Polyaluminium chloride(PAC) yog ib qho kev sib xyaw ua ke hauv cov pa hluav taws polymer coagulant. Nws cov tsos feem ntau tshwm yog xim daj lossis dawb. Nws muaj qhov zoo ntawm kev ua haujlwm zoo heev, txo qis thiab kev lag luam yooj yim. Polyaluminium chloride yog dav siv nyob rau hauv lub tshav teb kev kho mob kom tshem tawm cov khib nyiab, xim, ntxhiab thiab lwm yam. Txhawm rau kom ntseeg tau tias nws cov hauj lwm ua tau zoo thiab kev nyab xeeb thaum siv, kho cov kev pab kho thiab yuav tsum tau ua raws.
Kev siv ntawm PAC
Muaj ob txoj hauv kev los siv polyaluminum tshuaj tov. Ib qho yog kom ncaj qha muab cov khoom lag luam rau hauv lub cev dej kom raug kho, thiab lwm qhov yog los kho nws mus rau hauv kev daws teeb meem thiab tom qab ntawd siv nws.
Ib qho ntxiv ntxiv: ntxiv polyaluminum tshuaj chloride ncaj qha rau cov dej yuav tsum tau kho, thiab ntxiv nws raws li kev ntsuas zoo. Piv txwv li, thaum kho cov dej dej, polyaluminum tshuaj yeeb tshuaj yeeb tshuaj tuaj yeem ntxiv ncaj qha.
Npaj cov kev daws: Npaj polyaluminum chloride rau hauv kev daws raws li kev sib faib ua feem, thiab tom qab ntawd ntxiv rau cov dej kom raug kho. Thaum npaj cov kev daws teeb meem, ua ntej ua kom sov dej kom npau npau, tom qab qeeb ntxiv ntxiv polyaluminum chloride thiab do tas mus li kom txog rau thaum polyaluminum chloride yog yaj tag nrho. Cov kev npaj daws teeb meem yuav tsum siv tsis pub dhau 24 teev. Txawm hais tias nws ntxiv ib txheej txheem ntxiv, cov nyhuv yog qhov zoo dua.
Cov kev ceev faj
HLUB HLUAS:Muaj ntau yam tsis paub hauv qab zib. Txhawm rau txiav txim siab ntau npaum li cas ntawm flocculant, nws yog qhov tsim nyog los txiav txim siab tus qauv zoo tshaj plaws ntawm PAM thiab cov khoom lag luam tsim nyog los ntawm kev sim ntawm JART.
Tswj tus nqi pH:Thaum siv polyaluminum chloride, tus nqi ntawm cov dej tsis zoo yuav tsum tau tswj hwm. Rau acidic wastewater, alkaline cov tshuaj yuav tsum tau ntxiv los kho tus nqi pH kom tsim nyog; Rau Alkaline Wastewater, acidic tshuaj yuav tsum tau ntxiv los kho tus nqi pH kom tsim nyog. Los ntawm kev kho tus nqi pH, cov txiaj ntsig sib thooj ntawm polyaluminum tshuaj chloride tuaj yeem zoo dua qub.
Sib tov thiab nplawm:Kev sib xyaw kom zoo thiab nplawm yuav tsum tau ua thaum siv polyaluminum chloride. Los ntawm cov neeg kho tshuab nplawm los yog nceration, polyaluminum chloride yog tag nrho cov dej tshem tawm thiab cov colloids hauv cov flocs loj, uas ua kom yooj yim thiab pom kev. Lub sijhawm tsim nyog stirring yog feem ntau 1-3 feeb, thiab qhov nplawm nrawm yog 10-35 r / min.
Them sai sai rau dej kub:Cov dej kub tseem cuam tshuam rau kev cuam tshuam sib txawv ntawm polyaluminum chloride. Feem ntau hais lus, thaum dej kub qis dua, qhov sib txawv ntawm polyaluminum chloride yuav qeeb thiab tsis muaj zog; Thaum thaum lub sijhawm dej kub siab dua, cov nyhuv yuav ua kom zoo dua. Yog li ntawd, thaum siv polyaluminum chloride, qhov ntsuas qhov ntsuas tau nyog yuav tsum tau tswj raws li dej ua kom zoo.
Dosing Sequence:Thaum siv polyaluminum chloride, kev saib xyuas yuav tsum tau them rau txoj kev noj tshuaj ua ntu zus. Nyob rau hauv ib txwm muaj xwm txheej, polyaluminum chloride yuav tsum tau muab ntxiv rau cov dej ua ntej ua ntej cov txheej txheem kho mob ntxiv; Yog tias siv ua ke nrog cov neeg sawv cev ua ke, cov tshuab ntawm kev ua ntawm tus neeg saib xyuas, thiab koj yuav tsum ua raws li cov hauv paus ntsiab lus ntawm kev ntxiv cov kev pab cuam tshuam ua ntej thiab tom qab ntawd ntxiv cov pa sib pab.
Cia Txoj Kev
Muab ntim cia:Txhawm rau kom tsis txhob nqus dej noo thiab oxidation, polyaluminium chloride yuav tsum tau muab cia rau hauv qhov chaw qhuav, txias, muaj qhov cua txias, thiab khaws lub thawv ntim. Nyob rau tib lub sijhawm, zam kev sib xyaw nrog cov tshuaj lom thiab cov tshuaj tua tsis taus kom tsis txhob muaj kev phom sij.
Yo noo-pov thawj thiab anti-Caking:Polyaluminium chloride yooj yim nqus dej noo thiab tej zaum agglomerate tom qab sij hawm ntev, cuam tshuam rau kev siv cov nyhuv. Yog li ntawd, kev saib xyuas yuav tsum tau them rau cov dej noo-pov thawj thaum lub sijhawm khaws cia kom tsis txhob sib cuag nrog hauv av. Cov ntaub ntawv muaj dej noo tuaj yeem siv rau kev rho tawm. Nyob rau tib lub sijhawm, nws yog qhov tsim nyog los kuaj seb cov khoom yog agglomerated. Yog hais tias agglomeration yog pom, nws yuav tsum tau hais txog nyob rau hauv lub sijhawm.
Deb ntawm rhuab:Ntev mus rau lub hnub ci yuav ua rau polyaluminum chloride clumping thiab cuam tshuam cov khoom lag luam; Crystallization yuav tshwm sim ntawm tsawg kub. Yog li ntawd ncaj qha tshav ntuj thiab qhov kub yuav tsum tau zam. Nyob rau tib lub sijhawm, kom muaj kev nyab xeeb ceeb toom cov cim qhia meej meej pom hauv thaj chaw cia.
Kev soj ntsuam tsis tu ncua:Qhov chaw cia ntawm polyaluminum chloride yuav tsum tau kuaj xyuas tsis tu ncua. Yog hais tias agglomeration, discoloration, thiab lwm yam tau pom, nws yuav tsum tau hais txog nrog sai sai; Nyob rau tib lub sijhawm, qhov zoo ntawm cov khoom yuav tsum tau raug kuaj kom ntseeg tau tias nws ua tau ruaj khov.
Ua raws cov kev nyab xeeb kev cai:Thaum lub sijhawm khaws cia, koj yuav tsum ua raws li kev tswj hwm kev nyab xeeb thiab hnav cov khaub ncaws tiv thaiv, hnab looj tes thiab lwm yam khoom muaj kev tiv thaiv; Nyob rau tib lub sijhawm, khaws cov paib ceeb toom kev nyab xeeb hauv thaj chaw cia pom kom pom tseeb thiab ua raws cov kev nyab xeeb kom tiv thaiv kev sib tsoo xws li kev sib tsoo ntawm kev sib tsoo.
Polyaluminium chloride yog siv davFlocculant nyob rau hauv kev kho dejCov. Txhawm rau kom ntseeg tau nws qhov kev ua tau zoo thiab kev nyab xeeb, nws yog qhov tseem ceeb rau kev siv tau thiab kev khaws cia. Los ntawm kev ua raws li cov lus qhia no, koj tuaj yeem ua kom cov txiaj ntsig ntawm PAC hauv cov dej trota
