Pofunafuna moyo wapamwamba masiku ano, madzi amchere monga oimira zakumwa zathanzi, chitetezo chake chakhala chimodzi mwa ogula kwambiri. Magazini yaposachedwa kwambiri ya Hong Kong Consumer Council ya "Choice" idatulutsa lipoti momwe adayesa mitundu 30 yamadzi am'mabotolo pamsika, makamaka kuti awone chitetezo chamadzi am'mabotolo awa. Mayesero a zotsalira zophera tizilombo toyambitsa matenda ndi zinthu zomwe zidapangidwa adapeza kuti mitundu iwiri yotchuka yamadzi am'mabotolo ku China, "Spring Spring" ndi "Mountain Spring," inali ndi ma microgram 3 a bromate pa kilogalamu. Kuchulukiraku kwaposa mtengo wokwanira wa bromate m'madzi amchere amchere ndi madzi akasupe opangira mankhwala a ozoni onenedwa ndi European Union, zomwe zadzetsa nkhawa komanso kukambirana.
* Chithunzi chochokera pagulu la anthu.
I.Source kusanthula kwa bromate
Bromate, monga gawo lachilengedwe, sizinthu zachilengedwe zamadzi amchere. Maonekedwe ake nthawi zambiri amagwirizana kwambiri ndi chilengedwe cha malo a mutu wa madzi ndi teknoloji yokonza yotsatila. Choyamba, bromine ion (Br) m'malo amutu wamadzi ndiye kalambulabwalo wa bromate, yomwe imapezeka kwambiri m'madzi a m'nyanja, m'madzi amchere pansi komanso miyala ina yokhala ndi mchere wambiri wa bromine. Magwerowa akagwiritsidwa ntchito ngati malo ochotsera madzi amchere amchere, ma ayoni a bromine amatha kulowa mukupanga.
II. lupanga lakuthwa konsekonse la ozone disinfection
Popanga madzi amchere amchere, kuti aphe tizilombo tating'onoting'ono ndikuwonetsetsa chitetezo chamadzi, opanga ambiri amagwiritsa ntchito ozone (O3) ngati detoxifier. Ozone, yokhala ndi okosijeni amphamvu, imatha kuwola bwino zinthu za organic, kuyambitsa ma virus ndi mabakiteriya, ndipo imadziwika kuti ndi njira yabwino komanso yosamalira zachilengedwe. Bromine ions (Br) m'magwero amadzi amapanga bromate pansi pazifukwa zina, monga momwe zimakhalira ndi oxidizing agents (monga ozoni). Ndi ulalo uwu, ngati sunayendetsedwe bwino, ungayambitse kuchulukira kwa bromate.
Panthawi ya mankhwala ophera tizilombo toyambitsa matenda a ozoni, ngati gwero la madzi lili ndi milingo yambiri ya ayoni a bromide, ozoni amatha kuchitapo kanthu ndi ayoni a bromide kuti apange bromate. Izi zimachitikanso mwachilengedwe m'malo achilengedwe, koma m'malo otetezedwa ndi tizilombo toyambitsa matenda, chifukwa cha kuchuluka kwa ozoni, kuchuluka kwa zomwe zimachitika kumachulukira kwambiri, zomwe zingapangitse kuti zomwe zili mu bromate zipitirire chitetezo.
III. Kupereka kwa Zinthu Zachilengedwe
Kuphatikiza pakupanga, zinthu zachilengedwe sizinganyalanyazidwe. Chifukwa cha kuwonjezereka kwa kusintha kwa nyengo padziko lonse ndi kuipitsidwa kwa chilengedwe, madzi apansi m’madera ena angakhudzidwe kwambiri ndi zisonkhezero zakunja. Monga kulowerera m'madzi a m'nyanja, kulowetsedwa kwa feteleza waulimi ndi mankhwala ophera tizilombo, etc., zomwe zingapangitse zomwe zili ndi ayoni a bromide m'madzi, potero zimawonjezera chiopsezo cha mapangidwe a bromate potsatira chithandizo.
Bromate kwenikweni ndi chinthu chaching'ono chomwe chimapangidwa pambuyo pochotsa ozoni wazinthu zachilengedwe zingapo monga madzi amchere ndi madzi akasupe amapiri. Zadziwika kuti Class 2B zotheka carcinogen padziko lonse lapansi. Anthu akamamwa kwambiri bromate, zizindikiro za nseru, kupweteka m'mimba, kusanza ndi kutsekula m'mimba zimatha kuchitika. Pazovuta kwambiri, izi zitha kukhala ndi zotsatirapo zoyipa pa impso ndi dongosolo lamanjenje!
IV. Udindo wa nyali za amalgam zopanda mphamvu zotsika za ozoni poyeretsa madzi.
Nyali za amalgam zopanda mphamvu zotsika za ozoni, monga mtundu wa gwero la kuwala kwa ultraviolet (UV), zimatulutsa mawonekedwe owoneka bwino a mafunde akulu a 253.7nm komanso kuthekera kotseketsa koyenera. Zakhala zikugwiritsidwa ntchito kwambiri m'munda wamankhwala amadzi. Njira yake yayikulu ndikugwiritsira ntchito kuwala kwa ultraviolet kuwononga tizilombo. Mapangidwe a DNA kuti akwaniritse cholinga choletsa ndi kupha tizilombo.
1, kuletsa kubereka ndikofunikira:Mafunde amtundu wa ultraviolet opangidwa ndi nyali ya amalgam yopanda kupanikizika kwa ozoni imakhazikika kwambiri mozungulira 253.7nm, lomwe ndi gulu lomwe limayamwa mwamphamvu kwambiri ndi ma DNA a tizilombo toyambitsa matenda monga mabakiteriya ndi ma virus. Choncho, nyali imatha kupha mabakiteriya, mavairasi, tizilombo toyambitsa matenda ndi tizilombo toyambitsa matenda m'madzi, kuonetsetsa chitetezo cha madzi.
2 .Palibe mankhwala otsalira:Poyerekeza ndi mankhwala ophera tizilombo toyambitsa matenda, nyali yotsika ya amalgam imatenthetsa ndi njira zakuthupi popanda zotsalira za mankhwala, kupewa ngozi ya kuipitsidwa kwachiwiri. Izi ndizofunikira makamaka pochiza madzi akumwa mwachindunji monga madzi amchere
3, kusunga madzi okhazikika:Popanga madzi amchere, nyali yotsika kwambiri ya amalgam singagwiritsidwe ntchito popangira mankhwala ophera tizilombo tomaliza, komanso itha kugwiritsidwa ntchito popangira madzi, kuyeretsa mapaipi, ndi zina zambiri, kuthandiza kuti madzi azikhala okhazikika. dongosolo lonse lopanga.
Komabe, ziyenera kudziwidwa kuti nyali yotsika ya ozoni yopanda mpweya wa amalgam imatulutsa funde lalikulu la sipekitiramu pa 253.7nm, ndipo kutalika kwa mafunde pansi pa 200nm kumakhala kocheperako ndipo sikutulutsa ozoni wambiri. Chifukwa chake, palibe bromate yochulukirapo yomwe imapangidwa panthawi yotseketsa madzi.
Low Pressure UV Ozone Free Amalgam Nyali
V. Mapeto
Vuto la kuchuluka kwa bromate m'madzi amchere ndizovuta zovuta zamadzimadzi zomwe zimafuna kufufuza mozama ndi kufufuza kuchokera kuzinthu zingapo. Otsika kuthamanga ozoni free mercury nyali, monga zida zofunika m'munda wa mankhwala madzi, aliyense ali ndi ubwino wapadera ndi applicability. Popanga madzi amchere, magwero owunikira oyenerera ndi njira zaukadaulo ziyenera kusankhidwa molingana ndi momwe zilili, ndipo kuyang'anira ndi kuwongolera kwamadzi kuyenera kulimbikitsidwa kuti dontho lililonse lamadzi amchere likwaniritse miyezo yachitetezo ndi chiyero. Panthawi imodzimodziyo, tiyenera kupitiriza kuyang'anitsitsa zomwe zachitika posachedwa komanso kugwiritsa ntchito njira zamakono zogwiritsira ntchito madzi oyeretsera madzi, ndikuwonjezera nzeru ndi mphamvu zowonjezera chitetezo ndi khalidwe la madzi akumwa.
