Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] As shown in Figures 2 and 3, the electrodeless discharge pulse plasma liquid-gas discharge device for wastewater treatment includes a high-voltage pulse power supply 12, a plate electrode 7, a plate electrode 8, an electrode support 9, an electrode support 10 and an insulating plate 14 The discharge vessel 11. The discharge vessel 11 is an insulating box, the insulating box is a cylinder with a diameter of 45 mm, the insulating plate 14 is a ceramic plate, the electrode support 9 and the electrode support 10 are two metal rods, and the plate electrode 7 and the plate electrode 8 with a diameter of 40 mm pass through the The two metal rods described above are horizontally fixed above and below the insulating plate 14 in the insulating box. One or more small holes 13 of 0.5-3 mm are opened on the insulating plate 14 , and the insulating pl...

Abstract

A non-polarized discharge liquid treating device and treatment are disclosed. Plated electrode (7) and plated electrode (8) are discharging in liquid-phase, gas-liquid phase or gas-liquid mixed phase to realize high-voltage discharging plasma by high-voltage pulse or DC, heat-resistant insulating board (14) with hole (13) focuses electric field to locality, which makes local electric filed a certain height. It can realize plasma discharge, produce shock wave, ultraviolet ray and various active free radicals and remove various pollutants effectively. It's efficient and has no electrode melt.

Description

technical field [0001] The invention belongs to the field of low-temperature plasma technology and water treatment technology, and relates to a method and a device for treating wastewater with high-voltage pulse discharge plasma. Background technique [0002] With the increasingly serious pollution and the further development of the deterioration of water environment quality, traditional water treatment methods are faced with more severe challenges, especially many water environmental pollution problems that are difficult to solve with traditional chemistry-biology, such as dephosphorization, denitrification, and deodorization. , decolorization, sterilization, removal of trace pollutants such as dioxins. At present, it is very important to use pulsed discharge plasma technology combined with highly active chemical free radicals generated by ultraviolet light to carry out chemical reactions for sewage treatment. [0003] Discharge sewage treatment technology in liquid is the...
