Kodi Polyaluminium chloride imachotsa bwanji zinthu zodetsa m'madzi?

Polyaluminium mankhwala enaake, yomwe nthawi zambiri imafupikitsidwa kuti PAC, ndi mtundu wa inorganic polymer coagulant. Imadziwika ndi mphamvu yake yayikulu komanso kapangidwe ka polymeric, zomwe zimapangitsa kuti ikhale yogwira ntchito bwino kwambiri pophatikiza ndi kusakaniza zinthu zodetsa m'madzi. Mosiyana ndi ma coagulant achikhalidwe monga alum, PAC imagwira ntchito bwino pa pH yokulirapo ndipo imapanga zinthu zochepa zotsalira, zomwe zimapangitsa kuti ikhale njira ina yabwino yosungira chilengedwe.

Njira Yogwirira Ntchito

Ntchito yaikulu ya PAC pakukonza madzi ndikusokoneza ndikuphatikiza tinthu tating'onoting'ono tomwe timapachikidwa, ma colloid, ndi zinthu zachilengedwe. Njirayi, yomwe imadziwika kuti coagulation ndi flocculation, imatha kugawidwa m'magawo angapo:

1. Kutsekeka kwa PAC: PAC ikawonjezedwa m'madzi, ma ayoni ake a polyaluminium omwe ali ndi mphamvu zambiri amathetsa mphamvu zoyipa pamwamba pa tinthu tomwe timapachikidwa. Kutsekeka kumeneku kumachepetsa mphamvu zonyansa pakati pa tinthu, zomwe zimawathandiza kuti aziyandikirana.

2. Kutsekeka kwa mamolekyu: Pambuyo potsekeka, tinthu tomwe sitinathe kusungunuka timasonkhana pamodzi kuti tipange mamolekyu akuluakulu. Kapangidwe ka PAC kamathandiza kulumikiza tinthuto, ndikupanga mamolekyu akuluakulu omwe amatha kuchotsedwa mosavuta.

3. Kusefa ndi Kusefa: Ma floc akuluakulu omwe amapangidwa panthawi yosefa amakhazikika mwachangu chifukwa cha mphamvu yokoka. Njira yosefayi imachotsa bwino gawo lalikulu la zodetsa. Ma floc otsalawo amatha kuchotsedwa kudzera mu kusefa, zomwe zimapangitsa kuti madzi akhale oyera komanso oyera.

Ubwino wa PAC

PACimapereka ubwino wambiri poyerekeza ndi ma coagulants achikhalidwe, zomwe zimapangitsa kuti kutchuka kwake kukule kwambiri pochiza madzi:

- Kuchita Bwino: PAC ndi yothandiza kwambiri pochotsa zinthu zambiri zodetsa, kuphatikizapo zinthu zolimba zomwe zapachikidwa, zinthu zachilengedwe, komanso zitsulo zina zolemera. Kuchita bwino kwake kumachepetsa kufunika kwa mankhwala ndi njira zina zowonjezera.

- Mtundu Waukulu wa pH: Mosiyana ndi ma coagulants ena omwe amafunikira kuwongolera pH molondola, PAC imagwira ntchito bwino pamtundu wonse wa pH, zomwe zimapangitsa kuti njira yochizira ikhale yosavuta.

- Kuchepa kwa Kupanga kwa Madzi Otayira: Chimodzi mwa zabwino zazikulu za PAC ndi kuchepa kwa kuchuluka kwa madzi otayira omwe amapangidwa panthawi yokonza. Kuchepetsa kumeneku kumachepetsa ndalama zotayira madzi komanso kuchepetsa kuwonongeka kwa chilengedwe.

- Kugwiritsa Ntchito Ndalama Moyenera: Ngakhale kuti PAC ikhoza kukhala ndi mtengo wapamwamba poyerekeza ndi ma coagulants ena achikhalidwe, kugwira ntchito kwake bwino komanso kufunikira kwake kochepa kwa mlingo nthawi zambiri kumapangitsa kuti pakhale ndalama zosungiramo zinthu zotsukira madzi.

Ma PAC Flocculants ikuyimira kupita patsogolo kwakukulu muukadaulo wosamalira madzi. Kutha kwake kuchotsa bwino zinthu zodetsa, kuphatikiza ndi ubwino wa chilengedwe ndi zachuma, kumaika PAC ngati maziko pakufunafuna madzi oyera komanso otetezeka. Pamene madera ndi mafakitale ambiri akulandira yankho latsopanoli, njira yopita ku tsogolo labwino komanso lokhazikika ikumveka bwino.
