Njira ya Flocculant - Polyacrylamide

In Kuchiza kwa Madzi a Waste Water, padzakhala tinthu ting'onoting'ono tambiri tomwe titayimitsidwa m'madzi onyansa.Kuchotsa tinthu tating'ono ting'onoting'ono ndikupangitsa kuti madziwo azimveka bwino komanso agwiritsidwenso ntchito, ndikofunikira kugwiritsa ntchitoMadzi Owonjezera a Chemical -Flocculants (PAM) kupanga tinthu tating'onoting'ono tomwe tiyimitsidwa Zinyalala kuti zipangike kukhala mamolekyulu akulu ndikukhazikika.

Tinthu tating'onoting'ono ta colloid m'madzi ndi tating'ono, ndipo pamwamba pake ndi hydrated ndikuyimbidwa kuti ikhale yokhazikika.Pambuyo pa flocculant yowonjezeredwa m'madzi, imapangidwa ndi hydrolyzed mu colloid yoyendetsedwa ndi ma ion ozungulira kuti apange micelles yokhala ndi magetsi awiri osanjikiza.

Njira mofulumira yogwira mtima pambuyo dosing anatengera kulimbikitsa mwayi ndi chiwerengero cha kugunda pakati pa colloidal zonyansa particles m'madzi ndi micelles anapanga ndi hydrolysis wa flocculant.Zonyansa particles m'madzi poyamba kutaya bata pansi zochita za flocculant, ndiye coagulate wina ndi mzake mu zikuluzikulu particles, ndiyeno kukhazikika pansi kapena tiwolokere mu malo kulekana.

The mankhwala GT wa liwiro gradient G kwaiye ndi oyambitsa ndi yogwira ntchito nthawi T akhoza mwachindunji kuimira chiwerengero cha kugunda tinthu mu lonse anachita nthawi, ndi coagulation anachita tingati zizilamuliridwa ndi kusintha GT mtengo.Nthawi zambiri, mtengo wa GT umayendetsedwa pakati pa 104 ndi 105. Poganizira mphamvu ya ndende yonyansa ya tinthu pa kugundana, mtengo wa GTC ungagwiritsidwe ntchito ngati chizindikiro chowongolera kuti chiwonetsetse kuti coagulation effect, pamene C imayimira kuchuluka kwa tinthu tonyansa. zimbudzi, ndipo tikulimbikitsidwa kuti mtengo wa GTC ukhale pakati pa 100 kapena apo.

Njira yopangira flocculant kuti ifalikire mofulumira m'madzi ndikusakaniza mofanana ndi madzi onse oipa amatchedwa kusakaniza.Zonyansa particles m'madzi zimagwirizana ndi flocculant, ndipo kudzera mu njira monga psinjika ya magetsi awiri wosanjikiza ndi neutralization magetsi, kukhazikika kumatayika kapena kuchepetsedwa, ndipo njira yopangira ma flocs imatchedwa coagulation.Njira yophatikizika ndi kupanga ma flocs ang'onoang'ono omwe amakula kukhala magulu akulu kudzera m'makina monga adsorption bridging ndi sediment net capture pansi pa chipwirikiti cha zinthu zomanga ndikuyenda kwamadzi kumatchedwa flocculation.Kusakaniza, coagulation ndi flocculation pamodzi amatchedwa coagulation.The kusanganikirana ndondomeko zambiri anamaliza mu kusakaniza thanki, ndi coagulation ndi flocculation ikuchitika mu thanki anachita.
