<p>In an ozone reactor of a conventional drinking water treatment apparatus, since the optimum discharge pressure of an ozone generator is used, it required long time for purifying processing water with ozone gas. In the invention, ozone gas in an ozone generator 1 is stored in an ozone gas compressor 5 and thereafter compressed, injected into an ozone reactor 6, and immediately pressurised by a processing water pressuriser 8, thus quickly promoting oxidation by ozone. As a result, since processing water and ozone in the ozone reactor are pressurised, the oxidation rate increases, the time for purifying the processing water can be shortened as compared with an arrangement without processing water pressuriser, and the ozone reactor can be miniaturised. <IMAGE></p> |
