Momwe mungaweruzire zotsatira za flocculation za PAM ndi PAC

Monga coagulant yomwe imagwiritsidwa ntchito kwambiri pochiza madzi, PAC imakhala ndi kukhazikika kwabwino kwa mankhwala kutentha kwa chipinda ndipo imakhala ndi pH yochuluka yogwiritsidwa ntchito. Izi zimathandiza PAC kuchitapo kanthu mwachangu ndikupanga maluwa a alum pochiza mitundu yosiyanasiyana ya madzi, motero kuchotsa bwino zinthu zoipitsa m'madzi. Pochiza madzi otayidwa m'mafakitale, PAC imakhudza kwambiri kuchotsa zinthu zovulaza monga phosphorous, ammonia nayitrogeni, COD, BOD ndi ma ayoni achitsulo cholemera. Izi zimachitika makamaka chifukwa cha mphamvu yamphamvu yothira madzi ya PAC, yomwe imatha kuvindikira zinthu zovulazazi kukhala tinthu tating'onoting'ono kudzera mu kulowetsedwa ndi kuzunguliridwa, zomwe zimathandiza kuti zinthuzo zikhazikike komanso kusefedwa pambuyo pake.

PAM: chida chachinsinsi chothandizira kukonza flocculation 

Pogwiritsa ntchito PAC, PAM imagwira ntchito yofunika kwambiri pochiza madzi otayidwa. Monga chopopera madzi cha polima, PAM imatha kusintha mphamvu ya flocculation posintha kulemera kwake kwa mamolekyulu, ionicity ndi digiri ya ioni. PAM ingapangitse floc kukhala yaying'ono ndikuwonjezera liwiro la sedimentation, motero imapangitsa kuti madzi azimveka bwino. Ngati mlingo wa PAM sukwanira kapena wochulukirapo, floc imatha kumasuka, zomwe zimapangitsa kuti madzi azikhala abwino.

Kuweruza momwe PAC ndi PAM zimagwirira ntchito pogwiritsa ntchito floc conditions

Yang'anani kukula kwa ma floc: Ngati ma floc ndi ang'onoang'ono koma akugawidwa mofanana, zikutanthauza kuti chiŵerengero cha mlingo wa PAM ndi PAC sichikugwirizana. Kuti muwongolere zotsatira zake, mlingo wa PAC uyenera kuwonjezeredwa moyenera.

Unikani momwe zinthu zosungunuka zimakhudzira: Ngati zinthu zolimba zomwe zasungunuka ndi zazikulu ndipo mphamvu ya madzi ndi yabwino, koma mphamvu ya madzi ndi yoipa, izi zikusonyeza kuti PAC siwonjezedwa mokwanira kapena chiŵerengero cha PAM sichili choyenera. Pakadali pano, mutha kuganizira zowonjezera mlingo wa PAC pamene mukusunga gawo la PAM losasinthika ndikupitiriza kuwona momwe zinthuzo zimakhudzira.

Yang'anirani mawonekedwe a ma floc: Ngati ma floc ndi okhuthala koma madzi ndi ovunda, mlingo wa PAM ukhoza kuwonjezeredwa moyenera; ngati dothi ndi laling'ono ndipo supernatant ndi yovunda, zimasonyeza kuti mlingo wa PAM ndi wosakwanira, ndipo mlingo wake uyenera kuwonjezeredwa moyenera.

Kufunika kwa mayeso a mtsuko (omwe amatchedwanso kuyesa kwa beaker): Mu mayeso a mtsuko, ngati matope apezeka pakhoma la beaker, zikutanthauza kuti PAM yochuluka yawonjezedwa. Chifukwa chake, mlingo wake uyenera kuchepetsedwa moyenera.

Kuwunika kumveka bwino: Ngati zinthu zolimba zomwe zapachikidwa zili bwino kapena zopyapyala, ngati supernatant ili yomveka bwino, zikutanthauza kuti chiŵerengero cha mlingo wa PAM ndi PAC ndi choyenera.

Mwachidule, kuti tikwaniritse zotsatira zabwino kwambiri za flocculation, mlingo wa PAC ndi PAM uyenera kulamulidwa mosamala ndikusinthidwa. Kudzera mu kuyang'anitsitsa ndi kuyesera, titha kuweruza molondola momwe zinthu ziwirizi zimagwiritsidwira ntchito, motero kukonza njira yoyeretsera zinyalala. Mu ntchito zenizeni, ndikofunikira kuganizira bwino momwe madzi alili, zofunikira pakuyeretsera, magawo a zida ndi zinthu zina kuti tipange dongosolo loyeretsera mankhwala. Kuphatikiza apo, chisamaliro chokwanira chiyenera kuperekedwa pakusunga, kunyamula ndi kukonzekera kwa PAC ndi PAM kuti zitsimikizire kuti mankhwalawa akugwira ntchito bwino komanso otetezeka.
