Manganese xuab zeb
Cov tsos ntawm manganese xuab zeb lim cov khoom yog xim av dub, ze li ntawm lub voj voog, thiab cov khoom tseem ceeb yog manganese dioxide, nrog rau cov ntsiab lus ntawm 35% mus rau 45%. Manganese xuab zeb lim cov khoom yog ua los ntawm cov khoom zoo manganese xuab zeb, muaj zog siv zog, tsis yooj yim tawg, thiab insoluble hauv dej. Ua tiav rau hauv cov xuab zeb los ntawm cov txheej txheem xws li dej ntxuav, sib tsoo, crushing, ziab, sib nqus sib nqus, tshuaj ntsuam xyuas, thiab tshem tawm plua plav. Tom qab ntawd sib tov cov txheej txheem manganese xuab zeb raws li ib qho kev gradation.
Nws muaj qhov zoo tshaj plaws gradation piv rau kev kho dej lim xov xwm, uas tso cai rau nws kom muaj qhov siab tshaj plaws ntawm thaj chaw tshwj xeeb, qhov muaj peev xwm cuam tshuam cov pa phem tshaj plaws, qhov siab tshaj plaws oxidation catalytic nyhuv, thiab qhov tsawg kawg nkaus backwash poob tus nqi ib chav tsev ntim.

Manganese Sand Rau Dej Softening
Nyob rau hauv tus txheej txheem ntawm softening dej zoo, firstly, vim lub sij hawm kev kho mob ntawm manganese xuab zeb softening dej, qhov thib ob, vim muaj cov hlau oxides xws li hlau, ferric oxide, thiab ferrous oxide nyob rau hauv dej, ntau yam khoom yog tov. , uas zoo heev txo cov hlau thiab manganese tshem tawm cov nyhuv ntawm manganese xuab zeb.
Yog li ntawd, txhawm rau ua kom cov hlau thiab manganese tshem tawm cov nyhuv ntawm manganese xuab zeb, cov txheej txheem kho aeration yuav tsum tau ntxiv ua ntej txheej txheem manganese xuab zeb. Txhawm rau ua tiav cov txiaj ntsig zoo tshaj plaws hauv kev tshem tawm cov hlau thiab manganese! Anaerobic aerobic facultative biological kev kho cov txheej txheem nrog ntau qhov sib txawv tuaj yeem xaiv tau raws li cov ntaub ntawv sib txawv ntawm cov dej zoo. Cov txheej txheem no tsis tsuas yog muaj cov txiaj ntsig zoo ntawm denitrification thiab phosphorus tshem tawm, tab sis kuj tuaj yeem decompose siab molecular hnyav organic teeb meem rau hauv qis molecular hnyav organic teeb meem uas yooj yim rau aerobic biodegradation.
Yam ntxwv
- Yog hais tias manganese muaj nyob rau hauv cov dej nyoos, manganese xuab zeb muaj cov nyhuv demanganization.
- Yog tias qhov xav tau ntawm cov tshuaj dawb chlorine raug kuaj pom hauv cov dej nyoos MnO₂・H₂O (manganese dioxide hydrate) yog rov tsim dua los ntawm oxidization ntawm manganese hauv dej nyoos thiab nws coats saum npoo ntawm manganese xuab zeb. Tom qab ntawd, nws yuav zoo ib yam li manganese xuab zeb. Yog li ntawd, kev sib cuag oxidation muaj peev xwm (demanganization peev) ntawm manganese xuab zeb yog khaws cia.
- Cov manganese muaj nyob hauv peb cov khoom yog 0.3mg/g lossis ntau dua.
- Manganese xuab zeb tuaj yeem siv rau demanganization nrog lub tshuab pom sai.
