► 2. Equipment Selection Analysis for Sedimentation Process
► 2.1 Technical Comparison of Sedimentation Tank Hom
Cov theem sedimentation bears lub luag haujlwm ntawm kev cais cov khib nyiab tshem tawm ntawm dej. Qhov kev ua tau zoo ntawm peb hom kev ua dej xau tank muaj qhov sib txawv:
|
Sedimentation Tank Hom |
Cov yam ntxwv zoo |
Kev kho mob zoo |
Hneev taw |
|
Kab rov tav Flow Tank (Rectangular) |
Cov qauv yooj yim, kev ua haujlwm ruaj khov |
Nruab nrab |
Loj |

Inclined Tube Settler (Lamella) |
Ntxiv sedimentation cheeb tsam, txhim kho efficiency |
Kwv tij siab |
Me me |
|
High -Density Clarifier |
Combines sludge rov qab, txhim kho kev kho mob |
Siab |
Nruab nrab |
Inclined tube settlers tuaj yeem kho cov dej ntim loj dua nyob rau hauv tib lub hneev taw los ntawm kev ua kom thaj chaw zoo sedimentation. High-cov ntaub ntawv ceev ceev yog qhov tsim nyog rau cov xwm txheej uas cov dej nyoos turbidity fluctuates heev, thiab lawv cov sludge rov qab mechanism tuaj yeem txhim kho tag nrho cov kev kho mob.
► 3. Core Technology Analysis of Filtration Process
► 3.1 Kev Ua Haujlwm Sib txawv ntawm Cov Lim Sai Sai thiab V-Cov Lim Lim
Cov theem pom yog qhov teeb meem tseem ceeb los xyuas kom meej cov dej tsis zoo.Hauv cov thev naus laus zis niaj hnub pom, cov ntxaij lim dej nrawm nrawm thiab V- hom lim yog ob txoj kev xaiv.Cov ntxaij lim dej nrawm nrawm muaj cov qauv yooj yim thiab tus nqi qis, tsim nyog rau cov haujlwm nrog cov kev xav tau xoob xoob rau cov dej ntws zoo. V- hom lim siv homogeneous lim xov xwm nrog kev ua kom rov qab zoo dua, muaj peev xwm tswj xyuas qhov pom kev ruaj khov dua.Nyob rau hauv niaj hnub kev kho dej systems, ua ke nrog advanced dej ultrafiltration technology, pom precision thiab kev kho mob efficiency tau loj hlob.
