PolyDADMAC, ine zita rakazara polydimethyldiallylammonium chloride, inonzi cationic mvura-soluble polymer iyo inoshandiswa zvakanyanya mumunda wekuchenesa mvura. Nekuda kweiyo yakasarudzika cationic charge density uye yakakwira kunyungudika kwemvura, PolyDADMAC inoshanda coagulant inogona kunyatso kubvisa turbidity, ruvara uye kumwe kusvibiswa mumvura. Nekudaro, mukushandisa zvinoshanda, inowanzoshandiswa seaflocculantpamwe chete nemamwe macoagulants ekurapa tsvina yeindasitiri.
Hunhu uye maitiro ekuita kwePolyDADMAC
PolyDADMAC inokurumidza adsorb uye inounganidza zvisina kunaka colloidal particles uye yakaturikwa yakaoma mumvura nekuda kwekukwira kwayo cationic charge density. Maitiro ayo echiito anonyanya kuenderana nekukwezva kwemagetsi, izvo zvinoita kuti twudiki twudiki twuungane muzvikamu zvakakura, kuitira kuti zvikwanise kubviswa zvinobudirira panguva yekunaya kunotevera kana kusefa maitiro.
Iyo flocculation mechanism yePolyDADMAC
Flocculation nderimwe rematanho mukuita coagulation. Inoreva nzira iyo iyo
"Maruva madiki alum" akaumbwa panguva yekubatanidza maitiro anoumba flocs ane zvimedu zvakakura kuburikidza neadsorption, magetsi neutralization, bridging uye net-capture.
Muindasitiri yekurapa yemvura, adsorption uye kusarereka kwemagetsi kunoiswa senge coagulation, ukuwo bridging uye net-capture inorondedzerwa se flocculation. Iwo makemikari anoenderana anonzi coagulants uye flocculants zvichiteerana.
Zvinowanzotendwa kuti PolyDADMAC ine nzira nhatu dzekuita: adsorption, magetsi neutralization uye bhiriji. Iwo maviri ekutanga ndiwo makuru. Ndokusaka PolyDADMAC ichinzi coagulants. Nekudaro, vanhu vazhinji vanoona coagulation uye flocculation semaitiro akafanana, saka PolyDADMAC inonzi zvakare flocculant.
Mukugadzirisa kwemvura, PolyDADMAC inonyanya kushandiswa se flocculant yekuvandudza mvura. Kunyanya, iyo cationic quaternary ammonium salt group yePolyDADMAC inogona kugadzira electrostatic kukwezva neanionic yakamiswa zvidimbu kana colloidal particles mumvura, zvichikonzera neutralization, kuumba flocs yezvimedu zvakakura nekuzvigadzirisa. Aya ma flocs anotariswa panguva inotevera sedimentation kana kusefa maitiro kuti achenese kunaka kwemvura.
Zvakanakira zvePolyDADMAC
Kuenzaniswa neyechinyakare flocculants (alum, PAC, nezvimwewo), PolyDADMAC ine zvinotevera zvakakosha mabhenefiti:
Zvinobudirira: PolyDADMAC inogona kukurumidza kubvisa tsvina mumvura uye kuvandudza kunaka kwemvura.
Zviri nyore kushanda: Kushandiswa kwayo kuri nyore, ingoiwedzera pasi pemamiriro akakodzera.
Sustainability: PolyDADMAC ine kugadzikana kwakanaka uye haiputsi nyore sepolyacrylamide.
Yakasimba flocculation mhedzisiro: Iyo cationic quaternary ammonium munyu boka inopa PDMDAAC yakasimba flocculation kugona, nekudaro zvinobudirira kurapa kwakasiyana hunhu hwemvura;
Yakanaka munyu kuramba, asidhi uye alkali kuramba: PDMDAAC yakakodzera kune yakaoma mvura yemhando mamiriro, uye ichine yakagadzikana flocculation performance pasi pepamusoro salinity, acidic kana alkaline mamiriro;
Mutengo wakaderera: PolyDADMAC ine yakakwira flocculation inoshanda uye yakaderera dosage, iyo inogona kuderedza mari yekurapa mvura.
Low sludge: PolyDADMAC inogadzira sludge shoma pane inorganic coagulants uye flocculants uye chengetedza mushure mekugadzirisa mutengo.
PolyDADMAC dosage uye matanho ekuzvidzivirira
Paunenge uchishandisa PolyDADMAC, maitiro ekushanda anofanirwa kuteedzerwa zvakanyanya kuti ave nechokwadi chemhedzisiro yekurapa uye kudzivirira zvinogona kuitika. Kazhinji, mushure mekuwedzera flocculants senge polyaluminium chloride, PolyDADMAC inowedzerwa kuti iwane yakanakisa coagulation mhedzisiro. Mukuwedzera, iyo dosage inofanira kugadziridzwa zvakakodzera maererano nehutano hwemvura uye zvinotarisirwa kurapwa. Chiyero chakakodzera chinogona kutariswa nekuongororwa kwejagi.
Zvese muzvese,PolyDADMACinoita basa rinokosha mumunda wekugadzirisa mvura. Kunzwisisa kwakadzama kwezvivakwa zvayo uye mashandisirwo kuchabatsira zvakanyanya kushandisa chigadzirwa ichi kuvandudza kunaka kwemvura uye kuchengetedza zvakatipoteredza.
