Yuav ua li cas cod tuaj yeem ib qho tuj ntawm activated carbon adsorb?

Granular ua haujlwm carbon
Granular tshuabs tau siv cov pa hluav taws xob feem ntau siv nyob rau hauv kev kho cov txheej txheem txuas ntxiv ntawm kev siv khoom pov tseg vim nws txoj kev ruaj khov thiab yooj yim dua tshiab.

Adsorption muaj peev xwm: Cov adsorption muaj peev xwm ntawm Granular antourated carbon feem ntau feem ntau nyob ib ncig ntawm 10%.

Adsorption muaj peev xwm: ib tuj ntawm granular antenated carbon tuaj yeem adsorb kwv yees li 0.1 tuj ntawm Cod.

2. Hmoov actively acbon
Hmoov kom tau cov pa roj carbon tau dav hauv kev siv cov tshuab vim nws qhov loj tshwj xeeb thaj chaw thiab cov qauv adsorption.

Adsorption muaj peev xwm: Cov adsorption muaj peev xwm ntawm cov hmoov ua haujlwm roj carbon ntau yog feem ntau ntawm 10% thiab 35%.

Adsorption muaj peev xwm: ib tuj ntawm hmoov activated carbon tuaj yeem adsorb thiab tshem tawm 0.1 txog 0.35 tons ntawm cod. Tus nqi tshwj xeeb nyob ntawm cov dej ua kom zoo thiab cov txheej txheem tsis sib xws.
Ii. Qhov tseem ceeb cuam tshuam rau cov cod adsorption muaj peev xwm ntawm cov carbon accon
Adsorption cov txiaj ntsig ntawm cov carbon ua haujlwm rau COD yog txwv los ntawm ntau yam sab hauv thiab sab nraud. Hauv qab no yog qhov cuam tshuam tseem ceeb:

1. Qhov ntsuas ntawm cov pa roj carbon ua haujlwm
Iodine Tus nqi: Iodine tus nqi yog qhov taw qhia tseem ceeb rau kev ntsuas qhov muaj peev xwm ntawm cov carbon accon. Feem ntau, ntau dua iodine tus nqi, lub zog muaj zog rau adsorb cod.

Tus qauv loj: Qhov feem sib piv ntawm cov micropores rau mesopores txiav txim siab cov txiaj ntsig adsorption ntawm cov pa hluav taws xob sib txawv ntawm cov pa hluav taws xob sib txawv.

2. Cov khoom siv tsis zoo
Cod concentration: Qhov siab dua tus lej ntawm cov cim hauv cov dej nyoos, qhov qis dua adsorption efficiency rau ib chav ntawm cov carbon ua haujlwm.

Cov Txheej Txheem Iurfity: Wastewater muaj roj thiab ua cov orge acorgic yuav nyob cov adsorption chaw ntawm actived carbon, txo nws lub peev xwm rau ADSORRB COD.

3. Adsorption Kev Mob
PH TSEG: Cov kev tshaj tawm zoo tshaj plaws p P feem ntau yog nyob rau hauv acidic acidic tej yam kev mob. Tshaj p p p tuaj yeem ua rau tsis muaj zog tshaj tawm cov adsorption muaj peev xwm ntawm cov carbon actived.

Qhov kub thiab txias: Kev ntsuas kub nruab nrab tuaj yeem txhim kho kev ua tiav adsorption, tab sis kev kub siab ntau dhau yuav ua rau poob rau kev ua tiav kev ua tiav.

Stirring qhov kev siv: Nruab nrab stirring pab txhawb kev sib cuag ntawm cov carbon thiab dej khib nyiab, yog li kev txhim kho cov adsorpticy.

III. Kev sib txawv ntawm kev ua tiav kev ua tiav
Kev ploj zuj zus ntawm chav kawm adsorption efficiency
Nrog rau kev nce ntau ntawm kev ua haujlwm ntawm cov pa roj carbon, tab sis kev ua tiav kev txhim kho ib chav ntawm cov pa roj carbon ua kom tsawg dua. Qhov tshwm sim no los ntawm:

Cov pores ntawm actived carbon tau maj mam nyob, thiab adsorption muaj peev xwm ntawm cov ntxig rau cov cod tsis muaj zog.

Qhov seem ntawm cov kev xav hauv cov dej khib nyiab txo qis, thiab kev tshaj tawm kev tawm tsav tsheb txo (ua kom cov pa roj carbon tsis muaj peev xwm adsorb cod rau 0mg / l).

2. Muaj feem siv cov lej cim
Cov adsorption muaj peev xwm ntawm cov pa roj carbon ua haujlwm haum rau cov neeg khib nyiab nrog lub cod concentration hauv qab 600 mg / l. Thaum cov cod concentration yog dhau lawm, cia siab rau ntawm cov carbon ua haujlwm nyuaj rau kev tshem tawm cov nyhuv zoo tshaj plaws. Feem ntau, nws yog ib qho tsim nyog los ua ke lwm cov txheej txheem (xws li coagulation sedimation, txheeb raws roj ntsha, thiab lwm yam).

IV. Muab tshuaj thiab ua haujlwm txheeb xyuas hauv cov ntawv thov siv
Cov hauv qab no yuav siv cov thee ntawm - raws cov hmoov carbon (iodine muaj nuj nqis 800 m

Thawj qhov kev xav ntawm lub siab yog tsawg dua lossis sib npaug nrog 400 mg / l
Kev: Cov kev tshuaj ntau ntau ntawm cov hmoov ua haujlwm rau cov pa roj carbon yog 400-600 ppm.

Kev Kho Mob: Tom qab kev kho mob, tus lej ntawm effluent tuaj yeem txo qis rau hauv qab 200 mg / l.

Tus thawj zaug concentration ntawm cov lej yog 400 rau 600 mg / l
Kev: Nws yuav tsum tau nce ntxiv nce rau 600-800 PPM.

Kev Kho Mob: Tus lej ntawm effluent feem ntau yuav raug txo qis rau hauv qab 300 mg / l.

3. High {{{-}} recretration lim dej (cod> 1000 mg / l
Cov txheej txheem qhia: Txais yuav cov txheej txheem sib xyaw ua ke ntawm "Pretreatment + ACTIVICED cov adsorption". Pretricatment yog siv los txo cov cim cod concentration rau ntau qhov haum rau kev ua haujlwm rau cov carbon adsorption.

V. Yuav ua li cas thiaj ua tau zoo tshaj tawm cov txiaj ntsig adsorption ntawm actived carbon
Txhawm rau kom muaj kev sib tw ua kev kawm ntawm Shufang qhib cov pa roj carbon thiab txhim kho lub cim tshem tawm, cov hauv qab no tuaj yeem txiav txim siab:

1. Xaiv hom kev ua haujlwm rau cov zaub mov ua haujlwm
Xaiv cov xim av los yog cov hmoov ua haujlwm rau cov pa roj carbon raws cov yam ntxwv ntawm cov dej khib nyiab. Piv txwv li, granular tshuab txais yog haum rau cov tshuab txuas ntxiv, thaum cov hmoov ua haujlwm tau zoo dua rau kev kho mob sib txawv lossis ua ke nrog lwm cov txheej txheem.

2. Tswj cov tshuaj
Kho cov tshuaj raws li cov dej ua kom zoo thiab kho cov hom phiaj kom tsis txhob muaj ntau npaum li cas, uas yuav ua rau muaj cov khoom pov tseg lossis cov adsorption ntau.

3. Hloov lossis rov tsim cov pa roj ua kom tiav raws sijhawm
Kev kawm tiav kev ua yeeb yam ntawm activate carbon maj tsis tsawg ntawm lub sij hawm siv tau ntawm lub sijhawm, yog li nws yuav tsum tau hloov lossis rov tsim dua tshiab los tswj cov nyhuv kho.

4. Daim ntawv thov ntawm cov txheej txheem ua ke
Rau siab -}}}}} awnize kho mob, kev kho mob carbon + biochemical kev kho mob "tuaj yeem tau txais los txhim kho kev tshem tawm tag nrho.

VI. Kev Ntsuas Xyuas
Tus nqi ntawm ib qho ntawm ib qho tuj ntawm cov pa roj carbon monoxide tuaj yeem adsorb nyob ntawm cov nyhuv sib xyaw ua ke ntawm ntau yam. Nws yog qhov zoo tshaj plaws los ua kev sim los sim cov kev pom zoo ua ntej ntxiv nws. Xaiv hom kev ua haujlwm zoo, ua kom zoo dua cov txheej txheem kho thiab tsim nyog tswj cov tshuaj tuaj yeem txhim kho qhov kev tshem tawm ntawm cov cim. Nws tseem tuaj yeem ua tiav txoj kev daws teeb meem kev lag luam zoo tshaj plaws rau kev kho kom tau txais kev lag luam pov tseg.
