WATER TREATMENT METHOD AND APPARATUS

摘要

PURPOSE:To enhance the utilization efficiency of electron beam by dissolving ozone or oxygen-containing gas in water to be treated under pressure and irradiating water to be treated with electron beam. CONSTITUTION:Water A to be treated is pressurized by a pump to be met with ozone or oxygen-containing gas in an ejector 1 and enters a pressure tank 3 through a line mixer 3. By the stagnation in the pressure tank 3, the dissolution of the gas is accelerated and the separation of excessive gas or the dissolved gas such as nitrogen gas in the water A to be treated is performed. Thereafter, the water A to be treated having ozone or oxygen dissolved therein is sent to a reactor 7 to be sprayed from a nozzle 6 herein in a filmy state and irradiated with electron beam from an electron beam accelerator 8 to subject the org. substance dissolved in the water A to be treated to decomposition treatment while the treated water is discharged from a pipe 17. By this method, the utilization efficiency of electron beam can be enhanced.
