Yuav ua li cas PAC flocculate dej sludge?

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

Nov yog li cas PAC tuaj yeem siv los ua cov dej phwj tuaj sludge:

Kev npaj PAC kev daws teeb meem:PAC feem ntau yog muab rau hauv cov kua lossis hmoov.Thawj kauj ruam yog los npaj ib qho kev daws ntawm PAC los ntawm kev muab cov hmoov sib tov los yog diluting cov kua hauv dej.Qhov concentration ntawm PAC nyob rau hauv cov tshuaj yuav nyob ntawm seb cov kev cai tshwj xeeb ntawm cov txheej txheem kho.

Kev sib xyaw:CovPACtom qab ntawd cov tshuaj yog tov nrog cov dej phwj tuaj sludge.Qhov no tuaj yeem ua tau ntau yam nyob ntawm qhov teeb tsa ntawm qhov chaw kho mob.Feem ntau, cov tshuaj PAC tau ntxiv rau cov sludge hauv lub tank sib xyaw lossis los ntawm kev siv tshuaj.

Coagulation:Thaum cov tshuaj PAC tov nrog cov sludge, nws pib ua raws li coagulant.PAC ua haujlwm los ntawm nruab nrab cov nqi tsis zoo ntawm cov khoom raug tshem tawm hauv cov sludge, tso cai rau lawv los ua ke thiab tsim cov khoom loj dua.

Flocculation:Raws li PAC-kho sludge undergoes maj nplawm los yog sib tov, cov khoom nruab nrab pib tuaj ua ke los tsim flocs.Cov flocs no loj dua thiab hnyav dua li ib tus neeg, ua rau lawv yooj yim dua los khom lossis cais tawm ntawm cov kua theem.

Kev daws teeb meem:Tom qab flocculation, cov sludge raug tso cai nyob rau hauv ib lub tank los yog clarifier.Cov flocs loj dua nyob rau hauv qab ntawm lub tank nyob rau hauv lub zog ntawm lub ntiajteb txawj nqus, tawm hauv qab clarified dej rau saum.

Kev sib cais:Thaum cov txheej txheem daws tiav lawm, cov dej ntshiab tuaj yeem muab tshem tawm lossis tso tawm rau saum lub tank rau kev kho mob ntxiv lossis tso tawm.Cov sludge nyob, tam sim no denser thiab ntau compact vim flocculation, tuaj yeem raug tshem tawm hauv qab ntawm lub tank rau kev ua haujlwm ntxiv lossis pov tseg.

Nws yog ib qho tseem ceeb kom nco ntsoov tias qhov ua tau zoo ntawm PAC hauvflocculating dej phwj sludgetuaj yeem nyob ntawm ntau yam xws li cov concentration ntawm PAC siv, pH ntawm cov sludge, kub, thiab cov yam ntxwv ntawm cov sludge nws tus kheej.Kev ua kom zoo ntawm cov kev ntsuas no feem ntau yog ua los ntawm kev sim kuaj thiab kev sim ntsuas ntsuas kom ua tiav cov txiaj ntsig kev kho mob xav tau.Tsis tas li ntawd, kev tuav thiab siv cov PAC kom zoo yog qhov tseem ceeb los xyuas kom muaj txiaj ntsig zoo thiab raug nqi kho cov dej phwj tuaj.
