I-Polydiallyldimethylammonium chloride(I-PolyDADMAC) iyi-cationic polymer flocculant esetshenziswa kabanzi futhi idlala indima ebalulekile emkhakheni wokwelashwa kwamanzi. I-PDADMAC ivamise ukusetshenziswa njenge-flocculant futhi ngezinye izikhathi ihlanganiswa nama-algaecides. Lesi sihloko sizochaza ngezinzuzo nenani elisebenzayo le-PolyDADMAC kusukela ezicini zendlela yokusebenza kwayo, izimo zokusetshenziswa kanye namasu athile okuthuthukisa ukusebenza kahle kokwelashwa kwamanzi.
Izici eziyisisekelo ze-PolyDADMAC
I-PolyDADMAC iyi-polymer yamangqamuzana amaningi anenani elikhulu lamaqembu e-cationic esakhiweni sawo samangqamuzana, angakhangisa ngokuphumelelayo izinhlayiya ezimisiwe nama-colloid emanzini. Izici zayo eziyinhloko zihlanganisa:
1. I-cationicity eqinile: Inganciphisa ngokushesha izinhlayiya ezimiswe okwesikhashana ezifakwe icala elibi emanzini.
2. Ukuncibilika kahle kwamanzi: Kulula ukuncibilika emanzini futhi ilungele ukusetshenziswa endaweni.
3. Ukuzinza kwamakhemikhali: Ingagcina ukusebenza kahle kwe-flocculation ephezulu kumabanga ahlukene we-pH, imvelo ene-oxidizing kanye nemvelo ephezulu yokugunda. I-PDDMAC inokumelana ne-chlorine okuqinile.
4. Ubuthi obuphansi: Ihlangabezana nezindinganiso zokuvikela imvelo futhi ifanele ukwelashwa kwamanzi okuphuza.
Indlela yokusebenza yePolyDADMAC ekwelashweni kwamanzi
Ithuntubeza izinhlayiya ezimisiwe kanye nezinto zesisombululo samanzi ezikhokhiswa kabi emanzini futhi izinyakazise ngokusebenzisa i-neutralization kagesi kanye ne-adsorption bridging. Inemiphumela ebalulekile ekudaleni umbala, kanye nokususwa kwezinto eziphilayo.
I-PolyDADMACkuthuthukisa ukusebenza kahle kokuhlanza amanzi ngokusebenzisa lezi zindlela ezilandelayo:
1. I-Neutralization yezindleko
Izinhlayiya ezimisiwe kanye nama-colloid emanzini ngokuvamile athwala amashaji angemahle, okubangela ukwenyanya phakathi kwezinhlayiya futhi kwenza kube nzima ukuzinza. Amaqembu e-cationic e-PolyDADMAC anganciphisa ngokushesha amacala amabi, anciphise ukucasuka kwe-electrostatic phakathi kwezinhlayiya, futhi akhuthaze ukuhlangana kwezinhlayiyana.
2. Umphumela wokuhlanganisa
Isakhiwo se-molecular chain-chain ye-high-viscosity PolyDADMAC yenza kube "ibhuloho" phakathi kwezinhlayiya eziningi, ihlanganisa izinhlayiya ezincane zibe ama-flocs amakhulu, ngaleyo ndlela ithuthukise ukusebenza kahle kwe-sedimentation.
3. Ukuqinisa umphumela wokuthwebula inetha
I-PolyDADMAC ingaqinisa "isakhiwo senetha" esakhiwe i-coagulant ye-inorganic ekwelapheni kwamanzi ukuze ibambe ngempumelelo into emisiwe elungile, ikakhulukazi emanzini aphezulu noma angcoliswe kakhulu.
Izimo zohlelo lokusebenza ze-PolyDADMAC
1. Ukwelashwa kwamanzi okuphuza
I-PolyDADMAC isetshenziswa njenge-flocculant ukususa i-turbidity, izinhlayiya ezimisiwe kanye nezinto eziphilayo emanzini okuphuza. Ngesikhathi esifanayo, ngenxa yobuthi obuphansi kanye nezici zokuvikela imvelo, ingahlangabezana nezindinganiso zokuphepha kwamanzi okuphuza.
2. Ukuhlanza amanzi angcolile
Ekulapheni kwamanzi angcolile kamasipala nezimboni, i-PolyDADMAC ivame ukusetshenziselwa ukuthuthukisa ukusebenza kokukhipha amanzi ngodaka, ukunciphisa umswakama wekhekhe lodaka, nokunciphisa kakhulu izindleko zokusebenza.
3. Ukuhlanzwa kwamanzi ezimbonini
Ezimbonini zamandla, i-petrochemical nezinye, i-PolyDADMAC isetshenziselwa ukuhlanzwa kwamanzi ezimboni njengamanzi okupholisa kanye namanzi abhayela ukunciphisa izingozi zokukala nokugqwala.
4. Imboni yokwenza amaphepha kanye nezindwangu
I-PolyDADMAC isetshenziswa njengosizo lokugcina nokuhlunga ukuze kuthuthukiswe izinga lokugcinwa kwemicu kanye nezigcwalisi kunqubo yokwenza iphepha, kuyilapho kunciphisa okuqukethwe kwento emisiwe emanzini angcolile.
Amasu okuthuthukisa ukusebenza kahle kokwelashwa kwamanzi nge-PolyDADMAC
1. Ukuthuthukisa ukulawula umthamo
Umthamo we-PolyDADMAC uhlobene eduze nokugxilisa ingqondo, ukusatshalaliswa kosayizi wezinhlayiyana nezici ezingcolisayo zezinhlayiya ezimisiwe emanzini. Ukuthuthukisa umthamo ngokuhlolwa kwembiza kungakhulisa umphumela wawo wokugobhoza ngenkathi ugwema umthamo oweqile oholela ezindlekweni eziphakeme noma ukungcoliswa kwamanzi kwesibili.
2. Umphumela we-Synergistic ngama-flocculants we-inorganic
Ukusetshenziswa kwe-PolyDADMAC kuhlanganiswe nama-flocculant we-inorganic (njenge-polyaluminium chloride ne-aluminium sulfate) kungathuthukisa kakhulu umphumela we-flocculation. Ngemuva kokuthi i-PolyDADMAC inciphise ukushaja okungaphezulu kwezinhlayiya, ama-inorganic flocculants aqhubeka enza ama-flocs amakhulu ngokusebenzisa i-adsorption kanye ne-sedimentation.
3. Thuthukisa izinga lokuzenzekelayo lezinqubo zokuhlanza amanzi
Ngosizo lwezinhlelo zokulawula ezizenzakalelayo, ukuqapha kwesikhathi sangempela nokulungiswa komthamo we-PolyDADMAC kungafinyelelwa ukuze kubhekwane nezinguquko ekusebenzeni kahle kokwelashwa okubangelwa ukushintshashintsha kwekhwalithi yamanzi.
4. Lungiselela izimo ezinyakazayo
Ngemuva kokwengeza i-PolyDADMAC, ukuqina okushukumisayo okufanele nesikhathi kungathuthukisa ukuhlakazeka kwayo nokusebenza kahle kwe-flocculation. Ukunyakazisa ngokweqile kungase kubangele ukuba ama-flocs aphule, kuyilapho ukugoqa okunganele kuzonciphisa umphumela wokuxuba.
5. Lungisa inani le-pH
I-PolyDADMAC isebenza kahle kakhulu ngaphansi kokungathathi hlangothi kwezimo ezibuthakathaka ze-alkaline. Lapho welapha amanzi ane-acidic kakhulu noma ane-alkaline kakhulu, ukulungisa inani le-pH lomzimba wamanzi kungathuthukisa kakhulu umphumela wawo wokugobhoza.
Izinzuzo ze-PolyDADMAC
1. Ukusebenza kahle okuphezulu: Ukwakheka okusheshayo kwama-flocs ukuthuthukisa ukusebenza kahle kokuhlukaniswa koketshezi oluqinile.
2. Uhla olubanzi lwezinhlelo zokusebenza: Isebenza ezimfanelweni ezihlukahlukene zamanzi, ikakhulukazi amanzi ane-turbidity ephezulu kanye nokuqukethwe okuphezulu kwe-organic.
3. Ukuvikelwa kwemvelo: Ubuthi obuphansi kanye nokubola kwemvelo, ngokuhambisana nezidingo zokuvikelwa kwemvelo.
Njengomsebenzi osebenza kahle kakhului-flocculant, I-PolyDADMAC inezinzuzo ezibalulekile zohlelo lokusebenza emkhakheni wokwelashwa kwamanzi ngenxa yokuqina kwayo okuqinile, ukuncibilika kwamanzi okuhle nokusetshenziswa okubanzi. Ngokusebenzisa inqubo efanelekile kanye namasu okusebenza, ukusebenza kahle kokwelashwa kwawo ekuhlanzeni amanzi okuphuza, indle kanye namanzi ezimboni kungathuthukiswa.
