Kodi Poly Aluminium Chloride imagwira ntchito bwanji?

M'dziko lothandizira madzi,Poly Aluminium Chloride(PAC) yatuluka ngati coagulant yosunthika komanso yothandiza.Pogwiritsa ntchito kwambiri kuyeretsa madzi akumwa ndi malo oyeretsera madzi oipa, PAC ikupanga mafunde chifukwa cha kuthekera kwake kodabwitsa kumveketsa bwino madzi ndikuchotsa zowononga.M'nkhaniyi, tikufufuza momwe PAC imagwirira ntchito komanso kufunika kwake pankhani yoyeretsa madzi.

Chemistry Kumbuyo kwa PAC:

Poly Aluminiyamu Chloride ndi mankhwala pawiri wopangidwa ndi zotayidwa ndi klorini, ndi chilinganizo AlnCl(3n-m)(OH)m.Chikhalidwe chake chosunthika chimachokera ku mfundo yakuti imatha kukhalapo m'njira zosiyanasiyana malinga ndi chiŵerengero cha aluminium-to-chloride ndi digiri ya polymerization.Kusiyanasiyana kumeneku kumapangitsa PAC kuti igwirizane ndi zovuta zambiri zamadzimadzi.

Coagulation ndi Flocculation:

Ntchito yayikulu ya PAC pochiza madzi ndikuphatikizana ndi kusuntha.PAC ikawonjezeredwa kumadzi osaphika, imakhala ndi hydrolysis.Panthawiyi, imapanga aluminium hydroxide flocs, yomwe imakhala yothandiza kwambiri pakugwira zonyansa zomwe zaimitsidwa m'madzi.Ma aluminiyamu hydroxide flocs amachita ngati maginito ang'onoang'ono, kukopa ndi kumanga pamodzi tinthu ting'onoting'ono monga dothi, mabakiteriya, ndi zinthu zamoyo.

Kuchotsa Zonyansa:

PAC's coagulation-flocculation mechanism imathandizira kuchotsa zonyansa zosiyanasiyana m'madzi, kuphatikiza zolimba zoyimitsidwa, ma colloid, komanso zinthu zina zosungunuka.Pamene flocs ikukula ndi kulemera, imakhazikika pansi pa thanki yopangira mankhwala kupyolera mu sedimentation kapena kutsekeredwa mosavuta ndi zosefera.Izi zimapangitsa kuti pakhale madzi abwino komanso aukhondo.

pH Kusalowerera ndale:

Chimodzi mwazabwino za PAC ndi kusalowerera ndale kwa pH.Mosiyana ndi ma coagulants achikhalidwe monga aluminium sulfate kapena ferric chloride, omwe amatha kusintha kwambiri pH yamadzi, PAC imasunga ma pH kukhala okhazikika.Izi zimachepetsa kufunika kwa mankhwala owonjezera kuti asinthe pH, kufewetsa njira yamankhwala ndikuchepetsa ndalama.

Ubwino Wogwiritsa Ntchito PAC:

Kuchita bwino: PAC imagwira ntchito bwino pamitundu yambiri yamadzi ndi ma turbidities.

Kusinthasintha: Itha kugwiritsidwa ntchito popangira madzi oyambira komanso apamwamba.

Zotsalira Pang'onopang'ono: PAC imapanga zotsalira zochepa, zomwe zimachepetsa mtengo wotaya.

Zotsika mtengo: Kuchita bwino kwake komanso kusalowerera ndale kwa pH kumapangitsa kukhala kusankha kotsika mtengo kwa malo opangira madzi.

Chitetezo: PAC nthawi zambiri imawonedwa ngati yotetezeka kugwiridwa kuposa ma coagulants ena.

Ntchito za PAC:

PAC imapeza ntchito zambiri m'mafakitale osiyanasiyana, kuphatikiza kuthira madzi am'matauni, kuthira madzi onyansa m'mafakitale, komanso m'mafakitale a mapepala ndi nsalu.Kutha kwake kuchotsa zonyansa zambiri kumapangitsa kukhala chida chamtengo wapatali chotsimikizira kuti madzi ali ndi ukhondo komanso otetezeka.

Pomaliza, Poly Aluminiyamu Chloride (PAC) ndi njira yodabwitsa yochizira madzi yomwe imagwira ntchito kudzera mu coagulation ndi flocculation.Kuchita kwake, kusinthasintha, komanso kusalowerera ndale kwa pH kwaiyika ngati njira yabwino yopangira madzi padziko lonse lapansi.Pamene kufunikira kwa madzi aukhondo kukukulirakulirabe, PAC ikadali yofunika kwambiri pakuwonetsetsa kuti anthu padziko lonse lapansi apeza madzi abwino komanso abwino.
