Description
The utility model relates to the quality purifying device for water that can be used for tap water, micro-polluted water matter, water source water purification, sterilization and eliminate organic pollutant.
Photocatalysis oxidation technique is through in the last thirty years research and development, but the commercial applications in the purifying treatment aqueous systems is made slow progress, major cause is: (1) is in the real reaction process, the main oxides kind photohole life-span is short, hole and electronics are very easily compound, have limited light-catalyzed reaction speed greatly; (2) existence of dissolving transition metal and salt produces detrimentally affect to the light-catalyzed reaction process in most of water bodys.
Task of the present utility model is the problem that exists at existing light catalytic purifying water quality, proposes a kind of photoelectrocatalysis water purifier that can improve water quality processing speed and effect.
The technical solution of the utility model is based on the photoelectrocatalysis principle and the photoelectrocatalysis water purifier that proposes, its basic structure is, middle shaft position at a barrel reactor housing is provided with a ultraviolet lamp tube, this ultraviolet lamp tube is enclosed among the quartz glass sleeve, the TiO of suit one basic one-tenth tubular outside quartz glass sleeve
2Optoelectronic pole, the TiO of said tubular
2Have limbers or water stream channel on the barrel of optoelectronic pole, at TiO
2The outside of optoelectronic pole is positioned at its axis both sides and is respectively equipped with a negative electrode and a reference electrode, by a potentiostat to TiO
2Optoelectronic pole, negative electrode and reference electrode provide corresponding bias potential, make TiO
2Form potential difference between optoelectronic pole and the negative electrode.

2Film constitutes.Said TiO
2Can ooze assorted Fe, Ze, WO in the film
3Or SiO
2, to increase TiO
2The activity of optoelectronic pole.Its preparation method can adopt conventional sol-gel method to make TiO
2Colloidal sol can ooze assorted Fe, Ze, WO in colloidal sol
3Or SiO
2, adopt again dipping-pulling method with sol impregnation on optoelectronic pole tubular matrix, after high-temperature roasting, make again.
The barrel of said tubular matrix should have limbers or water stream channel, for example can be reticulated structure.
