Method and device for removing bromate in water

[0028] Example 1: see figure 1 ,3 , Inside a closed 304# stainless steel tube 1 with an inner diameter of 123mm and a length of 1000mm, multiple KrCl with a wavelength of 222nm * Excimer lamp tube 2, the inner wall is polished into a mirror surface, the distance between the lamp tube and the inner wall of the lamp tube and the stainless steel tube cavity is not more than 15mm, the high-frequency high-voltage power supply for the excimer ultraviolet lamp 3, through the silicon rubber wire 4 directions The power supply of the molecular lamp 2 is 1400W. The treated water (drinking natural mineral water sterilized by ozone) enters from the inlet 5, and is discharged through the water outlet 6, with a flow rate of 100L/min. The bromate concentration before the detection treatment was 0.51mg/L, and the bromate concentration in the water after treatment was lower than the minimum detection limit of 0.005mg/L by the ion chromatographic detector used. It could not be detected, and the ozone still kept the required margin.

[0029] Embodiment 2: As in embodiment 1, the light source is KrBr with a wavelength of 207nm * Excimer lamp, the detection has similar results, and the ozone concentration is basically unchanged before and after treatment.

[0030] Embodiment 3: As in embodiment 1, the light source is KrBr with a wavelength of 190nm * Excimer lamp, the detection has similar results, and the ozone concentration is basically unchanged before and after treatment.
