Chifukwa chiyani Polyaluminium Chloride Imatha Kuchotsa Fluoride?

Fluoride ndi mchere wowopsa. Nthawi zambiri amapezeka m'madzi akumwa. Muyezo wapano wapadziko lonse wamadzi akumwa a fluoride wokhazikitsidwa ndi World Health Organisation (WHO) ndi 1.5 ppm. Kuchuluka kwa fluoride kumatha kuyambitsa mano ndi chigoba fluorosis, motero fluoride yochulukirapo iyenera kuchotsedwa m'madzi akumwa. Mwa zosiyanasiyanamankhwala ochizira madzikupezeka, polyaluminium chloride (PAC) ndiye chisankho choyamba chochotsa fluoride. Kuthekera kochotsa kwa fluoride kwa PAC kumachokera kuzinthu zake zapadera zamakina ndi kachitidwe kake. Tiyeni tifufuze makina ake, ubwino ndi ntchito zake.

Njira yogwiritsira ntchito polyaluminium chloride:

Polyaluminium kloridendi inorganic coagulant opangidwa ndi zomwe aluminium hydroxide ndi hydrochloric acid. Nthawi zambiri amagwiritsidwa ntchito ngati flocculant m'matauni ndi mafakitale amadzimadzi.

Polyaluminium chloride electrostatically adsorb ndikuphatikiza ndi fluoride ions kuti apange mitundu yokhazikika yokhazikika. Izi zimapanganso ndikuwonjezera aluminium fluoride yosasungunuka.

Aluminium ions ndi fluoride ions amathanso kupanga mitundu yosiyanasiyana yokhazikika (monga, kuchepetsa kuchuluka kwa fluoride yaulere m'madzi.

Ubwino wa PAC ngati defluoridant

Kuchita bwino kwambiri: PAC imatha kukwaniritsa ziwopsezo zazikulu zochotsa fluoride, nthawi zambiri zimapitilira 90% pamikhalidwe yabwino. Poyerekeza ndi mchere wamtundu wa aluminiyamu, PAC ili ndi kachulukidwe kake komanso kuthamanga kwambiri. Kuchita bwino kwa defluoridation kumawonjezeka ndi 30% pa mlingo womwewo.

Zachuma: Mtengo wamankhwala umachepetsedwa ndi 40% poyerekeza ndi matekinoloje monga reverse osmosis, ndipo palibe zida zovuta zomwe zimafunikira.

Ndipo pH yogwiritsira ntchito ndi yotakata (5.0-9.0). Ndipo turbidity ya madzi akhoza kuchepetsedwa nthawi imodzi.

Kupanga matope otsika: Dothi lochepa limapangidwa, lomwe ndi losavuta kuwongolera.

Ndemanga pa PAC ngati defluoridant:

PAC imagwira bwino ntchito pa acidic pang'ono mpaka kulowerera ndale pH (pafupifupi 6.5 mpaka 7.5). Kusunga pH yoyenera kumatsimikizira kuchotsedwa kwakukulu kwa fluoride.

Kuchotsedwa kwa fluoride kumadalira ndende yoyamba ya fluoride ndi mlingo wa coagulant.

Kugwiritsa ntchito PAC mu Kuchotsa Fluoride

Kuyeretsa madzi a Municipal: Onetsetsani kuti madzi akumwa ali otetezeka pochepetsa fluoride kuti ikhale yovomerezeka.

Kuyeretsa madzi onyansa m'mafakitale: Chotsani fluoride m'madzi oipa opangidwa ndi mafakitale monga kupanga magalasi, kupanga ma semiconductor ndi zomera za feteleza.

Kubwezeretsanso zachilengedwe: Sungani madzi apansi ndi nthaka yomwe yakhudzidwa ndi fluoride wachilengedwe kuti muteteze chilengedwe.

Kukonzanso kwaulimi ndi chilengedwe: Chotsani ayoni a Fluoride m'madzi amthirira kuti mupewe mchere wam'nthaka komanso kuwonongeka kwa mbewu.

Polyaluminium chloride ndi njira yotsimikizirika komanso yothandiza pakuchotsa fluoride pochiza madzi. Kutha kwake kukopa ndi kutsatsa ma ion fluoride kumapangitsa kukhala chisankho choyamba m'malo am'matauni ndi mafakitale. Ndikofunika kwambiri kusankha wothandizira mankhwala odalirika pakati pa ambiriMtengo wa PACs. Muyenera kutsimikizira ziyeneretso zawo ndi mtundu wazinthu. Ngati mukufuna thandizo lililonse pogula PAC, chonde ndidziwitseni. Titha kupereka zitsanzo zaulere ndi ntchito zosankhidwa. Ndikuyembekezera kukuwonani!
