Zimbudzi za municipal
Mankhwalawa zimbudzi zoweta, Polyacrylamide akhoza kulimbikitsa mofulumira agglutination ndi kuthetsa inaimitsidwa turbidity particles kukwaniritsa zotsatira za kulekana ndi kumveketsa mwa neutralization magetsi ndi adsorption mlatho. Iwo makamaka ntchito flocculation kuthetsa mu gawo kutsogolo ndi sludge dewatering mu gawo kumbuyo kwa zimbudzi mankhwala chomera.
Madzi owonongeka a mafakitale
Powonjezera Polyacrylamide ku madzi inaimitsidwa turbidity particles, akhoza kulimbikitsa mofulumira aggregation ndi kuthetsa inaimitsidwa turbidity particles mwa neutralization magetsi ndi adsorption bridging zotsatira za polima palokha, ndi kukwaniritsa zotsatira za kulekana ndi mafotokozedwe, kotero kuti kusintha kugwira ntchito moyenera komanso kuchepetsa mtengo wogwirira ntchito.
Makampani osindikizira zovala ndi utoto
Monga wothandizila sizing ndi kumaliza wothandizira nsalu pambuyo mankhwala, Polyacrylamide akhoza kupanga zofewa, makwinya-umboni ndi mildew kugonjetsedwa wosanjikiza. Ndi katundu wake wamphamvu wa hygroscopic, imatha kuchepetsa kuthyoka kwa ulusi wopota. Zimalepheretsanso magetsi osasunthika komanso kuchepa kwamoto kwa nsalu. Mukagwiritsidwa ntchito ngati zida zosindikizira ndi zopaka utoto, zimatha kupititsa patsogolo kumamatira komanso kuwala kwa chinthucho; Itha kugwiritsidwanso ntchito ngati si-silicon polima stabilizer poyeretsa. Kuphatikiza apo, itha kugwiritsidwanso ntchito pakuyeretsa bwino kwa kusindikiza kwa nsalu komanso kudaya madzi onyansa.
Makampani opanga mapepala
Polyacrylamide imagwiritsidwa ntchito kwambiri ngati chithandizo chosungira, chothandizira kusefa komanso kufalitsa pakupanga mapepala. Ntchito yake ndikuwongolera mawonekedwe a mapepala, kupititsa patsogolo kuchepa kwa madzi m'thupi kwa slurry, kupititsa patsogolo kuchuluka kwa ulusi wabwino ndi zodzaza, kuchepetsa kugwiritsa ntchito zinthu zopangira komanso kuwononga chilengedwe. Zotsatira za ntchito yake pakupanga mapepala zimadalira kulemera kwake kwa maselo, katundu wa ionic, mphamvu ya ionic ndi ntchito za ma copolymers ena. Nonionic PAM imagwiritsidwa ntchito makamaka kukonza zosefera za zamkati, kuwonjezera mphamvu ya pepala lowuma, kupititsa patsogolo kuchuluka kwa fiber ndi kudzaza; Anionic copolymer imagwiritsidwa ntchito makamaka ngati chowuma komanso chonyowa cholimbikitsa komanso chokhazikika pamapepala. The cationic copolymer imagwiritsidwa ntchito makamaka pochiza madzi otayira a mapepala ndi kuthandizira kusefera, komanso imakhala ndi zotsatira zabwino pakuwongolera kuchuluka kwa kusungirako. Kuphatikiza apo, PAM imagwiritsidwanso ntchito popanga mankhwala amadzi onyansa komanso kuchira kwa fiber.
Makampani a malasha
Madzi ochapira malasha, malo opangira malasha amadzi amatope, malo opangira malasha ochapira madzi otayira, etc., ndi osakaniza amadzi ndi ufa wabwino wa malasha, mawonekedwe ake akuluakulu ndi turbidity, tinthu tating'onoting'ono tating'onoting'ono, pamwamba pa tinthu tating'onoting'ono tolimba. zambiri zoipa mlandu, mphamvu yonyansa pakati pa mlandu womwewo zimapangitsa particles kukhala omwazika m'madzi, anakhudzidwa ndi mphamvu yokoka ndi Brownian kuyenda; Chifukwa cha kugwirizana pakati pa mawonekedwe a olimba particles mu malasha matope madzi, katundu malasha kutsuka madzi zinyalala zovuta kwambiri, amene osati ali ndi katundu kuyimitsidwa, komanso ali katundu wa colloidal. Kuti malasha matope madzi precipitate mwamsanga concentrator, kuonetsetsa oyenerera kutsuka madzi ndi kuthamanga fyuluta malasha kupanga matope kupanga kupanga kothandiza ndi ndalama ntchito, m'pofunika kusankha flocculant yoyenera kulimbikitsa mankhwala malasha matope. madzi. Mitundu yambiri ya polymer flocculation dehydrating agent yopangidwira kuthira madzi a malasha pamalo ochapira malasha ali ndi ntchito yabwino yothira madzi ndipo ndiyosavuta kugwiritsa ntchito.
Makampani opanga zamagetsi ndi electroplating
Njira yochizira wamba ndikusintha pH mtengo wamadzi otayidwa ndi sulfuric acid kukhala 2 ~ 3 mu tanki yoyamba, kenaka yonjezerani kuchepetsa, sinthani pH mtengo ndi NaOH kapena Ca(OH)2 mpaka 7 ~ 8 potsatira. thanki yopangira mpweya wa Cr(OH)3, kenaka yikani coagulant kuchotsa Cr(OH)3 mpweya.
Chomera chopangira zitsulo
Amagwiritsidwa ntchito makamaka kuyeretsa madzi owonongeka kuchokera ku mpweya wa flue wa chosinthira chowomba mpweya, chomwe nthawi zambiri chimatchedwa kuti fumbi kuchotsa zinyalala zamadzi osinthira. The mankhwala a Converter fumbi kuchotsa zinyalala mu zitsulo mphero ayenera kuganizira za mankhwala olimba inaimitsidwa, kutentha bwino ndi kukhazikika madzi khalidwe. The coagulation ndi mpweya mankhwala ya inaimitsidwa nkhani ayenera kuchotsa inaimitsidwa zonyansa lalikulu particles, ndiyeno kulowa mu sedimentation thanki. Onjezani PH chowongolera ndi polyacrylamide mu dzenje lotseguka la thanki ya sedimentation kuti mukwaniritse wamba flocculation ndi sedimentation ya inaimitsidwa nkhani ndi sikelo mu thanki sedimentation, ndiyeno kuwonjezera sikelo inhibitor kwa utsi wa thanki sedimentation. Mwanjira imeneyi, sikuti amangothetsa vuto la kulongosola kwa madzi onyansa, komanso kuthetsa vuto la kukhazikika kwa madzi, kuti akwaniritse bwino chithandizo chamankhwala. PAC ndi anawonjezera mu zimbudzi, ndi polima flocculates inaimitsidwa nkhani m'madzi mu floc yaing'ono. Pamene zimbudzi anawonjezera Polyacrylamide PAM, kudzera zosiyanasiyana chomangira mgwirizano, kotero kuti amakhala amphamvu kumanga mphamvu zazikulu floc, kuti mpweya. Malinga ndi mchitidwewu, kuphatikiza kwa PAC ndi PAM kumakhala ndi zotsatira zabwino.
Mankhwala chomera
Kuchuluka kwa chrominance ndi kuipitsidwa kwa madzi otayidwa makamaka chifukwa cha kusakwanira kwa zinthu zopangira kapena kuchuluka kwa zosungunulira zomwe zimagwiritsidwa ntchito popanga kulowa m'madzi onyansa. Pali zinthu zambiri zomwe zimatha kuwonongeka, kusawola bwino kwachilengedwe, zinthu zambiri zapoizoni komanso zovulaza, komanso zigawo zovuta zamadzi. Zimene zopangira nthawi zambiri zosungunulira zinthu kapena mankhwala ndi mphete dongosolo, amene kumawonjezera vuto la mankhwala a madzi oipa. Kusankha abwino Polyacrylamide mtundu akhoza kukwaniritsa bwino mankhwala kwenikweni.
Fakitale ya ndudu
Kumbuyo kwa sludge kutaya madzi m'thupi, kusankha polyacrylamide flocculant n'kovuta, osiyanasiyana kusintha khalidwe madzi ndi lalikulu, ogwira ntchito luso ayenera kulabadira kusintha kwa khalidwe madzi ndi kuchita zogwirizana sludge dehydrating wothandizila mayeso kusankha wothandizila, ntchito ndi komanso lalikulu, kusankha ambiri a cationic polyacrylamide, maselo kulemera amafuna ndi mkulu, ngati mankhwala anachita liwiro mofulumira, applicability adzakhala kuposa zofunika. za zida.
Bkubwezera
Mankhwalawa nthawi zambiri amatengera ukadaulo wamankhwala a aerobic, monga njira ya sludge activated, high load biological filtration njira ndi njira yolumikizira makutidwe ndi okosijeni. Kuyambira panopa, tingaphunzire kuti flocculant ntchito ndi moŵa ambiri ambiri amagwiritsa amphamvu cationic Polyacrylamide, maselo kulemera chofunika ndi oposa 9 miliyoni, zotsatira zake ndi otchuka kwambiri, mlingo ndi zochepa, mtengo ndi otsika. , ndipo madzi a keke yamatope yopanikizidwa ndi fyuluta nawonso amakhala ochepa.
Chomera chopangira mankhwala
Njira zochizira zimakhala motere: chithandizo chakuthupi ndi mankhwala, chithandizo chamankhwala, chithandizo chamankhwala am'magazi komanso kuphatikiza njira zosiyanasiyana, etc. Njira iliyonse yothandizira ili ndi ubwino ndi zovuta zake. Pakali pano, njira yamadzimadzi yopangira madzi imagwiritsidwa ntchito kwambiri popanga mankhwala opangira madzi otayira ndi mankhwala pambuyo pake, monga aluminium sulphate ndi polyferric sulphate yomwe imagwiritsidwa ntchito m'madzi onyansa achi China, etc. ndi kuwonjezera kwa coagulants zabwino kwambiri.
Fakitale ya chakudya
The chikhalidwe njira ndi thupi kukhazikika ndi zamchere nayonso mphamvu, mu zamchere mankhwala ndondomeko ntchito polima flocculant, kuchita sludge dewatering mankhwala. The polima flocculants ntchito mu gawoli zambiri cationic Polyacrylamide mankhwala ndi mkulu digiri ayoni ndi kulemera maselo.
