Umhlahlandlela Ophelele Wokwelashwa Kwamanzi Okuphumelelayo
Izinhlelo zokwelashwa kwamanzi zithembele kakhulu ezinqubweni zokugaya kanye nokuxubana ukuze zisuse izinhlayiya ezilengayo, izinto eziphilayo, kanye nokuthuthumela emanzini. Phakathi kwamakhemikhali asetshenziswa kakhulu kulezi zinqubo kukhonaI-Polyaluminum Chloride (i-PAC)futhiI-Polyacrylamide (i-PAM).
Uma zisetshenziswa ndawonye kahle, i-PAC ne-PAM zingathuthukisa kakhulu ukusebenza kahle kokucwengisisa amanzi, zinciphise umthamo wamakhemikhali, futhi zithuthukise ukusebenza kokuhlanzeka kodaka. Kodwa-ke, ukuhlanganiswa okungafanele—njengokulandelana komthamo okungalungile noma ukuhlushwa—kunganciphisa ukusebenza kahle kokwelashwa.
Lesi sihloko sinikeza umhlahlandlela ophelele wezobuchwepheshe wokuthi ungahlanganisa kanjani i-PAC ne-PAM ekujiyeni, okuhlanganisa izimiso, izindlela zokulinganisa, amasu okwenza ngcono, kanye namaphutha avamile okufanele uwagweme.
Ukuqonda Izindima ze-PAC kanye ne-PAM ekuhlanganisweni kwamangqamuzana
Ngaphambi kokuxoxa ngokuthi ungawahlanganisa kanjani, kubalulekile ukuqonda ukuthi ikhemikhali ngayinye isebenza kanjani enqubweni yokujiya nokuqhuma.
I-Polyaluminum Chlorideiyi-coagulant ye-polymer engakhiqizi esetshenziswa kabanzi ekuphatheni amanzi okuphuza, ekuphatheni amanzi angcolile ezimbonini, kanye nasezinhlelweni zokuthutha indle zikamasipala.
I-PAC isebenza ngokuyinhloko ngokuvimba ukushaja kanye nokumuncwa. Ezinhlelweni eziningi zamanzi zemvelo, izinhlayiya ezilengayo zithwala amacala amabi, azigcina zihlakazekile futhi zivimbele ukuhlala phansi. I-PAC ikhipha ama-ion e-aluminium ashajwe kahle avimbela la macala. Uma esesusiwe, izinhlayiya ziqala ukuhlangana zibe ama-microfloc amancane.
Izinzuzo ze-PAC
- Amandla okujiya aqinile
- Ukususwa kokungcola okusebenzayo
- Ukusebenza kwe-pH ebanzi
- Umthamo wodaka ophansi uma uqhathaniswa nosawoti we-aluminium wendabuko
- Ifanele kokubili ukwelashwa kwamanzi ahlanzekile kanye namanzi angcolile
Kodwa-ke, i-PAC yodwa ingakha ama-floc amancane ahlala kancane, okuyilapho i-PAM iba khona ebalulekile.
I-Polyacrylamideiyi-organic polymer flocculant esetshenziselwa ukuthuthukisa ukugoba kanye nokuhlalisa. I-PAM isebenza ikakhulukazi ngokubopha i-polymer. Amaketanga ayo amade ama-molecule axhumanisa ama-microfloc amaningi ndawonye, akha ama-floc amakhulu naminyene ahlala ngokushesha.
Izinhlobo ze-PAM ezisetshenziswa ekuhlanzweni kwamanzi
Kunezinhlobo ezintathu eziyinhloko:
- I-Anionic PAM (APAM)
- I-Cationic PAM (CPAM)
- I-Nonionic PAM (NPAM)
Ezinhlelweni eziningi ze-PAC + PAM, i-anionic PAM ivame ukusetshenziswa ngoba i-PAC kakade inikeza ukuncishiswa kweshaja okuhle.
Izinzuzo ze-PAM ezinhlelweni zokubopha igazi
- Yandisa usayizi we-floc
- Kusheshisa ukuthuthwa kwenhlabathi
- Kuthuthukisa ukususwa kwamanzi odakeni
- Yehlisa umthamo we-PAC
- Kuthuthukisa ukusebenza kahle kokuhlunga
Kungani i-PAC ne-PAM Zisetshenziswa Ndawonye
Ukusebenzisa i-PAC kanye ne-PAM ndawonye kudala umphumela wokuhlanganisa i-coagulation-flocculation.
Indlela yesinyathelo ngesinyathelo
I-PAC iphazamisa izinhlayiya, inciphisa amashaji, futhi yakha ama-micro-floc.
Amaketanga e-PAM axhumanisa ama-microfloc abe ama-floc amakhulu.
Ama-floc amakhulu acwila ngokushesha emathangini okufaka inhlabathi.
Izinzuzo zokusebenzisa i-polyaluminum chloride ne-polyacrylamide ngokuhlanganiswa
- Ukususwa kokungcola okuphezulu
- Isikhathi sokuxazulula ngokushesha
- Ukusetshenziswa kwamakhemikhali okuphansi
- Umthamo wodaka oncishisiwe
- Ukusebenza kokuhlunga okuthuthukisiwe
Ngenxa yalezi zinzuzo, inhlanganisela ye-PAC + PAM isetshenziswa kabanzi ku:
- Izitshalo zokuhlanza amanzi amdaka zikamasipala
- Ukwelashwa kwamanzi amdaka ezimbonini
- Ukucaciswa kwamanzi amdaka ezimayini
- Ukwelashwa kwamanzi amdaka emshinini wephepha
- Ukucaciswa kwamanzi okuphuza
Ukulandelana Okuqondile Komthamo we-PAC kanye ne-PAM
Esinye sezici ezibaluleke kakhulu ekuqineni kwe-coagulation ngempumelelo ukulandelana kwemithamo. Ukuhleleka okufanele yilokhu:I-PAC kuqala → I-PAM yesibili
Kungani i-PAC kumele ifakwe kuqala
I-PAC kumele iqale inciphise ukushaja kwezinhlayiya bese yakha ama-microflocs okuqala. Ngaphandle kwalesi sinyathelo, ama-molecule e-PAM azomane ancibilike emanzini futhi awakwazi ukubopha izinhlayiya ngempumelelo.
Izinyathelo ezijwayelekile zokulinganisa
- Ithangi lokuxuba elisheshayo
- Umjovo we-PAC
- Ukuxuba okusheshayo (imizuzwana engama-30–60)
- Umjovo we-PAM
- Ukuxubana kancane (isigaba sokugeleza)
- Ukususwa kwenhlabathi
⚠️ Iphutha elivamile:Ukwengeza i-PAM ngaphambi kwe-PAC kuyiphutha elivamile eliholela ekwakhekeni kwe-floc okungekuhle kanye namakhemikhali alahlekile.
Isilinganiso Esifanele Se-PAC Ne-PAM
Umthamo uyahlukahluka kuye ngekhwalithi yamanzi, ukungcoliswa kwamanzi, kanye nokugcwala kwezinto eziqinile ezilengayo.
Amabanga ajwayelekile anjengoba alandelayo
Isilinganiso se-PAC
Amanzi okuphuza: 5–50 mg/L
Amanzi angcolile asezimbonini: 30–200 mg/L
Isilinganiso se-PAM
Ngokuvamile iphansi kakhulu kune-PAC
Ibanga elijwayelekile: 0.1–3 mg/L
Umthetho oyinhloko
Isilinganiso se-PAM ngokuvamile singu-1/100 kuya ku-1/50 sesilinganiso se-PAC.
I-PAM eningi kakhulu ingaholela ku:
- Ama-floc anamathelayo
- Ukuzinza okubi
- Ukuvaleka kwesihlungi
Ngakho-ke, ukuhlolwa kwebhodlela kuyadingeka ukuze kutholakale umthamo ofanele.
Ukulungiselela Izixazululo ze-PAC kanye ne-PAM
Ukulungiswa kwamakhemikhali ngendlela efanele kubalulekile ukuze kuthathwe umthamo ozinzile.
* Ukulungiswa kwesisombululo se-PAC
I-PAC ivame ukulungiswa njengesixazululo esingu-5–10%.
I-PAC iyancibilika ngokushesha futhi ingasetshenziswa ngosuku olufanayo.
*Ukulungiswa kwesisombululo se-PAM
I-PAM idinga ukulungiselela ngokucophelela okukhulu.
Ukuhlushwa okuvamile:
Isixazululo esingu-0.05–0.1%
Ukulungiselela isibonelo:
- Faka amanzi ethangini lokuxuba
- Fafaza kancane kancane i-PAM powder
- Hlanganisa kancane imizuzu engama-30-60
- Vumela ukuguga imizuzu engama-30
Amanothi abalulekile:
- Gwema ukuxuba ngesivinini esikhulu (kungaphula amaketanga e-polymer)
- Sebenzisa amanzi ahlanzekile
- Lungisa ikhambi elisha nsuku zonke
Izimo Ezixubile Zokwenza I-Coagulation Iphumelele
Ukuxuba amandla kuthinta kakhulu ukusebenza kwe-coagulation.
Isigaba sokuxuba ngokushesha
Inhloso: ukusabalalisa i-PAC ngokushesha.
Amapharamitha ajwayelekile:
- Isikhathi: imizuzwana engama-30–60
- I-gradient yejubane (G): 700–1000 s⁻¹
Isigaba sokukhukhuleka
Inhloso: vumela ama-floc akhule ngaphandle kokuphuka.
Amapharamitha ajwayelekile:
- Isikhathi: imizuzu eyi-15–30
- I-gradient yejubane: 20–80 s⁻¹
I-PAM ivame ukungezwa ekuqaleni kwesigaba sokuhamba.
Ukuhlolwa Kwebhodlela Kokuthuthukisa Inqubo
Ukuhlolwa kwe-jar kuyindlela ethembeke kakhulu yokunquma inhlanganisela ye-PAC ne-PAM efanele.
Inqubo yokuhlola imbiza ejwayelekile
- Lungisa amasampula amanzi amaningana
- Engeza imithamo ehlukene ye-PAC
- Ingxube esheshayo
- Engeza i-PAM
- Ingxube ehamba kancane
- Qaphela ukwakheka kwe-floc
- Linganisa ukugcwala ngemva kokuhlala phansi
Okuphawuliwe okubalulekile:
- Usayizi we-Floc
- Isivinini sokuxazulula
- Ukucaca kwamanzi
Umthamo ofanele ukhiqiza:
- Ama-floc amakhulu
- Ukuxazulula ngokushesha
- Amanzi acwebile anamandla
Amaphutha Avamile Lapho Kuhlanganiswa I-PAC Ne-PAM
Ngisho nabasebenzi abanolwazi ngezinye izikhathi bahlangabezana nezinkinga.
Isiphetho
Ukuhlanganisa i-Polyaluminum Chloride ne-Polyacrylamide kungenye yezindlela eziphumelela kakhulu zokuthuthukisa ukujiya kanye nokugoba kwe-flocculation ezinhlelweni zokwelashwa kwamanzi.
I-PAC iphazamisa izinhlayiya ezilengayo ngokuyekisa ukushaja, kuyilapho i-PAM ithuthukisa ukwakheka kwe-floc ngokusebenzisa i-polymer bridge. Uma isetshenziswa ngokulandelana okufanele—kuqala i-PAC, okwesibili i-PAM—la makhemikhali adala ama-floc amakhulu, aminyene ahlala ngokushesha futhi akhiqize amanzi acwebile.
Ukuze kuzuzwe imiphumela emihle kakhulu, opharetha kufanele bagxile ku:
- Ukulandelana okufanele komthamo
- Ukulawula umthamo okunembile
- Ukulungiselela isixazululo esifanele
- Izimo zokuxuba ezilungiselelwe
- Ukuhlolwa kwebhodlela ukuze kulungiswe inqubo
Ngemikhuba efanele yokusebenza, i-PAC ne-PAM zingathuthukisa kakhulu ukusebenza kahle kokwelashwa kwamanzi, ukusebenza kokumiswa kodaka, kanye nokuthembeka kohlelo lonke.
