Cov kev coj ua zoo tshaj plaws rau kev sib xyaw ua ke ntawm PAC thiab PAM: Cov hau kev tseem ceeb los txhim kho kev kho dej coagulation cuam tshuam thiab kev kho dej khib nyiab

Nyob rau hauv niaj hnubkev kho dejcov txheej txheem, tso siab rau ib qho coagulant nkaus xwb feem ntau ua rau nws nyuaj rau ua kom tau raws li cov qauv dej nruj dua. Txawm hais tias hauv kev kho dej hauv nroog, kev kho dej khib nyiab, lossis kev kho dej khib nyiab hauv kev lag luam xws li mining, thee ntxuav, thiab ntawv tsim, kev txhim kho cov pa phem tshem tawm, txo cov tshuaj siv tshuaj, thiab txhim kho cov kev kho sludge tau dhau los ua cov ntsiab lus tseem ceeb hauv kev kho dej engineering.

Polyaluminium Chloride (PAC)thiabPolyacrylamide (PAM), raws li ob feem ntau siv tshuaj kho dej, ua haujlwm sib koom ua ke los ntawm cov txheej txheem sib txawv ntawm kev ua kom zoo dua coagulation thiab flocculation kev ua tau zoo. Tsim nyog daim ntawv thov ntawm PAC + PAM ua ke cov txheej txheem kev kho mob tuaj yeem tsim cov qauv floc loj dua, ua kom nrawm nrawm, txo qis cov dej ntws tawm, thiab ua kom zoo dua cov txheej txheem sludge dewatering.

ECOLINK TECHNOLOGY tsom mus rau cov tshuaj kho dej thiab kev tiv thaiv ib puag ncig, muab cov neeg siv khoom nrog cov khoom lag luam suav nrog kev lag luam -qib PAC, dej haus- qib PAC, anionic PAM, cationic PAM, thiab tsis yog - ionic PAM, nrog rau muab PAC thiab PAM sib tw daim ntawv thov kev pom zoo raws li cov dej zoo sib txawv.

I. Vim li cas Kev Sib Txuas PAC thiab PAM tau txais txiaj ntsig zoo dua?

Hauv cov txheej txheem kev kho dej, coagulation thiab flocculation yog ob ntu txuas ntxiv.

Ntawm lawv, Polyaluminium Chloride (PAC) yog lub luag haujlwm tseem ceeb rau theem coagulation. Los ntawm kev them nqi nruab nrab, nws destabilizes colloidal hais nyob rau hauv dej, ua kom cov pa phem me me los tsim micro-flocs.

Polyacrylamide (PAM) feem ntau ua nyob rau theem flocculation. Los ntawm cov adsorption bridging nyhuv ntawm polymer chains, nws txuas ntxiv rau micro-flocs uas twb tsim los tsim loj, denser, thiab yooj yim dua flocs.

Cias muab:

PAC yog lub luag haujlwm rau "ua kom puas tsuaj ruaj khov"

PAM yog lub luag haujlwm rau "txuas cov khoom kom tsim cov flocs loj"

Thaum ob qhov sib xyaw ua ke, kev kho mob zoo tuaj yeem ua tiav dua li kev siv tshuaj ib leeg.

Raws li cov ntaub ntawv siv tau, piv nrog kev siv PAC ib leeg, floc loj tsim tom qab siv ua ke ntawm PAC thiab PAM feem ntau tuaj yeem nce ntxiv los ntawm 3-10 zaug, thaum qhov kev daws teeb meem nrawm nrawm thiab sludge compaction kev ua tau zoo kuj tseem txhim kho.

II. Mechanism of Action of PAC nyob rau hauv cov txheej txheem coagulation

Polyaluminum Chloride (PAC) yog ib qho zoo heev inorganic polymer coagulant siv dav hauv kev lim dej, kev kho dej khib nyiab, thiab kev kho dej hauv nroog.

Cov khoom raug tshem tawm thiab cov khoom colloidal hauv dej feem ntau muaj cov nqi tsis zoo. Vim yog electrostatic repulsion ntawm cov khoom, lawv tuav ib tug ruaj khov dispersed lub xeev nyob rau hauv lub sij hawm ntev thiab nyuaj rau nyob rau hauv ib txwm muaj.

Tom qab PAC ntxiv rau hauv lub cev dej, cov aluminium polymers nyob rau hauv nws tuaj yeem cuam tshuam cov nqi tsis zoo ntawm cov khoom seem, ua rau cov colloids poob stability thiab maj mam tsim me me flocs.

Cov txheej txheem no feem ntau suav nrog:

1. Them nqi Neutralization

Cov txhuas ions hauv PAC hydrolyze los tsim multinuclear hydroxy- txhuas cov qauv, uas tuaj yeem txo cov electrostatic repulsion ntawm cov khoom thiab ua rau cov pa phem pib sib sau.

2. Micro-floc Tsim

Tom qab sib tov sai, ntau cov khoom zoo sib xyaw ua ke ua thawj micro-flocs.

Txawm li cas los xij, vim tias cov micro-flocs no me me, lawv qhov kev daws teeb meem ceev tsuas yog nyob ntawm lawv tus kheej qhov hnyav xwb; Yog li ntawd, ntxiv qhov ntxiv ntawm PAM feem ntau yog xav tau rau kev txhim kho flocculation.

III. Yuav Ua Li Cas PAM Txhim Kho Flocculation Effects ntawm PAC

Polyacrylamide (PAM) yog siab -molecular- hnyav polymer flocculant. Nyob ntawm tus nqi zog, nws feem ntau muab faib ua:

Anionic Polyacrylamide (APAM)

Cationic Polyacrylamide (CPAM)

Tsis yog -ionic Polyacrylamide (NPAM)

Ntau hom PAM muaj cov xwm txheej sib txawv.

Qhov loj tshaj plaws ntawm PAM yog nws cov qauv sib txuas ntev polymer, uas tuaj yeem nqus tau ntau yam micro-flocs ib txhij, txuas cov khoom me me mus rau hauv cov flocs loj los ntawm "bridging action".

Piv txwv li, qhov hnyav molecular ntawm PAM feem ntau tuaj yeem ncav cuag 10 lab txog 20 lab Daltons. Cov saw hlau polymer tuaj yeem nthuav dav ntawm ntau qhov sib txuas los tsim kev sib txuas thiab ua kom muaj zog floc.

PAC tsim "me me thiab ntom micro-flocs", thaum PAM txuas ntxiv cov micro-flocs rau hauv "loj flocs".

Cov teebmeem kawg suav nrog:

Nce floc loj

Accelerated daws ceev

Txo effluent turbidity

Txhim kho sludge dewatering kev ua tau zoo

Yog li ntawd, nyob rau hauv ntau txoj haujlwm kho dej khib nyiab, kev sib xyaw ua ke ntawm PAC coagulant thiab PAM flocculant tau dhau los ua cov tshuaj tseem ceeb los txhim kho kev kho mob.

IV. Dab tsi yog qhov zoo ntawm PAC + PAM kev kho mob sib xyaw piv rau kev siv PAC Ib leeg?

Peb tuaj yeem muab:

✔ PAC / PAM cov lus pom zoo raws li cov dej nyoos

✔ Technical parameter piv cov lus pom zoo

✔ Kev them nyiaj yug rau kev xeem

✔ Cov lus qhia kev xeem lub thawv

✔ COA, SDS, kev txhawb nqa cov ntaub ntawv

✔ Cov kev pabcuam xa tawm raws li kev lag luam txawv teb chaws

Seb koj qhov project belongs rau:

Kev kho dej phwj hauv nroog

Kev kho dej khib nyiab

Kev kho dej khib nyiab tsuas

Coal ntxuav dej kho

Sludge dewatering

ECOLINK TECHNOLOGY tuaj yeem pab koj nrhiav kev kho mob zoo dua thiab siv tau zoo.

XVIII. Xaus: Ua kom raug PAC thiab PAM kom tau txais txiaj ntsig kev kho dej ntau dua

Kev siv ua ke ntawm PAC thiab PAM tsis yog tsuas yog ntxiv ob yam tshuaj ib txhij, tab sis ib txoj kev kho mob uas yuav tsum tau xav txog:

Hom tshuaj

Dosing sequence

Kev faib ua feem

Cov dej tsis zoo

Kev ua haujlwm tsis ua haujlwm

Kev khiav dej num raug:

PAC nqi neutralization → Micro- floc tsim → PAM bridging flocculation → Loj floc teeb

Piv nrog rau kev siv PAC ib leeg, qhov tsim nyog PAC + PAM ua ke txheej txheem tuaj yeem:

Tsim cov flocs loj dua

Txhim kho qhov ceev ceev

Txo cov dej turbidity

Txhim kho sludge dewatering kev ua tau zoo

Optimize tag nrho cov nqi ua haujlwm

Yog tias koj tab tom nrhiav PAC thiab PAM flocculation tov haum rau cov dej khib nyiab hauv nroog, cov dej phwj tuaj hauv nroog, kev kho dej mining, lossis cov dej sludge dewatering, ECOLINK TECHNOLOGY tuaj yeem muab cov lus qhia ua haujlwm raws li koj cov dej zoo.

Txais tos tiv tauj peb kom tau txais:
