Yuav ua li cas los daws qhov siab turbidity ntawm cov effluent los ntawm Lamella clarifier

Yog vim li cas rau lub siab turbidity ntawm cov effluent los ntawm Lamella clarifier tej zaum yuav raws li nram no

Ua ntej, cov dej xa tawm ntawm qhov nkag tsis sib xws, nyob ze ntawm qhov nkag, cov kua txav tshwm sim loj heev los yog dej ceev, ua rau cov kua hauv zos khiav ceev ntawm qhov nkag loj kom cov sludge tso rau ntawm cov yeeb nkab inclined dua;

2. Qhov tshwm sim ntawm "short flow" tshwm sim hauv zos, uas cuam tshuam rau kev ruaj ntseg ntawm floc thiab ua rau cov floc twb tsim nyob rau hauv lub sij hawm thaum ntxov kom tau yooj yim rov tawg mus rau hauv nplua floc.

3. Yuav kom faib cov dej sib npaug thiab qhib qhov hauv qhov me me, tus nqi ntws los ntawm lub qhov feem ntau loj dua li ntawm advection sedimentation tank, uas ua rau lub thib ob crushing ntawm alum tsim nyob rau hauv thaum ntxov theem, thiab nws yog. yooj yim rau yaug cov av nkos tuag tso rau hauv qab ntawm lub qhov dej faib, uas ua rau muaj qhov nce ntxiv ntawm cov dej ntws tawm.

Kev daws:

1. Lub raj inclined thiab lub dav hlau kab rov tav yog muab tso rau ntawm 60 degree inclination Angle. Ib kab ntawm cov fins tau kos hauv qab txhua lub raj inclined, thiab lub dav hlau kab rov tav tseem nyob ntawm 60 degree inclination Angle. Cov fins ntxiv tuaj yeem txo qis Reynolds tus naj npawb ntawm cov dej ntws thiab txhim kho cov viscosity ntawm cov txheej txheem dej ntws, uas yog qhov tsim nyog rau nag lossis daus. Tsis tas li ntawd, txoj kev deposition ntawm particulate teeb meem yog shortened, thiab cov khoom ntom ntom yog haum rau nag lossis daus.

Ob, xyuas kom cov dej tsis sib xws, perforated paj phab ntsa dej faib, dej faib cheeb tsam thaum pib ntawm kab rov tav ntws tus nqi yuav tsum tswj ntawm {{0}}.010 ~ 0.018m / s.

3. Ib qho chaw tiaj-kho rectifying yog ntxiv rau pem hauv ntej ntawm Lamella clarifier kom cov outflow los ntawm weir tsis tam sim ntawd nkag mus rau hauv inclined tube sedimentation tank, tab sis ua ntej dhau los ntawm lub flat-flow rectifying seem (cov account rau 1/3 ntawm tag nrho ntev ntawm lub tank sedimentation). Txoj kev txhawb nqa ntxiv txhim kho qhov cuam tshuam tsis zoo ntawm lub tank sedimentation thiab txuas ntxiv txo cov kab rov tav ntws tawm, uas tuaj yeem tsis tsuas yog ua lub luag haujlwm ntawm rectifying, tab sis kuj txo qhov nce siab tshaj tawm hauv inclined tube sedimentation tank. Muaj zog cuam tshuam load kuj. Nyob rau tib lub sijhawm, phab ntsa hloov pauv tau ntxiv rau hauv ntu advection thiab ntu cov yeeb nkab inclined, uas ua rau nce siab tshaj ntawm cov yeeb nkab inclined thiab txhim kho cov nag lossis daus.
