Dissolved cua flotation tshuab muaj qhov zoo ntawm kev kho mob zoo, yooj yim debugging, thiab kev txuag zog. Xav txog kev txuag nyiaj hauv kev ua haujlwm thiab cov txiaj ntsig, lawv yog qhov kev xaiv zoo tshaj plaws.
Nws tuaj yeem siv los tshem tawm cov impurities xws li algae, plankton, thiab cov xuab zeb los ntawm cov dej nyoos, yog li txhim kho cov dej zoo.
Txheej txheem cej luam ntawm Lub Ntsiab Cai
Lub ntsiab lus ntawm kev ya raws huab cua flotation (DAF) yog siv roj buoyancy cais cov pa phem los ntawm dej. Los ntawm kev qhia cov npuas me me rau hauv cov dej khib nyiab, cov npuas no ua ke nrog cov khib nyiab, roj, colloids, thiab lwm yam kuab paug hauv dej los tsim "flotation cev" nrog qhov ntom tsawg dua dej. Cov cev no sai sai ntab mus rau saum npoo vim buoyancy, tsim ib txheej ntawm scum, uas yog ces tshem tawm los ntawm ib tug scraping system, thaum kawg ua tiav cov dej khib nyiab. Tag nrho cov txheej txheem tuaj yeem muab faib ua tsib kauj ruam tseem ceeb: "gas dissolution - gas tso - adsorption - flotation - sib cais."
Khoom Taw Qhia
Lub tshuab nqus cua flotation (DAF) yog cov khoom tseem ceeb - cov khoom siv sib cais ua kua hauv kev kho dej khib nyiab, tshwj xeeb tsim los tshem tawm cov khoom zoo, cov roj, thiab cov tshuaj colloidal los ntawm dej. Nws siv lub siab - siab yaj cua tshuab, qhov chaw huab cua thiab dej sib xyaw ua ke hauv qab siab los ua cov dej ua kua dej ua kua. Cov dej no tom qab ntawd tso tawm los ntawm cov cuab yeej tso tawm tshwj xeeb, tsim micro- thiab nano- npuas loj. These bubbles, characterized by their high density and uniform dispersion, efficiently adsorb pollutants in the wastewater, allowing for rapid separation at an upward velocity of 20-30 mm/s. Piv nrog rau cov txheej txheem sedimentation ib txwm, qhov kev kho mob tau nce los ntawm 3-5 zaug, thiab kev tshem tawm tus nqi tshem tawm cov khib nyiab (SS) hauv cov dej ntws mus txog ntau dua 95%.

Kev siv cov tshuab flotation
Thaum cov dej khib nyiab muaj cov pa phem xws li cov khib nyiab pov tseg, roj, thiab cov colloids, lub luag haujlwm tseem ceeb ntawm lub tshuab nqus cua ya raws (DAF) yog kom ua tiav cov khoom zoo -kua thiab kua-kua sib cais los ntawm huab cua flotation technology, yog li txo cov load ntawm cov txheej txheem tom qab kho thiab txhim kho cov dej khib nyiab.
n cov ntsiab lus ntawm kev tshem tawm cov khib nyiab pov tseg, ntau cov npuas me me uas tsim los ntawm cov khoom siv hauv cov huab cua yaj (DAF) ua ke nrog cov khoom raug tshem tawm hauv cov dej khib nyiab, tsim " npuas -" particles complexes nrog qhov ntom ntom tsawg dua dej. Cov complexes sai sai ntab mus rau saum npoo, tsim ib txheej ntawm scum. Tom qab raug tshem tawm los ntawm ib tug scraping ntaus ntawv, lub concentration ntawm tshem tawm cov khib nyiab nyob rau hauv cov dej khib nyiab yog ho txo, ua tau raws li qhov xav tau kev tshem tawm cov nyhuv.
Rau kev sib cais cov roj, xws li cov roj ntab, cov npuas tuaj yeem ncaj qha adsorb cov roj tee, nqa lawv mus rau saum npoo thiab ua tiav cov roj sai - dej sib cais.
Rau cov roj emulsified, qhov sib ntxiv ntawm demulsifiers thiab coagulants tuaj yeem rhuav tshem cov roj -dej dispersion system, ua rau cov roj emulsified sib sau ua ke rau hauv cov roj loj dua, uas tom qab ntawd ua ke nrog cov npuas thiab ntab rau saum npoo rau kev sib cais.
Nyob rau hauv rooj plaub ntawm kev tshem tawm colloid, DAF chav tsev tuaj yeem siv cov coagulants thiab flocculants los ua kom tsis muaj zog thiab sib sau cov colloidal hais rau hauv cov flocs loj, uas tom qab ntawd sib xyaw nrog cov npuas me me thiab ntab rau saum npoo kom tshem tawm.
Cov yam ntxwv ntawm huab cua flotation tshuab
High -kev sib cais ua tau zoo thiab kev ua haujlwm ceev ceev
Dissolved air flotation (DAF) systems ua hauj lwm los ntawm kev qhia me me npuas npuas (feem ntau 10-100 μm hauv txoj kab uas hla) rau hauv dej khib nyiab. Cov npuas no nruj nreem khi rau cov pa phem, colloids, thiab roj, tsim "flocculated particles" uas sai sai ntab rau saum npoo vim muaj kev sib tw, yog li ua tiav kev sib cais. Muab piv rau cov txheej txheem sedimentation, cov txheej txheem no nce qhov sib cais ceev los ntawm 3-5 zaug.
01
Ntau yam kev siv thiab muaj zog tshwj xeeb
Rau kev lag luam khoom noj khoom haus, txoj kev no tuaj yeem cais cov roj ntab ntab thiab cov roj emulsified uas nyuaj rau tshem tawm siv cov txheej txheem sedimentation.III. Me me hneev taw thiab siv qhov chaw siab
02
Cov nqi khiav lag luam tsawg thiab kev ua haujlwm yooj yim
Cov cuab yeej muaj cov qauv compact, nyob tsuas yog 1/3 mus rau 1/2 ntawm qhov chaw uas yuav tsum tau ua los ntawm cov txheej txheem sedimentation.
03
Cov dej zoo tshaj plaws thiab cov yam ntxwv zoo sludge
Kev siv cov cua tshuab ua kom muaj txiaj ntsig zoo, kev siv lub zog ntawm ib chav tsev ntim dej tsuas yog 0.3-0.8 kWh / m³.
Kev tu txhua hnub tsuas yog yuav tsum tau tshem tawm cov khib nyiab thiab tshuaj xyuas cov huab cua yaj, ua rau muaj kev ua haujlwm tsawg thiab cov nqi zog tsawg.
