Polydadmac, yemwe dzina lake lonse ndi polydimethyediamlyellamom chloride, ndi polymer yosungunuka yamadzi yomwe imagwiritsidwa ntchito pompopompo m'madzi. Chifukwa cha kuchuluka kwake kwapadera kumalipira ndi kusiyanasiyana kwamadzi ambiri, polydadmac ndi njira yabwino kwambiri yomwe imatha kuchotsa bwino, utoto ndi zodetsa m'madzi. Komabe, pamapulogalamu othandiza, nthawi zambiri amagwiritsidwa ntchito ngatimalo ogonaKuphatikiza ndi ma coagulasint ena kuti azitha kuchitira zinyalala zamakampani.
Makhalidwe ndi makina a polydaadmac
Polydadmac mwachangu adsorbs ndi zikuluzikulu zomwe zimasokoneza ma conloidal tinthu tating'onoting'ono ndikuyimitsa zolimba m'madzi chifukwa cha kuchuluka kwake kwa cartic. Mphamvu yake yochita izi imatengera kukopa kwa magetsi, komwe kumayambitsa tinthu tating'onoting'ono tomwe timakhala tinthu tating'onoting'ono tomwe timachita bwino kwambiri.
Njira Yodzilira ya Polydadmac
Kudzikwapula ndi chimodzi mwa njira zomwe zimachitika pakupanga mabatani. Amatanthauza njira yomwe
"Maluwa a alum a alum" opangidwa nthawi ya ma coagulation amapanga mabatani omwe ali ndi tinthu tating'onoting'ono kudzera mu adsorpption, kusachita magetsi, kugwidwa ndi ukonde.
M'makampani azachipatala am'madzi, kusinthasintha kwa magetsi ndi zamagetsi kumalumikizana ngati kugwirizanitsa, pomwe kulumikizana ndi ubwenzi ndi zikwangwani zimangokhalira kutaya. Mankhwala ofananawo amatchedwa coagalants ndi maluwa motsatana.
Nthawi zambiri amakhulupirira kuti polydadmac ali ndi njira zitatu zochitikira: Adsorption, kusachita magetsi ndi kukwatulidwa. Awiri oyamba ndi omwe. Ndiye chifukwa chake polydadmac imalembedwa ngati coagulants. Komabe, anthu ambiri amawonera mgwirizano ndi kukwera chofananira ndi njira yomweyo, motero polydadmac amatchedwanso nyumba yolowera.
M'madzimadzi chithandizo chamadzi kayendedwe, polydadmac amagwiritsidwa ntchito ngati nyumba yowongolera madzi. Makamaka, gulu lokhazikika lamchere la polydadmac limatha kutulutsa zokopa zamagetsi ndi tinthu tanic kuyimitsa kapena tinthu tating'ono m'madzi, ndikulonjeza za tinthu tating'onoting'ono ndikuwakhazikitsa. Maboti awa amasinthidwa panthawi yotsatira kapena njira yoperekera madzi.
Ubwino wa Polydadmac
Poyerekeza ndi maboti a zikhalidwe (alum, pac, etc.), Polydadmac ali ndi zabwino zotsatirazi:
Zokwanira: Ma Polydadmac amatha kuchotsa zosankha mofulumira m'madzi ndikusintha madzi.
Kusavuta kugwiritsa ntchito: Kugwiritsa ntchito kwake ndikosavuta, kumangowonjezera pansi pazoyenera.
Kukhazikika: Ma polydadmac ali ndi bata bwino ndipo samaphwanya mosavuta ngati polyacryamide.
Zotsatira Zamphamvu: Gulu la Mchere wa Chikumbutso umapereka luso lolimbitsa thupi la PDMDAac, momwemonso kuchitira zinthu zosiyanasiyana.
Kutsutsana ndi Mchere Chabwino, acid ndi alkali kukana: PDMDAac ndi yoyenera magwiridwe antchito am'madzi pansi pa mchere wapamwamba, ma acidic kapena alkalinine;
Mtengo wotsika: Polydadmac ali ndi mphamvu yokweza bwino komanso kuchuluka kochepa, komwe kumachepetsa ndalama zamadzi.
Sludge Wotsika: Polydadmac imadzetsa pang'ono kuposa ma rogarants oyambira ndi mabotolonts ndikusunga ndalama zogwirizira pambuyo.
Mlingo wa Polydadmac ndi mosamala
Mukamagwiritsa ntchito polydadMac, njira zogwirira ntchito ziyenera kutsatiridwa mosamalitsa kuti zitsimikizire zotsatira za chithandizo chamankhwala ndipo pewani zotsatira zoyipa. Nthawi zambiri, atawonjezera maluwa monga polyulumium chloride, polydadmac amawonjezeredwa kuti akwaniritse bwino kwambiri. Kuphatikiza apo, kuchuluka kwa mlingo uyenera kusintha moyenera malinga ndi mtundu wamadzi ndi zofuna kulandira chithandizo. Mlingo woyenera ungadziwike ndi mayeso a jar.
Komabe mwazonse,Polydaadmacamatenga gawo lofunikira mu gawo lamadzi. Kumvetsetsa mwakuya za malo ake ndi ntchitozo kungathandize kugwiritsa ntchito bwino malonda kuti musinthe madzi ndikuteteza chilengedwe.
