Raws li kev txhim kho cov peev txheej ntxhia, ib qho kev pom tsis pom ntawm cov pa phem yog ntsiag to hem peb ib puag ncig ecological thiab tib neeg kev noj qab haus huv- cov dej khib nyiab hnyav hlau los ntawm kev lag luam mining. Ntawm cov pa phem,Cov tshuaj lom heev xws li arsenic (As), lead (Pb), thiab cadmium (Cd),ib zaug lawv nkag mus rau hauv av thiab dej, ua rau muaj kev puas tsuaj uas ntev - kav ntev thiab feem ntau irreversible. Cov kev kho ib txwm siv, xws li nag lossis daus, feem ntau ua pov thawj tias tsis txaus thaum ntsib cov qauv kev tso tawm ntau zuj zus. Lawv tsis tsuas yog tawm tsam kom tshem tawm tag nrho cov qis- concentration hnyav hlau ions tab sis kuj tsim kom muaj ntau cov tshuaj lom neeg muaj kev phom sij, tsim kom muaj kev pheej hmoo ntawm cov pa phem thib ob. Niaj hnub no, peb yuav delve rau hauv ib qho kev cuam tshuam technology:ceramic membranes rau kev kho dej khib nyiab.
► Dual Barrier: Los ntawm kev cuam tshuam lub cev mus rau qhov tseeb
Yog vim li cas ceramics sawv tawm nyob rau hauv lub tshav pob ntawm cov hlau khib nyiab hnyav nyob rau hauv lawv cov cim thiab muaj zog dual -kev ua haujlwm mechanism.
1. Ib qho kev tiv thaiv lub cev Indestructible
Hauv cov dej khib nyiab tsuas, cov hlau hnyav muaj qee qhovnyob rau hauv daim ntawv ntawm suspended particulates, thaum lwm qhov tuaj yeem hloov mus rau hauvme me khoom precipitateslos ntawm pretreatment (xws li hloov pH thiab tshuaj los nag). Cov tso tsheb hlau luam niaj hnub, uas tso siab rau kev sib cais gravitational, feem ntau tsis muaj txiaj ntsig tiv thaiv cov khoom zoo no, ua rau turbid effluent thiab hnyav hlau ntau tshaj cov qauv.
Ceramic membranes, txawm li cas los xij, yog txawv kiag li. Lawv nto nta cov pores ntawm micron lossis txawm nanometer nplai, ua rau lub cev muaj zog. Thaum cov dej khib nyiab ntws hla ntawm daim nyias nyias, cov dej molecules tuaj yeem hla tau zoo, thaum tag nrho cov hlau hnyav hnyav, cov khib nyiab tshem tawm, thiab cov colloids loj dua li daim nyias nyias qhov pore loj yog khaws cia tag nrho. Qhov no ua kom pom tseeb cov effluent, txiav tawm txoj kev ua pa phem ntawm cov hlau hnyav hnyav ntawm qhov chaw. Raws li lub tuam txhab nrog ntau xyoo kev txawj ntse hauv cov ntaub ntawv ceramic membrane, Taihe Environmental Protection leverages superior mechanical zog thiab ruaj khov filtration precision ntawm nws cov khoom los muab lub hauv paus ruaj khov thiab txhim khu kev qha rau cov hlau hnyav tshem tawm cov dej khib nyiab.
2. Kev nce mus rau yav tom ntej-Nyob rau hauv Smart Capture
Tsuas yog cuam tshuam cov khoom tsis txaus. Qhov kev sib tw ntawm yuav ua li cas kho cov hlau hnyav hnyav ions yog ib qho teeb meem tshwm sim hauv kev kho dej thiab tseem yog tus yuam sij rau kev teb cov lus nug, "Yuav ua li cas tshem tawm cov arsenic yaj ntawm kuv cov dej?" Txog qhov kawg no, txiav- kev tshawb fawb ntug hauv kev lag luam yog tsom raufunctionalized hloov kho ceramics.
Xav txog tej yam endowing ceramic membrane nrog lub peev xwm ntawm "smart recognition." Los ntawm cov txheej txheem kev hloov kho saum npoo av, nws muaj peev xwm "graft" cov pab pawg ua haujlwm nrog kev sib raug zoo rau cov hlau hnyav tshwj xeeb rau saum npoo los yog hauv qhov pores ntawm cov khoom siv membrane. Hom kab xev no rau cov hlau hnyav ua haujlwm zoo li lub hom phiaj hlau nplaum, xaiv adsorbing yaj ions xws li txhuas thiab cadmium los ntawm dej. Qhov no ua tiav qhov dhia los ntawm "passive interception" mus rau "active capture." Cov txheej txheem tshem tawm cov hlau xaiv no ua rau muaj txiaj ntsig zoo rau kev kho mob thiab kev ua tau zoo, sawv cev rau kev taw qhia tseem ceeb rau kev ua tiav ultra- emissions qis thiab cov peev txheej rov qab los rau yav tom ntej.
► "Ceramic Membrane +" Hybrid Txheej Txheem: Yeej -Yeej rau Kev Ua Tau Zoo thiab ruaj khov
Ib qho thev naus laus zis feem ntau tsis txaus los daws qhov nyuaj thiab sib txawv ntawm cov dej khib nyiab, tshwj xeeb tshaj yog rau kev ua haujlwm nyuaj ntawm kev kho cov kua qaub mine. Yog li ntawd, cov txheej txheem kev sib koom ua ke nyob ib puag ncig ceramics tau tshwm sim. Ib txoj kev kho mob feem ntau muaj xws li:
1. Pretreatment Unit
Los ntawm txoj kev xws li kev hloov pauv pH thiab tshuaj siv tshuaj, yaj cov hlau hnyav hnyav tau hloov mus rau hauv cov dej tsis sib haum.
2. Ceramic Membrane Core Separation Unit
Qhov no yog "lub plawv" ntawm tag nrho cov txheej txheem, zoo sib cais cov hnyav hlau precipitates generated nyob rau hauv lub dhau los theem thiab ua ib tug ntshiab, ruaj khov, siab - zoo filtrate. Nws muaj zog tiv thaiv -fouling zog thiab yooj yim ntawm kev tu hauv online kom paub meej lub sijhawm ntev -, ruaj khov ua haujlwm ntawm lub cev.
3. Kev kho mob siab heev thiab rov siv dua
Cov dej zoo tom qab kev kho cov kab mob ceramic yog twb ntshiab txaus rau kev tso tawm ncaj qha raws li cov qauv, lossis nws tuaj yeem xa mus rau cov chav kho mob tom ntej xws li rov qab osmosis (RO) rau kev tshem tawm ntsev ntxiv, thaum kawg ua tiav xoom kua paug mining thiab rov ua dua dej.
Kos rau nws qhov kev paub ntau yam engineering hauv kev kho cov txheej txheem membrane, Taihe Environmental Protection ua tau zoo ntawm kev txiav cov noCeramic Membrane +kev daws teeb meem raws li cov kev xav tau tshwj xeeb ntawm cov chaw sib txawv mining, xws li Technology rau kev kho cov hlau lead-zinc mine dej khib nyiab, kom ntseeg tau tias txhua tee dej tau txais kev kho mob zoo tshaj plaws.
► Tshaj Li Kev Ua Raws Cai: Nkag mus rau Lub Sij Hawm Tshiab ntawm Green Mining
Daim ntawv thov ntawm ceramic membrane tshuab tau coj cov kev hloov pauv hloov hauv kev tswj cov dej khib nyiab mining. Nws tsis yog tsuas yog ib qho kev sib tw muaj zog rau lub npe ntawm Qhov Zoo Tshaj Plaws muaj thev naus laus zis rau kev tswj hwm cov pa phem cadmium, tab sis yog qhov kev txhim kho ntawm tag nrho cov kev kho mob paradigm.
Nws tau raug pov thawj nyob rau hauv kev xyaum hais tias kev siv cov txheej txheem nyob rau hauv cov khoom siv ceramic tuaj yeem txo qhov ntim ntawm cov tshuaj sludge generated, ua rau txo qis cov nqi pov tseg thiab ib puag ncig kev pheej hmoo cuam tshuam nrog cov pov tseg phom sij. Tsis tas li ntawd, vim nws muaj peev xwm ua tau zoo heev, cov hlau hnyav uas khaws cia tau zoo dua rau kev rov qab los ntawm cov hlau muaj txiaj ntsig, tig pov tseg rau hauv tus nqi thiab tsim cov txiaj ntsig nyiaj txiag ntxiv. Nws ultra- lub neej ua haujlwm ntev thiab kev siv hluav taws xob qis dua kuj ua rau lub tuam txhab kev nqis peev ib puag ncig zoo dua.
Hauv kev xaus,ceramic membranes rau kev kho dej khib nyiabthev naus laus zis, los ntawm kev tsim txiaj ntawm nws qhov siab - kev ua tau zoo ntawm kev sib cais, kev ruaj ntseg zoo, thiab kev sib raug zoo nrog lwm cov txheej txheem, yog pab cov tuam txhab mining hloov pauv los ntawm lub luag haujlwm ntawm kev ua raws li cov txheej txheem mining effluent mus rau ib qho ntawm kev tswj hwm ib puag ncig thiab kev siv peev txheej. Qhov no tsis yog tsuas yog lub cuab yeej muaj zog rau kev xaus kev npau suav phem ntawm cov hlau hnyav hnyav, tab sis kuj yog ib txoj hauv kev tseem ceeb rau kev cog qoob loo ntsuab thiab kev lag luam mining.
