Hauv ntiaj teb kev kho dej, kev tsim kho tshiab ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev noj qab haus huv pej xeem thiab kev tiv thaiv ib puag ncig.Polyaluminum chloride, feem ntau hu ua PAC, tau tshwm sim los ua ib qho kev daws teeb meem muaj zog nrog ntau yam kev ua haujlwm thiab kev siv, hloov pauv txoj hauv kev uas peb ntxuav thiab tswj cov peev txheej dej. Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov haujlwm thiab kev siv ntawm PAC, qhia txog nws qhov tseem ceeb hauv kev kho dej.
Polyaluminum chloride yog ib hom tshuaj lom neeg uas feem ntau siv los ua cov coagulant thiab flocculant hauv cov txheej txheem kho dej. Nws yog synthesized los ntawm cov tshuaj tiv thaiv ntawm aluminium hydroxide thiab hydrochloric acid, ua rau muaj cov tshuaj ntxuav dej uas siv tau ntau yam thiab ua haujlwm tau zoo. PAC muaj ntau hom, suav nrog kua thiab khoom, ua rau nws hloov tau rau ntau yam kev siv.
Cov Haujlwm ntawm PAC
Kev Coagulation thiab Flocculation: Ib qho ntawm cov haujlwm tseem ceeb ntawm PAC yog coagulation thiab flocculation. Thaum muab tso rau hauv dej, PAC tsim cov flocs txhuas hydroxide uas muaj nqi zoo. Cov flocs no nyiam thiab tshem tawm cov khoom me me thiab cov khoom tsis huv hauv dej, xws li cov khoom khov kho, cov khoom siv organic, thiab txawm tias qee yam kab mob me me. Thaum cov flocs loj hlob tuaj, lawv nyob hauv qab ntawm lub tank kho, ua rau nws yooj yim dua los tshem tawm cov khoom tsis huv ntawm cov dej.
Kev Kho pH: PAC tuaj yeem pab kho qhov pH ntawm dej. Los ntawm kev ntxiv PAC, pH ntawm cov dej acidic lossis alkaline tuaj yeem coj mus rau hauv qhov ntau yam xav tau, kom ntseeg tau tias cov txheej txheem kho tom qab ntawd ua haujlwm tau zoo.
Txo Qhov Tsaus Ntuj: Qhov tsaus ntuj, uas tshwm sim los ntawm cov khoom me me uas dai, tuaj yeem ua rau dej zoo li tsaus ntuj thiab tsis zoo nkauj. PAC tuaj yeem txo qhov tsaus ntuj tau zoo los ntawm kev sib sau ua ke cov khoom me me uas dai, ua rau lawv poob rau hauv qab.
Kev Tshem Tawm Hlau Hnyav: PAC muaj peev xwm tshem tawm cov hlau hnyav ntawm dej, xws li arsenic, lead, thiab mercury, los ntawm cov txheej txheem hu ua adsorption. Cov flocs aluminium hydroxide uas muaj cov nqi positively nyiam thiab khi nrog cov ions hlau hnyav uas muaj nqi negatively, ua rau lawv yooj yim tshem tawm.
Kev Siv Ntau Yam ntawm PAC
Kev Kho Dej Hauv Nroog: PAC siv dav hauv cov chaw kho dej hauv nroog los ntxuav dej haus. Nws pab tshem tawm cov khoom tsis huv, txhim kho kev ntshiab ntawm dej, thiab xyuas kom meej tias cov dej ua tau raws li cov qauv kev cai rau kev haus kom muaj kev nyab xeeb.
Kev Siv Hauv Kev Lag Luam: Ntau lub lag luam vam khom PAC rau lawv cov kev xav tau kev kho dej. Txij li kev kho cov dej khib nyiab hauv kev lag luam tshuaj mus rau kev ntxuav cov dej txias hauv cov chaw tsim hluav taws xob, PAC ua lub luag haujlwm tseem ceeb hauv kev tswj hwm kev ua haujlwm zoo thiab kev ua raws li ib puag ncig.
Kev Khawb Av thiab Kev Ua Cov Khoom Siv Pob Zeb: Hauv kev khawb av thiab kev ua cov khoom siv pob zeb, PAC yog siv los cais cov khoom siv muaj nqis ntawm cov khoom tsis huv uas tsis xav tau. Nws lub peev xwm los ua kom cov khoom khov thiab ua rau nws yog ib qho cuab yeej tseem ceeb hauv kev lag luam.
Kev Lag Luam Ntawv thiab Pulp: PAC siv rau hauv kev lag luam ntawv thiab pulp los pab ua kom cov dej ua haujlwm huv si, ua rau cov ntawv zoo dua thiab txo qhov cuam tshuam rau ib puag ncig.
Kev Lag Luam Textile: Cov chaw tsim khoom siv PAC los kho cov dej khib nyiab uas muaj cov xim pleev thiab lwm yam khoom tsis huv. Cov khoom siv coagulation thiab flocculation ntawm PAC pab tshem tawm cov xim thiab cov khoom khov, ua rau muaj kev nyab xeeb rau kev tso tawm lossis rov siv dua cov dej.
Polyaluminum chloride, lossis PAC, tau ua pov thawj tias nws yog ib qho kev daws teeb meem uas siv tau ntau yam thiab tseem ceeb hauv ntiaj teb kev kho dej. Nws cov haujlwm hauv kev coagulation, flocculation, pH kho, turbidity txo, thiab tshem tawm cov hlau hnyav tau ua rau nws yog tus neeg ua si tseem ceeb hauv kev ua kom muaj kev nkag mus rau dej nyab xeeb thiab huv rau cov zej zog thiab cov lag luam ib yam. Raws li qhov tseem ceeb ntawm qhov zoo ntawm dej thiab kev ruaj khov ib puag ncig txuas ntxiv nce ntxiv, qhov tseem ceeb ntawm PAC hauvtshuaj kho dejtau teeb tsa kom sawv, ua rau nws yog ib qho cuab yeej tseem ceeb hauv kev ua tiav lub neej yav tom ntej noj qab haus huv thiab ruaj khov dua.
