Polyacrylamide rau Kev Kho Mob Tso Tseg

Polyacrylamide (PAM), Alias: Flocculant, anion, cation,

polymer; Polymers, tuav cia thiab siv dag pab, tuav tsis tau pab, dispersants; Polymer, roj kev hloov pauv, thiab lwm yam.

Yam cuam tshuam rau cov nyhuv ntawm cov dej phwj tuaj:

1. Sludge yog cov khoom lag luam uas tsis muaj dej phwj tuaj. Ua ntej tshaj plaws, peb yuav tsum nkag siab txog qhov, xwm, muaj pes tsawg leeg thiab cov ntsiab lus ntawm sludge. Raws li lub ntsiab muaj pes tsawg leeg ntawm sludge, sludge tuaj yeem faib ua cov organic sludge thiab inorganic sludge. Feem ntau hais lus, cationic polyacrylamide yog siv rau kev kho mob organic sludge, anionic polyacrylamide yog siv rau kev kho mob ntawm inorganic sludge. Nws tsis yooj yim siv cationic polyacrylamide thaum lub alkaline yog muaj zog heev, thiab nws tsis haum rau siv anionic polyacrylamide thaum cov ntsiab lus ntawm sludge yog siab.

3. Qhov luaj li ntawm cov flocs: flocs me me yuav cuam tshuam rau kev nrawm nrawm, Flocs dhau los ua ke rau cov dej ntws ntau dua thiab txo cov av nkos basit degree. Qhov loj ntawm flocs tuaj yeem hloov kho los ntawm kev xaiv molecular qhov hnyav ntawm polyacrylamide.

4. Lub zog ntawm Flocs: Flocs yuav tsum nyob ruaj khov thiab tsis tawg nyob rau hauv qhov kev txiav txim ntawm shear. Ua kom muaj zog hnyav ntawm polyacrylamide lossis xaiv cov qauv molecular tsim nyog yuav pab tau ruaj khov ntawm flocs.

5. Qhov sib tov ntawm polyacrylamide thiab sludge: polyacrylamide nyob rau hauv ib txoj hauj lwm ntawm cov khoom siv lub cev qhuav dej yuav tsum muaj qhov ua kom zoo nkauj nrog sludge, flocculation. Yog li ntawd, viscosity ntawm polyacrylamide kua yuav tsum yog qhov tsim nyog, thiab nws tuaj yeem sib xyaw nrog sludge hauv qab cov cuab yeej muaj kev muaj peev xwm. Seb ob lub ob yog sib xyaw tusyees yog qhov tseem ceeb rau kev ua tiav. Lub viscosity ntawm cationic polyacrylamide daws muaj feem xyuam rau nws cov molecular hnyav thiab kev npaj kev txhawb.

6. Kev tshem tawm ntawm cationic polyacrylamide: yaj zoo muab tag nrho ua si rau flocculation. Qee lub sij hawm nws yog qhov tsim nyog los ua kom nrawm dua qhov kev cais tawm, thaum lub concentration ntawm polyacrylamide daws teeb meem tuaj yeem suav tau.
