Embodiment 1

[0041] Embodiment 1, domestic sewage treatment

[0042] Pass domestic sewage with influent COD ≥ 350mg / L into the plasma reactor 3; connect the gas source 4 of the plasma reactor 3; connect the power supply 1 of the plasma reactor 3, and the plasma reactor 3 generates plasma Body, using plasma to treat domestic sewage; discharge the treated water. After testing by conventional methods, the treated effluent COD<5mg / L.

Embodiment 2

[0043] Embodiment 2, fermented sewage

[0044] Step is with embodiment 1, and parameter is as follows:

[0045] Influent COD>18179mg / L, SO 4 2- >6800mg / L, NH 3 -N>2149mg / L

[0046] After treatment, the effluent COD≤356mg / L, SO 4 2- 3 -N<78mg / L

Embodiment 3

[0047] Embodiment 3, chemical fiber sewage

[0048] Step is with embodiment 1, and parameter is as follows:

[0049] Influent COD>4500mg / L

[0050] Effluent COD<200mg / L after treatment

Abstract

The invention relates to a plasma water treatment method and a device thereof. The plasma water treatment method comprises the following steps: the water to be treated is communicated into a plasma reactor; the air supply of the plasma reactor is switched on; the power supply of the plasma reactor is switched on, the plasma reactor generates plasma by which the water is treated; and the treated water is discharged. The plasma water treatment device comprises the plasma reactor, a water inlet opening and a water outlet opening which are arranged on the plasma reactor, and at least a pair of plasma arc discharge guns which are oppositely arranged and connected with the air supply and the power supply. The invention provides the plasma water treatment method which can consecutively generate the plasma with high efficiency, and provides the plasma water treatment device with simple structure.

Description

technical field [0001] The invention relates to a water treatment method and a device thereof, in particular to a method and a device for treating drinking water and sewage with plasma. Background technique [0002] With the development of industry and the improvement of living standards, various industrial sewage and domestic sewage have emerged. If these sewage are discharged directly without treatment, they will pollute water bodies such as rivers, lakes and seas. Among them, toxic and harmful organic sewage and sewage with high concentration of heavy metal ions are difficult to be treated by conventional sewage treatment methods. [0003] At present, ozone is usually used to treat high-concentration organic sewage. The method is to introduce the ozone generated by the ozone generator into the sewage through the pipeline to treat the sewage. The problem of this method is that the life of ozone is short, and the contact between ozone and sewage is insufficient, which lea...
