Abstract
The invention relates to an ozone oxidation water treatment device which essentially consists of an oxygen cylinder, an ozonation reactor, a high voltage power supply, a water storage tank, a water pump and an ozone destruction device. The pressure oxygen in the oxygen cylinder generates ozone and living radicals in the air chamber of the ozonation reactor under the function of a high voltage electric field; the ozone and the living radicals instantly go through a micro-hole ceramic pipe and generate micro bubbles in an ozonation reaction chamber, react quickly with water or wastewater pumped in; the time interval between the two technique processes of the generation and absorption of ozone is reduced and living radicals generated in a corona discharge zone are utilized to be involved in the reaction of oxidizing pollutants in water highly efficiently. The device improves ozone transfer and oxidation rate and saves ozonation operation cost.
