Momwe mungawonjezere PAM

Polyacrylamide (PAM) ndi polima yolunjika yokhala ndi flocculation, kumatira, kuchepetsa kukoka, ndi zina.Flocculant ya Polymer Organic, imagwiritsidwa ntchito kwambiri pa ntchito yoyeretsa madzi. Pogwiritsa ntchito PAM, njira zoyenera zogwiritsira ntchito ziyenera kutsatiridwa kuti mankhwala asatayike.

Njira Yowonjezerera PAM

KwaPAM Yolimba, iyenera kuwonjezeredwa m'madzi ikasungunuka. Pa mitundu yosiyanasiyana ya madzi, mitundu yosiyanasiyana ya PAM iyenera kusankhidwa, ndipo mayankho amagawidwa m'magulu osiyanasiyana. Mukawonjezera polyacrylamide, samalani mfundo zotsatirazi:

Mayeso a Mtsuko:Dziwani zofunikira ndi mlingo wabwino kwambiri kudzera mu mayeso a mtsuko. Mu mayeso a mtsuko, pang'onopang'ono onjezerani mlingo wa polyacrylamide, onani momwe flocculation imakhudzira, ndikuzindikira mlingo woyenera.

Kukonzekera Njira Yamadzi ya PAM:Popeza anionic PAM (APAM) ndi nonionic PAM (NPAM) ali ndi kulemera kwakukulu kwa mamolekyulu ndi mphamvu yamphamvu, anionic polyacrylamide nthawi zambiri imapangidwa kukhala yankho lamadzi lokhala ndi kuchuluka kwa 0.1% (kutanthauza kuchuluka kolimba) ndi madzi oyera opanda mchere. Sankhani zidebe za aluminiyamu zophimbidwa, zomatidwa, kapena zapulasitiki m'malo mwa zotengera zachitsulo chifukwa ma ayoni achitsulo amathandizira kuwonongeka kwa mankhwala a PAM yonse. Pokonzekera, polyacrylamide iyenera kutsukidwa mofanana m'madzi osakaniza ndikutenthedwa moyenera (<60°C) kuti isungunuke mwachangu. Mukasungunuka, muyenera kuyang'ana kwambiri kuwonjezera chinthucho mofanana komanso pang'onopang'ono mu chosungunula pogwiritsa ntchito njira zosakaniza ndi kutentha kuti mupewe kuuma. Yankho liyenera kukonzedwa pa kutentha koyenera, ndipo kudula kwa makina kwa nthawi yayitali komanso koopsa kuyenera kupewedwa. Ndikofunikira kuti chosakanizira chizungulire pa 60-200 rpm; apo ayi, chidzayambitsa kuwonongeka kwa polima ndikukhudza momwe ntchito ikuyendera. Dziwani kuti yankho lamadzi la PAM liyenera kukonzedwa nthawi yomweyo musanagwiritse ntchito. Kusunga kwa nthawi yayitali kudzapangitsa kuti magwiridwe antchito achepe pang'onopang'ono. Mukayika madzi oundana mu flocculant, kusakaniza mwamphamvu kwa nthawi yayitali kudzawononga floc zomwe zapangidwa.

Zofunikira pa Mlingo:Gwiritsani ntchito chipangizo choyezera kuchuluka kwa PAM. Poyamba kugwiritsa ntchito PAM, ndikofunikira kuwonjezera mwayi woti mankhwala akhudze madzi kuti agwiritsidwe ntchito bwino, kuwonjezera kusakaniza, kapena kuwonjezera kuchuluka kwa madzi.

Zinthu Zofunika Kuzikumbukira Mukawonjezera PAM

Nthawi Yothetsera:Mitundu yosiyanasiyana ya PAM ili ndi nthawi yosiyana yosungunula. Cationic PAM ili ndi nthawi yochepa yosungunula, pomwe anionic ndi nonionic PAM zili ndi nthawi yayitali yosungunula. Kusankha nthawi yoyenera yosungunula kungathandize kukonza mphamvu ya flocculation.

Mlingo ndi Kuchuluka kwa Mankhwala:Mlingo woyenera ndiye chinsinsi chopezera zotsatira zabwino kwambiri za flocculation. Mlingo wochulukirapo ungayambitse kuuma kwambiri kwa colloids ndi tinthu tomwe timapachikidwa, ndikupanga matope akuluakulu m'malo mwa flocs, motero kukhudza ubwino wa madzi otuluka.

Mikhalidwe Yosakaniza:Kuti muwonetsetse kuti PAM ndi madzi otayira akusakanikirana bwino, zida zoyenera zosakaniza ndi njira ziyenera kusankhidwa. Kusakaniza kosagwirizana kungayambitse kusungunuka kosakwanira kwa PAM, zomwe zingakhudze momwe imagwirira ntchito.

Mkhalidwe wa Zachilengedwe m'Madzi:Zinthu zachilengedwe monga pH, kutentha, kuthamanga kwa madzi, ndi zina zotero, zimakhudzanso mphamvu ya PAM yoyenda pansi. Kutengera ndi momwe madzi otayira alili, magawo awa angafunike kusinthidwa kuti apeze zotsatira zabwino.

Kutsata Mlingo:Mu njira yoperekera mankhwala yokhala ndi mankhwala ambiri, ndikofunikira kumvetsetsa njira yoperekera mankhwala ya mankhwala osiyanasiyana. Njira yoperekera mankhwala yolakwika ingakhudze mgwirizano pakati pa PAM ndi ma colloid ndi tinthu tating'onoting'ono tomwe timayimitsidwa, motero zimakhudza mphamvu ya flocculation.

Polyacrylamide(PAM) ndi polima yogwiritsidwa ntchito m'njira zosiyanasiyana, makamaka pochiza madzi. Kuti igwire bwino ntchito yake ndikupewa kuwononga, ndikofunikira kutsatira njira zoyenera zogwirira ntchito. Mwa kuganizira mosamala zinthu monga nthawi yosungunuka, mlingo, kusakaniza, momwe madzi amakhalira, komanso momwe amagwiritsira ntchito mlingo, mutha kugwiritsa ntchito bwino PAM kuti mupeze zotsatira zomwe mukufuna pakusuntha madzi ndikukweza ubwino wa madzi.
