Polyacrylamide flocculants muaj txiaj ntsig zoo hauv sludge dewatering thiab dej phwj tuaj.Qee cov neeg siv khoom tshaj tawm tias polyacrylamide pam siv hauv sludge dewatering yuav ntsib xws li thiab lwm yam teeb meem.Hnub no, kuv yuav txheeb xyuas ntau yam teeb meem rau sawv daws.:
1. Cov nyhuv flocculation ntawm polyacrylamide tsis zoo, thiab yog vim li cas nws thiaj li tsis tuaj yeem nias rau hauv sludge?Yog tias cov nyhuv flocculation tsis zoo, peb yuav tsum ua ntej tshem tawm cov teeb meem zoo ntawm cov khoom flocculant nws tus kheej, seb cov cationic polyacrylamide ua tau raws li tus qauv ionic molecular hnyav, thiab cov sludge dewatering nyhuv ntawm cov khoom uas tsis ua raws li tus qauv nws yeej tsis zoo. .Hauv qhov no, hloov PAM nrog rau qib ion haum tuaj yeem daws qhov teeb meem.
2. Kuv yuav ua li cas yog tias tus nqi ntawm polyacrylamide loj dhau lawm?
Ib tug loj npaum li cas txhais tau hais tias cov ntsiab lus Performance index ntawm cov khoom tsis txaus, thiab muaj qhov sib txawv ntawm cov indexes xav tau rau polyacrylamide thiab sludge flocculation.Lub sijhawm no, koj yuav tsum xaiv hom dua, xaiv tus qauv tsim nyog PAM thiab ntxiv cov nyiaj ntxiv rau kev sim, thiab tau txais kev siv nyiaj txiag ntau dua.nqi.Feem ntau, nws raug pom zoo tias qhov concentration ntawm polyacrylamide yog ib txhiab mus rau ob txhiab, thiab ib qho kev sim me me tau ua raws li qhov kev xav tau no, thiab cov txiaj ntsig tau txais yog qhov tsim nyog.
3.Kuv yuav ua li cas yog tias viscosity ntawm sludge tom qab siv polyacrylamide hauv sludge dewatering siab?
Qhov teeb meem no yog vim qhov sib ntxiv ntawm polyacrylamide ntau dhau los yog cov khoom siv tsis raug thiab cov sludge.Yog tias cov viscosity ntawm cov sludge txo qis tom qab txo qhov sib ntxiv, ces nws yog ib qho teeb meem ntawm qhov sib ntxiv.Yog tias qhov sib ntxiv yog txo, cov nyhuv tsis tiav thiab cov sludge tsis tuaj yeem nias, ces nws yog ib qho teeb meem ntawm kev xaiv cov khoom.
4. Polyacrylamide yog ntxiv rau cov sludge, thiab cov dej ntsiab lus ntawm cov ncuav qab zib tom qab av nkos siab dhau lawm, kuv yuav ua li cas yog tias cov ncuav mog qab zib tsis qhuav txaus?
Hauv qhov no, thawj zaug xyuas cov khoom siv lub cev qhuav dej.Lub tshuab siv yuav tsum xyuas seb qhov stretch ntawm daim ntaub lim tsis txaus, cov ntaub lim dej permeability thiab seb cov ntaub lim dej puas yuav tsum tau hloov;lub phaj thiab thav duab lim xovxwm yuav tsum tau xyuas seb lub sij hawm lim lim puas txaus, Seb lub siab ntawm lub lim yog tsim nyog;lub centrifuge yuav tsum tau xyuas seb qhov kev xaiv ntawm lub dehydrating agent puas tsim nyog.Stacked ntsia hlau thiab decanter lub cev qhuav dej cov cuab yeej tsom mus rau kev tshuaj xyuas seb qhov hnyav molecular ntawm polyacrylamide siab dhau lawm, thiab cov khoom uas muaj viscosity siab dhau yuav tsis haum rau nias av nkos!
Tseem muaj ntau yam teeb meem ntawm polyacrylamide hauv sludge dewatering.Cov saum toj no yog cov teeb meem ntau dua thiab cov kev daws teeb meem uas tau sau tseg hauv ntau qhov kev debugging ntawm qhov chaw.Yog tias koj muaj lus nug txog cationic polyacrylamide sludge pressing lossis sedimentation, txhua yam Koj tuaj yeem xa email rau peb, peb tham txog kev siv polyacrylamide hauv sludge dewatering!
