Water treatment device based on high-voltage impulse discharge plasmas and high-frequency high-voltage power supply thereof

Abstract

The invention discloses a water treatment device based on high-voltage impulse discharge plasmas. The device comprises a high-frequency high-voltage power supply, a reactor, a high-voltage electrode, a discharge medium and a ground electrode, wherein the high-frequency high-voltage power supply is connected with the high-voltage electrode; the high-voltage electrode is fixedly arranged in the reactor; the discharge medium is arranged at the bottom of the reactor; the bottom of the discharge medium is provided with the ground electrode; and the ground electrode is grounded. By the device, physical, chemical and microbic pollutants and the like which are contained in the water are effectively removed, the treatment cost is low, and especially, the removal effect on high-concentration organic matters in the water is obvious. When the device is used for treating sewage, a chemical reagent dose not need to be added, the treatment process is simple, no waste and secondary pollution are generated, simultaneously, automatic control is easy to realize, and the energy consumption is greatly reduced while the water treatment efficiency is improved. The invention also discloses a high-frequency high-voltage power supply for the water treatment device based on the high-voltage impulse discharge plasmas.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a high-voltage pulse discharge plasma water treatment device. The invention also relates to a high-frequency and high-voltage power supply for a high-voltage pulse discharge plasma water treatment device. Background technique [0002] Most of the existing methods and technologies for using discharge plasma to treat sewage or disinfect and sterilize drinking water use the method of generating plasma by discharging in the gas first, and then filling the gas containing ozone into the water. . Due to the short life of most active particles in the discharge gas, its oxidation cannot be fully utilized; in addition, in these methods, the discharge voltage is not applied to the water, and the high voltage has no effect on the activation, polarization and neutralization of impurities in the water. Does not have a great impact, which leads to the inefficiency of these methods for water treat...

Problems solved by technology

Due to the short life of most active particles in the discharge gas, its oxidation cannot be fully utilized; in addition, in these methods, the discharge voltage is not applied to the water, and the high voltage has no effect on the activation, polarization and neutralization of impurities in the water. Does not have much impact, resulting in inefficient water treatment by these methods
