Ukuze ukhiphe noma usebenzise kabusha Indle ngemva Kokwelashwa, izinhlobonhlobo Zamakhemikhali zidinga ukusetshenziswa enqubweni Yokuhlanza Indle.Namuhla,Abahlinzeki be-PAM (Polyacrylamide).uzokutshela ngama-flocculants:
I-Flocculant: Ngezinye izikhathi ebizwa nangokuthi i-coagulant, ingasetshenziswa njengendlela yokuqinisa ukuhlukaniswa koketshezi oluqinile, futhi ingasetshenziswa ethangini lokuhlala eliyisisekelo, ithangi lokuhlala lesibili, ithangi le-flotation, ukwelashwa okuphakeme noma ukwelashwa okuthuthukisiwe nezinye izixhumanisi zenqubo.
Ama-flocculants asetshenziswa njengendlela yokuqinisa ukuhlukaniswa okuqinile-uketshezi emkhakheni wokuhlanza indle.Zingasetshenziselwa ukuqinisa ukuthululwa kwendle okuyinhloko, ukwelashwa kwe-flotation kanye ne-sedimentation yesibili ngemva kwenqubo ye-sludge ecushiwe, futhi ingasetshenziselwa ukwelashwa okuphakeme noma ukwelashwa okuthuthukisiwe kwendle.Uma isetshenziselwa ukulungisa ngaphambi kokuphelelwa amanzi emzimbeni kodaka oludlulele, ama-flocculants nama-coagulant aba yizimo ze-sludge noma ama-ejenti aqeda amanzi emzimbeni.
Uma usebenzisa ama-flocculants endabuko, indlela yokwengeza izinsiza ze-coagulant ingasetshenziswa ukuthuthukisa umphumela we-flocculation.Isibonelo, ukusebenzisa i-asilicic acid ecushiwe njenge-coagulant flocculants ye-inorganic flocculants njenge-ferrous sulfate ne-aluminium sulfate futhi ukungeza ngokulandelana kungazuza ukugeleza okuhle.Ngakho-ke, ngokwemibandela ye-layman, i-inorganic polymer flocculant IPF empeleni ilungiswa ngokuhlanganisa i-coagulant aid kanye ne-flocculant bese ihlanganiswa ndawonye ukuze kube lula ukusebenza komsebenzisi.
Ukwelashwa kwe-coagulation kuvame ukubekwa phambi kwesikhungo sokuhlukanisa uketshezi oluqinile, futhi kuhlanganiswe nendawo yokuhlukanisa, kungasusa ngempumelelo izinto eziqinile ezimisiwe kanye nezinto eziqinile ezinosayizi wezinhlayiyana ze-1nm kuya ku-100μm emanzini aluhlaza, kunciphise ukuqubuka kwamanzi angcolile kanye ne-CODCr, futhi ingasetshenziswa ekwenziweni kwangaphambili kwezinqubo zokuhlanza indle.Ukwelashwa, ukwelashwa okuthuthukisiwe, nakho kungasetshenziselwa ukwelashwa kodaka olusele.Ukwelashwa kwe-coagulation nakho kungasusa ngempumelelo ama-microorganisms kanye namagciwane e-pathogenic emanzini, futhi kususe amafutha e-emulsified, i-chroma, i-ion yensimbi esindayo kanye nezinye izinto ezingcolisa indle.Izinga lokususwa kwe-phosphorus equkethwe endle lingase libe phezulu ku-90% lapho i-coagulation sedimentation isetshenziselwa ukwelapha i-phosphorus.~95%, iyindlela eshibhile nesebenza kahle kakhulu yokususa i-phosphorus.
Enqubweni yokuhlanza indle, amanye ama-agent azosetshenziswa.Namuhla, iI-PAM Manufacturerwethula eyodwa kuphela yazo.Usayaqonda?Naka i-Yuncang futhi ukuphendule ulwazi olwengeziwe lokuhlanza indle!
