Kuchiza kwa Madzi a Wastewater - Flocculants (PAM)

M'madzi otayira m'mafakitale, nthawi zina pamakhala zonyansa zomwe zimapangitsa kuti madzi azikhala ndi mitambo, zomwe zimapangitsa kuti madzi otayirawa akhale ovuta kuyeretsa.Ndikofunikira kugwiritsa ntchito flocculant kuti madziwo azimveka bwino kuti akwaniritse muyezo wotuluka.Kwa flocculant iyi, timalimbikitsaPolyacrylamide (PAM).

Flocculantpochiza madzi otayira m'mafakitale

Polyacrylamide ndi polima wosungunuka m'madzi.Zake maselo unyolo lili polar magulu, amene angathe adsorb particles inaimitsidwa mu yankho ndi agglomerate particles kupanga zazikulu flocs.The lalikulu flocs anapanga akhoza imathandizira mpweya wa inaimitsidwa particles ndi imathandizira zotsatira za yankho kumveka.Poyerekeza ndi mankhwala amadzi onyansa wamba, mankhwala amadzi onyansa ndi ovuta kwambiri.Pochiza madzi onyansa amankhwala, zinthu zosiyanasiyana monga flocculants, coagulants, ndi decolorizers zimafunika.Pakati pawo, flocculant yomwe imagwiritsidwa ntchito kwambiri ndi nonionic polyacrylamide.

Kukula kachitidwe ka Polyacrylamide

1. The polyacrylamide molekyulu unyolo lili magulu polar, amene akhoza kuyamwa particles inaimitsidwa m'madzi ndi mlatho pakati particles kupanga zazikulu flocs.

2. Non-ionic Polyacrylamide akhoza imathandizira mpweya wa inaimitsidwa particles ndi kupanga zazikulu flocs, potero imathandizira kumveketsa njira ndi kulimbikitsa kusefera kwenikweni.

3. Pakati pa zinthu zonse za flocculant, polyacrylamide yosagwiritsa ntchito ionic imakhala ndi zotsatira zabwino pochiza madzi onyansa a acidic, ndipo madzi otayira a mankhwala nthawi zambiri amakhala acidic.Chifukwa chake, polyacrylamide yopanda ionic ili ndi zabwino zake zapaderamankhwala mankhwala amadzi oipa.

4. The coagulant angagwiritsidwe ntchito osakaniza mchere mchere monga polyaluminiyamu, polyiron ndi zina flocculants inorganic, ndipo zotsatira zake ndi bwino.Ndi ndendende chifukwa cha makhalidwe sanali ionic polyacrylamide kuti ali ndi ubwino zoonekeratu pochiza mankhwala madzi oipa.

Timapereka PAM yapamwamba kwambiri pa fakitale yoyamba, kuti muthe kupeza PAM yotsika mtengo komanso chidziwitso chokhutiritsa pambuyo pa malonda.
