Cov nyhuv pretreatment ntawm paddle dosing agitator
Lub paddle dosing agitator yog ib qho khoom siv sib xyaw ua ke hauv cov txheej txheem kho dej, feem ntau yog siv rau kev siv tshuaj thiab sib xyaw ntawm cov tshuaj hauv theem ua ntej. Nws lub luag haujlwm tseem ceeb yog kom ceev thiab sib npaug ntawm cov tshuaj tua kab mob xws li coagulants (xws li polyaluminium chloride, aluminium sulfate, thiab lwm yam), coagulant AIDS lossis pH regulators rau hauv cov dej nyoos kom ua tiav cov tshuaj tiv thaiv lub cev thiab tshuaj lom neeg.
Hauv cov txheej txheem pretreatment, cov dej nyoos feem ntau muaj cov khib nyiab tshem tawm, colloidal hais thiab qee cov kuab paug yaj. Cov kab mob colloidal no sib sib zog nqus vim qhov tsis zoo ntawm lawv qhov chaw thiab tsis yooj yim rau kev sib haum xeeb. Los ntawm kev ntxiv cov coagulants, nws cov nqi saum npoo tuaj yeem nruab nrab thiab nws qhov kev ruaj ntseg tuaj yeem cuam tshuam. Lub paddle agitator ua rau muaj kev kub ntxhov nyob nruab nrab los ntawm qhov qis -ceev rotating paddles, ua kom cov tshuaj sib xyaw ua ke nrog cov dej hauv lub cev hauv lub sijhawm luv luv. Qhov no txhawb kev sib tsoo thiab sib sau ua ke ntawm destabilized colloids, tsim cov flocs me me thiab tso lub hauv paus rau cov txheej txheem tom ntej flocculation thiab sedimentation.
Cov nyhuv pretreatment ntawm paddle agitators yog cuam tshuam los ntawm ntau yam. Ua ntej yog qhov sib zog sib zog (feem ntau ntsuas los ntawm qhov nrawm gradient G tus nqi). Yog tias tus nqi G tsawg dhau lawm, qhov sib tov yuav tsis sib npaug thiab cov tshuaj tiv thaiv ntawm cov reagent yuav tsis txaus. Yog tias tus nqi G siab dhau lawm, nws tuaj yeem rhuav tshem cov flocs uas twb tsim lawm. Tus nqi G hauv qhov sib xyaw ua ke yog tswj ntawm 300 txog 600 s⁻¹, thiab lub sijhawm tshuaj tiv thaiv yog nyob rau hauv 10 mus rau 30 vib nas this. Qhov thib ob, kev tsim thiab kev teeb tsa txoj haujlwm ntawm cov hniav yuav tsum xyuas kom tsis muaj qhov chaw tuag rau kev sib tov, kom cov reagents tuaj yeem ua tiav cov tshuaj tiv thaiv thawj zaug ua ntej nkag mus rau hauv cov tshuaj tiv thaiv tank.
Piv nrog rau lwm yam nplawm cov ntaub ntawv (xws li turbine hom thiab thav duab hom), lub paddle agitator muaj ib tug yooj yim qauv, qis zog noj, yog ib qho yooj yim los tswj, thiab generates nruab nrab shear quab yuam, uas yog conducive rau txoj kev loj hlob ntawm flocs thiab tsis txhob overfragmentation. Yog li ntawd, nws yog dav siv nyob rau hauv me me thiab nruab nrab - cov nroj tsuag dej loj thiab nyob rau hauv cov xwm txheej uas yuav tsum tau siab rau kev tswj ntawm flocs.
Tsis tas li ntawd, paddle- hom dosing agitators feem ntau yog siv ua ke nrog kev siv tshuaj tua kab mob. Lawv tuaj yeem kho qhov ntau npaum ntawm cov tshuaj thiab nplawm qhov tsis sib xws hauv lub sijhawm raws li qhov zoo ntawm cov dej nyoos (xws li turbidity thiab pH), ua tiav kev tswj hwm thiab txhim kho kev ruaj ntseg thiab kev ua haujlwm ntawm pretreatment. Zuag qhia tag nrho, cov cuab yeej no muaj txiaj ntsig zoo tshaj plaws hauv kev txhim kho kev siv tshuaj lom neeg, txhim kho cov dej ntws zoo, thiab ua kom muaj kev ruaj ntseg ntawm cov chav kho mob tom ntej. Nws yog ib qho tseem ceeb ntawm pretreatment units nyob rau hauv niaj hnub kev kho dej systems.
