| 摘要 |
The present invention relates to a slim-type plasma advanced water treatment apparatus including an inner pipe (11) where a first communication path (11A) is formed for the passage of treatment target water, an outer pipe (12) that is externally capsulated in the inner pipe (11) and has a second communication path (12A) for the passage of gas for a radical reaction, plasma generating means that includes first and second electrodes (21, 22) respectively arranged in the first and second communication paths (11A, 12A) and a plasma power supply unit connected to the first and second electrodes (21, 22), a pair of caps (13) that block both ends of the inner pipe (11) and the outer pipe (12), a first inlet (11b) that communicates with the first communication path (11A) and receives the inflow of the treatment target water, a first outlet (11c) through which the treatment target water flows out after inflow through the first inlet (11b) and passage through the first communication path (11A), a second inlet (12b) that is connected to an air supply source (AS) providing the gas for a radical reaction, and a second outlet (12c) through which a radial generation source generated by plasma discharge of the gas for a radical reaction flowing in through the second inlet (12b) is discharged, in which the inner pipe (11) and the outer pipe (12) maintain a gap of 2 to 10 mm. According to the present invention, ozone yield can be improved. |
