Polydiallimethylammonium chloride(I-PolydadMac) iyi-cationer polymer flocculant esetshenziswa kabanzi futhi idlala indima ebalulekile emkhakheni wokwelashwa kwamanzi. I-PDADMAC ivame ukusetshenziswa njenge-flocculant futhi kwesinye isikhathi ihlanganiswe ngama-algaecides. Lo mbhalo uzocacisa ngezinzuzo kanye nokwakheka kohlelo lokusebenza lwePolydadMac kusuka ezicini zokwenziwa kwalo, izimo zohlelo lokusebenza namasu athile okuthuthukisa ukusebenza kahle kwamanzi.
Izici eziyisisekelo zePolydadMac
I-PolydadMac iyi-polymer ephezulu yama-molecular enenombolo enkulu yamaqembu ama-cationic esakhiweni sayo samangqamuzana, esingenza ngempumelelo ama-adsorb amise izinhlayiya nama-colloids emanzini. Izici zalo eziphambili zifaka:
1. I-catiocity eqinile: Kungashesha ukungakhohlisi izinhlayiya ezimisiwe ezimisiwe emanzini.
2. I-solubility yamanzi enhle: Kulula ukuncibilikisa emanzini futhi kulungele uhlelo lokusebenza lwesayithi.
3. Ukuqina kwamakhemikhali: Kungagcina ukusebenza kahle kwe-floccation kokusebenza okusebenzayo kumabanga ahlukile we-PH, i-oxidizizing emvelweni kanye nemvelo ephezulu ye-mechan shear. I-Pdadmac inokumelana okuqinile kwe-chlorine.
4. Ubuthi obuphansi: Ihlangabezana namazinga okuvikela ezemvelo futhi ilungele ukuphuza ukwelashwa kwamanzi.
Indlela yokwenza i-polydadmac ekwelashweni kwamanzi
Ibeka izinhlayiya ezimisiwe kanye nezinto ezinamanzi abhekene necala elinamanzi amaningi emanzini futhi zizigasele ngokungathathi hlangothi kukagesi kanye nokubopha kwe-adsortion. Inemiphumela ebalulekile ekuhlolweni, nasekususweni kwezinto eziphilayo.
I-PolydadMackuthuthukisa ukusebenza kahle kwamanzi ngezinqubo ezilandelayo:
1. Shaja ukungathathi hlangothi
Izinhlayiya ezimisiwe nama-colloids emanzini zivame ukuphatha izindleko ezingezinhle, ezibangela ukuphazamiseka okuhlukile phakathi kwezinhlayiya futhi kwenza kube nzima ukuzinza. Amaqembu we-cationic of polydadmac angavuma ngokushesha izindleko ezingezinhle, anciphise ukuxabana ngogesi phakathi kwezinhlayiya, nokukhuthaza inhlayiya yezinhlayiyana.
2. Umphumela weBrodging
Ukwakheka kwamangqamuzana ama-polydadmac aphezulu we-polydadmac ephezulu kukusiza ukuthi kwakhiwe "ibhuloho" phakathi kwezinhlayiya eziningi, ukuhlanganisa izinhlayiya ezincane kube ama-flocs amakhulu, ngaleyo ndlela kuthuthukise ukusebenza kahle kwe-sedimentation.
3. Ukuqinisa umphumela wokubamba inetha
I-PolydadMac ingaqinisa "isakhiwo set" esakhelwe ubumbano be-inorganic ekuthini ukwelashwa kwamanzi ukuze bathwebule kahle udaba oluhle lokumiswa, ikakhulukazi kuma-turbidity aphezulu noma emanzini angcoliswe kakhulu.
Izimo zesicelo sePolydadMac
1. Ukuphuza ukwelashwa kwamanzi
I-PolydadMac isetshenziswa njenge-flocculant ukususa i-turbidity, izinhlayiya ezimisiwe nezinto eziphilayo ezivela emanzini okuphuza. Ngasikhathi sinye, ngenxa yezici zayo eziphansi zobuthi kanye nezimpawu zokuvikela ezemvelo, kungahlangana namazinga okuphepha okuphuza amanzi.
2. Ukwelashwa kwamanzi
Ekwelashweni kwamanzi omasipala nasezimbonini, i-polydadmac ivame ukusetshenziselwa ukuthuthukisa ukusebenza kwe-sludge anikinayo, yehlisa umswakama wekhekhe kadaka, futhi unciphise kakhulu izindleko zokusebenza.
3. Ukuhlanzwa kwamanzi kwezimboni
Emandleni, ama-petrochemical kanye nezinye izimboni, i-polydadmac isetshenziselwa ukuhlanzwa kwamanzi ezimbonini njengamanzi apholile namanzi e-boiler ukunciphisa ubungozi bokugqwala nokugqwayiza.
4. Imboni ye-papermang kanye nendwangu yendwangu
I-PolydadMac isetshenziswa njenge-retention and fieltration Aid yokwenza ngcono izinga lokugcinwa kwemicu kanye nama-filler kwinqubo yokuphambana, ngenkathi kunciphisa okuqukethwe yindaba emisiwe emanzini angcolile.
Amasu wokuthuthukisa ukusebenza kahle kwamanzi ngePolydadMac
1. Ukulungiselela ukulawulwa kwemithamo
Umthamo wePolydadMac uhlobene kakhulu nokuhlushwa, ukusatshalaliswa kosayizi wezinhlayiyana kanye nezimpawu zokungcola zezinhlayiya ezimisiwe emanzini. Ukwenza kahle umthamo ngokuhlolwa kwe-jar kungakhulisa umphumela wayo we-floccution ngenkathi ugwema umthamo owedlulele oholela ezindlekweni ezengeziwe noma ukungcoliswa kwamanzi kwesibili.
2. Umphumela we-Synergistic nge-Inorganic Flocculants
Ukusetshenziswa kwePolydadMac kuhlanganiswe ne-Inorganic Flocculants (njengePolyaluminium Chloride ne-Aluminium Sulfate) kungathuthukisa kakhulu umphumela we-floccation. Ngemuva kokuthi iPolydadMac inqoba imali engaphezulu kwezinhlayiya, ama-inorganic flocculatants aqala ama-flocs amakhulu ngokusebenzisa i-adsorption kanye nokudideka.
3. Thuthukisa izinga lokuzenzakalela lezinqubo zokwelashwa kwamanzi
Ngosizo lwezinhlelo zokulawula ezenzakalelayo, ukuqapha kabusha isikhathi kanye nokulungiswa komthamo wePolydadMac kungatholakala ukuze kubhekane nezinguquko ekusebenzeni kahle kokwelashwa okubangelwa ukuguquguquka kwekhwalithi yamanzi.
4. Lungiselela izimo ezishukumisayo
Ngemuva kokungeza i-polydadMac, ukuqina okuvusa amadlingozi nesikhathi esifanelekile kungathuthukisa ukungafani kwayo nokusebenza kahle kwe-floccution. Ukuvuselela ngokweqile kungadala ukuthi ama-flocs aphule, ngenkathi ukushukumisa okunganele kuzonciphisa umphumela wokuxuba.
I-5. Lungisa inani le-PH
IPolydadMac isebenza kahle ngaphansi kokungathathi hlangothi ezimweni ezibuthakathaka ze-alkaline. Lapho uphathe kakhulu amanzi a-acidic noma anama-alkali e-alkali
Izinzuzo zePolydadMac
1. Ukusebenza kahle okuphezulu: Ukwakheka okusheshayo kwama-flocs ukuthuthukisa ukusebenza kahle kokwehlukanisa okuqinile.
2. Uhla olubanzi lwezicelo: Kusebenza ezimfanelweni zamanzi ezahlukahlukene, ikakhulukazi amanzi anobunzima obuphezulu nokuqukethwe okuphezulu kwe-organic.
3. Ukuvikelwa Kwezemvelo: Ubuthi obuphansi kanye ne-biodegradabilibility, ngokuhambisana nezidingo zokuvikelwa kwemvelo.
Njengokusebenza kahle kakhului-flecculontant, I-polydadmac inezinzuzo zesicelo esibalulekile emkhakheni wokwelashwa kwamanzi ngenxa ye-caticicity yayo eqinile, i-soubelity yamanzi enhle nokusebenza okubanzi. Ngokusebenzisa inqubo efanelekile kanye namasu okusebenza, ukusebenza kwawo kwelashwa ekuhlanzeni kwamanzi okuphuza, indle kanye namanzi ezimboni kungathuthukiswa.
