Ukusetshenziswa kwe-polyacrylamide kungenye yezixazululo ezisebenzayo zokuxazulula udaka olunamathelayo. Ukusetshenziswa kahle kwe-Polyacrylamide (PAM), kungathuthukisa kakhulu ukusebenza kokukhipha amanzi kodaka emkhakheni wezimboni, kunciphise izindleko zokusebenza, futhi kuthuthukise ukusebenza kahle kohlelo lonke.
Ukusetshenziswa okulungile kweI-Polyacrylamide(PAM), ingathuthukisa kakhulu ukusebenza kokususwa kwamanzi kodaka emkhakheni wezimboni, inciphise izindleko zokusebenza, futhi ithuthukise ukusebenza kahle kohlelo lonke.
Udaka olunamathelayo lungenye yezinkinga ezinzima kakhulu nezibiza kakhulu ekuhlanzweni kwendle kwezimboni nakomasipala. Kungakhathaliseki ukuthi kuyimboni yamakhemikhali, imboni yokukhiqiza iziphuzo zokudla, imboni yezindwangu noma imboni yokuhlanza indle kamasipala, udaka okunzima ukuluncibilikisa luzokhula kakhulu ekusebenzeni, lunciphise ukusebenza kahle kokucubungula, futhi lubangele izinkinga zokucubungula phansi.
Esinye sezixazululo ezisebenza kahle kakhulu nezisetshenziswa kabanzi kule nkinga yi-polyacrylamide (PAM), i-ejenti yokuhlanganisa esebenza kahle kakhulu eyenzelwe ukuthuthukisa ukususwa kodaka, ukuhlukaniswa kwamanzi kanye noketshezi oluqinile.
Lesi sihloko sizohlola okuqukethwe okulandelayo:
- Yini ebangela ukwakheka kodaka olukhulu?
- Kungani kuyisistimu yokuhlanza indle engcolile
- Indlela yokuxazulula i-PAM
- Umhlahlandlela Wokufaka Isicelo se-PAM
- Imibuzo Evame Ukubuzwa: Ukwelashwa Kodaka Olunamathelayo nge-PAM
Kuyini Udaka Olunamathelayo?
I-sludge enamathelayo ibhekisela ku-sludge enezici ezimbi zokukhipha amanzi, i-viscosity ephezulu, kanye nezakhiwo eziqinile zokunamathela. Ngokuvamile ibonisa:
- Umthamo wokugcina amanzi ophezulu
- Ukuthungwa okufana nejeli noma okushelelayo
- Ukungahlungi kahle
- Ukoma kwekhekhe okuncane ngemva kokukhipha amanzi
- Ukuvala nokungcola kwemishini
Imithombo Evamile Yodaka Olunamathelayo
Udaka olunamathelayo luvame ukuvela ezimbonini ezifana nalezi:
Izimbangela Eziyinhloko
Amaprotheni, amafutha, kanye nama-carbohydrate kwandisa ukujiya kodaka.
Izinto ezengeziwe ze-extracellular polymeric (EPS) ezikhiqizwa amabhaktheriya zakha i-matrix enamathelayo.
Ama-flocculant anganele noma angalingani aholela kuma-floc abuthakathaka noma ancipha kakhulu.
Izinhlayiya zedaka ezineshaja engaphezulu engafanele zivimbela ukuhlangana okuphumelelayo.
Kungani I-Sludge Enamathelayo Iyinkinga
Udaka olunamathelayo lungathinta kakhulu ukusebenza kokwelashwa kwamanzi amdaka:
- Ukunciphisa Ukusebenza Kokukhipha Amanzi Udaka lugcina amanzi engeziwe, okuholela kulokhu: Ukwehla kokuqukethwe kwe-cake solids, ukwanda komthamo wodaka, kanye nezindleko zokulahla eziphezulu.
- Izinkinga Zemishini Ukucindezela kokuhlunga kwebhande kuvaleka kalula, ama-centrifuge alahlekelwa ukusebenza kahle, izindwangu zokuhlunga zidinga ukuhlanzwa njalo.
- Ukusetshenziswa Kwamakhemikhali Okwandayo Ukungaguquguquki kahle kwe-flocculation kuholela emithanjeni ephezulu yamakhemikhali.
- Ukungazinzi Kokusebenza Izakhiwo zodaka ezingaguquguquki zenza kube nzima ukulawula inqubo.
Indlela i-PAM exazulula ngayo izinkinga zodaka olunamathelayo
- Ukungathathi hlangothi kweshaja Udaka olunamathelayo luvame ukuqukethe ama-colloid ashajwe kabi. I-Cationic PAM iqeda lawa ma-charge, ivumela izinhlayiya ukuthi zihlangane.
- Indlela Yokubopha Ama-molecule e-PAM akha amaketanga amade ahlanganisa izinhlayiya eziningi, adale ama-floc amakhulu futhi aqinile.
- Isakhiwo se-Floc Esithuthukisiwe I-PAM ekhethwe kahle ikhiqiza: Ama-floc aminyene, aqinile, ukushuba kodaka okuncishisiwe, ukukhishwa kwamanzi okungcono.
- Ukususwa Kwamanzi Okuthuthukisiwe Ngokulinganisa kwe-PAM okwenziwe ngcono: Izinto eziqinile zekhekhe ziyanda kakhulu, isivinini sokuhlunga siyathuthuka, ivolumu yodaka iyancipha.
Umhlahlandlela Wesinyathelo Ngesinyathelo Wokuxazulula I-Slidge Enamathelayo Nge-PAM
Isinyathelo 1
Isinyathelo sesi-2
Lungisa isisindo sama-molecule ngokusekelwe ezidingweni zosayizi we-floc.
Umthetho Ojwayelekile: Okuqukethwe okuphezulu kwezinto eziphilayo → Ishaja ephezulu.
Ukuhlolwa kwelebhu (ukuhlolwa kwebhodlela) kubalulekile ukuze kukhethwe kahle.
Isinyathelo 3
Ukuthatha umthamo oweqile noma umthamo ongaphansi komthamo kungenza udaka lunamathele kakhulu.
Umthamo ongaphansi komthamo → ama-floc abuthakathaka
Ukweqisa umthamo → ukuzinza kabusha kanye nodaka olushelelayo
Isinyathelo 4
Ukulungiselela okungafanele kunciphisa ukusebenza kahle. Amaphuzu abalulekile:
- Ncibilikisa i-PAM kancane emanzini ahlanzekile
- Sebenzisa ukuhlushwa okungu-0.1–0.3%
- Gwema ukuxubana okunobukhulu obuphezulu
- Vumela isikhathi esanele sokuguga (imizuzu engama-30-60)

Isiphetho
I-sludge enamathelayo iyinkinga eyinkimbinkimbi kodwa engaxazululeka ekuphathweni kwamanzi amdaka. Ngokusetshenziswa kahle kwe-Polyacrylamide (PAM), izimboni zingathuthukisa kakhulu ukusebenza kokukhipha amanzi e-sludge, zinciphise izindleko zokusebenza, futhi zithuthukise ukusebenza kahle kwesistimu iyonke.
Isihluthulelo siseku:
- Ukuqonda izici zodaka
- Ukukhetha uhlobo olufanele lwe-PAM
- Ukuthuthukisa umthamo kanye nesicelo
- Ukuqapha nokulungisa inqubo njalo
Ngokusebenzisa lawa maqhinga, izindawo zokuhlanza amanzi amdaka zingaguqula udaka olunamathelayo, olunzima ukuluphatha lube umkhiqizo olawulekayo nongabizi kakhulu.
Uma unenkinga yokususa amanzi odakeni olunzima, sikunikeza okulandelayo:
- Usekelo lokuhlola imbiza yamahhala
- Izixazululo ze-polyacrylamide ezenziwe ngokwezifiso
- Ukutholakala okuzinzile kokubambisana kwesikhathi eside
ukuthola ikhambi elenzelwe wena futhi uthuthukise ukusebenza kahle kokwelashwa kodaka lwakho.
