Cov tshuaj flocculants Polyacrylamide zoo heev rau kev tshem cov sludge thiab cov dej phwj tuaj. Qee tus neeg siv khoom tshaj tawm tias cov polyacrylamide pam siv rau hauv kev tshem cov sludge yuav ntsib teeb meem zoo li no thiab lwm yam. Hnub no, kuv yuav tshuaj xyuas ntau yam teeb meem uas txhua tus neeg ntsib.
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 tshem tawm cov teeb meem zoo ntawm cov khoom flocculant nws tus kheej, seb cov cationic polyacrylamide puas ua tau raws li tus qauv ionic molecular weight, thiab cov nyhuv sludge dewatering ntawm cov khoom uas tsis ua tau raws li tus qauv Nws yeej tsis zoo. Hauv qhov no, hloov PAM nrog qib ion tsim nyog tuaj yeem daws qhov teeb meem.
2. Kuv yuav tsum ua li cas yog tias cov polyacrylamide ntau dhau?
Qhov ntau ntau txhais tau tias cov ntsiab lus ntawm cov khoom tsis txaus, thiab muaj qhov sib txawv ntawm cov ntsiab lus xav tau rau polyacrylamide thiab sludge flocculation. Lub sijhawm no, koj yuav tsum xaiv hom dua, xaiv tus qauv PAM tsim nyog thiab qhov ntxiv kom kuaj, thiab tau txais kev siv pheej yig dua. tus nqi. Feem ntau, nws raug pom zoo tias qhov concentration ntawm polyacrylamide yaj yog ib-txhiab txog ob-txhiab, thiab kev xaiv me me yog ua raws li qhov concentration no, thiab cov txiaj ntsig tau txais yog qhov tsim nyog dua.
3. Kuv yuav tsum ua li cas yog tias qhov viscosity ntawm sludge tom qab siv polyacrylamide hauv sludge dewatering siab?
Qhov xwm txheej no yog vim muaj ntau dhau ntawm polyacrylamide lossis cov khoom tsis raug thiab sludge. Yog tias qhov viscosity ntawm sludge txo qis tom qab txo qhov ntxiv, ces nws yog teeb meem ntawm qhov ntxiv. Yog tias qhov ntxiv raug txo qis, qhov cuam tshuam tsis tau tiav thiab sludge tsis tuaj yeem nias, ces nws yog teeb meem ntawm kev xaiv khoom.
4. Polyacrylamide raug ntxiv rau hauv cov sludge, thiab cov dej ntawm cov av nkos tom qab ntawd siab dhau, kuv yuav tsum ua li cas yog tias cov av nkos tsis qhuav txaus?
Hauv qhov no, ua ntej xyuas cov khoom siv dehydration. Lub tshuab siv yuav tsum xyuas seb qhov ncab ntawm daim ntaub lim puas tsis txaus, qhov dej permeability ntawm daim ntaub lim thiab seb daim ntaub lim puas yuav tsum tau hloov; lub phaj thiab thav duab lim xovxwm yuav tsum xyuas seb lub sijhawm lim puas txaus, seb qhov siab ntawm lub lim puas tsim nyog; lub centrifuge yuav tsum xyuas seb qhov kev xaiv ntawm tus neeg sawv cev dehydrating puas tsim nyog. Cov ntsia hlau thiab decanter dehydration khoom siv tsom mus rau kev xyuas seb qhov hnyav molecular ntawm polyacrylamide siab dhau, thiab cov khoom uas muaj viscosity siab dhau tsis zoo rau kev nias av nkos!
Tseem muaj ntau yam teeb meem ntawm polyacrylamide hauv sludge dewatering. Cov saum toj no yog cov teeb meem thiab cov kev daws teeb meem uas tau muab sau ua ke 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, cia peb tham txog kev siv polyacrylamide hauv sludge dewatering!
