PAC raug dej phwj tuaj li cas?

Polyaluminium chloride(PAC) yog cov coagulant feem ntau siv nyob rau hauv kev kho dej kom muaj flocculate tshem tawm cov nplais, suav nrog cov uas pom hauv dej phwj tuaj. Flocculation yog txheej txheem uas cov khoom me me hauv cov dej sib xyaw ua ke los tsim cov khoom loj dua, uas tuaj yeem tshem tawm cov dej yooj yim dua.

Ntawm no yog li cas PAC tuaj yeem siv rau flocculate dej phwj tuaj:

Kev npaj ntawm PAC daws:PAC feem ntau muab rau hauv cov kua lossis hmoov. Thawj kauj ruam yog los npaj kev daws teeb meem ntawm PAC los ntawm kev ua kom cov hmoov lossis ua kom cov kua ua kua hauv dej. Cov concentration ntawm PAC hauv kev daws yuav muaj kev cai raws li cov cai muaj ntawm cov txheej txheem kev kho mob.

Nws:TusPacKev daws yog tom qab ntawd tov nrog cov dej phwj tuaj. Qhov no tuaj yeem ua tau nyob rau hauv ntau txoj kev nyob ntawm kev teeb tsa ntawm cov chaw kho mob. Feem ntau, cov tshuaj PAC tau ntxiv rau qhov sludge nyob rau hauv lub tank sib xyaw lossis los ntawm kev siv tshuaj pleev ib ce.

Coagulation:Thaum lub pac daws teeb meem nrog sludge, nws pib ua raws li ib tug coagulant. PAC ua haujlwm los ntawm nruab nrab cov nqi tsis zoo ntawm cov ntawv raug tshem tawm hauv sludge, cia lawv tuaj ua ke thiab tsim cov qoob loo loj dua.

Flocculation:Raws li lub pac-kho sludge undlees maj stirring lossis sib xyaw, cov kev tawm tsam needalized pib los ua ke los ua cov flocs. Cov flucs loj dua li cov khoom hnyav thiab hnyav dua li cov neeg, ua rau lawv yooj yim los khom lossis cais tawm ntawm theem ua kua.

CEDLING:Tom qab flocculation, cov sludge tau tso cai rau khom lub tank tank lossis clarIlier. Cov flocs loj dua mus rau hauv qab ntawm lub tank hauv qab ntawm kev cuam tshuam ntawm kev sib tsoo, tawm tom qab cov dej qab los ntawm sab saum toj.

Sib cais:Thaum lub sijhawm teeb tsa tau ua tiav, cov dej kom pom tseeb los yog nqus tawm sab saum toj ntawm lub tank tank rau kev kho mob ntxiv lossis tawm. Qhov kev txiav txim siab sludge, tam sim no denser thiab ntau dua compact vim flocculation, tuaj yeem tshem tawm hauv qab ntawm lub tank rau kev ua ntxiv lossis pov tseg.

Nws yog ib qho tseem ceeb kom nco ntsoov tias qhov ua tau zoo ntawm PAC hauvFlocculating dej phwj tuaj sludgeMuaj peev xwm nyob ntawm ntau yam xws li cov concentration ntawm PAC siv, PH ntawm sludge, ntsuas ntawm cov kab mob ntawm sludge nws tus kheej. Kev ua kom zoo ntawm cov kev ua kom zoo yog feem ntau ua tiav los ntawm kev kuaj sim thiab sim kev sim siab kom ua tiav cov txiaj ntsig xav tau. Tsis tas li ntawd, tsim nyog tuav thiab koob tshuaj ntawm PAC yog qhov tseem ceeb kom ntseeg tau tias muaj txiaj ntsig zoo thiab kev ua haujlwm tau zoo ntawm dej phwj tuaj.
