Ukwelashwa kwamanzi angcolile ezimayini kungenye yezici eziyinselele kakhulu ekuphathweni kwamanzi ezimbonini.I-Polyacrylamide(PAM), njenge-flocculant esebenza kahle kakhulu, idlala indima ebalulekile ekuvubukuleni ukwelashwa kwamanzi amdaka. Kodwa-ke, akuyona yonke imikhiqizo ye-PAM efanelekela ukuvubukula ukwelashwa kwamanzi amdaka. Ukukhetha uhlobo olufanele, isisindo sama-molecule, ubuningi beshaja, kanye nendlela yokusebenzisa kuthinta ngqo ukusebenza kahle kokwelashwa, ukusebenza kahle kwezindleko, kanye nokuhambisana nezindinganiso zokukhipha amanzi amdaka.
Lesi sihloko sizochaza kabanzi indlela yokukhetha umkhiqizo we-PAM ofanele wezidingo zokwelashwa kwamanzi amdaka okumbiwa phansi, sihlose ukusiza onjiniyela, amaqembu okuthenga, kanye nabaqhubi bezitshalo ekwenzeni izinqumo ezinolwazi.
Ukuqonda Izici Zamanzi Angcolile Ezimayini
Amanzi amdaka okumba avame ukuqukatha amazinga aphezulu ezinto eziqinile ezilengayo, izinsimbi ezisindayo, izinhlayiya ezincane, kanye nezinsalela zamakhemikhali. Ukuqonda izakhiwo zamanzi amdaka okumba kubalulekile ngaphambi kokukhetha i-PAM. Imisebenzi ehlukene yokumba ikhiqiza izinhlobo ezahlukene zamanzi amdaka:
Imithombo Evamile Yokumbiwa Kwamanzi Angcolile
- ▶ Ukumba amalahle nokuwasha
- ▶ Ukumbiwa kwensimbi (igolide, ithusi, insimbi, i-zinc)
- ▶ Ukumbiwa komhlaba okungajwayelekile
- ▶ Ukumba kanye nokucubungula okuhlanganisiwe
- ▶ Ukukhishwa kokuthunga
Izinto Ezingcolisayo Ezivamile Emanzini Angcolile Ezimayini
- ▶ Izinto eziqinile ezilenga kahle (ubumba, i-silica, i-silt)
- ▶ Ama-ion ensimbi aqinile (insimbi, ithusi, i-lead, i-zinc, i-manganese)
- ▶ Ukungcola okuphezulu
- ▶ Izimo ze-pH ezi-acidic noma ze-alkaline
- ▶ Ama-colloid e-organic kanye ne-inorganic
Izinselele Zokunakekelwa Kwamanzi Angcolile Ezimayini
- ▶ Usayizi wezinhlayiya ezincane kakhulu (kunzima ukuzinza ngokwemvelo)
- ▶ Ukuqina okuqinile kokushaja kobuso be-colloids
- ▶ Umthamo omkhulu wodaka
- ▶ Ukwehluka kwekhwalithi yamanzi kuzo zonke izigaba zokumba
Ngenxa yalezi zici, ukusebenza kahle kwe-flocculation kuba yinto ebalulekile empumelelweni yokwelashwa, kanti i-polyacrylamide (PAM) isetshenziswa kabanzi njengekhemikhali eyinhloko.
Indima yePolyacrylamide Ekuhlinzekweni Kwamanzi Angcolile Ezimayini
I-Polyacrylamide (PAM) iyi-polymer encibilika emanzini esetshenziswa njenge-flocculant. Ihlanganisa izinhlayiya ezilengayo zibe ama-floc amakhulu, ngaleyo ndlela isheshise ukuthungwa noma ukuhlunga.
- ✓ Ukuhlukaniswa okuqinile noketshezi okuthuthukisiwe
- ✓ Ijubane lokuzinza elikhuphukile
- ✓ Ukuncipha kokungcola
- ✓ Ukususwa kwamanzi kodaka olusizayo
- ✓ Kwehlisa isidingo se-oxygen yamakhemikhali (i-COD) kwezinye izimo
Izinhlobo zePolyacrylamide
I-PAM ivame ukuhlukaniswa ngezigaba ezintathu:
Kuye ngezici ezithile zamanzi angcolile, ukusebenza kahle kokwelashwa kohlobo ngalunye kuyahlukahluka.
Izici Ezibalulekile Zokukhetha i-PAM Emanzini Angcolile Ezimayini
Ukukhetha i-PAM akuyona isinqumo esithathwa kanye kuphela. Izici ezilandelayo kumele zihlolwe ngokucophelela.
Uhlobo lwe-PAM (Ukukhethwa Kwenkokhelo)
I-Anionic Polyacrylamide (PAM) isetshenziswa kabanzi ekuvubukuleni amanzi angcolile ngoba izinhlayiya eziningi zamaminerali zineshaja enhle—noma ishaja engathathi hlangothi—ngaphansi kwezimo ze-asidi, ngaleyo ndlela kuvumela ukumuncwa okuphumelelayo.
Okufanelekile Kakhulu Ku:
- Amanzi amdaka okugeza amalahle
- Ukulungiswa kwensimbi
- Ukwelashwa kwemisila

- Ukususwa kwamanzi kodaka emisebenzini yezimayini
- Amanzi angcolile aqukethe izinhlayiya eziphilayo ezishajelwe kabi
Izinzuzo:
- Ukunciphisa ukushaja okunamandla
- Isebenza kahle ekwelapheni udaka
I-polyacrylamide engeyona i-ionic isetshenziswa ezimweni ezikhethekile lapho ukusebenzisana kwe-electrostatic kuncane khona.
Okufanelekile Kakhulu Ku:
- Amanzi amdaka aphansi kokungcola
- Izinhlelo ezinosawoti omningi
- Izindawo ze-pH ezingathathi hlangothi
Ukukhethwa Kwesisindo Se-Molecular
Isisindo sama-molecule sinquma ubude beketanga le-polyacrylamide (PAM) futhi sithonya ngqo usayizi wama-flocs.
Isisindo Esiphansi Sama-Molecular
- Incibilika ngokushesha okukhulu
- Ikhono lokwakha i-floc elibuthakathaka
- Akuvamile ukusetshenziswa ekumbeni amanzi angcolile
- Ukusebenza okulinganiselayo
- Ifanele amanzi anomswakama ophakathi nendawo
Isisindo Esiphezulu Sama-Molecular

- Yakha ama-floc amakhulu, ahlala ngokushesha
- Ifanelekela ukwelashwa kwamanzi amdaka emigodini
Isincomo:
Emanzini angcolile okumbiwa phansi—ngenxa yokuba khona kwezinhlayiya ezincane nezizinzile—i-polyacrylamide (PAM) enesisindo esikhulu sama-molecule ngokuvamile iyindlela ekhethwayo.
Ubuningi beshaja
Ubuningi beshaja bubhekisela enanini leshaja ye-ionic ekhona kuchungechunge lwe-polymer.
Ubuningi be-Charge Low
- Kufanelekela amanzi angcoliswe kancane
- Amandla okugoqana abuthakathaka
Ubuningi Beshaja Ephakathi
- Ukusebenza okulinganiselayo
- Ifanele izimo zamanzi angcolile axubile
Ubuningi Bokushaja Okuphezulu
- Ukusondelana okunamandla kokumuncwa kwezinhlayiya
- Ilungele kakhulu ukwelapha amanzi amdaka okumba izimayini agcwele kakhulu
Izincomo Zokwelashwa Kwamanzi Angcolile Ezimayini:
Ukushaja Okuphezulu → I-Anionic Polyacrylamide Enobuningi Obushaja Okuphezulu
Izinhlelo Ezixubile → I-PAM Yobuningi Beshaja Ephakathi
Izimo ze-pH zamanzi
I-pH idlala indima ebalulekile ekusebenzeni kahle kwe-flocculation.
- Amanzi angcolile ane-asidi (pH < 6):CI-PAMor I-NPAM isebenza kahle.
- Amanzi angcolile angathathi hlangothi (pH 6–8): Kungasetshenziswa kokubili i-anionic kanye ne-nonionic polyacrylamide.
- Amanzi angcolile ane-alkaline (pH > 8): Kudingeka ukukhetha ngokucophelela; i-anionic PAM ngokuvamile iyathandwa, futhi kudingeka ukulungiswa komthamo.
Ngenxa yokucubungula i-ore, ukumba amanzi angcolile kuvame ukuba ne-asidi, okwenza i-anionic polyacrylamide ibe yisinqumo esivame kakhulu.
Ukusatshalaliswa Kobukhulu Bezinhlayiya Ezilengayo Emanzini Angcolile
Ubukhulu bezinhlayiya ezincane kwenza ukuzinza kube nzima kakhulu.
- Izinhlayiya ezimahhadla: I-polyacrylamide enesisindo sama-molecule esincane inganele.

Isiphetho
Ukukhetha uhlobo lwe-PAM olufanele lokwelashwa kwamanzi amdaka okumba kuyisinqumo sobuchwepheshe esithinta ngqo ukusebenza kahle kokwelashwa, izindleko zokusebenza, kanye nokuhambisana nemvelo. Eziningi zezicelo zamanzi amdaka okumba, i-polyacrylamide enesisindo esikhulu sama-molecule isalokhu iyisinqumo esisetshenziswa kakhulu futhi esisebenzayo, kodwa ukukhetha okuhle kufanele kusekelwe njalo ekuhlolweni kwelabhorethri kanye nokuqinisekiswa kwensimu.
Uma ubhekene nokuchitheka kwenhlabathi okuhamba kancane, ukugcwala kwamanzi amaningi, noma izimo zamanzi angcolile ezishintshashintshayo kakhulu, futhi ufuna umhlinzeki we-PAM othembekile onekhwalithi ehambisanayo kanye nokusekelwa kobuchwepheshe, i-Yuncang iyisinqumo sakho esihle kakhulu.
Sinikeza okungaphezu nje kwamakhemikhali; sihlinzeka ngezixazululo zokucwilisa ezenziwe ngokwezifiso ngokusekelwe ezimweni zakho ezithile zekhwalithi yamanzi. Kungakhathaliseki ukuthi udinga ukwelapha imisele emincane kakhulu, amanzi angcolile anokuqukethwe okuphezulu kodaka, noma izinhlelo ezinokuguquguquka okukhulu kwe-pH, ithimba lethu lobuchwepheshe lingancoma amamodeli omkhiqizo we-PAC ne-PAM, imithamo, kanye namasu okulinganisa ukuqinisekisa ukucwiliswa okusheshayo, amanzi ahlanzekile, kanye nezinqubo ezilula zokulahla udaka ezilandelayo.
Ngokuhlinzeka okuzinzile kanye nokuqonda komkhiqizo ochwepheshe, sizibophezele ekukusizeni ukuthi ufinyelele imiphumela yokwelashwa kwamanzi amdaka eqhubekayo nethembekile, siqinisekisa ukuthi yonke inqwaba ihlangabezana nezindinganiso ezilindelekile.
Xhumana nathi namuhla ukuthola amasampula e-PAM ezidingo zakho zokwelashwa kwamanzi angcolile ezimayini, iseluleko samahhala sokuhlolwa kwe-beaker, kanye nezixazululo ezenziwe ngokwezifiso.
