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

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.
