Polyacrylamide- Lub Luag Haujlwm ntawm Cov Dej Phwj Dej Flocculants

Txhawm rau tawm lossis rov qab siv cov kav dej tom qab kev kho mob, muaj ntau yam tshuaj yuav tsum tau siv hauv cov txheej txheem dej phwj. Hnub no,Pam (polyacrylamide) cov neeg muab khoomyuav qhia koj txog flocculants:

Flocculant: Qee zaum kuj hu ua coagulant, nws tuaj yeem siv los ua ib txoj kev los txhawb nqa tank, thiab nws tuaj yeem siv tau hauv lub tsheb tsim kua, thiab kev kho mob ntawm huab tais lossis kev kho mob ntawm cov txheej txheem.

Flocculants siv los ua kev txhais tau tias ntawm kev ntxiv dag zog ua kua-kua sib cais hauv kev kho dej phwj. Lawv tuaj yeem siv los ntxiv dag zog rau qhov kev kho dej ntawm cov dej phwj tuaj thiab cov txheej txheem sludge, thiab tseem siv tau rau kev kho mob ntawm cov dej phwj. Thaum siv rau cov kev mob ua ntej lub cev qhuav dej ntawm cov sludge ntau dhau, flocculants thiab coagulants dhau los ua slude los yog cov neeg sawv cev qhuav dej.

Thaum siv cov tsoos flocculants, tus txheej txheem ntawm kev ntxiv cov pab cuam tshuam rau kev sib xyaw tuaj yeem siv los txhim kho cov txiaj ntsig flocculation. Piv txwv li, siv ua si cov silicic acid zoo li kev pab cuam kem tsis sib xws thiab txhuas surrous Yog li ntawd, nyob rau hauv Layman cov lus, Inorganic polymer Flocculant IPF yog tau npaj los ntawm kev sib xyaw ua ke kom yooj yim rau cov neeg siv lub lag luam.

Coagulation treatment is usually placed in front of the solid-liquid separation facility, and combined with the separation facility, it can effectively remove suspended solids and colloidal substances with a particle size of 1nm to 100μm in the raw water, reduce effluent turbidity and CODCr, thiab tuaj yeem siv tau hauv pretricalment ntawm cov txheej txheem dej phwj. Kev kho mob, kev kho siab heev, tuaj yeem siv rau kev kho kom zoo slude. Kev kho mob sib xyaw ua tau zoo tshem tawm cov kab mob me thiab roj pathogenic hauv dej, thiab lwm yam kuab tshuaj hauv cov dej phwj tuaj. Qhov kev tshem tawm ntawm phosphorus muaj nyob hauv cov dej phwj tuaj yeem yog li 90% thaum coagulation sedimentation yog siv los kho phosphorus. ~ 95%, yog cov qauv pheej yig tshaj plaws thiab ua tau zoo tshaj plaws ntawm phosphorus tshem tawm.

Nyob rau hauv cov txheej txheem ntawm kev kho dej phwj, lwm tus neeg sawv cev yuav raug siv. Niaj hnub no, tusPa vaj tseqhia tsuas yog ib qho ntawm lawv. Koj puas tseem nkag siab? Ua tib zoo saib Yuncang thiab teb cov kev paub txog kev lim dej ntau dua rau koj!
