Katleho ea mocheso o tlase le kalafo ea metsi a tlase a turbidity: ts'ebeliso ea boenjiniere ea ts'ebetso ea ho tlosa polymer iron sulfate turbidity

Lmetsi a nang le mocheso o tlase (mocheso Phekolo ea Metsi ka lebaka la botsitso ba eona bo phahameng ba colloid le katleho e tlase ea flocculation. Ka ferric sulfate ea eona e ikhethang le ho ikamahanya le maemo, polyric sulfate (PFS) e fihletse ts'ebeliso ea katleho lefapheng lena lilemong tsa morao tjena mme e fetohile e 'ngoe ea mahlale a mantlha a ho ntlafatsa sekhahla sa maemo a boleng ba metsi.

1. Mathata a mocheso o tlase le phekolo ea metsi a fokolang a tlaase le melemo ea theknoloji ea PFS

1. Phephetso ea mocheso o tlase le phephetso ea ho hloekisa metsi a tlase

Thibelo ea mocheso o tlase: ho fokotseha ha mocheso oa metsi ho lebisa ho fokotseng matla a limolek'hule tsa kinetic, sekhahla sa hydrolysis sa coagulant se fokotseha ka makhetlo a ka bang 2-4, lihlopha tse entsoeng li hlephile ebile lia fokola, 'me potoloho ea ho rarolla e atolosoa ka 30% -50%.

Tšobotsi e tlaase ea turbidity: khatello e tlaase ea taba e emisitsoeng (

2. Melemo ea mantlha ea tekheniki ea PFS

Litšobotsi tse potlakileng tsa hydrolysis: PFS e ntse e ka ba le hydrolyzed ka potlako ka mocheso o tlase ho hlahisa motsoako o mongata oa hydroxyl (o kang [Fe_3 (OH) _4] ^ {5 +}), o fokotsang ka potlako tefiso e mpe ea sebaka sa colloidal ka tekanyo e phahameng ea tefiso e ntle (ka holimo ho + 30 mV).

Ho matlafatsa borokho ba adsorption: sebopeho sa eona sa ketane ea polymer se ka tšela mokoallo oa matla tikolohong ea mocheso o tlase, ka ho toba adsorb likaroloana tse ntle ho theha palesa e teteaneng ea alum (karolo ea boholo> 1 mm), mme sekhahla sa ho rarolla se eketsoa ka 40% -60% ha se bapisoa le mahlahana a setso.

Synergy of oxidation: trivalent iron ion (Fe³) e ntse e ka oxidize tse ling tse qhibilihang ka har'a lintho tse phelang (joalo ka humic acid) ka mocheso o tlase, o ka tlosoang ka flocculation, 'me sekhahla sa ho tlosa turbidity se eketsoa ka 15% -20%.

2. Maemo a bohlokoa le linyeoe tsa kopo ea boenjiniere

1. Mmasepala Phekolo ea Metsi a Nooang

Semela sa metsi a ka leboea (mocheso oa metsi a tala 4 ℃, turbidity 15 NTU) e sebelisitsoeng PFS ho e-na le polyaluminium chloride (PAC), palo ea ho eketsoa e fokotsehile ho tloha ho 50 mg / L ho ea ho 30 mg / L, nako ea ho rarolla li-catkins e ile ea khutsufatsoa ho tloha metsotso ea 45 ho ea ho metsotso ea 25, 'me fektheri ea metsi a fektheri a fokotseha ho feta 50.0.

2. Mokhoa oa ho potoloha oa metsi oa indasteri

Tšebeliso ea metsi a litšila a hatisang le ho daea hape: tlas'a maemo a ts'ebetso a 10 ℃, PFS le anionic polyacrylamide (AP AM) li sebelisoa hape, sekhahla sa ho tlosa litšila se eketseha ho tloha ho 78% ho ea ho 95%, 'me tlhahiso ea litšila e fokotsehile ka 20%.

Ho lokisoa ha metsi a ultrapure indastering ea elektronike: likaroloana tsa silicon tsa nanoscale (boholo ba likaroloana

3. Leano la ho ntlafatsa boenjiniere le boqapi ba theknoloji

1. Theknoloji e matla ea ho kenya le ho eketsa taolo

Ho ipapisitsoe le sistimi ea tlhahlobo ea mocheso / mocheso oa marang-rang, tokiso e matla ea litekanyetso tsa PFS (10-80 mg/L) e bonoa ho qoba ho putlama ho hoholo le masala a ion a tšepe a bakoang ke keketso e feteletseng.

Taba: Setsi sa ho hloekisa likhoerekhoere se amohetse algorithm ea taolo ea PID e sa utloahaleng, litšenyehelo tsa moemeli li fokotsehile ka 18%, 'me motsoako oa ferric oa li-ion tsa tšepe ka har'a litšila o tsitsitse

2. Motsoako le ts'ebetso ea ho eketsa katleho

PFS + PAM motsoako: ka mor'a ho se nke lehlakore ha motlakase oa PFS, eketsa 0.1-0.5 mg / L APAM matla a flocs a matlafalitsoeng, a loketseng boleng bo tlaase haholo ba metsi a nang le turbidity

Ntlafatso ea pele ho oxidation: potassium permanganate e kopantsoeng (0.2-0.5 mg/L) pele ho oxidation, ho pshatla lera le sireletsang la colloid ea lintho tse phelang mochesong o tlase, 'me tekanyo ea PFS e fokotsehile ka 25%.

3. Ho ikamahanya le maemo a lisebelisoa le ntlafatso ea ho ikamahanya le maemo

Ntlafatso ea motsoako oa li-tubular: ka ho eketsa boleng ba G (> 500s ¹), nako ea ho kopanya e khutsufatsoa ho isa ho metsotsoana e 10, 'me chai ea peanut ea alum e eketseha ka 30%.

Ts'ebetso ea ho kopanya moea oa ho phalla ha khase: setsi sa ho phalla ha moea se qhibilihisitsoeng se eketsoa karolong e ka pele ea tanka ea sedimentation, 'me microflocs (0.2-0.5 mm) e entsoeng ke PFS e matlafatsoa ka makhetlo a mabeli,' me sekhahla sa ho tlosoa ha moferefere se eketseha ka 8% -12%.

4. Moruo oa theknoloji le melemo ea tikoloho

Papiso ea litšenyehelo tsa ts'ebetso: Litsenyehelo tsa ho hloekisa metsi lithane tsa PFS li fokotsehile ka 0.05-0.12 yuan ka tlase ho PAC, seretse se fokotsehile ka 15% -30%, 'me sekhahla sa ho senyeha ha lisebelisoa se fokotsehile ho feta 50%.

Monyetla oa ts'ebetso: Ha ho na litšoaneleho tsa masala a aluminium tse etsang hore e kopane le maemo a metsi a nooang a GB 5749-2022 ho qoba kotsi ea neurotoxicity ea letsoai la setso la aluminium.

5. Tataiso ea ntlafatso ea bokamoso

Nts'etsopele ea sistimi e bohlale ea dosing: bolela esale pele ho fetoha ha boleng ba metsi ho kopantsoeng le mohlala oa ho ithuta ka mochini, le ho hlokomela taolo e ikemetseng le e nepahetseng ea ente ea PFS.

Patlisiso le nts'etsopele ea li-composite agents: ho nts'etsapele tokiso e kopaneng ea PFS e nang le li-enzyme tsa tlhaho le li-nanomaterials ho ntlafatsa matla a ho ts'oara li-nanocolluids tsa mocheso o tlase (

Ka boqapi ba mahlale a boenjiniere, polymer iron sulfate e khothaletsa ho tlola ha mocheso o tlase le kalafo e tlase ea metsi ho tloha "bothata bo tloaelehileng" ho isa "moruo o sebetsang hantle", ho fana ka tšehetso ea mantlha ea tekheniki bakeng sa polokeho ea phepelo ea metsi le ho boloka metsi a indasteri libakeng tse phahameng le tse batang.
