Chida chosamalira chilengedwe komanso chothandiza pochiza madzi

M'dziko lamakono, kuteteza ndi kugwiritsa ntchito madzi kwakhala chinthu chofunika kwambiri padziko lonse lapansi. Chifukwa cha kufulumira kwa mafakitale, kuipitsa madzi kukukulirakulira. Momwe mungasamalire ndi kuyeretsa zinyalala bwino kwakhala vuto lofunika kuthetsedwa mwachangu. Pachifukwa ichi, PAM polymer flocculant idayamba kugwiritsidwa ntchito, ndipo yapambana chiyanjo cha ogwiritsa ntchito ambiri chifukwa cha mphamvu zake zamankhwala komanso mphamvu zake zochizira madzi bwino.

PAM, dzina lonse la polyacrylamide, ndi polymer flocculant. Ndi mtundu wa polymer wambiri wopangidwa ndi free radical polymerization ya acrylamide. Chogulitsachi chili ndi kulemera kwakukulu kwa mamolekyulu ndipo chimatha kupanga tinthu tating'onoting'ono ta flocculant, tomwe timafalikira bwino komanso tokhazikika m'madzi, ndipo timatha kuyamwa ndikuchotsa bwino zinthu zopachikidwa ndi zoipitsa zomwe zimasungunuka m'madzi.

Njira yogwiritsira ntchito PAM polymer flocculant ndi yosavuta kwambiri. Choyamba, yankho la PAM limawonjezeredwa ku madzi oti akonzedwe, kenako posakaniza kapena kusakaniza ndi makina, PAM ndi madzi zimasakanizidwa bwino kuti apange flocculant yayikulu. Flocculant iyi imakhazikika m'madzi, motero kukwaniritsa cholinga chochotsa zoipitsa. Chifukwa cha kukhazikika kwa mankhwala, madzi okonzedwa amatha kutulutsidwa mwachindunji m'chilengedwe popanda kusinthidwa.

Ubwino wa mankhwalawa si kokha kuti ndi othandiza pochiza madzi. Choyamba, ndi wotsika mtengo kugwiritsa ntchito. Poyerekeza ndi njira zachikhalidwe zochizira madzi, monga mvula, kusefa, ndi zina zotero, kugwiritsa ntchito mankhwalawa ndikosavuta komanso kotsika mtengo. Kachiwiri, mankhwalawa sakhudza kwambiri ubwino wa madzi. Sasintha mphamvu za mankhwala a madzi, kotero sayambitsa kuipitsa chilengedwe. Pomaliza, zotsatira za mankhwalawo ndi zabwino, zimatha kuchotsa bwino zinthu zopachikidwa ndi zoipitsa zomwe zasungunuka m'madzi, kukonza kuwonekera bwino kwa madzi ndi zizindikiro zomvera.

Kawirikawiri, PAM polymer flocculant ndi chida chothandiza komanso chosamalira chilengedwe pochiza madzi. Kutuluka kwake sikuti kumangopereka njira yatsopano yothetsera vuto la kuipitsidwa kwa madzi, komanso kumapereka chithandizo champhamvu chaukadaulo cholimbikitsa kasamalidwe ka madzi kobiriwira komanso kokhazikika. M'tsogolomu, ndi kupita patsogolo kwa sayansi ndi ukadaulo komanso kukulitsa chidziwitso cha chilengedwe, tili ndi chifukwa chokhulupirira kuti mankhwalawa adzachita gawo lalikulu pantchito yochiza madzi.
