Technical field
The utility model relates to a kind of free radical generating unit, particularly relate to a kind of in field of waste water treatment plasma body hydroxyl radical free radical generating unit.
Technical background
DBD is that the English of dielectric barrier discharge (Dielectric Barrier Discharges) is write a Chinese character in simplified form, and cries silent discharge again, is a kind of typical nonequilibrium state AC gas discharge.DBD is a kind of reliable, economic method that produces the normal atmosphere nonequilibrium plasma, so be widely used in that ozone is synthetic, high-power purple reaches fields such as vacuum ultraviolet light source, water treatment and environment protection outward.
The elementide material that hydroxyl is made up of the hydrogen-oxygen atom has extremely strong oxidation capacity.The characteristics of hydroxyl radical free radical are strong oxidizer (E
0=+2.80V): the chemical reaction of participation belongs to free radical reaction, and speed is exceedingly fast; Residual hydroxyl final production thing is O
2, H
2O.Because hydroxyl has extremely strong oxidation capacity, dosing is low; Belong to free radical reaction with the chemical reaction of microorganisms such as bacterium, algae, the speed of response of killing microorganisms is exceedingly fast; Residual hydroxyl final production thing is O
2, H
2There are not problems such as poisonous residue in O.Therefore, obtaining of hydroxyl radical free radical is a kind of Perfected process that can be used for administering aspects such as red tide, water ballast, sewage recycling.
