Peb Cov Cim Ntawm Cov Txij Nkawm Sludge
Cov dej ntsiab lus yog siab. Cov dej ntsiab lus ntawm tus thawj sludge hauv ntawv zeb ntau tshaj 99%, thiab cov dej ntsiab lus ntawm sludge yog ntau dua 95% tom qab concentration, thiab nws muaj fluidity.
Cov ntsiab lus fiber ntau loj. Muaj ntau ntau cov fiber nyob rau hauv lub papermaking sludge. Muab piv nrog kiag sludge, cov ntsiab lus ntawm cov organic teeb meem tsawg tsawg thiab qhov tob ntawm sludge lub cev qhuav dej yog qhov nyuaj kom txo.
Daim ntawv zeb tsim tawm ntau heev ntawm av. Tus kab mob SS yog 2100 txog 4400mg / L thiab CODcr yog 1700 txog 4800mg / L; tus effluent SS yog 15 mus rau 40mg / L thiab CODcr yog 70 ~ 100mg / L ..
Kev muab cov txheej txheem pov tseg ntawm cov phaj papermaking
Papermaking sludge txias
Papermaking sludge concentration, hloov los ntawm kev ntxiv thiab reagent, hydrophilicity txo, yooj yim rau qhuav ua machinery. Yuav tsis muaj rau cov txiv qaub los ntxiv, thaum lub papermaking sludge yog quenched thiab tempered. Nws tsuas yog tsim nyog ntxiv 1% -2% rau av, uas feem ntau siv los ua cov tshuaj reagent tempering (80% ntawm cov dej ntsiab lus).
Cov neeg kho tshuab siab ntawm daim ntawv zeb zeb sludge dehydration
Papermaking sludge tom qab tempering los ntawm sludge feeding twj rau hauv lub cuab yeej siv dewatering sludge, xws li lub ncov ntawm ultra siab siab sludge nias tshuab. Ua ntej lub sij hawm sludge dewatering ntawm pub twj tso kua mis hauv siab, Thaum twg cov sludge dewatering khoom rau hauv tag nrho kaw sludge, sludge pub twj, sludge drying tshuab pib nrog 6-8MPa siab rau sludge filtrate siab pib ntws los ntawm cov sludge lim xovxwm, av nkos hauv lub ncuav mog qab zib pneumatic tawm hauv qhov kev txiav txim ntawm qhov tsis siv neeg sludge nias tshuab tua, los ntawm cov khoom siv thauj khoom mus rau qhov chaw. Txij thaum ntawd los, cov dej haus ntawm cov kua dej ntim tom qab qhuav av nkos ua av ncuav mog qab zib kom tob tob tob thiab txo qis qoob loo.
Kev muab cov khoom txig pov tseg ntawm cov dej phwj
Kev sib sib zog nqus dewatering ntawm papermaking sludge tuaj yeem xa mus rau hluav taws xob cog kom hlawv fais fab thiab cua sov, uas yuav siv tau los ua khoom siv ua cib thiab cement, thiab tseem tuaj yeem siv ua ib qho kev tshaj tawm. Raws li cov chaw hauv zej zos, daim ntawv zeb ua haujlwm nrog lub tsev cov ntaub ntawv los yog lub tshuab hluav taws xob kom paub txog kev muab cov khoom pov tseg ntawm cov kua dej.
yog li xaiv tus tsim nyog sludge dewatering mesh siv kom lim
