I-PolyDADMAC njenge-organic coagulant ne-flocculant: ithuluzi elinamandla lokwelapha amanzi angcolile ezimbonini

Ngokuthuthuka okusheshayo kwezimboni, ukuchithwa kwamanzi angcolile ezimbonini kuye kwanda unyaka nonyaka, okubeka usongo olukhulu emvelweni. Ukuze kuvikelwe imvelo, kufanele sithathe izinyathelo ezisebenzayo zokuhlanza la manzi angcolile. Njengoi-organic coagulant, I-PolyDADMAC kancane kancane iba yisixazululo esithandwayo sokwelapha amanzi angcolile ezimbonini.

Kungani ukwelapha amanzi angcolile ezimbonini?

Izingozi zamanzi angcolile ezimboni azinakuzitshwa. Amanzi angcolile aqukethe inani elikhulu lama-ion ensimbi esindayo, amakhemikhali ayingozi, uwoyela, njll. Lezi zinto ziyingozi kakhulu ezimpilweni zasemanzini nakubantu. Ukukhishwa kwamanzi angcolile isikhathi eside anganakiwe kuzoholela ekungcolisweni kwamanzi, ukulimala kwemvelo, kanye nezifo zabantu.

Ngokukhula okuqhubekayo kokukhiqizwa kwezimboni, amanzi amaningi angcolile akhishelwa ngokuqondile endaweni ezungezile ngaphandle kokwelashwa, alimaza kakhulu ibhalansi yemvelo futhi esongela impilo yabantu. Ngakho-ke, kufanele sithathe izinyathelo zokuhlanza amanzi angcolile ezimbonini ukuze sinciphise umthelela wawo omubi endaweni ezungezile.

Kungani ukhetheI-PolyDADMACukugeza amanzi angcolile ezimbonini?

Ukubhekana nezingozi zamanzi angcolile ezimbonini, izindlela zokwelashwa ezivame ukusetshenziswa zihlanganisa ukudoswa kwe-alum noma i-PAC. Kodwa-ke, lezi zindlela zendabuko zivame ukuba nezinkinga ezifana nomthamo omkhulu we-sludge, ukusebenza okuyinkimbinkimbi, nezindleko eziphezulu. Ngakho-ke, sidinga ukuthola indlela yokwelapha esebenza kahle kakhudlwana, eyongayo, futhi ehambisana nemvelo. Njenge-organic coagulant, i-PolyDADMAC inezakhiwo ezinhle kakhulu ze-flocculation kanye ne-coagulation futhi ingasusa ngokushesha futhi ngempumelelo izinto eziqinile ezimisiwe (ngokuvamile eziqukethe ama-ion ensimbi esindayo namakhemikhali ayingozi) emanzini angcolile. Uma kuqhathaniswa nezindlela zokucubungula zendabuko, i-PolyDADMAC inezinzuzo zokusebenza kalula, ukusebenza kahle kokucubungula okuphezulu, umthamo ophansi we-sludge, nezindleko eziphansi. I-PolyDADMAC iphinde isetshenziswe njenge-ejenti yokukhipha amanzi e-sludge ukunciphisa okuqukethwe kwamanzi odaka olubangelwa ezinye izinqubo zezimboni.

I-PolyDADMAC iwaphatha kanjani amanzi angcolile ezimbonini?

Okokuqala, engeza isisombululo esihlanjululwe se-PolyDADMAC emanzini angcolile ngesilinganiso esithile bese uxuba kahle ngokugqugquzela. Ngaphansi kwesenzo se-coagulant, izinto eziqinile ezimisiwe emanzini angcolile zizohlangana ngokushesha zenze ama-particle flocs amakhulu. Bese, ngezinyathelo zokwelashwa ezilandelayo ezifana nokucwiliswa noma ukuhlungwa, i-floc ihlukaniswa namanzi angcolile ukuze kufezwe injongo yokuhlanza amanzi angcolile.

Lapho usebenzisa i-PolyDADMAC ukwelapha amanzi angcolile ezimbonini, udinga ukunaka lezi zindaba ezilandelayo. Okokuqala, kufanele ukhethe umphakeli onekhwalithi ethembekile ukuze uqinisekise ukuthi i-coagulant ethengiwe isezingeni elifanele. Okwesibili, ngokuya ngemvelo nokugcwala kwamanzi angcolile, umthamo we-coagulant kufanele ukhethwe ngokunengqondo ukuze kugwenywe ukweqisa noma ukwelashwa okwanele okuholela emiphumeleni yokwelashwa engemihle. Ngesikhathi esifanayo, ikhwalithi yamanzi angcolile ahlanzekile kufanele ihlolwe njalo ukuze kuqinisekiswe ukuthi izindinganiso zokulahla ziyafinyelelwa. Ukwengeza, opharetha kufanele bathole ukuqeqeshwa kochwepheshe futhi bajwayelane nezici nokusetshenziswa kwama-coagulants kanye nezinyathelo zokuphepha ukuze kuqinisekiswe ukuphepha nokuzinza kwenqubo yokwelapha.

Kafushane, i-PolyDADMAC, njenge-coagulant ephilayo ephumelelayo neyongayo, inezinzuzo ezibalulekile ekwelapheni amanzi angcolile ezimbonini. Ngokusebenzisa okunengqondo kwe-PolyDADMAC, singakwazi ukunciphisa ngempumelelo ukulimala kwamanzi angcolile ezimbonini emvelweni futhi sivikele ibhalansi yemvelo kanye nempilo yabantu. Ngokuzayo, ngokuthuthukiswa okuqhubekayo kokuqwashisa ngemvelo kanye nentuthuko yezobuchwepheshe, i-PolyDADMAC izodlala indima ebaluleke kakhulu emkhakheni wokuhlanza amanzi angcolile ezimbonini.
