Melemo ea 1.Core ea theknoloji ea polymeric iron sulfate decolorization

Coagulation e sebetsang hantle le bokhoni ba decolorization ea polymer iron sulfate (Pfs) hydrolysis ka metsing ho hlahisa multi-core complex (jwalo ka [Fe ₂ (OH) ₃] ³), ka tefiso neutralization, adsorption borokho le matsoelintsoeke, ho tlosoa ka potlako ha likaroloana colloidal le limolek'hule tsa dae tse qhibilihang ka har'a khatiso le ho daea metsi a litšila, le sekhahla sa decolorization ea dae e sebelisitsoeng9% le di-9% can dispersed 9%.

Ntle le decolorization ea ho tlosoa ha litšila tse peli, PFS e ka fokotsa COD ka nako e le 'ngoe (sekhahla sa ho tlosa ho feta 80%) le kakaretso ea phosphorus. Li-catkins tsa iron hydroxide tse hlahisoang ke eona li ka monya li-ion tsa tšepe tse boima le lintho tse phelang, 'me tsa hlokomela tlhoekiso e felletseng ea metsi a litšila.

Ha ho bapisoa le moruo le polokeho ea aluminium coagulant, PFS ha e na kotsi ea masala a aluminium, 'me theko ea thepa e tala e tlaase (ferrous sulfate e le thepa e tala),' me litšenyehelo tsa phekolo ke 20% -50% e tlase ho feta ea mahlahana a setso.

2.Decolorization mochine le likarolo tsa bohlokoa tsa ho laola

Mechanism of action- charge neutralization: PFS hydrolysis products with high positive charge, neutralize the negative charge on the dae colloid, and time time the stability.-Adsorption Bridge: multinuclear complexes connect multiple colloidal particles through molecular chains to form large flocculent settlement.-Chemical complexation: Chemical complexation: iron xy₂ such amino ions (NH). (-OH) le lihlopha tse ling tsa molek'hule ea dae ho fetola ho qhibiliha].

Optimum ho sebetsa maemo-pH mefuta e fapaneng: 6-9 (maemo asiti thibela hydrolysis, alkaline lebisa ho hloleha ha tšepe ion precipitation) -Add concentration: hangata 5% -20% 'mè ​​oa joala e diluted ho 0.2% -0.5% sebetsa mahloriso, e leng ho le bonolo ho etsa hore mmala atolose ho khutlela. chelete].

Lintlha tsa bohlokoa tsa ts'ebeliso ea 3.Engineering le maano a ho ntlafatsa

Tšebelisano Theknoloji ea Kalafo-e kopantsoe le PAM: 0.1-0.3 mg / L anionic polyacrylamide (PAM) e ka fokotsa palo ea PFS ka 30% -50% le ho ntlafatsa ho rarolla li-catkins.-Pre-oxidation process: ozone (0.2 mg / L) kapa potassium permanganate pretreatment e ka senya litlhoko tsa refractory PFS].

Theha mokhoa oa ho laola li-parameter tse ngata: \ [C = 0.78T + 0.15pH-0.08 Temp \] (T ke turbidity, Temp ke mocheso oa metsi), ho finyella ± 10% phoso ea ente].
