Kuchiza Madzi Otayidwa ndi Mafakitale - Flocculants (PAM)

Mu madzi otayira m'mafakitale, nthawi zina pamakhala zinthu zodetsa zomwe zimapangitsa madzi kukhala amtambo, zomwe zimapangitsa kuti madzi otayirawa akhale ovuta kuwayeretsa. Ndikofunikira kugwiritsa ntchito flocculant kuti madziwo akhale oyera kuti akwaniritse muyezo wotulutsira madzi. Pa flocculant iyi, tikukulangizanipolyacrylamide (PAM).

Flocculantpochiza madzi otayira m'mafakitale

Polyacrylamide ndi polima wosungunuka m'madzi. Unyolo wake wa mamolekyu uli ndi magulu a polar, omwe amatha kuyamwa tinthu tomwe timapachikidwa mu yankho ndikusonkhanitsa tinthu tating'onoting'ono kuti tipange ma floc akuluakulu. Ma floc akuluakulu omwe amapangidwa amatha kufulumizitsa kunyowa kwa tinthu tomwe timapachikidwa ndikufulumizitsa zotsatira za kumveka bwino kwa yankho. Poyerekeza ndi mankhwala wamba amadzi otayira, mankhwala amadzi otayira ndi ovuta kwambiri. Pochiza madzi otayira ndi mankhwala, zinthu zosiyanasiyana monga ma flocculant, ma coagulant, ndi ma decolorizers amafunika. Pakati pawo, flocculant yomwe imagwiritsidwa ntchito kwambiri ndi nonionic polyacrylamide.

Kuchuluka kwa polyacrylamide m'thupi

1. Unyolo wa mamolekyu a polyacrylamide uli ndi magulu a polar, omwe amatha kuyamwa tinthu tomwe timapachikidwa m'madzi ndikulumikiza tinthu tating'onoting'ono kuti tipange ma flocs akuluakulu.

2. Polyacrylamide yosakhala ionic imatha kufulumizitsa kutsika kwa tinthu tomwe timapachikidwa popanga ma flocs akuluakulu, motero imathandizira kumveka bwino kwa yankho ndikulimbikitsa zotsatira zosefera.

3. Pakati pa zinthu zonse zopangira flocculant, polyacrylamide yosakhala ionic imathandiza kwambiri pochiza madzi otayidwa okhala ndi asidi, ndipo madzi otayidwa a mankhwala nthawi zambiri amakhala ndi asidi. Chifukwa chake, polyacrylamide yosakhala ionic ili ndi ubwino wake wapadera mumankhwala oyeretsera madzi otayira.

4. Coagulant ingagwiritsidwe ntchito pamodzi ndi mchere wosapangidwa ndi zinthu monga polyaluminum, polyiron ndi zina zosapangidwa ndi zinthu ...

Timapereka PAM yapamwamba kwambiri kuti mupeze fakitale yanu, kuti mupeze PAM yotsika mtengo komanso chidziwitso chokwanira mukamaliza kugulitsa.
