Kodi Polyaluminium chloride imachotsa bwanji zonyansa m'madzi?

Polyaluminium Chloride, nthawi zambiri amafupikitsidwa ngati PAC, ndi mtundu wa inorganic polymer coagulant. Imadziwika ndi kachulukidwe kake komanso kachulukidwe ka polymeric, zomwe zimapangitsa kuti ikhale yothandiza kwambiri pakuphatikizana ndi kuyandama koyipa m'madzi. Mosiyana ndi ma coagulants achikhalidwe monga alum, PAC imagwira ntchito bwino pa pH yotakata ndipo imapanga zinthu zocheperako, zomwe zimapangitsa kuti ikhale njira yosamalira zachilengedwe.

Njira Zochita

Ntchito yayikulu ya PAC pochiza madzi ndikusokoneza ndikuphatikiza tinthu tating'onoting'ono tomwe tayimitsidwa, ma colloids, ndi zinthu za organic. Njirayi, yomwe imadziwika kuti coagulation ndi flocculation, imatha kugawidwa m'magawo angapo:

1. Coagulation: Pamene PAC anawonjezedwa madzi, ayoni kwambiri mlandu polyaluminium neutralize zoipa mlandu padziko inaimitsidwa particles. Neutralization iyi imachepetsa mphamvu zonyansa pakati pa tinthu tating'onoting'ono, kuwalola kuti abwere pafupi.

2. Flocculation: Potsatira coagulation, ndi neutralized particles aggregate kupanga zazikulu flocs. Mtundu wa polymeric wa PAC umathandizira kulumikiza tinthu tating'onoting'ono, ndikupanga ma flocs omwe amatha kuchotsedwa mosavuta.

3. Sedimentation ndi Sefa: Zigulu zazikuluzikulu zomwe zimapangika panthawi ya flocculation zimakhazikika mwachangu chifukwa cha mphamvu yokoka. Dongosolo la sedimentation limeneli limachotsa bwino mbali yaikulu ya zonyansa. Zotsalira zotsalira zimatha kuchotsedwa kudzera mu kusefera, zomwe zimapangitsa kuti madzi azikhala oyera komanso oyera.

Ubwino wa PAC

PACimapereka maubwino angapo kuposa ma coagulants achikhalidwe, zomwe zimapangitsa kutchuka kwake pakuchiritsa madzi:

- Kuchita bwino: PAC ndiyothandiza kwambiri pochotsa zowononga zambiri, kuphatikiza zolimba zoyimitsidwa, organic matter, ngakhale zitsulo zolemera. Kuchita bwino kwake kumachepetsa kufunika kwa mankhwala owonjezera ndi njira.

- Broad pH Range: Mosiyana ndi ma coagulants omwe amafunikira kuwongolera pH molondola, PAC imagwira ntchito bwino pamitundu yonse ya pH, kupangitsa njira yochizira kukhala yosavuta.

- Kuchepetsa Kupanga kwa Sludge: Ubwino umodzi wofunikira wa PAC ndi kuchepa kwa zinyalala zomwe zimapangidwa panthawi yamankhwala. Kuchepetsaku kumachepetsa ndalama zotayira komanso kumachepetsa kuwononga chilengedwe.

- Kugwiritsa Ntchito Ndalama: Ngakhale kuti PAC ikhoza kukhala ndi mtengo wokwera kwambiri poyerekeza ndi mankhwala opangira madzi, ntchito yake yapamwamba komanso kuchepa kwa mlingo nthawi zambiri kumapangitsa kuti pakhale ndalama zambiri zopangira madzi.

PAC Flocculants zikuyimira kupita patsogolo kwakukulu muukadaulo woyeretsa madzi. Kutha kwake kuchotsa bwino zowononga, kuphatikiza zopindulitsa zachilengedwe ndi zachuma, zimayika PAC ngati mwala wapangodya pakufuna madzi aukhondo ndi otetezeka. Pamene madera ambiri ndi mafakitale akulandira njira yatsopanoyi, njira yopita ku tsogolo labwino komanso lokhazikika likuwonekera bwino.
