Fluoride chicherwa chine chepfu. Chinowanzo kuwanikwa mumvura yekunwa. Mwero wepasi rose wefluoride wakaiswa neWorld Health Organization (WHO) pari zvino i1.5 ppm. Kuwanda kwefluoride kunogona kukonzera fluorosis yemazino nemapfupa, saka fluoride yakawandisa inofanira kubviswa mumvura yekunwa. Pakati pezvinhu zvakasiyana-siyanamakemikari ekurapa mvuraZviripo, polyaluminium chloride (PAC) ndiyo sarudzo yekutanga yekubvisa fluoride. Kugona kwePAC kubvisa fluoride kunobva muhunhu hwayo hwemakemikari uye mashandiro ayo. Ngationgororei mashandiro ayo, zvakanakira uye mashandisirwo ayo.
Maitiro ekuita kwepolyaluminium chloride:
Polyaluminium chlorideichinhu chinoumba mvura chinokonzerwa nekuita kwealuminium hydroxide nehydrochloric acid. Inowanzoshandiswa seflocculant mumabasa ekuchenesa mvura mumakanzuru nemaindasitiri.
Polyaluminium chloride inonyungudutsa uye inosanganiswa nemaion efluoride nemagetsi kuti igadzire mhando dzakasiyana dzema complexes akagadzikana. Izvi zvinobva zvawedzera kuumba uye kukonzera kuti aluminium fluoride isanyungudike.
Maion earuminiyamu nemaion efluoride zvinogonawo kugadzira mhando dzakasiyana dzemacomplexes akasimba (akadai se , kuderedza huwandu hwefluoride yakasununguka mumvura.
Mabhenefiti ePAC semushonga wekubvisa fluoride
Kushanda zvakanaka: PAC inogona kubvisa fluoride zvakanyanya, kazhinji inodarika 90% mumamiriro ezvinhu akanaka. Kana ichienzaniswa nemunyu wealuminium wekare, PAC ine huwandu hwakanyanya hwekuchaja uye huwandu hweflocculation hunokurumidza. Kushanda zvakanaka kwekubvisa fluoride kunowedzerwa ne30% pachiyero chimwe chete.
Mari: Mari yekurapa inoderedzwa neinopfuura 40% kana tichienzanisa nematekinoroji akadai se reverse osmosis, uye hapana michina yakaoma inodiwa.
Uye huwandu hwepH inoshandiswa hwakafara (5.0-9.0). Uye kusviba kwemvura kunogona kuderedzwa panguva imwe chete.
Kugadzirwa kwemarara mashoma: Marara mashoma anoumbwa, izvo zviri nyore kutarisira.
Zvinyorwa pamusoro pePAC semushonga wekubvisa fluoride:
PAC inoshanda zvakanaka kana pH iri pakati peacidic ne neutral (inenge 6.5 kusvika 7.5). Kuchengetedza pH yakakodzera kunoita kuti fluoride ibviswe zvakanyanya.
Kubviswa kwefluoride kunoenderana nehuwandu hwe fluoride hwepakutanga uye chiyero che coagulant.
Kushandiswa kwePAC mukubvisa Fluoride
Kurapa mvura yemuguta: Iva nechokwadi chekuti mvura yekunwa yakachengeteka nekuderedza fluoride kusvika pahuwandu hunogamuchirwa.
Kurapa mvura yakasviba mumaindasitiri: Bvisa fluoride kubva mumvura yakasviba inogadzirwa nemaindasitiri akadai sekugadzira magirazi, kugadzira masemiconductor nemafetereza.
Kugadziriswa kwezvakatipoteredza: Bata pasi pevhu nevhu rakasvibiswa nefluoride yechisikigo kuchengetedza zvakatipoteredza.
Kugadzirisa zvekurima nezvakatipoteredza: Bvisai maFluoride ions mumvura yekudiridza kudzivirira munyu wevhu uye kukuvara kwezvirimwa.
Polyaluminum chloride inzira yakasimbiswa uye inoshanda yekubvisa fluoride mukushandiswa kwekuchenesa mvura. Kukwanisa kwayo kusanganisa nekunyudza maion efluoride kunoita kuti ive sarudzo yekutanga munzvimbo dzemaguta nemaindasitiri. Zvakakosha kusarudza mutengesi wemakemikari akavimbika pakati pevakawanda.Mutengesi wePACs. Unofanira kuona kuti vane hunyanzvi uye kuti chigadzirwa chavo ndechei. Kana uchida rubatsiro pakutenga PAC, ndapota ndiudze. Tinogona kupa masampuli emahara uye mabasa ekusarudza. Ndiri kutarisira kukuona!
