Txhawm rau tso tawm lossis rov siv cov Dej Dej Tom Qab Kev Kho Mob, ntau yam tshuaj yuav tsum tau siv rau hauv cov txheej txheem dej phwj tuaj.Hnub no,PAM (Polyacrylamide) lwm tus neegYuav qhia rau koj txog flocculants:
Flocculant: Qee zaum kuj hu ua coagulant, nws tuaj yeem siv los ua ib txoj hauv kev los ntxiv dag zog rau cov kua dej sib cais, thiab nws tuaj yeem siv rau hauv qhov chaw tso dej hauv lub tank, theem nrab hauv lub tank, flotation tank, kev kho mob tertiary lossis kev kho mob siab thiab lwm yam kev sib txuas.
Flocculants yog siv los ua ib txoj hauv kev ntxiv dag zog rau cov kua-kua sib cais hauv kev kho dej phwj tuaj.Lawv tuaj yeem siv los ntxiv dag zog rau thawj qhov dej ntws ntawm cov dej phwj tuaj, kev kho flotation thiab theem nrab sedimentation tom qab qhib cov txheej txheem sludge, thiab tseem tuaj yeem siv rau kev kho tertiary lossis kev kho dej phwj siab.Thaum siv los ua kom txias ua ntej lub cev qhuav dej ntawm cov sludge ntau dhau, flocculants thiab coagulants ua sludge conditioners lossis dehydrating agents.
Thaum siv cov tshuaj flocculants, txoj kev ntxiv cov coagulant pab yuav siv tau los txhim kho cov nyhuv flocculation.Piv txwv li, siv activated silicic acid raws li ib tug coagulant pab rau inorganic flocculants xws li ferrous sulfate thiab txhuas sulfate thiab ntxiv rau lawv nyob rau hauv ib ntus yuav ua tau zoo flocculation.Yog li ntawd, nyob rau hauv layman cov ntsiab lus, cov inorganic polymer flocculant IPF yog tiag tiag npaj los ntawm combining cov coagulant pab thiab cov flocculant thiab ces ntxiv ua ke kom yooj yim rau cov neeg siv lub lag luam.
Coagulation kev kho mob feem ntau yog muab tso rau pem hauv ntej ntawm cov khoom-kua sib cais qhov chaw, thiab ua ke nrog cov chaw sib cais, nws muaj peev xwm tshem tawm cov khib nyiab thiab cov colloidal particle loj ntawm 1nm mus rau 100μm nyob rau hauv cov dej nyoos, txo effluent turbidity thiab CODCr, thiab tuaj yeem siv rau hauv pretreatment ntawm cov txheej txheem dej phwj tuaj.Kev kho mob, kev kho mob siab heev, kuj tuaj yeem siv rau kev kho cov sludge residual.Kev kho coagulation tseem tuaj yeem tshem tawm cov kab mob thiab cov kab mob pathogenic hauv dej, thiab tshem tawm cov roj emulsified, chroma, hnyav hlau ions thiab lwm yam khoom paug hauv dej phwj tuaj.Kev tshem tawm cov phosphorus uas muaj nyob rau hauv cov dej phwj tuaj yeem siab li 90% thaum coagulation sedimentation yog siv los kho phosphorus.~ 95%, yog qhov pheej yig tshaj thiab zoo tshaj txoj kev tshem tawm phosphorus.
Hauv cov txheej txheem ntawm kev kho cov dej phwj tuaj, lwm cov neeg ua haujlwm yuav raug siv.Hnub no, lubPAM Chaw tsim tshuaj pausqhia tsuas yog ib qho ntawm lawv.Koj puas tseem nkag siab?Ua tib zoo mloog rau Yuncang thiab teb cov kev paub txog kev kho dej phwj ntxiv rau koj!
