology is to oxidize and remove pollutants by stimulating the generation of hydroxyl radicals (·OH) in water. Such as the Fenton method, its typical reaction: Fe2++H2O2→Fe3++OH-+ OH; Fe3++H2O2→Fe2++HO2+H+. The organic pollutants are oxidized and degraded through the strong oxidation ability of OH to achieve the purpose of degrading sewage. However, this type of method has the following disadvantages: OH oxidation ability and selectivity are limited, water temperature, turbidity, pH, CO32- and ...

AI Technical Summary

Problems solved by technology

However, this type of method has the following disadvantages: OH oxidation ability and selectivity are limited, water temperature, turbidity, pH, CO32- and suspended solids interfere with the reaction, the processing cost is high, and there are unsafe and secondary problems in the storage and use of reagents. secondary pollution problem

Therefore, the equipment is complex and the electrodes need to be in direct contact with water mist, which is easily corroded, affects the life of the electrodes, and will cause secondary pollution of the water body
