Sludge nias ntawm Belt Lim Xovxwm yog txheej txheem ua haujlwm dynamic.Muaj ob peb yam uas cuam tshuam rau tus nqi thiab ceev ntawm sludge.
1. Sludge noo noo cov ntsiab lus ntawm thickener
Cov dej noo ntawm cov sludge hauv cov thickener yog qis dua 98.5%, thiab cov sludge tawm ceev ntawm cov sludge xovxwm yog ntau dua 98.5.Yog tias cov dej noo ntawm cov sludge qis dua 95%, cov sludge yuav poob nws cov fluidity, uas tsis tsim nyog rau sludge nias.Yog li ntawd, nws yog ib qho tsim nyog los txo cov dej ntawm cov sludge hauv cov thickener, tab sis cov ntsiab lus dej yuav tsum tsis pub tsawg dua 95%.
2. Tus nqi ntawm cov activated sludge hauv sludge
Cov sludge ua kom muaj zog ntau dua li cov tom qab anaerobic nitrification, thiab cov dej dawb sib cais zoo dua los ntawm cov sludge tom qab sib xyaw nrog PAM.Los ntawm kev ua haujlwm sludge nias, nws pom tau tias thaum qhov kev faib ua feem ntawm anaerobic nitrified sludge nyob rau hauv lub thickener yog siab, cov khoom-kua sib cais nyhuv tsis zoo tom qab sib tov sludge thiab tshuaj.Cov sludge me me dhau lawm yuav ua rau qis permeability ntawm cov ntaub lim dej hauv cov ntsiab lus concentration, ua rau lub nra ntawm cov kua-kua sib cais hauv ntu siab, thiab txo cov zis ntawm cov sludge xovxwm.Thaum qhov kev faib ua feem ntawm activated sludge nyob rau hauv lub thickener yog siab, cov khoom-kua sib cais nyhuv nyob rau hauv lub thickening seem ntawm sludge xovxwm yog zoo, uas yuav txo tau lub nra ntawm solid-kua sib cais ntawm lub lim ntaub nyob rau hauv lub siab filtration seem.Yog hais tias muaj ntau cov dej dawb ntws tawm ntawm qhov concentration, qhov ntws ntawm cov tshuaj sludge sib xyaw ntawm lub tshuab sab saud tuaj yeem tsim nyog, txhawm rau ua kom cov sludge tso tawm ntawm sludge xovxwm hauv chav tsev lub sijhawm.
3. Cov tshuaj av nkos piv
Tom qab ntxiv PAM, cov sludge yog thawj zaug sib xyaw los ntawm cov kav dej sib tov, sib xyaw ntxiv rau hauv cov kav dej txuas ntxiv, thiab thaum kawg sib xyaw los ntawm lub tank coagulation.Hauv kev sib tov, tus neeg sawv cev sludge cais feem ntau ntawm cov dej dawb los ntawm cov sludge los ntawm cov nyhuv turbulent hauv cov ntws, thiab tom qab ntawd ua tiav cov txiaj ntsig ntawm cov khoom ua ntej-kua sib cais hauv seem concentration.Dawb PAM yuav tsum tsis txhob muaj nyob rau hauv qhov kawg av nkos tshuaj tov tov.
Yog tias qhov ntau npaum li cas ntawm PAM loj dhau thiab PAM tau nqa hauv cov tshuaj sib xyaw, ntawm ib sab, PAM yog nkim, ntawm qhov tod tes, PAM sticks rau cov ntaub lim dej, uas tsis tsim nyog rau kev ntxuav cov ntaub lim dej los ntawm txau dej, thiab thaum kawg ua rau lub qhov thaiv ntawm cov ntaub lim dej.Yog tias qhov ntau npaum ntawm PAM tsawg dhau, cov dej dawb hauv cov av nkos tshuaj tov tsis tuaj yeem sib cais los ntawm cov sludge, thiab cov sludge hais thaiv cov ntaub lim, yog li cov khoom sib cais tsis tuaj yeem nqa tawm.
