DAFyaj cua flotationmuaj flotation tank, yaj cua system, reflux yeeb nkab, yaj cua tso tawm system, skimmer (Raws li cov neeg xav tau kev pab, muaj kev sib xyaw hom, mus txawv tebchaws hom thiab saw-phaj hom xaiv.), hluav taws xob txee thiab lwm yam.
Huab cua flotation sib cais tshuab ntawm Benenv DAFyaj cua flotationdissolves huab cua rau hauv dej ntawm qee qhov kev ua haujlwm siab.Nyob rau hauv tus txheej txheem, cov dej pressurized yog saturated nrog yaj huab cua thiab tawm mus rau hauv ib lub nkoj flotation.Cov cua tshuab microscopic uas tsim los ntawm cov cua tso tawm txuas rau cov khib nyiab thiab ntab rau saum npoo, tsim ib daim pam sludge.Ib rab diav tshem tawm cov thickened sludge.Thaum kawg, nws ua tiav purifies cov dej.
Huab cua flotation thev naus laus zis ntawm DAF yaj huab cua flotation plays lub luag haujlwm tseem ceeb hauv kev sib cais cov kua dej (ib txhij txo COD, BOD, chroma, thiab lwm yam).Ua ntej, sib tov flocculating tus neeg sawv cev rau hauv dej nyoos thiab do kom huv si.Tom qab lub sijhawm khaws cia tau zoo (lab txiav txim siab lub sijhawm, ntau npaum li cas thiab cov nyhuv flocculation), cov dej nyoos nkag mus rau hauv thaj chaw tiv tauj uas cov huab cua microscopic ua raws li floc thiab tom qab ntawd ntws mus rau hauv thaj chaw sib cais.Nyob rau hauv cov teebmeem buoyancy, cov npuas me me ntab cov flocs rau saum npoo, tsim ib daim pam sludge.Cov khoom siv skimming tshem tawm cov sludge mus rau hauv lub sludge hopper.Tom qab ntawd cov dej ntshiab qis ntws mus rau hauv cov dej huv-dej reservoir los ntawm cov yeeb nkab sau.Qee cov dej tau rov ua dua tshiab rau lub flotation tank rau huab cua dissolving system, thaum lwm tus yuav raug tso tawm.
