Polydiallyldimethylammonium kloride(PolyDADMAC) ndi yogwiritsidwa ntchito kwambiri ndi cationic polima flocculant ndipo imagwira ntchito yofunikira pakuwongolera madzi. PDADMAC imagwiritsidwa ntchito ngati flocculant ndipo nthawi zina imaphatikizidwa ndi algaecides. Nkhaniyi ifotokoza za ubwino ndi phindu la kugwiritsa ntchito kwa PolyDADMAC kuchokera kuzinthu zomwe zimagwirira ntchito, zochitika zogwiritsira ntchito komanso njira zenizeni zothandizira kukonza madzi.
Makhalidwe oyambira a PolyDADMAC
PolyDADMAC ndi mkulu maselo polima ndi chiwerengero chachikulu cha magulu cationic mu kapangidwe ake maselo, amene bwino adsorb inaimitsidwa particles ndi colloids m'madzi. Makhalidwe ake akuluakulu ndi awa:
1. Mphamvu cationicity: Itha kusokoneza mwachangu tinthu tating'onoting'ono toyimitsidwa m'madzi.
2. Kusungunuka kwamadzi bwino: Ndiosavuta kusungunuka m'madzi ndipo ndiyosavuta kugwiritsa ntchito patsamba.
3. Kukhazikika kwamankhwala: Imatha kukhala ndi magwiridwe antchito apamwamba kwambiri mumitundu yosiyanasiyana ya pH, malo okhala ndi oxidizing komanso malo ometa ubweya wambiri. PDADAC ili ndi kukana kolimba kwa chlorine.
4. Kawopsedwe wotsika: Imakwaniritsa miyezo yoteteza chilengedwe ndipo ndiyoyenera kuthira madzi akumwa.
Njira yochitira PolyDADMAC pochiza madzi
Iwo destabilizes inaimitsidwa particles ndi zoipa mlandu amadzimadzi njira zinthu m'madzi ndi flocculates iwo kudzera magetsi neutralization ndi adsorption bridging. Zimakhala ndi zotsatira zazikulu mu decolorization, ndi kuchotsa zinthu organic.
Zithunzi za PolyDADMACkumapangitsa kuti madzi ayeretsedwe bwino pogwiritsa ntchito njira izi:
1. Malipiro neutralization
Tizidutswa tating'onoting'ono ndi ma colloid m'madzi nthawi zambiri amakhala ndi milandu yoyipa, yomwe imayambitsa kukangana pakati pa tinthu tating'onoting'ono ndikupangitsa kuti zikhale zovuta kukhazikika. Magulu a cationic a PolyDADMAC amatha kutsitsa mwachangu milandu yoyipa, kuchepetsa kunyansidwa kwa electrostatic pakati pa tinthu tating'onoting'ono, ndikulimbikitsa kuphatikizika kwa tinthu.
2. Kusokoneza zotsatira
Mapangidwe a maselo aatali kwambiri a PolyDADMAC amathandizira kupanga "mlatho" pakati pa tinthu tating'onoting'ono, ndikuphatikiza tinthu tating'onoting'ono m'magulu akuluakulu, potero kumapangitsa kuti sedimentation ikhale bwino.
3. Kulimbikitsa kugwidwa kwa maukonde
PolyDADMAC imatha kulimbikitsa "maukonde" opangidwa ndi inorganic coagulant m'madzi kuti agwire bwino zinthu zoyimitsidwa, makamaka m'madzi ochulukirapo kapena oipitsidwa kwambiri.
Zochitika zogwiritsira ntchito PolyDADMAC
1. Kuyeretsa madzi akumwa
PolyDADMAC imagwiritsidwa ntchito ngati flocculant kuchotsa turbidity, tinthu tating'onoting'ono tomwe timayimitsidwa ndi zinthu zachilengedwe m'madzi akumwa. Panthawi imodzimodziyo, chifukwa cha kawopsedwe kakang'ono komanso chitetezo cha chilengedwe, imatha kukwaniritsa miyezo ya chitetezo cha madzi akumwa.
2. Kusamalira madzi oipa
M'matauni ndi mafakitale oyeretsera madzi otayira, PolyDADMAC imagwiritsidwa ntchito nthawi zambiri kupititsa patsogolo ntchito ya sludge dewatering, kuchepetsa chinyezi cha keke yamatope, ndikuchepetsa kwambiri ndalama zogwirira ntchito.
3. Kuyeretsa madzi a mafakitale
Mu mphamvu, petrochemical ndi mafakitale ena, PolyDADMAC amagwiritsidwa ntchito poyeretsa madzi a mafakitale monga madzi ozizira ndi madzi opopera kuti achepetse kuopsa kwa makulitsidwe ndi dzimbiri.
4. Makampani opanga mapepala ndi nsalu
PolyDADMAC imagwiritsidwa ntchito ngati chithandizo chosungira komanso kusefera kuti ipititse patsogolo kuchuluka kwa ulusi ndi zodzaza pamapepala, ndikuchepetsa zomwe zidayimitsidwa m'madzi onyansa.
Njira zowongolera bwino chithandizo chamadzi ndi PolyDADMAC
1. Kupititsa patsogolo kuwongolera kwa mlingo
Mlingo wa PolyDADMAC umagwirizana kwambiri ndi ndende, kukula kwa tinthu tating'onoting'ono komanso kuipitsidwa kwa tinthu tating'onoting'ono m'madzi. Kukhathamiritsa mulingowo kudzera pakuyezetsa mtsuko kumatha kukulitsa kugwedezeka kwake ndikupewa kumwa mopitilira muyeso komwe kumabweretsa kuchulukirachulukira kapena kuipitsidwa kwamadzi kwachiwiri.
2. Synergistic zotsatira ndi inorganic flocculants
Kugwiritsa ntchito PolyDADMAC kuphatikiza ndi flocculants inorganic (monga polyaluminium kolorayidi ndi aluminium sulphate) kumatha kupititsa patsogolo mphamvu ya flocculation. PolyDADMAC itatha kusokoneza mphamvu ya pamwamba pa tinthu tating'onoting'ono, ma flocculants a inorganic amapanganso magulu akuluakulu kupyolera mu kutsekemera ndi kusungunuka.
3. Kupititsa patsogolo njira zopangira madzi
Mothandizidwa ndi machitidwe odzilamulira okha, kuyang'anira nthawi yeniyeni ndi kusintha kwa mlingo wa PolyDADMAC kungathe kukwaniritsidwa kuti athe kuthana ndi kusintha kwa chithandizo chamankhwala chifukwa cha kusinthasintha kwa madzi.
4. Konzani mikhalidwe yolimbikitsa
Pambuyo powonjezera PolyDADMAC, yoyenera yogwira mtima mwamphamvu ndi nthawi imatha kupititsa patsogolo dispersibility ndi flocculation dzuwa. Kukondoweza kwambiri kungayambitse kusweka kwa flocs, pomwe kugwedezeka kosakwanira kumachepetsa kusakanikirana.
5. Sinthani pH mtengo
PolyDADMAC imagwira bwino ntchito mosalowerera ndale mpaka kufooka kwa alkaline. Mukathira madzi acidic kwambiri kapena amchere kwambiri, kusintha pH yamadzi am'madzi kumatha kupititsa patsogolo kusuntha kwake.
Ubwino wa PolyDADMAC
1. Kuchita bwino kwambiri: Kupanga mwachangu kwa ma flocs kuti apititse patsogolo kulekanitsa kwamadzi olimba.
2. Ntchito zosiyanasiyana: Imagwira ntchito pamakhalidwe osiyanasiyana amadzi, makamaka madzi okhala ndi turbidity komanso kuchuluka kwachilengedwe.
3. Chitetezo cha chilengedwe: Kawopsedwe wochepa komanso kuwonongeka kwachilengedwe, mogwirizana ndi zofunikira zoteteza chilengedwe.
Monga yothandiza kwambiriflocculant, PolyDADMAC ili ndi maubwino ofunikira pantchito yopangira madzi chifukwa cha cationicity yake yolimba, kusungunuka kwamadzi bwino komanso kugwiritsa ntchito bwino. Kupyolera mu kukhathamiritsa kwabwino kwa ndondomeko ndi njira zogwirira ntchito, chithandizo chake chamankhwala pakuyeretsa madzi akumwa, zimbudzi ndi madzi akumafakitale zitha kupititsidwa patsogolo.
