Poly Aluminium Chloride ua haujlwm li cas?

Hauv ntiaj teb kev kho dej,Poly Aluminium Chloride(PAC) tau tshwm sim los ua ntau yam thiab muaj txiaj ntsig coagulant.Nrog nws txoj kev siv dav hauv kev ntxuav cov dej haus thiab cov chaw kho dej khib nyiab, PAC tab tom ua nthwv dej rau nws lub peev xwm zoo tshaj plaws los qhia meej dej thiab tshem tawm cov kab mob.Hauv tsab xov xwm no, peb qhia txog kev ua haujlwm ntawm PAC thiab nws qhov tseem ceeb hauv kev kho dej.

Chemistry Qab PAC:

Poly Aluminum Chloride yog cov tshuaj sib xyaw ua ke ntawm txhuas thiab chlorine, nrog cov mis AlnCl (3n-m) (OH) m.Nws muaj ntau yam xwm txheej tshwm sim los ntawm qhov tseeb tias nws tuaj yeem muaj nyob hauv ntau hom nyob ntawm qhov sib piv ntawm txhuas-rau-chloride thiab qib ntawm polymerization.Cov kev hloov pauv no tso cai rau PAC hloov mus rau ntau yam kev sib tw hauv dej.

Coagulation thiab Flocculation:

Lub luag haujlwm tseem ceeb ntawm PAC hauv kev kho dej yog coagulation thiab flocculation.Thaum PAC ntxiv rau cov dej nyoos, nws nkag mus rau hydrolysis.Thaum lub sijhawm txheej txheem no, nws tsim aluminium hydroxide flocs, uas muaj txiaj ntsig zoo ntawm kev ntes cov impurities tshem tawm hauv dej.Cov txhuas hydroxide flocs ua zoo li cov hlau nplaum me me, nyiam thiab khi ua ke cov khoom xws li av, kab mob, thiab cov organic teeb meem.

Tshem tawm ntawm impurities:

PAC's coagulation-flocculation mechanism pab tshem tawm ntau yam impurities ntawm dej, suav nrog cov khib nyiab tshem tawm, colloids, thiab txawm tias qee cov tshuaj yaj.Raws li cov flocs loj tuaj thiab hnyav dua, lawv nyob rau hauv qab ntawm lub tank kho los ntawm sedimentation los yog yooj yim cuab los ntawm lim.Qhov no ua rau kev tsim cov dej ntshiab thiab huv.

pH Neutrality:

Ib qho txiaj ntsig tseem ceeb ntawm PAC yog nws cov pH nruab nrab.Tsis zoo li cov tshuaj coagulants ib txwm muaj xws li txhuas sulfate lossis ferric chloride, uas tuaj yeem hloov pauv pH ntawm dej, PAC tswj cov qib pH kuj ruaj khov.Qhov no txo ​​qis qhov xav tau ntawm cov tshuaj ntxiv los kho cov pH, ua kom yooj yim rau kev kho thiab txo cov nqi.

Cov txiaj ntsig ntawm Kev Siv PAC:

Kev ua tau zoo: PAC ua haujlwm tau zoo thoob plaws qhov dav ntawm cov dej zoo thiab turbidities.

Versatility: Nws tuaj yeem siv tau rau ob qho tib si thawj thiab qib siab kho dej.

Cov seem qis: PAC tsim cov sludge tsawg dua los ntawm cov khoom lag luam, txo cov nqi pov tseg.

Tus nqi-zoo: Nws qhov ua tau zoo thiab pH nruab nrab ua rau nws xaiv tus nqi zoo rau cov nroj tsuag kho dej.

Kev Nyab Xeeb: PAC feem ntau suav hais tias muaj kev nyab xeeb dua los tuav dua li lwm cov coagulants.

Kev siv PAC:

PAC pom ntau daim ntawv thov hauv ntau qhov kev lag luam, suav nrog kev kho dej hauv nroog, kev kho dej khib nyiab, thiab txawm tias nyob rau hauv daim ntawv thiab textile kev lag luam.Nws lub peev xwm los tshem tawm ntau yam kab mob ua rau nws yog ib qho cuab yeej tseem ceeb rau kev ua kom cov khoom siv dej huv thiab nyab xeeb.

Hauv kev xaus, Poly Aluminium Chloride (PAC) yog cov tshuaj kho dej zoo kawg nkaus uas ua haujlwm los ntawm coagulation thiab flocculation.Nws txoj kev ua tau zoo, ntau yam, thiab pH nruab nrab tau tso nws qhov kev xaiv zoo tshaj plaws rau cov chaw kho dej thoob ntiaj teb.Raws li qhov kev thov rau cov dej huv txuas ntxiv mus ntxiv, PAC tseem yog tus tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab siv tau dej rau cov zej zog thoob plaws ntiaj teb.
