Ozone yog ib qho allotrope ntawm oxygen, nrog rau cov tshuaj formula O3, ib qho hnyav molecular ntawm 48. Cov ntxhiab tsw zoo ib yam li cov tsw tsw ntxhiab, thiab thaum lub concentration siab dhau lawm, nws zoo li tsis hnov tsw ntawm cov roj chlorine. Ozone muaj zog oxidizing zog, xws li muaj peev xwm oxidize nyiaj rau nyiaj peroxide, lead sulfide rau txhuas sulfate, hnov mob nrog poov tshuaj iodide los tsim iodine, thiab turpentine, thee gas, thiab lwm yam tuaj yeem spontaneously ignite hauv ozone.
Thaum muaj dej, ozone yog ib qho tshuaj dawb uas muaj zog uas tuaj yeem oxidize unsaturated organic compounds los tsim ozone ntawm qhov kub thiab txias. Ozone tuaj yeem siv los ua cov tshuaj tua kab mob, tshem tawm plua plav, cua purifier, thiab tshuaj tua kab mob; Ozone tuaj yeem hloov ntau cov catalytic oxidants los yog kub-kub oxidants hauv kev tsim tshuaj, ua kom yooj yim cov txheej txheem ntau lawm. Ozone muaj nyob rau hauv cov huab cua thiab tuaj yeem nqus cov teeb meem luv luv (hauv qab 30 nm) tshav ntuj los ntawm lub hnub, tiv thaiv kom tsis txhob ncav cuag hauv av thiab tiv thaiv kab mob los ntawm UV puas.
A. Ozone tuaj yeem siv los tua cov kab mob thiab kab mob;
B. Txhawb kev nce hauv cov ntshav dawb suav thiab phagocytic kev ua haujlwm hauv lub cev;
C. Cov nyhuv ntawm reactive oxygen hom ntawm cov qe ntshav liab;
D. Tswj kev tiv thaiv kab mob;
E. Txhim khu lub cev muaj peev xwm antioxidant.
Kev thov
1. Kev kho dej khib nyiab
Muaj ob qhov xwm txheej uas ozone oxidation thev naus laus zis siv rau kev kho dej khib nyiab: (1) ozone yog siv los ua kev kho ua ntej lossis tom qab kho, ua ke nrog lwm txoj hauv kev xws li flocculation + ozone, ozone + biofilter (biological activated carbon method, thiab lwm yam), ozone + kev kho membrane; (2) Ozone tus kheej oxidation kev kho mob, xws li ozone, ozone hydrogen peroxide, ozone hydrogen peroxide / UV photooxidation, ozone / UV photooxidation, ozone khoom catalyst (khoom catalyst xws li activated carbon, thiab lwm yam).
2. Coagulation ozone oxidation tshuab
Hauv coagulation ozone oxidation technology, ozone tuaj yeem hloov qhov xwm txheej ntawm cov khib nyiab pov tseg hauv dej, yog li hloov cov nyhuv tshem tawm ntawm chav ua haujlwm coagulation. Txoj kev no tuaj yeem ua rau cov khoom raug tshem tawm hauv dej loj dua, thiab ua rau cov khoom tawg yooj yim los ua coagulable colloidal hais, yog li txo qhov ntau npaum ntawm coagulants thiab txo kev noj cov tshuaj.
3. Ozone biochemical txoj kev
Nyob rau hauv xyoo tas los no, muaj ntau cov ntaub ntawv qhia txog patents siv txoj kev no los kho cov dej khib nyiab. Ozone yog siv los kho cov dej khib nyiab, rhuav tshem cov organic teeb meem hauv dej, txhim kho biodegradability, thiab tom qab ntawd kho nws ntxiv siv cov tshuab ua kom carbon biofilters. Cov thev naus laus zis no siv tag nrho cov khoom muaj zog oxidizing ntawm ozone thiab tus nqi kom zoo dua ntawm biofilters, thiab kev sib xyaw ua ke ntawm ob muaj txiaj ntsig zoo tom qab kho.
4. Ozone ncaj qha aeration kho
Kev siv ob-theem biochemical effluent txoj kev kho nrog ob-theem ozone catalytic oxidation, qhov twg hauv qab ntawm thawj theem ozone catalytic oxidation tank txuas nrog rau theem ob ozone catalytic oxidation tank, thiab theem ob ozone catalytic oxidation tank yog nruab nrog tag nrho qhov hluav taws xob, ua tiav kev txuag hluav taws xob thiab txo nqi, thiab txhim kho COD tshem tawm tus nqi mus rau 20%.
5. Ozone hydrogen peroxide ua ke oxidation
Ozone hydrogen peroxide system yog txheej txheem oxidation siab heev rau kev kho dej khib nyiab. Cov nyhuv synergistic ntawm ozone thiab hydrogen peroxide tuaj yeem tsim cov hydroxyl radicals nrog cov khoom muaj zog oxidizing, uas tuaj yeem tshem tawm cov pa phem hauv dej. Tsis tas li ntawd, cov txheej txheem ozone hydrogen peroxide tseem muaj txiaj ntsig zoo hauv kev tshem tawm cov pa phem ntawm cov dej hauv ntuj.
6. Ozone hydrogen peroxide UV photooxidation
Cov oxidation ua ke nrog catalytic oxidation technology, UV photooxidation ozone txoj kev, yog ib qho txheej txheem oxidation siab heev uas ua ke nrog ozone nrog ultraviolet hluav taws xob, uas tau pib xyoo 1970. Cov txheej txheem ozone hydrogen peroxide UV photocatalytic oxidation txoj kev muaj txiaj ntsig zoo hauv kev kho mob nyuaj rau oxidize tshuaj, thiab tuaj yeem nce tus nqi oxidation los ntawm 10-10000 zaug
