Kev siv ntawm Polyacrylamide (PAM) hauv Kev Kho Dej Haus

Hauv thaj chaw ntawm kev kho dej, kev nrhiav kom huv thiab nyab xeeb haus dej yog qhov tseem ceeb. Ntawm ntau cov cuab yeej muaj rau txoj haujlwm no,polyacrylamide(PAM), tseem hu ua coagulant, sawv tawm los ua ntau yam thiab siv tau zoo. Nws daim ntawv thov nyob rau hauv cov txheej txheem kho kom zoo tshem tawm cov impurities thiab cov kab mob, yog li txhim kho cov dej haus zoo. Kab lus no delves rau hauv ntau daim ntawv thov ntawm polyacrylamide hauv kev kho dej haus, qhia nws lub luag haujlwm ua ib qho tseem ceeb hauv cov txheej txheem purification.

1. Coagulationthiab Flocculation

Ib qho ntawm cov kev siv tseem ceeb ntawm polyacrylamide hauv kev kho dej haus yog nyob rau hauv cov txheej txheem ntawm coagulation thiab flocculation. Coagulation cuam tshuam nrog kev ua kom tsis muaj zog ntawm colloidal hais los ntawm kev sib ntxiv ntawm cov tshuaj, ua kom lawv cov kev sib sau ua ke. polyacrylamide pab nyob rau hauv cov txheej txheem no los ntawm neutralizing tus nqi tsis zoo ntawm tshem tawm hais, txhawb lawv aggregation mus rau hauv loj, settleable flocs. Tom qab ntawd, flocculation ua kom muaj qhov loj thiab denser flocs, uas tuaj yeem tshem tau yooj yim los ntawm cov txheej txheem sedimentation lossis pom.

2. Txhim kho kev tshem tawm cov kab mob

polyacrylamide txhim khu kev tshem tawm ntawm ntau yam kab mob uas muaj nyob hauv cov dej haus. Los ntawm kev ua kom yooj yim tsim cov flocs loj, nws txhim kho cov txheej txheem sedimentation thiab pom, ua rau kev tshem tawm cov khib nyiab pov tseg, organic teeb meem, thiab kab mob. Tsis tas li ntawd, PAM pab tshem tawm cov hlau hnyav, xws li cov hlau lead thiab arsenic, los ntawm kev tsim cov complexes nrog cov ions, yog li tiv thaiv lawv rov tawg mus rau hauv cov dej kho.

3. Turbidity txo

Turbidity, tshwm sim los ntawm cov khoom raug tshem tawm hauv dej, tsis yog tsuas yog cuam tshuam rau kev zoo nkauj ntawm cov dej haus, tab sis kuj yog ib qho kev qhia txog dej zoo. polyacrylamide ua tau zoo txo ​​cov turbidity los ntawm kev txhawb cov aggregation ntawm nplua hais mus rau hauv loj flocs, uas nyob twj ywm sai dua. Qhov no ua rau kom pom tseeb thiab pom kev haus dej haus, ua tau raws li cov qauv kev cai thiab cov neeg siv khoom xav tau.

Hauv kev xaus, polyacrylamide (PAM) plays lub luag haujlwm tseem ceeb hauv kev kho cov dej haus, muab ntau yam txiaj ntsig ntawmCoagulation, tshem tawm cov kab mob, txo turbidity, tshem tawm algae, thiab hloov pH. Nws muaj ntau yam xwm txheej thiab kev ua tau zoo ua rau nws muaj txiaj ntsig zoo rau cov nroj tsuag kho dej siv zog los muab cov dej huv huv, nyab xeeb, thiab ua kom zoo nkauj rau cov neeg siv khoom. Raws li kev nce qib hauv kev kho dej thev naus laus zis txuas ntxiv mus, polyacrylamide tau npaj los ua lub hauv paus tseem ceeb hauv kev nrhiav kev tswj dej kom ruaj khov thiab kev tiv thaiv pej xeem kev noj qab haus huv.
