Los ntawm hom nqi them, txo cov qauv ntawm cov nplaim plab, qhov kev xaiv ntawm cov dej phwj tuaj, thiab kev xaiv ntawm cov dej phwj tuaj yeem nkag siab yooj yim. ,
1. Hom kev them nqi ntawm Flocculant
Kev siv hluav taws xob ntawm cov flocculant yog xaiv raws li hom ntawm cov khoom hauv cov dej phwj tuaj hauv cov dej phwj tuaj. Feem ntau, tus nqi hluav taws xob ntawm cov flocculusts yuav tsum ua raws li cov hauv qab no
Hauv txoj ntsiab cai;
Siv tsis zoo them flocculants mus ntes inorganic hais
Zoo them tus flocculant mus ntes organic hais
Feem ntau, hom flocculant them tuaj yeem txiav txim siab raug los ntawm kev sim kev sim.
2. Flocculation Them Kev faib tawm ntom (ion)
Qhov ceev ntawm tus nqi them rau cov flocculant qhia tau tus nqi zoo lossis tsis zoo los ntawm Flocculant tau txais qhov tsawg kawg ntawm FLOCCULANT siv. Kev faib tawm cov nqi hluav taws xob muaj feem xyuam rau hom sludge. Tus nqi xa tawm ntom ntom ntawm cov chaw nkaum hluav taws xob feem ntau yog ua haujlwm ntawm cov ntsiab lus organic hauv sludge. Cov ntsiab lus organic yog feem ntau cuam tshuam nrog cov ntsiab lus volatile. Cov ntsiab lus ntau dua cov ntsiab lus tsis meej, cov nqi siab dua. Flocculant.
3. Molecular hnyav
Qhov kev xaiv ntawm cov roj molecular yog nyob ntawm cov khoom siv uas tau siv nyob rau hauv kev kho mob lub cev qhuav dej, thaum lub cev molecular kuj tseem sawv cev rau qhov ntev ntawm cov ntaub pua npab ntawm polymer. Rau centrifuge-hom dewatering khoom siv: qhov loj dua ntawm cov polymer, qhov zoo dua, vim tias hauv cov txheej txheem centrifugal, tus floc yuav raug rau lub zog loj. Rau Lim-Hom Dewatering Cov Khoom Siv: Qhov hnyav nrog lub cev muaj zog me me mus ua tau raws li qhov yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua kom tau.
4. Molecular qauv qauv
Qhov kev xaiv ntawm cov qauv molecular ntawm cov flocculant nyob ntawm qhov xav tau kev ua haujlwm ntsw. Cov qauv molecular ntawm cationic flocculant tau muab faib ua: kab qauv qauv, qauv qauv, hla kev sib txuas network qauv
Los ntawm cov kev sib tham saum toj no, peb tuaj yeem pom yooj yim uas qhov kev xaiv ntawm Flocculant yog ib txwm muaj. Tsuav peb ua tib zoo saib nws txoj cai, peb yuav qhia tau nws hauv daim ntawv thov txhua hnub thiab pom tias txhua hom dej khib nyiab muaj nws ib qho. Ib lossis ntau tus flocculants tuaj yeem txaus siab rau cov flocculation lossis lub cev qhuav dej ntawm cov dej phwj tuaj.
