Kodi Poly Aluminium Chloride imagwira ntchito bwanji?

Mu dziko la kuyeretsa madzi,Poly Aluminiyamu Chloride(PAC) yakhala ngati mankhwala opha tizilombo toyambitsa matenda omwe amagwiritsidwa ntchito kwambiri komanso ogwira ntchito bwino. Chifukwa chogwiritsidwa ntchito kwambiri poyeretsa madzi akumwa ndi malo oyeretsera madzi otayidwa, PAC ikupanga mafunde chifukwa cha luso lake lodabwitsa loyeretsa madzi ndikuchotsa zinthu zodetsa. M'nkhaniyi, tikuyang'ana kwambiri momwe PAC imagwirira ntchito komanso kufunika kwake pankhani yosamalira madzi.

Chemistry Yomwe Ili M'mbuyo mwa PAC:

Poly Aluminium Chloride ndi mankhwala opangidwa ndi aluminiyamu ndi chlorine, okhala ndi formula ya AlnCl(3n-m)(OH)m. Kapangidwe kake kosiyanasiyana kamachokera ku mfundo yakuti imatha kukhalapo m'njira zosiyanasiyana kutengera chiŵerengero cha aluminiyamu-ndi-chloride ndi kuchuluka kwa polymerization. Kusintha kumeneku kumalola PAC kuti igwirizane ndi zovuta zosiyanasiyana zochizira madzi.

Kutsekeka ndi Kutsekeka kwa Matumbo:

Ntchito yaikulu ya PAC pakukonza madzi ndi kugawanika ndi kuyandama. PAC ikawonjezedwa m'madzi osaphika, imadutsa mu hydrolysis. Panthawiyi, imapanga ma flocs a aluminiyamu hydroxide, omwe amagwira ntchito bwino kwambiri pogwira zinyalala zomwe zimayikidwa m'madzi. Ma flocs a aluminiyamu hydroxide amagwira ntchito ngati maginito ang'onoang'ono, kukoka ndikugwirizanitsa tinthu monga dothi, mabakiteriya, ndi zinthu zachilengedwe.

Kuchotsa Zodetsa:

Njira ya PAC yolumikizira madzi m'madzi imathandiza kuchotsa zinthu zosiyanasiyana zodetsa m'madzi, kuphatikizapo zinthu zolimba zomwe zimapachikidwa, ma colloid, komanso zinthu zina zosungunuka. Pamene ma floc akukula komanso kulemera, amakhazikika pansi pa thanki yoyeretsera madzi kudzera mu sedimentation kapena amatsekeredwa mosavuta ndi zosefera. Izi zimapangitsa kuti madzi oyera komanso oyera apangidwe.

Kusalowererapo kwa pH:

Chimodzi mwa zabwino zodziwika bwino za PAC ndi kusalowerera kwake pa pH. Mosiyana ndi zinthu zosakaniza zachilengedwe monga aluminium sulfate kapena ferric chloride, zomwe zimatha kusintha kwambiri pH ya madzi, PAC imasunga kuchuluka kwa pH kukhala kokhazikika. Izi zimachepetsa kufunikira kwa mankhwala ena kuti asinthe pH, kupangitsa kuti njira yochizira ikhale yosavuta komanso kuchepetsa ndalama.

Ubwino Wogwiritsa Ntchito PAC:

Kuchita Bwino: PAC imagwira ntchito bwino m'madzi osiyanasiyana komanso m'malo ouma.

Kusinthasintha: Itha kugwiritsidwa ntchito poyeretsa madzi oyambira komanso oyambira.

Zotsalira Zochepa: PAC imapanga zinthu zochepa zotsalira za matope, zomwe zimachepetsa ndalama zotayira.

Yotsika Mtengo: Kugwiritsa ntchito bwino kwake komanso kusagwiritsa ntchito pH molakwika kumapangitsa kuti ikhale chisankho chotsika mtengo pa malo oyeretsera madzi.

Chitetezo: PAC nthawi zambiri imaonedwa kuti ndi yotetezeka kuposa ma coagulants ena.

Kugwiritsa ntchito kwa PAC:

PAC imagwiritsa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo kukonza madzi m'mizinda, kukonza madzi otayidwa m'mafakitale, komanso m'mafakitale a mapepala ndi nsalu. Kutha kwake kuchotsa zinthu zambiri zodetsa kumapangitsa kuti ikhale chida chofunikira kwambiri poonetsetsa kuti madzi ali oyera komanso otetezeka.

Pomaliza, Poly Aluminium Chloride (PAC) ndi njira yabwino kwambiri yochizira madzi yomwe imagwira ntchito kudzera mu coagulation ndi flocculation. Kugwira ntchito kwake bwino, kusinthasintha kwake, komanso kusalowerera kwa pH kwayiyika ngati njira yabwino kwambiri yochizira madzi padziko lonse lapansi. Pamene kufunikira kwa madzi oyera kukupitilira kukula, PAC ikadali wosewera wofunikira pakuwonetsetsa kuti anthu padziko lonse lapansi akupeza madzi abwino komanso abwino.
