Quartz xuab zeb lim
Quartz xuab zeb lim, raws li lub npe qhia, yog ntim nrog quartz xuab zeb lim khoom. Quartz xuab zeb feem ntau cuam tshuam cov impurities xws li sediment hauv dej los ntawm kev cuam tshuam thiab pom. Quartz xuab zeb txawv ntawm cov xuab zeb zoo tib yam vim tias nws muaj zog hardness thiab cov khoom tuaj yeem ua tau zoo. Yog tias siv quartz xuab zeb zoo tib yam, nws yooj yim tawg tom qab ntxuav thiab ntxuav, thiab cov xuab zeb poob yog qhov hnyav dua lub sijhawm. Txawm hais tias manganese xuab zeb muaj qhov ntim siab, nws lub zog tsis muaj zog li quartz, yog li nws tsis zoo li quartz xuab zeb hauv kev lim thiab tshem tawm impurities xws li hlau thiab manganese.
Manganese xuab zeb lim
Manganese xuab zeb lim, tseem hu ua, feem ntau yog siv los tshem tawm cov hlau thiab manganese ions. Nws tsuas yog lim hlau thiab manganese hauv dej los ntawm kev cuam tshuam thiab adsorption. Hlau thiab manganese ions tuaj yeem lim thiab tshem tawm los ntawm manganese xuab zeb tom qab aeration oxidation.
Cov dej uas muaj hlau thiab manganese siab feem ntau yog siv los oxidize yaj divalent hlau los yog divalent manganese rau hauv insoluble trivalent hlau los yog tetravalent manganese tebchaw nyob rau hauv qhov kev txiav txim ntawm oxidation. Lub adsorption pom ntawm manganese xuab zeb lim tuaj yeem tshem tawm cov hlau thiab manganese. Cov tshuaj tiv thaiv uas tshwm sim thaum nws cov txheej txheem oxidation yog raws li nram no:
4Fe2++O2+10H2O=4Fe(OH)3+8H+
2Mn2++O2+2H2O=2MnO2+4H+
Kev khiav hauj lwm tsis ntawm quartz xuab zeb lim thiab manganese xuab zeb lim
Zuag qhia tag nrho, quartz xuab zeb lim thiab quartz xuab zeb lim ua haujlwm nyob rau hauv tib lub sijhawm, nrog dej nkag siab ntawm 3-4kg thiab qhov kub thiab txias. Lub tank lim feem ntau yog ua los ntawm cov hlau tsis muaj steel thiab carbon steel hauv ob sab phlu cov ntaub ntawv roj hmab, lossis epoxy los tiv thaiv corrosion. Qhov sib txawv tseem ceeb yog qhov pom kev ntws sib txawv. Qhov siab tshaj plaws ntws ntawm quartz xuab zeb lim tuaj yeem ncav cuag 20m / h, thaum lub siab tshaj plaws ntws ntawm manganese xuab zeb lim yog 10m / h. Yog li ntawd, thaum soj ntsuam nrog tib tus nqi ntawm cov dej, txoj kab uas hla ntawm quartz xuab zeb lim tank yuav tsum me me thiab cov nyiaj ntawm quartz xuab zeb filling yuav tsum tsawg dua. Hais txog cov khoom siv lim dej, manganese xuab zeb muaj cov khoom siv lim dej ntau dua thiab cov ntim ntim ntau dua. Yog li, hloov quartz xuab zeb lim nrog manganese xuab zeb lim kuj yog qhov tsis zoo los ntawm kev lag luam kev xav. Los ntawm kev pom ntawm kev pom, quartz xuab zeb lim tsis tuaj yeem hloov cov lim dej manganese vim tias lawv cov txiaj ntsig ntawm kev tshem cov hlau thiab manganese yog qhov qis dua rau cov lim dej manganese.
