Hauv cov txheej txheem dej phwj tuaj, flotation ua si lub luag haujlwm tseem ceeb yog cov khoom lag luam zoo li qub {{}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} kua sib cais tshuab. Qhov tseeb, kev ua haujlwm ua haujlwm ntawm cov flotation tshuab raws li txoj kev flotation. Yog li, cov khoom siv frotation tau siv dav hauv cov dej phwj tuaj kom tshem tawm cov teeb meem ncua, thiab cov nyhuv yog qhov tseem ceeb thiab tuaj yeem ua tau raws li cov kev kho mob tshwj xeeb.
Yog li, yog vim li cas thiaj li yuav ua cov roj frotation siv cov tshuaj frotation zoo tshem tawm cov teeb meem ncua hauv dej?
Lub ntsiab cai tseem ceeb ntawm txoj kev flotation, tseem hu ua txoj kev flotation, yog los tsim kom muaj ntau yam ntawm cov dej sib xyaw, huab cua thiab cov khoom tawg. Nyob rau hauv lub synergistic nyhuv ntawm ntau tus rog xws li interfacial nro, npuas nce buoky thiab hydrostatic siab qhov sib txawv, cov nplais fydrostatic yuav ua raws li cov neeg uas tawg tawm. Txij li qhov ceev ntawm cov nplaum yog tsawg dua li ntawm cov dej, nws yuav ntab mus rau saum npoo av, yog li ua tiav kev sib cais thiab tshem tawm cov impurities hauv dej. Cov txheej txheem frolotation npog cov kauj ruam ntawm npuas tiam, npuas txuas rau cov khoom siv lossis cov kua ua kua, thiab ntab sib cais. Yog li ntawd, ob qhov kev mob tsim nyog yuav tsum tau ua kom tiav Flotation Flocles: Ua ntej, muaj me me ntawm cov dej hla, qhov zoo dua. Qhov zoo tshaj plaws npuas loj feem ntau yog 15-30μm; Thib ob, cov neeg uas raug mob yuav tsum tau muab ncua thiab hydrophobic.
Muab piv nrog cov kev ua kom haum, cov twj tsoos muaj cov yam ntxwv tseem ceeb no:
Cov pa paug dav dav tshem tawm lub peev xwm: Cov pa taws tsis tsuas yog muaj kev tshem tawm zoo rau cov kuab paug uas muaj peev xwm kho tau los ntawm kev ziab.
Cov chaw siv hluav taws xob muaj txiaj ntsig: lub chaw ntawm lub flotation tank yuav tshaj 12 tus dej ntws nyob rau hauv lub tank rau tsuas yog 10-20min, thiab lub tank ib qho tsuas yog 2m. Qhov no ua rau thaj chaw hauv pem teb ntawm cov flotation tank tsuas yog 1 / 2-1 / 8-1 / 8 ntawm lub tank.
Txo cov ntsiab lus scum dej: tus scum uas tsim los ntawm kev tso tawm muaj cov ntsiab lus dej qis dua, feem ntau qis dua 96%. Piv nrog tib qhov hnyav hnyav sludge tsim los ntawm sedimentation, nws ntim yog 2-10 npaug tsawg dua. Qhov no tsis yog yooj yim sludge cov txheej txheem pov tseg, tab sis kuj txuag tau sludge pov tseg cov nqi pov tseg. Ntxiv mus, sludge tshem tawm ntawm qhov chaw flotation yooj yim dua li sludge tso tawm hauv qab ntawm lub tenimentation tank.
Multifunctional dej txhim kho: Ntxiv rau kev tshem tawm cov teeb meem raug tshem tawm, cov khoom siv (flotation) Qhov effluent thiab scum muaj qee qhov ntau ntawm oxygen, uas yog qhov tseem ceeb rau kev kho mob, thiab cov sludge tsis yooj yim rau rot thiab deteriorate.
Tsawg reugent siv: cov qauv flotation siv reagents tsawg dua li cov txheej txheem sedimentation. Thaum tus flocculant yog siv los ua ib tug neeg sawv cev ua si, tus qauv ntawm kev ntxiv cov reagent yog ib qho zoo ib yam li kev kho mob tsis sib xws. Qhov sib txawv yog tias txoj kev flotation tsis tas yuav tsim ib qho loj- qhov chaw uas xav tau lub sijhawm luv luv luv luv. Txawm li cas los xij, cov txheej txheem flotation kuj muaj qhov teeb meem ntawm kev siv hluav taws kub, uas feem ntau {4} · h / m³.
