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

Embodiment Construction

[0027] Such as figure 1 As shown, the high-voltage pulse discharge plasma water treatment device of the present invention includes a high-frequency high-voltage power supply 1, a reactor 2, a high-voltage electrode 3, a discharge medium 4, and a ground electrode 5;

[0028] The discharge medium 4 is arranged at the bottom of the reactor 2; the area of ​​the discharge medium 4 is slightly larger than the cross-sectional area of ​​the reactor 2. The thickness of the discharge medium 4 is 2-8 mm. The discharge medium 4 is silicone rubber.

[0029] The greater the thickness of the discharge medium 4, the higher the discharge voltage. The thickness of the discharge medium 4 is determined according to different sewage water quality and discharge voltage.

[0030] According to different properties of sewage, determine the required discharge voltage, and then determine the thickness of the discharge medium. For example, for high-concentration organic wastewater containing phenol, ...

Abstract

The invention discloses a water treatment device and method based on high-voltage impulse discharge plasma. 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, and the discharge medium is arranged at the bottom of the reactor; and the bottom of the discharge medium is provided with the ground electrode, and the ground electrode is grounded. By using the device, physical, chemical and microorganism pollutants and the like in water can be effectively removed, treatment cost is low, and especially, the removal effect of high-concentration organic matters in the water is obvious. According to the invention, when sewage treatment is carried out, a chemical reagent dose not need to be added; the treatment process is simple, has no wastes and secondary pollution, and is easy to automatically control; and energy consumption is greatly reduced while improving water treatment efficiency. The invention also discloses a water treatment method based on the high-voltage impulse discharge plasma.

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-voltage pulse discharge plasma water treatment method. 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 treatment. Contents of the invention [0003] The tec...
