Cov pa roj carbon activated tau siv dav hauv peb lub neej, thiab nws cov peev txheej zoo adsorption yog nrov heev.Lub tshuab lim carbon lim dej yog lub tshuab lim dej ntawm lub tank lub cev.Sab nrauv feem ntau yog ua los ntawm iav fiber reinforced yas, thiab sab hauv yog ntim nrog cov pa roj carbon activated, uas tuaj yeem lim cov kab mob thiab qee cov hlau hnyav hauv dej, thiab tuaj yeem txo cov xim ntawm cov dej.Yog li cas no activated carbon lim ua haujlwm li cas?
Lub hauv paus ntsiab lus ntawm adsorption ntawm cov pa roj carbon activated yog tsim ib txheej ntawm qhov sib npaug ntawm qhov sib npaug ntawm qhov chaw ntawm nws cov khoom.Qhov loj ntawm cov pa roj carbon activated kuj muaj qhov cuam tshuam rau lub peev xwm adsorption.Feem ntau, qhov me me ntawm cov pa roj carbon activated, qhov loj dua qhov lim cheeb tsam.Yog li ntawd, hmoov activated carbon muaj qhov loj tshaj plaws tag nrho cheeb tsam thiab qhov zoo tshaj plaws adsorption nyhuv, tab sis hmoov activated carbon yooj yim ntws mus rau hauv lub tank dej nrog dej, uas yog ib qho nyuaj rau tswj thiab tsis tshua muaj siv.Granular activated carbon tsis yooj yim rau ntws vim yog tsim cov khoom, thiab impurities xws li cov organic teeb meem hauv dej tsis yooj yim los thaiv hauv activated carbon lim txheej.Nws muaj peev xwm adsorption muaj zog thiab yooj yim nqa thiab hloov.
Lub peev xwm adsorption ntawm activated carbon yog proportional rau lub sij hawm sib cuag nrog dej.Lub sijhawm sib cuag ntev dua, qhov zoo dua qhov lim dej zoo.Lus Cim: Cov dej lim dej yuav tsum ntws tawm ntawm txheej lim maj mam.Cov pa roj carbon activated tshiab yuav tsum tau ntxuav kom huv ua ntej siv thawj zaug, txwv tsis pub yuav muaj dej dub ntws tawm.Ua ntej cov pa roj carbon activated loaded rau hauv lub lim, ib daim txhuam cev nrog lub thickness ntawm 2 mus rau 3 cm yuav tsum tau ntxiv rau hauv qab thiab sab saum toj kom tsis txhob muaj kev nkag mus ntawm cov khoom loj ntawm impurities xws li algae.Tom qab siv cov pa roj carbon activated rau 2 mus rau 3 lub hlis, yog tias cov nyhuv lim dej txo qis, nws yuav tsum tau hloov.Tshiab activated carbon, sponge txheej yuav tsum tau hloov tsis tu ncua.
Cov khoom siv lim dej hauv cov tshuab lim cua lim adsorber tuaj yeem ntim nrog quartz xuab zeb nrog qhov siab ntawm 0.15 ~ 0.4 meters hauv qab.Raws li cov txheej txheem txhawb nqa, cov khoom ntawm quartz xuab zeb tuaj yeem yog 20-40 hli, thiab cov xuab zeb quartz tuaj yeem sau nrog granular activated carbon ntawm 1.0-1.5 meters.raws li txheej lim.Lub filling thickness feem ntau yog 1000-2000mm.
Ua ntej lub tshuab lim carbon lim dej raug them, cov khoom siv lim hauv qab quartz xuab zeb yuav tsum raug kuaj xyuas kev ruaj ntseg ntawm cov tshuaj.Tom qab soaking rau 24 teev, cov kev cai hauv qab no tau ntsib: qhov nce ntawm tag nrho cov khib nyiab tsis pub tshaj 20mg / L.Kev nce hauv cov pa oxygen yuav tsum tsis pub tshaj 10 mg / L.Tom qab soaking hauv alkaline nruab nrab, qhov nce ntawm silica tsis tshaj 10mg / L.
Cov activated carbon lim quartz xuab zeb yuav tsum tau muab ntxuav kom zoo tom qab ntxuav rau hauv cov khoom siv.Cov dej ntws yuav tsum tau ntxuav los ntawm sab saum toj mus rau hauv qab, thiab cov dej qias neeg yuav tsum tau tawm hauv qab kom txog thaum cov dej ntws tawm kom meej.Tom qab ntawd, granular activated carbon lim khoom yuav tsum tau thauj khoom, thiab tom qab ntawd ntxuav.Cov dej ntws los hauv qab mus rau hauv qab.Yaug rau saum, cov dej qias neeg yog drained los ntawm sab saum toj.
Kev ua haujlwm ntawm activated carbon lim yog tsuas yog tshem tawm macromolecular organic teeb meem, hlau oxide thiab cov chlorine seem.Qhov no yog vim hais tias cov organic teeb meem, residual chlorine thiab hlau oxides tau yooj yim lom cov ion pauv resin, thaum residual chlorine thiab cationic surfactants yuav tsis tsuas lom cov resin, tab sis kuj ua rau cov membrane qauv thiab ua rau lub rov qab osmosis membrane tsis zoo.
Activated carbon lim tau siv dav hauv kev lag luam.Lawv tuaj yeem tsis tsuas yog txhim kho cov dej zoo ntawm cov effluent, tab sis kuj tseem tiv thaiv kev ua qias tuaj, tshwj xeeb tshaj yog cov pa oxygen residual pa phem ntawm cov txheej txheem rov qab osmosis membrane thiab ion exchange resin.Activated carbon lim tsis tsuas yog muaj kev ua haujlwm siab, tab sis kuj muaj cov nqi khiav lag luam qis, zoo effluent zoo thiab zoo filtering nyhuv.
Yog tias koj xav tau, tsuas yog nyem lub pob hauv qab no.
