Polyaluminum Chloride(PAC) yog ib qho tshuaj inorganic polymer coagulant uas siv ntau. Nws cov tsos feem ntau zoo li hmoov daj lossis dawb. Nws muaj qhov zoo ntawm cov nyhuv coagulation zoo heev, cov tshuaj tsawg dua thiab kev ua haujlwm yooj yim. Polyaluminum Chloride yog siv dav hauv kev kho dej kom tshem tawm cov khoom seem, xim, ntxhiab tsw thiab cov hlau ions, thiab lwm yam, thiab tuaj yeem ua kom dej huv zoo. Yuav kom ntseeg tau tias nws ua haujlwm tau zoo thiab muaj kev nyab xeeb thaum siv, yuav tsum ua raws li kev siv thiab khaws cia kom raug.
Yuav Siv PAC Li Cas Hauv Kev Kho Dej
Muaj ob txoj hauv kev tseem ceeb los siv Polyaluminum Chloride. Ib qho yog muab cov khoom ncaj qha rau hauv lub cev dej kom kho, thiab lwm qhov yog teeb tsa nws mus rau hauv cov tshuaj thiab tom qab ntawd siv nws.
Ntxiv ncaj qha: Ntxiv Polyaluminum Chloride ncaj qha rau hauv cov dej uas yuav tsum tau kho, thiab ntxiv raws li qhov ntau npaum li cas tau los ntawm kev sim. Piv txwv li, thaum kho cov dej ntws, Polyaluminum Chloride solids tuaj yeem ntxiv ncaj qha.
Npaj cov tshuaj: Npaj Polyaluminum Chloride rau hauv cov tshuaj raws li qee qhov sib piv, thiab tom qab ntawd ntxiv rau hauv dej kom kho. Thaum npaj cov tshuaj, ua ntej ua kom sov dej kom npau, tom qab ntawd maj mam ntxiv Polyaluminum Chloride thiab do tas li kom txog thaum Polyaluminum Chloride yaj tag. Cov tshuaj uas tau npaj tseg yuav tsum siv tsis pub dhau 24 teev. Txawm hais tias nws ntxiv ib qho txheej txheem ntxiv, qhov tshwm sim zoo dua.
Kev Nyab Xeeb ntawm Kev Siv Polyaluminum Chloride
Kev kuaj lub thawv:Muaj ntau yam tsis paub hauv cov dej phwj. Yuav kom txiav txim siab qhov ntau npaum li cas ntawm flocculant, nws yog ib qho tsim nyog los txiav txim siab tus qauv zoo tshaj plaws ntawm PAM thiab cov khoom noj khoom haus tsim nyog los ntawm kev sim lub thawv.
Tswj tus nqi pH:Thaum siv Polyaluminum Chloride, tus nqi pH ntawm cov dej zoo yuav tsum tau tswj. Rau cov dej khib nyiab acidic, cov tshuaj alkaline yuav tsum tau ntxiv los kho tus nqi PH rau qhov tsim nyog; rau cov dej khib nyiab alkaline, cov tshuaj acidic yuav tsum tau ntxiv los kho tus nqi PH rau qhov tsim nyog. Los ntawm kev kho tus nqi pH, cov nyhuv coagulation ntawm Polyaluminum Chloride tuaj yeem ua tau zoo dua.
Kev Sib Tov thiab Kev Sib Tov:Thaum siv Polyaluminum Chloride, yuav tsum sib tov thiab do kom zoo. Los ntawm kev sib tov los yog kev ua kom muaj pa, Polyaluminum Chloride raug sib cuag tag nrho nrog cov khoom khov thiab cov colloids hauv dej kom tsim cov flocs loj dua, uas ua rau kev sib sau ua ke thiab kev lim dej yooj yim dua. Lub sijhawm sib tov kom zoo feem ntau yog 1-3 feeb, thiab qhov ceev sib tov yog 10-35 r/min.
Ua tib zoo saib xyuas qhov kub ntawm dej:Qhov kub ntawm dej kuj cuam tshuam rau qhov coagulation effect ntawm Polyaluminum Chloride. Feem ntau hais lus, thaum qhov kub ntawm dej qis dua, qhov coagulation effect ntawm polyaluminum chloride yuav qeeb thiab tsis muaj zog; thaum thaum qhov kub ntawm dej siab, qhov cuam tshuam yuav raug txhim kho. Yog li ntawd, thaum siv Polyaluminum Chloride, qhov kub thiab txias tsim nyog yuav tsum tau tswj hwm raws li cov dej zoo.
Kev noj tshuaj raws li qhov tau teem tseg:Thaum siv Polyaluminum Chloride, yuav tsum tau ua tib zoo saib xyuas qhov kev noj tshuaj. Nyob rau hauv ib txwm muaj xwm txheej, Polyaluminum Chloride yuav tsum tau ntxiv rau hauv dej ua ntej ua ntej cov txheej txheem kho tom ntej; yog tias siv ua ke nrog lwm cov neeg sawv cev, kev sib xyaw ua ke tsim nyog yuav tsum tau ua raws li cov khoom siv tshuaj lom neeg thiab cov txheej txheem ntawm kev ua haujlwm ntawm tus neeg sawv cev, thiab koj yuav tsum ua raws li lub hauv paus ntsiab lus ntawm kev ntxiv cov tshuaj coagulant ua ntej thiab tom qab ntawd ntxiv cov tshuaj pab coagulant.
Cov Lus Qhia Txog Kev Khaws Cia PAC Rau Kev Siv Hauv Kev Lag Luam
Khaws cia kom ruaj khov:Yuav kom tsis txhob muaj dej noo nqus thiab oxidation, Polyaluminum Chloride yuav tsum khaws cia rau hauv qhov chaw qhuav, txias, thiab muaj cua nkag tau zoo, thiab khaws lub thawv kom kaw. Tib lub sijhawm, tsis txhob sib xyaw nrog cov tshuaj lom thiab cov tshuaj lom kom tsis txhob muaj kev phom sij.
Cov dej noo-pov thawj thiab tiv thaiv kev sib sau ua ke:Polyaluminum Chloride yooj yim nqus cov dej noo thiab tej zaum yuav sib sau ua ke tom qab khaws cia ntev, cuam tshuam rau kev siv. Yog li ntawd, yuav tsum tau them sai sai rau kev tiv thaiv dej noo thaum khaws cia kom tsis txhob kov ncaj qha rau hauv av. Cov ntaub ntawv tiv thaiv dej noo tuaj yeem siv rau kev cais tawm. Tib lub sijhawm, nws yog qhov tsim nyog los xyuas kom meej tias cov khoom puas sib sau ua ke. Yog tias pom muaj kev sib sau ua ke, nws yuav tsum tau kho raws sijhawm.
Deb ntawm qhov kub:Kev raug tshav ntuj ntev ntev yuav ua rau Polyaluminum Chloride sib sau ua ke thiab cuam tshuam rau kev ua haujlwm ntawm cov khoom; crystallization yuav tshwm sim ntawm qhov kub qis. Yog li ntawd, yuav tsum tsis txhob muaj tshav ntuj ncaj qha thiab kub siab. Tib lub sijhawm, khaws cov cim ceeb toom kev nyab xeeb kom pom tseeb hauv thaj chaw khaws cia.
Kev tshuaj xyuas tsis tu ncua:Yuav tsum tau kuaj xyuas qhov xwm txheej ntawm Polyaluminum Chloride tsis tu ncua. Yog tias pom muaj kev sib sau ua ke, kev hloov pauv xim, thiab lwm yam, yuav tsum tau kho sai sai; tib lub sijhawm, qhov zoo ntawm cov khoom yuav tsum tau kuaj xyuas tsis tu ncua kom ntseeg tau tias nws ua haujlwm ruaj khov.
Ua raws li cov cai kev nyab xeeb:Thaum lub sijhawm khaws cia, koj yuav tsum ua raws li cov cai kev nyab xeeb thiab hnav khaub ncaws tiv thaiv, hnab looj tes thiab lwm yam khoom siv tiv thaiv; tib lub sijhawm, khaws cov cim ceeb toom kev nyab xeeb hauv thaj chaw khaws khoom kom pom tseeb thiab ua raws li cov cai kev nyab xeeb kom tiv thaiv kev raug mob xws li noj tsis raug lossis kov tsis raug.
Polyaluminium chloride yog ib qho khoom siv dav davFlocculant hauv Kev Kho DejYuav kom ntseeg tau tias nws ua tau zoo tshaj plaws thiab muaj kev nyab xeeb, nws yog ib qho tseem ceeb heev uas yuav tsum ua raws li kev siv thiab kev khaws cia kom raug. Los ntawm kev ua raws li cov lus qhia no, koj tuaj yeem ua kom tau txiaj ntsig ntau tshaj plaws ntawm PAC hauv cov khoom siv dej
