Nyob rau hauv ob lub ntsiab lus ntawm accelerating ntiaj teb no industrialization thiab nce dej tsis txaus, kev kho dej khib nyiab yog ua raws li ib tug loj paradigm hloov. Qhov kawg ib txwm muaj- ntawm- kev kho cov yeeb nkab kev xav tau hloov pauv los ntawm kev mus tom ntej- saib lub tswv yim kev lag luam ncig, uas tsis pom cov dej khib nyiab ua raws li tus nqi tab sis yog "lub nroog mine" raug siv. Nyob rau hauv no transformation, advanced technologies tsom rauZero Liquid Discharge (ZLD)thiabdej khib nyiab valorizationtau ua qhov tseem ceeb. Ntawm lawv, cov txheej txheem ceramic membrane ntawm nws tus kheej tsim los ntawm peb lub tuam txhab, Taihe Environmental Protection, yog ua rau kev hloov pauv ntsuab.los ntawm "emission reduction" mus rau "revenue generation"nrog nws cov kev ua tau zoo heev.
► 1. Cov kev sib tw thiab cov cib fim hauv kev kho dej hauv kev lag luam
► 1.1 Bottlenecks of Traditional Technologies
Tau ntev, kev lag luam kev lag luam feem ntau ntsib kev lag luam- cov kev sib tw thoob plaws thaum kho cov dej khib nyiab nyuaj nrog cov dej qab ntsev thiab cov pa phem ntau, xws li cov nqi kho mob siab, kev tsis zoo ntawm lub cev, thiab cov teeb meem nrog cov khoom siv membrane zoo li yooj yim fouling thiab luv lifespan. Tshwj xeeb tshaj yog nyob rau hauv hnyav kev khiav hauj lwm tej yam kev mob nrogkub siab, muaj zog acids, los yog muaj zog alkalis, kev ua tau zoo ntawm cov pa organic membrane cov ntaub ntawv degrades sai heev. Kev hloov pauv thiab kev saib xyuas tsis yog tsuas yog ua kom lub nra hnyav ua haujlwm xwb tab sis kuj txwv kev txhim kho ntxiv ntawm cov dej rov qab siv dua, ua rau kev kho cov dej khib nyiab ib qho kev siv nyiaj hnyav hauv kev lag luam.
► 1.2 Kev Pom Zoo Tshiab los ntawm Zero Liquid Discharge (ZLD)
Qhov tshwm sim ntawm Zero Liquid Discharge (ZLD) systems muaj ib txoj hauv kev tshiab los daws cov teeb meem no.Nws yog lub hom phiaj kom rov qab siv dej tag nrho thiab rov qab tau cov khoom yaj hauv cov khoom siv los ntawm kev kho ntau yam - theem.Qhov no tsis tsuas yog daws qhov teeb meem ntawm cov dej khib nyiab nkaus xwb tab sis, qhov tseem ceeb tshaj, nws qhib lub qhov rooj kom rov qab tau siab dua - dej huv, ntsev, thiab lwm yam tshuaj muaj txiaj ntsig los ntawm cov dej khib nyiab, tsim cov nqi tshiab rau cov lag luam. Tus yuam sij kom ua tiav kev ua tau zoo thiab ruaj khov ZLD yog nyob rau hauv kev xaiv cov thev naus laus zis rau pem hauv ntej - theem kawg concentration.
► 2. Ceramic Membranes: Cov Txheej Txheem Txheej Txheem Txhawb ZLD thiab Valorization
Raws li ib qho tseem ceeb ntawm ZLD systems, kev xaiv ntawm siab -cov ntaub ntawv membrane yog qhov tseem ceeb. Cov khoom siv tshwj xeeb ceramic membrane thiab membrane sib cais tshuab yog los ntawm peb lub tuam txhab, Taihe Environmental Protection, tau raug soj ntsuam raws li thoob ntiaj teb qib siab los ntawm cov koom haum kev lag luam, muab kev txhawb zog rau kev kov yeej cov teeb meem ntawm cov dej khib nyiab valorization.
► 2.1 Exceptional Material Properties
Piv nrog rau cov ntaub ntawv membrane cov pa, qhov tseem ceeb ntawm cov khoom siv ceramic yog nyob rau hauv lawv qhov tsis sib xws. Cov txheej txheem porous ceramic membrane, ua los ntawm cov ntaub ntawv tsis muaj zog, ua rau lawv muaj kev tiv thaiv zoo rau qhov kub thiab txias, muaj zog acids thiab alkalis, roj fouling, thiab tshuaj lom neeg corrosion. Qhov no txhais tau tiaslawv tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv qhov chaw muaj kev lag luam huab cua uas cov thev naus laus zis niaj hnub yuav ua tsis tiav.Tsis tas li ntawd, lawv cov neeg kho tshuab siab zog thiab muaj zog tiv thaiv - fouling muaj peev xwm ua rau lub neej ua haujlwm ob peb zaug ntawm cov pa hauv nruab nrog cev, txo qis cov nqi tag nrho ntawm lub neej. Cov yam ntxwv muaj zog thiab ruaj khov no ua rauceramic membranes rau kev kho dej khib nyiabkev xaiv txhim khu kev qha.
► 2.2 Lub luag haujlwm tseem ceeb hauv ZLD Systems
Hauv ZLD cov txheej txheem tsom rau cov peev txheej rov qab los, tubular ceramic membrane modules feem ntau ua raws li "tus neeg ua haujlwm tseem ceeb." Thaum lub sij hawm ua ntej -kev kho mob thiab cov concentration, cov txheej txheem ceramic membrane tuaj yeem tshem tawm cov khib nyiab, colloids, thiab loj -molecule organic teeb meem. Qhov no muab cov khoom noj ruaj khov thiab huv si rau qhov sib sib zog nqus tom ntej- cov kev kho mob xws li rov qab osmosis, tiv thaiv kev scaling thiab fouling ntawm downstream membrane cov ntsiab lus thiab ua kom lub sij hawm ntev -, ruaj khov ua haujlwm ntawm tag nrho ZLD system. Lawv cov yam ntxwv ntawm cov dej ntws siab thiab kev siv hluav taws xob tsawg kuj ua rau cov khoom siv ceramics rau cov dej khib nyiab rov qab siv nyiaj ntau dua.
► 3. Muab pov tseg rau hauv tus nqi: Los ntawm Lub Chaw Nqis mus rau Lub Chaw Ua Haujlwm
Kev siv cov txheej txheem ceramic membrane tau hloov kho cov txiaj ntsig ntawm kev kho dej khib nyiab. Los ntawm kev sib txuas siab -kev ua tau zoo ceramic membrane pom nrog cov txheej txheem tom ntej xws li evaporation thiab crystallization, cov tuam txhab tuaj yeem ua tiav lub hom phiaj ntawm "tig pov tseg rau hauv tus nqi."
Nyob rau hauv lub siab -salinity concentration theem, qhov ruaj khov kev ua tau zoo ntawm ceramics ua kom ntseeg tau tias brine tuaj yeem ua kom muaj txiaj ntsig zoo, tsim cov xwm txheej zoo rau kev sib cais ntsev tom qab thiab crystallization.Lub kaw lus kawg tsis tsuas yog tsim cov dej siab zoo - zoo dua qub (raws li kev txhawb nqa los ntawm kev tshawb pom hauv thiab uas tuaj yeem rov qab siv tau hauv cov txheej txheem tsim khoom, tab sis kuj tseem cais thiab ua kom huv huv siab- tus nqi los ntawm - cov khoom xws li cov ntsev thiab tshuaj lom neeg.Cov peev txheej zoo li no tuaj yeem ua tau raws li kev lag luam tus kheej cov kev xav tau, txo cov nqi ntawm cov khoom siv raw, los yog muag raws li cov khoom lag luam, yog li hloov pauv qhov kev siv nyiaj ib puag ncig rau hauv kev lag luam rov qab. Cov qauv tshiab no yog qhov zoo tshaj plaws embodiment ntawm lub tswv yim tom qab ceramics rau cov dej khib nyiab rov qab siv dua.
► 4. Lub Ntiaj Teb Lub Zeem Muag thiab Cov Txheej Txheem Txheej Txheem
Nrog rau kev loj hlob thoob ntiaj teb tseem ceeb ntawm kev ruaj ntseg dej thiab kev lag luam ncig, tshwj xeeb tshaj yog nyob rau hauv dej- thaj chaw tsis tshua muaj xws li Asia thiab Middle East, kev lag luam xav tau kev kho dej kom zoo tau loj hlob ntawm tus nqi tsis tau muaj dua.Kos rau ntawm daim ntawv thov kev paub ntau ntxiv hauv ntau qhov kev lag luam suav nrog tshuaj lom neeg, thermal zog, thiab cov tshuaj, peb lub tuam txhab, Taihe Environmental Protection, tau ua tiav ntau lub tuam txhab loj hauv tsev nrog kev sib koom ua ke ntawm cov dej khib nyiab valorization cov kev daws teeb meem ntawm cov khoom siv ceramic.
Tsim los ntawm cov txheej txheem thev naus laus zis paub tab thiab cov ntaub ntawv kawm tiav, tam sim no peb tab tom tig peb lub siab mus rau kev lag luam thoob ntiaj teb. Hauv cov tebchaws Esxias sab hnub tuaj xws li Indonesia thiab Malaysia, kev tsis sib haum xeeb ntawm kev tsim kho kev lag luam sai thiab kev tiv thaiv dej tau dhau los ua qhov tseem ceeb. Peb tau cog lus los nthuav qhia cov txheej txheem ceramics siab heev siv rau kev kho dej rau cov cheeb tsam no, pab cov neeg koom tes hauv zos tsim kev tswj dej kom ruaj khov. Los ntawm kev txhawb nqa peb cov khoom siv hluav taws xob rau kev kho dej, peb tab tom xa tawm tsis yog cov cuab yeej siv xwb, tab sis kuj yog ib qho kev xav ntawm ib puag ncig zoo ntawm kev hloov ntawm "emission txo" mus rau "nyiaj tau txais txiaj ntsig", pab kev lag luam thoob ntiaj teb ua tiav kev yeej- yeej qhov xwm txheej rau kev loj hlob ntsuab thiab kev loj hlob.
Hauv kev xaus, kev siv cov peev txheej thiab cov txiaj ntsig los ntawm cov dej khib nyiab tau dhau los ua qhov kev xav tsis thoob rau kev tsim kho kev lag luam yav tom ntej. Sawv cev los ntawm peb lub tuam txhab, Taihe Environmental Protection, siab heevceramic membranes rau cov dej khib nyiab rov qab siv duathev naus laus zis tau qhib txoj hauv kev tshiab rau kev txhim kho kom ruaj khov thiab kev lag luam ua tiav rau cov neeg siv khoom lag luam thoob ntiaj teb los ntawm nws cov kev ua tau zoo thiab cov qauv siv tshiab, ua tiav qhov kev sib koom ua ke ntawm kev tiv thaiv ib puag ncig thiab cov txiaj ntsig kev lag luam.
