PAM Flocculant: cov khoom siv tshuaj lom neeg muaj zog rau kev kho dej hauv kev lag luam

Polyacrylamide(PAM) yog ib hom polymer uas siv rau hauv cov dej kho dej uas siv dav hauv cov txheej txheem kho dej. Nws feem ntau yog siv ua flocculant thiab coagulant, ib yam tshuaj uas ua rau cov khoom me me hauv dej sib sau ua ke ua cov flocs loj dua, yog li pab tshem tawm lawv los ntawm kev ua kom huv lossis lim dej. Nyob ntawm qhov zoo ntawm cov dej khib nyiab, siv cationic, anionic, lossis non-ionic PAM. Polyacrylamide muaj ntau yam zoo hauv kev kho dej, suav nrog nws cov txiaj ntsig zoo dua ntau yam pH, kub, thiab turbidity. Cov nyhuv coagulation tuaj yeem sim siv Jar tests lossis turbidity ntsuas.

Polyacrylamide siv tau dav hauv kev kho dej hauv kev lag luam, kev kho dej phwj tuaj, kev kho dej khib nyiab, thiab lwm yam. Hauv cov chaw kho dej, polyacrylamide siv rau ntau yam txheej txheem, suav nrog kev ua kom pom tseeb thawj zaug thiab thib ob, kev lim dej, thiab kev tua kab mob. Thaum lub sijhawm ua kom pom tseeb thawj zaug, nws raug ntxiv rau hauv dej nyoos los txhawb kev sib sau ua ke ntawm cov khoom khov kho, uas tom qab ntawd raug tshem tawm los ntawm kev tso dej lossis kev ntab. Hauv kev ua kom pom tseeb thib ob, polyacrylamide yog siv los ua kom pom tseeb ntxiv rau cov dej kho los ntawm kev tshem tawm cov khoom khov kho seem thiab cov organic uas nqus tau.

Lub hauv paus ntsiab lus ua haujlwm ntawmpolyacrylamide flocculantyog: tom qab ntxiv cov tshuaj PAM, PAM nqus cov khoom me me, tsim cov choj ntawm lawv. Hauv lub pas dej qub, nws lo rau cov flocs loj dua, thiab lub cev dej ua turbid thaum lub sijhawm no. Tom qab ntau cov flocs loj hlob thiab ua tuab dua, lawv yuav tsiv teb tsaws chaw thiab poob qis qeeb dhau sijhawm, thiab txheej sab saud ntawm cov dej nyoos yuav dhau los ua kom pom tseeb. Cov txheej txheem sib sau ua ke no txhim kho cov yam ntxwv ntawm cov khoom me me, ua rau lawv yooj yim tshem tawm thaum lub sijhawm ua kom pom tseeb lossis lim dej. Polyacrylamide feem ntau siv ua ke nrog lwm cov coagulants thiab flocculants kom ua tiav qhov ua kom pom tseeb thiab kev lim dej zoo tshaj plaws.

Polyacrylamide kuj tseem ua lub luag haujlwm tseem ceeb hauv kev lim dej. Nws feem ntau siv ua lub lim ua ntej hauv cov lim dej lossis lwm txoj kev lim dej kom tshem tawm cov khoom khov thiab cov dej turbidity. Los ntawm kev txhim kho kev tshem tawm cov khoom me me no, polyacrylamide pab ua kom cov dej lim huv dua thiab huv dua.

Polyacrylamide yog ib qho polymer ruaj khov thiab tsis muaj tshuaj lom uas tawg los ntawm cov txheej txheem ntuj lossis cov txheej txheem kho mob. Yuav tsum nco ntsoov tias cov tshuaj nchuav yuav ua rau hauv pem teb nplua heev, uas yuav ua rau koj poob.

Txawm li cas los xij, qhov ntau ntawm PAM siv nyob ntawm hom dej khib nyiab thiab cov ntsiab lus ntawm cov khoom khov kho, nrog rau qhov muaj lwm yam tshuaj lom neeg, cov kua qaub, thiab cov pa phem hauv dej. Cov yam no yuav cuam tshuam rau cov nyhuv coagulation ntawm PAM, yog li yuav tsum tau hloov kho kom tsim nyog thaum siv. Cov khoom PAM nrog cov qhov hnyav molecular sib txawv, cov degree ionic, thiab cov koob tshuaj yuav tsum tau xaiv kom zoo rau ntau hom dej khib nyiab.
