Taw qhia
Tsis ntev los no, peb lub tuam tsev hauv lub tebchaws tau sib koom ua ke "Action Plan for the Development of Seawater Desalination Industry," uas qhia meej tias los ntawm 2030, tag nrho cov nplai ntawm seawater desalination nyob rau hauv Suav teb yuav tshaj 4.5 lab tons / hnub, nrog rau ntxiv 1.5 lab tons / hnub ntawm lub peev xwm ntxiv nyob rau hauv tsib xyoos tom ntej. Cov dej hauv nroog, kev ua neej nyob hauv koog pov txwv, thiab kev lag luam ntug hiav txwv yuav pom txhua qhov kev nthuav dav ib txhij thiab nthuav dav, ua tiav kev lag luam muaj nqis txog kaum lab lab yuan. Txoj kev npaj no hais txog kev ceev cov kev tshawb fawb thiab kev loj hlob ntawm siab -kev ua tau zoo tshiab sib cais daim nyias nyias, txhawb ntsuab thiab qis- cov txheej txheem carbon pretreatment, thiab ua kom lub domestic hloov pauv ntawm cov ntaub ntawv tseem ceeb, tso tawm ib tug meej txoj cai teeb liab rau kev siv ntawm inorganic ceramic membrane technology. Raws li ntau tshaj kaum xyoo ntawm kev tshawb fawb thiab kev txhim kho kev paub nrog silicon carbide daim nyias nyias, Jianmo Technology's silicon carbide ceramic ultrafiltration membrane luv- txheej txheem pretreatment technology tau ua haujlwm ruaj khov hauv cov dej hiav txwv dej hiav txwv desalination tau ntau xyoo. Tiag -cov ntaub ntawv tshawb fawb thoob ntiaj teb qhia tau hais tias lub zog tseem ceeb ntawm cov khoom siv hauv tsev tsim silicon carbide hauv kev hloov mus rau txhua qhov dej hiav txwv desalination scenarios. Niaj hnub no, sib txuas cov kev taw qhia txoj cai thiab kev siv cov dej num, peb yuav txhais li cas silicon carbide membranes daws qhov mob cov ntsiab lus ntawm ib txwm seawater pretreatment.
I. Nrog rau kev siv lub teb chaws saum toj kawg nkaus - theem kev npaj, seawater desalination yog nkag mus rau lub sij hawm ntawm kev nthuav dav.
Lub "Action Plan for the Development of the Seawater Desalination Industry" qhia txog xya lub luag haujlwm tseem ceeb los qhib kev lag luam kev loj hlob muaj peev xwm:
1. Kev nthuav dav dej hauv nroog: loj- cov phiaj xwm desalination rau ob qho tib si ib txwm siv thiab siv thaum muaj xwm txheej ceev yuav tsim nyob rau hauv ntug dej hiav txwv megacities thiab super- lub nroog loj los tiv thaiv cov dej ntsev nkag thiab dej tsis txaus. Cov dej desalinated yuav muab tso rau hauv kev sib koom ua ke ntawm kev faib dej hauv nroog, ntxiv 1.3 lab tons / hnub ntawm kev tsim khoom hauv nroog.
2. Tag nrho cov kev pab cuam ntawm ntug dej hiav txwv Islands tuaj: Cov Islands tuaj tseem ceeb tau nruab nrog cov chaw desalination nrog lub peev xwm ntawm 1,000 tons, thiab cov khoom siv hauv tsev tsim desalination tau teeb tsa rau hauv dej hiav txwv - mus nuv ntses cov nkoj thiab cov ntug dej hiav txwv, tsis tu ncua tso cov kev xav tau ntawm cov dej rau tej thaj chaw deb;
3. Yuav tsum tau txhawb nqa kev siv dej hauv kev lag luam: ntug dej hiav txwv petrochemical, thermal zog, nuclear fais fab thiab lwm yam dej siab -kev siv cov chaw ua lag luam yuav tsum muab qhov tseem ceeb rau kev siv cov dej hiav txwv desalinated, nruj me ntsis tswj kev tso tawm cov dej tawm tshiab, thiab qhov kev thov rau kev lag luam kev lag luam desalination yog qhov muaj zog tshaj.
4. Kev tsim khoom hauv tsev ntawm cov ntaub ntawv membrane tau teev tseg raws li txoj haujlwm tseem ceeb: Txoj cai tshwj xeeb hu rau kev ua haujlwm siab ntawm -kev ua tau zoo ultrafiltration, nanofiltration, thiab cov ntaub ntawv sib cais tshiab, txhim kho cov cim tseem ceeb xws li tiv thaiv - fouling, lub neej ntev, thiab kev ua haujlwm siab, thiab ua kom muaj kev hloov pauv ntawm ib qho ntawm cov khoom xa tuaj; Nyob rau tib lub sijhawm, nws txhawb kev siv cov txheej txheem ntsuab pretreatment, concentrated brine resource kev siv, thiab lub zog huv si ua ke nrog desalination tej yaam num, thiab tshem tawm cov khoom siv kho mob outdated nrog kev siv tshuaj lom neeg thiab cov txheej txheem ntev.
Kev lag luam kwv yees hais tias ntxiv tsuas yog 1.5 lab tons / hnub ntawm desalination peev yuav xav tau kev lag luam engineering ntawm 22.5-37.5 billion yuan. Raws li cov tub ntxhais pretreatment chav tsev ntawm RO system, pretreatment yog muaj kev xav tau ntawm kev lag luam, thiab cov ntaub ntawv membrane tshiab uas tiv taus cov ntsev siab, kev cuam tshuam, thiab kev saib xyuas qis tau nkag mus rau lub qhov rais kub ntawm lub sijhawm.
II.Cov txheej txheem kev kho dej hiav txwv ib txwm qhia txog lawv cov kev txwv, thaum silicon carbideceramic membraneluv-cov txheej txheem kev daws teeb meem muaj cov kev daws teeb meem.
Ob qhov kev sib tw tseem ceeb ntawm cov tsoos craftsmanship:
Multi-theem coagulation sedimentation + xuab zeb filtration txheej txheem yog ntev, yuav tsum muaj ib tug loj cheeb tsam, muaj cov tshuaj ntau npaum li cas, tsim ib tug ntau ntawm sludge, thiab cov effluent yog nquag tshaj tus txheej txheem thaum lub sij hawm liab tide thiab tidal siab turbidity lub sij hawm, ua rau lub downstream RO membrane.
PVDF organic membranes tsis tiv taus cov ntsiab lus ntsev thiab muaj zog oxidative tu hauv dej hiav txwv, thiab yuav tsum tau hloov tag nrho txhua 1-3 xyoos, ua rau cov nqi tu mus sij hawm ntev.
Qhov zoo ntawm kev sivJMFILTECsiliconcarbide ceramic membrane:
Nws tiv taus cov ntsev siab thiab muaj zog acid thiab alkali, thiab tuaj yeem rov qab ntxuav nrog cov tshuaj tsis o lossis puas tsuaj; nws yog natively hydrophilic nrog high throughput, resists irreversible algal colloidal kuab paug, thiab ho ncua lub voj voog tu;
Cov txheej txheem sintering ua ke ua rau muaj zog txhua yam, tsis muaj kev cuam tshuam los ntawm kev hloov pauv ntawm cov dej tuaj, ua kom cov dej ruaj khov, thiab muab kev tiv thaiv ntev ntev.
Cov txheej txheem luv luv tshem tawm ntau theem pom, txo cov hneev taw los ntawm 60%, muaj qib siab ntawm automation, thiab txo qis kev siv tshuaj thiab cov khoom pov tseg.
kev pab cuam lub neej, 3-5 npaug ntawm cov organic membranes, thiab txo nqi tag nrho.
III. Ntev -lub sij hawmntawm - qhov kev tshawb xyuas qhov project ua haujlwm kom paub meej tias kev loj hlob thiab kev ntseeg tau ntawm silicon carbidedaim nyias nyiass.
Saib xyuasntawmyav dhau lostej yaam num:
Cov dej hiav txwv desalination project rau aquaculture raws tus ntug dej hiav txwv Zhejiang siv ze ntawm ntug dej hiav txwv tidal seawater raws li cov dej nyoos. Kev cuam tshuam los ntawm lub caij nyoog thiab cov dej ntws, cov turbidity, algae, thiab cov ntsiab lus colloid ntawm cov dej hloov pauv tau zoo heev. Tag nrho cov txheej txheem pretreatment txais yuav luv luv - txheej txheem silicon carbide tiaj tus- daim ntawv membrane tshuab thiab tau tsim thiab muab tso rau hauv ob theem.
Thawj theem ntawm txoj haujlwm tau ua haujlwm ruaj khov rau plaub lub xyoos yam tsis muaj teeb meem xws li daim nyias nyias tawg lossis cov dej ntws mus tas li. Qhov thib ob txoj haujlwm nthuav dav tau muab tso rau hauv kev ua haujlwm ib txhij, tsis tu ncua thiab ruaj khov ua cov dej ua ntej uas ua tau raws li RO pub dej cov qauv.
Lub phiaj xwm tau coj cov kev txhim kho kom pom tseeb: tus nqi ntawm cov reagents ntxiv tau txo qis, thiab tus nqi ntawm cov sludge pov tseg tau qis dua; Qhov zaus ntawm kev ntxuav lub rov qab osmosis membrane tau raug halved, txuas lub neej kev pab cuam ntawm lub rov qab osmosis membrane; cov nqi tu txhua xyoo ntawm tag nrho cov kab ke tau raug txo kom tsawg; kev ntseeg siab ntawm silicon carbide daim nyias nyias nyob rau hauv qhov kev hloov pauv ntawm cov dej nyob ze ntawm ntug dej tau raug tshawb xyuas tag nrho; thiab cov txheej txheem kev daws teeb meem tuaj yeem ncaj qha replicated thiab txhawb nqa.

Qhov loj -scale, tsim nyob rau hauv domestic, thiab ntsuab kev loj hlob ntawm seawater desalination tau dhau los ua ib tug irreversible qauv nyob rau hauv kev lag luam. Cov kev txwv kev ua haujlwm ntawm ib txwm ntev- cov txheej txheem thev naus laus zis thiab cov organic ultrafiltration membranes tsis tuaj yeem ua tau raws li qhov ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov haujlwm tshiab thiab hloov kho dua tshiab. Luv- txheej txheem txheej txheem pretreatment technology nrog silicon carbide ceramic membranes ntawm nws cov tub ntxhais tau dhau los ua cov kev daws teeb meem zoo tshaj plaws rau kev kho dua tshiab, rov tsim kho dua tshiab, thiab tsim cov dej hiav txwv tshiab desalination vim nws ntau yam zoo, suav nrog kev tiv thaiv corrosion, siab dhau, kev ua neej ntev, thiab kev cog lus me me.
1. Rau kev nug txog cov txheej txheem xaiv rau ntug hiav txwv dej hiav txwv desalination pretreatment tej yaam num thiab luv- txheej txheem kev daws teeb meem siv silicon carbide daim nyias nyias, thov xa ib tsab xov xwm.
2. Cov kws tshaj lij kev lag luam tshwj xeeb hauv cov txheej txheem engineering thiab kev ua haujlwm thiab kev saib xyuas yog txais tos los qhia lawv cov ntsiab lus mob thiab kev paub txog kev ua haujlwm ntawm seawater pretreatment hauv nqe lus, thiab kawm los ntawm ib leeg.
