Piece -52, dissolved oxygen sensing membrane -53, optical filter -54, photodetector -55；The higher source luminance includes blue-ray LED, red-light LED
And white light；The photodetector is electrically connected with processor；The optical lens group eyeglass is 3~6；The slide is new
Type customizes slide, and the slide is provided with the groove supporting with dissolved oxygen sensor size.
7. low stain water restoration and treatment device according to claim 6, it is characterised in that described based on the oxygen sensing film
The composition and preparation process of the dissolved oxygen sensing membrane of sensor, comprise the following steps：
(1) appropriate tetraethoxysilane and trifluoro propyl trimethoxy silane addition round-bottomed flask is weighed, then continues to add
Deionized water and absolute ethyl alcohol, then using hydrochloric acid as catalyst, adjust pH2.0-3.5, after sealing magnetic agitation 2 hours；
(2) fluorescence indicator ethanol solution, ultrasonic agitation 30 minutes are added；
(3) 0.2 ‰ -0.08 ‰ active carbon nanoparticles particles are added, ultrasonic agitation 50 minutes is put under light protected environment normal temperature and is aged 48
Hour；
(4) sol evenning machine is used in the cover glass groove anticipated, to obtain aged rear colloidal sol spin coating 3000r/min, 30s
Dissolving the oxygen sensing film need in the dark at least dry 7 days after it is standby.
(5) cover glass is activated 24 hours need to be immersed in before 0.05M NaOH solutions, then successively with absolute ethyl alcohol, 75%
Alcoholic solution and deionized water are cleaned cleans repeatedly, standby after drying.
