Nyob rau hauv kev nrhiav lub neej zoo niaj hnub no, cov dej ntxhia ua tus sawv cev ntawm cov dej qab zib noj qab haus huv, nws txoj kev nyab xeeb tau dhau los ua ib qho ntawm cov neeg siv khoom txhawj xeeb tshaj plaws. Lub Hong Kong Consumer Council qhov tseeb "Choice" magazine tau tshaj tawm ib tsab ntawv ceeb toom uas lawv tau sim 30 hom dej fwj ntawm lub khw, feem ntau los xyuas qhov kev nyab xeeb ntawm cov dej fwj no. Kev ntsuam xyuas cov tshuaj tua kab mob thiab cov khoom siv los ntawm cov khoom siv tau pom tias ob hom dej fwj nrov hauv Suav teb, "Lub Caij Nplooj Ntoos Hlav" thiab "Lub Caij Nplooj Ntoos Hlav", muaj 3 micrograms ntawm bromate ib kilogram. Qhov no concentration tau tshaj qhov zoo tshaj tus nqi ntawm bromate nyob rau hauv tej yam ntuj tso mineral dej thiab lub caij nplooj ntoos hlav dej rau ozone kev kho mob raws li European Union, uas tau aroused thoob plaws kev txhawj xeeb thiab kev sib tham.

I.Source tsom xam ntawm bromate
Bromate, raws li ib tug inorganic compound, tsis yog ib tug natural tivthaiv ntawm mineral dej. Nws cov tsos yog feem ntau ze ze rau lub ntuj ib puag ncig ntawm lub taub hau dej thiab cov txheej txheem tom ntej. Ua ntej, bromine ion (Br) nyob rau hauv dej taub hau qhov chaw yog lub hauv paus ntawm bromate, uas yog dav pom nyob rau hauv seawater, saline hauv av thiab ib co pob zeb nplua nuj nyob rau hauv bromine minerals. Thaum cov peev txheej no siv los ua cov ntsiab lus tshem tawm dej rau cov dej ntxhia, bromine ions tuaj yeem nkag mus rau hauv cov txheej txheem tsim khoom.
II.ob rab ntaj ntawm ozone tua kab mob
Hauv cov txheej txheem tsim cov dej ntxhia dej, txhawm rau tua cov kab mob thiab ua kom muaj kev nyab xeeb ntawm cov dej zoo, feem ntau cov tuam ntxhab yuav siv ozone (O3) ua cov tshuaj detoxifier. Ozone, nrog nws cov oxidation muaj zog, tuaj yeem decompose organic teeb meem, inactivate kab mob thiab kab mob, thiab tau lees paub tias yog ib txoj kev kho dej zoo thiab ib puag ncig. Bromine ions (Br) nyob rau hauv cov dej yuav tsim bromate nyob rau hauv tej yam kev mob, xws li cov tshuaj tiv thaiv nrog oxidizing muaj zog (xws li ozone). Nws yog qhov txuas no, yog tias tsis tswj kom raug, yuav ua rau cov ntsiab lus bromate ntau dhau.
Thaum lub sijhawm txheej txheem tshuaj tua kab mob ozone, yog tias cov dej hauv dej muaj cov bromide ions siab, ozone yuav hnov mob nrog cov bromide ions los ua bromate. Cov tshuaj tiv thaiv tshuaj no kuj tshwm sim nyob rau hauv tej yam ntuj tso, tab sis nyob rau hauv ib puag ncig kev tswj cov tshuaj tua kab mob, vim lub siab ozone concentration, cov tshuaj tiv thaiv tus nqi yog heev ceev, uas tej zaum yuav ua rau cov ntsiab lus bromate tshaj kev ruaj ntseg qauv.
III. Kev koom tes ntawm Environmental Factors
Ntxiv rau cov txheej txheem tsim khoom, ib puag ncig yam tsis tuaj yeem tsis quav ntsej. Nrog rau qhov hnyav ntawm kev hloov pauv huab cua thoob ntiaj teb thiab ib puag ncig muaj kuab paug, dej hauv av hauv qee thaj chaw yuav raug cuam tshuam ntau dua los ntawm kev cuam tshuam sab nraud. Xws li seawater intrusion, infiltration ntawm kev ua liaj ua teb chiv thiab tshuaj tua kab, thiab lwm yam, uas yuav ua rau kom cov ntsiab lus ntawm bromide ions nyob rau hauv dej, yog li ua rau muaj kev pheej hmoo ntawm bromate tsim nyob rau hauv kev kho mob tom ntej.
Bromate yog ib yam khoom me me uas tsim los tom qab ozone tua kab mob ntawm ntau yam khoom siv xws li dej ntxhia thiab dej roob roob. Nws tau raug txheeb xyuas tias yog Class 2B ua tau carcinogen thoob ntiaj teb. Thaum tib neeg noj bromate ntau dhau lawm, cov tsos mob ntawm xeev siab, mob plab, ntuav thiab raws plab yuav tshwm sim. Hauv cov xwm txheej hnyav dua, qhov no yuav muaj kev cuam tshuam tsis zoo rau lub raum thiab lub paj hlwb!
IV. Lub luag hauj lwm ntawm low-pressure ozone-dawb amalgam teeb hauv kev kho dej.
Tsawg-siab ozone-dawb amalgam teeb, raws li ib hom ntawm ultraviolet (UV) lub teeb qhov chaw, emit spectral yam ntxwv ntawm lub ntsiab yoj ntawm 253.7nm thiab muaj peev xwm ua kom tsis muaj menyuam. Lawv tau siv dav hauv kev kho dej. Nws lub luag haujlwm tseem ceeb ntawm kev ua haujlwm yog siv cov kab hluav taws xob ultraviolet los rhuav tshem cov kab mob. DNA qauv kom ua tiav lub hom phiaj ntawm kev ua kom tsis muaj menyuam thiab tua kab mob.
1, sterilization nyhuv yog qhov tseem ceeb:Lub ultraviolet wavelength emissions los ntawm lub low-pressure ozone-dawb amalgam teeb yog feem ntau concentrated nyob ib ncig ntawm 253.7nm, uas yog lub band nrog lub zog nqus los ntawm microbial DNA xws li cov kab mob thiab cov kab mob. Yog li ntawd, lub teeb tuaj yeem tua cov kab mob, kab mob, kab mob thiab lwm yam kab mob phem hauv dej, ua kom muaj kev nyab xeeb ntawm cov dej zoo.
2 .No chemical residual:Piv nrog rau cov tshuaj tua kab mob tshuaj tua kab mob, tsis tshua muaj siab amalgam teeb sterilizes los ntawm lub cev txhais tau tias tsis muaj tshuaj lom neeg seem, tsis txhob muaj kev pheej hmoo ntawm cov pa phem thib ob. Qhov no yog qhov tseem ceeb tshwj xeeb rau kev kho cov dej haus ncaj qha xws li dej ntxhia
3, tswj dej zoo stability:Nyob rau hauv cov txheej txheem ntawm cov dej ntxhia, lub teeb tsis tshua muaj siab amalgam tsis tsuas yog siv rau kev tua kab mob ntawm cov khoom kawg nkaus xwb, tab sis kuj tuaj yeem siv rau kev kho dej, kev tu kav dej, thiab lwm yam. tag nrho cov txheej txheem ntau lawm.
Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias qhov tsis tshua muaj siab ozone-dawb amalgam teeb emits lub ntsiab nthwv dej ntawm spectrum ntawm 253.7nm, thiab lub wavelength qis dua 200nm yuav luag tsis pom zoo thiab tsis tsim cov ozone siab. Yog li ntawd, tsis muaj ntau tshaj bromate yog tsim thaum lub sij hawm dej sterilization txheej txheem.
Tsis tshua muaj siab UV Ozone Dawb Amalgam Teeb
V. Xaus
Qhov teeb meem ntawm cov ntsiab lus bromate ntau dhau hauv cov dej ntxhia yog qhov nyuaj rau kev kho dej uas yuav tsum muaj kev tshawb fawb tob thiab tshawb nrhiav los ntawm ntau qhov kev xav. Tsis tshua muaj siab ozone dawb mercury teeb, raws li cov cuab yeej tseem ceeb hauv kev kho dej, txhua tus muaj qhov tshwj xeeb zoo thiab siv tau. Hauv cov txheej txheem tsim cov dej ntxhia, cov teeb pom kev zoo tsim nyog thiab cov cuab yeej siv yuav tsum raug xaiv raws li qhov xwm txheej tiag tiag, thiab kev saib xyuas thiab kev tswj xyuas dej yuav tsum tau ua kom muaj zog kom ntseeg tau tias txhua qhov dej ntxhia tuaj yeem ua tau raws li cov qauv kev nyab xeeb thiab purity. Nyob rau tib lub sijhawm, peb yuav tsum tau ua tib zoo saib xyuas cov kev tsim kho tshiab thiab kev siv thev naus laus zis tshiab ntawm kev kho dej, thiab pab txhawb kev txawj ntse thiab lub zog ntxiv los txhim kho kev nyab xeeb thiab zoo ntawm cov dej haus.
