AI Technical Summary

Technical Problem

The volume of the catalytic chamber in traditional low-temperature plasma water treatment devices cannot be flexibly adjusted, resulting in poor performance when treating wastewater with different COD concentrations and high operating costs.

Method used

A low-temperature plasma water treatment device is designed, which adopts a triangular electrode column and an annular electrode plate structure, combined with an extrusion component and an oxygenation component. By adjusting the cross-section of the water flow channel and the oxygen release, and with the help of the plasma catalyst on the insulating catalyst plate, the electric field strength and oxidation rate can be adjusted.

Benefits of technology

It improves the efficiency and effectiveness of wastewater treatment, reduces operating costs, adapts to wastewater treatment needs with different COD concentrations, and enhances purification rate and effect.
