Kugwiritsa Ntchito Polyacrylamide (PAM) mu Kuchiza Madzi Akumwa

Pankhani yokonza madzi, kufunafuna madzi akumwa oyera komanso otetezeka n'kofunika kwambiri. Pakati pa zida zambiri zomwe zikupezeka pa ntchitoyi,polyacrylamide(PAM), yomwe imadziwikanso kuti coagulant, imadziwika kuti ndi mankhwala othandiza komanso ogwira mtima. Kugwiritsa ntchito kwake pochiza kumathandiza kuti zinyalala ndi zinthu zina zichotsedwe, motero kumawonjezera ubwino wa madzi akumwa. Nkhaniyi ikufotokoza momwe polyacrylamide imagwirira ntchito pochiza madzi akumwa, ndikufotokoza udindo wake ngati gawo lofunika kwambiri pakuyeretsa.

1. Kugawanika kwa magazindi Kusakaniza

Chimodzi mwa ntchito zazikulu za polyacrylamide pochiza madzi akumwa ndi pamene madzi amaundana ndi kuyandama. Kuyandama kumaphatikizapo kusokoneza tinthu ta colloidal kudzera mu kuwonjezera mankhwala, zomwe zimathandiza kuti tinthu ta colloidal tiyambe kusonkhana. Polyacrylamide imathandiza pa njirayi mwa kuchepetsa mphamvu yoipa pa tinthu ta pulasitiki tomwe timayimitsidwa, zomwe zimapangitsa kuti tinthu ta pulasitiki tiyambe kusonkhana kukhala tinthu ta pulasitiki tomwe timatha kukhazikika. Pambuyo pake, kuyandama kumaonetsetsa kuti tinthu ta pulasitiki tomwe timakula komanso tokhuthala tipangidwe, zomwe zimatha kuchotsedwa mosavuta kudzera mu njira zosungunulira kapena kusefa.

2. Kuchotsa Zinthu Zodetsa

Polyacrylamide imathandizira kuchotsa zinthu zosiyanasiyana zodetsa zomwe zili m'madzi akumwa. Mwa kuthandizira kupanga ma floc akuluakulu, imapangitsa kuti sedimentation ndi kusefa ziyende bwino, zomwe zimapangitsa kuti zinthu zolimba zomwe zapachikidwa, zinthu zachilengedwe, ndi tizilombo toyambitsa matenda zichotsedwe bwino. Kuphatikiza apo, PAM imathandiza kuchotsa zitsulo zolemera, monga lead ndi arsenic, popanga ma complexes ndi ma ayoni awa, motero amaletsa kuti asafalikirenso m'madzi okonzedwa.

3. Kuchepetsa Kutupa

Kuvunda, komwe kumachitika chifukwa cha tinthu tomwe timapachikidwa m'madzi, sikuti kumakhudza kokha ubwino wa madzi akumwa komanso kumasonyeza ubwino wa madzi. Polyacrylamide imachepetsa bwino kuvunda mwa kulimbikitsa kusonkhana kwa tinthu tating'onoting'ono kukhala tinthu tating'onoting'ono, tomwe timakhazikika mwachangu. Izi zimapangitsa kuti madzi akumwa akhale omveka bwino komanso okongola, akukwaniritsa miyezo yoyendetsera ntchito komanso zomwe ogula amayembekezera.

Pomaliza, polyacrylamide (PAM) imagwira ntchito yofunika kwambiri pochiza madzi akumwa, ndipo imapereka maubwino ambiri pankhani yaKugawanika kwa magazi, kuchotsa zinthu zodetsa, kuchepetsa kukhuthala, kuchotsa algae, ndi kusintha pH. Kusinthasintha kwake komanso kugwira ntchito bwino kwake kumapangitsa kuti ikhale chida chofunikira kwambiri kwa mafakitale ochizira madzi omwe amayesetsa kupereka madzi akumwa oyera, otetezeka, komanso okongola kwa ogula. Pamene kupita patsogolo kwa ukadaulo wochizira madzi kukupitilirabe, polyacrylamide yakonzeka kukhalabe mwala wapangodya pakufuna kasamalidwe ka madzi kokhazikika komanso chitetezo chaumoyo wa anthu.
