Ikev taw qhia
Nrog rau cov txheej txheem nruj ib puag ncig thiab kev xav tau nce ntxiv rau cov dej rov qab siv dua, membrane bioreactors (MBRs) tau dhau los ua cov thev naus laus zis thev naus laus zis rau kev kho dej khib nyiab thiab kev siv peev txheej. Membrane cov ntaub ntawv, raws li cov ntsiab lus tseem ceeb ntawm MBRs, ncaj qha txiav txim siab qhov kev ua haujlwm ruaj khov, kev kho mob, thiab tag nrho cov nqi ntawm lub neej. Ib txwm cov organic daim nyias nyias raug kev txom nyem los ntawm cov teeb meem xws li susceptibility rau fouling, luv lifespan, thiab tsis zoo corrosion kuj, ua rau lawv tsis haum rau complex thiab hnyav dej. Silicon carbide flat-cov ntaub ntawv, nrog lawv cov khoom zoo tshaj plaws ntawm ultra- corrosion resistance, siab flux, ntev lifespan, thiab muaj zog los tiv thaiv- fouling muaj peev xwm, muab ib tug robust tov rau MBR txheej txheem upgrade thiab yog dav siv nyob rau hauv lub nroog cov dej khib nyiab, industrial wastewater, thiab concentrated brine kev kho mob.
I. Taw qhia rau MBR Technology
1. Txheej txheem txheej txheem
MBR (Membrane Bioreactor) yog cov txheej txheem kho dej khib nyiab uas sib xyaw ua ke biodegradation thiab membrane sib cais thev naus laus zis. Nws hloov cov theem nrab sedimentation tank nyob rau hauv cov tsoos activated sludge txheej txheem nrog ib tug ultrafiltration membrane module, ua tau zoo sib cais ntawm sludge thiab dej. Tom qab cov dej khib nyiab nkag mus rau hauv bioreactor, cov kab mob me me decompose cov pa phem xws li COD, ammonia nitrogen, thiab tag nrho phosphorus; lub ultrafiltration membrane (pore loj 0.02-0.1μm) precisely ntxiab activated sludge, colloids, kab mob, thiab tshem tawm hais, ua rau kom meej thiab sterile effluent, kiag li daws cov teeb meem ntawm sludge poob thiab turbid effluent nyob rau hauv ib txwm cov txheej txheem.
2. Cov yam ntxwv tseem ceeb ntawm cov txheej txheem
(1) Muaj peev xwm kho tau zoo thiab zoo effluent zoo
Cov txheej txheem MBR muaj kev thauj khoom siab thiab kev kho mob ntau dua li kev kho cov tshuaj lom neeg. Cov dej ntws zoo zoo ib yam li cov kais dej hauv qhov tsos thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua rau cov dej rov qab. Nws yog tam sim no thev naus laus zis nrog qhov zoo tshaj plaws effluent zoo ntawm tag nrho cov txheej txheem dej khib nyiab.
(2) Muaj zog tiv thaiv kev cuam tshuam kev thauj khoom
Qhov siab sludge concentration muab MBR muaj zog tiv thaiv kev poob siab, thiab nws kuj muaj lub hnub nyoog sludge ntev heev, ua rau muaj kev ruaj ntseg zoo heev.
(3) Zoo ammonia nitrogen tshem tawm cov nyhuv
Nrog siab sludge concentration, ntev sludge hnub nyoog, thiab tsawg sludge load, nws yog tshwj xeeb tshaj yog haum rau nitrification kom tshem tawm ammonia nitrogen, thiab tshem tawm txog li 1500 mg / L ntawm ammonia nitrogen.
(4) Tsawg residual sludge
MBR sludge muaj lub hnub nyoog sludge ntev, cov kab mob nyob rau hauv lub endogenous respiration theem, cov sludge ntau lawm yog tsawg, thiab cov pa phem theem nrab yog tsawg.
(5) Txuag av
Nws tsis tas yuav tsum muaj lub tank thib ob lossis lwm yam khoom siv lim thiab lim dej. Cov txheej txheem yog yooj yim thiab nyob hauv ib cheeb tsam me me, tsuas yog li 1/3 ntawm thaj av uas yuav tsum tau ua los ntawm cov txheej txheem kev kho mob, ua rau nws tsim nyog siv rau hauv cov chaw tsis muaj av.
(3) Tsis siv neeg tswj, yooj yim rau nruab
MBR tshem tawm cov teeb meem ntawm cov sludge bulking thiab sludge poob, ua rau qis qis ntawm cov sludge seem, thiab tuaj yeem ua tiav kev tswj hwm, ua haujlwm thiab kev tswj xyuas yooj yim.
II. Qhov zoo ntawm Silicon Carbide Flat Sheet Membranes hauv MBR txheej txheem
1. Tsis tshua muaj corrosion resistant, haum rau huab cua ua hauj lwm tej yam kev mob
Ua los ntawm siab -purity silicon carbide hmoov recrystallized thiab sintered ntawm 2400 degree, nws yog resistant rau acids thiab alkalis nyob rau hauv lub pH ntau ntawm 0-14, thiab muaj peev xwm tiv taus corrosion los ntawm muaj zog acids, muaj zog alkalis, siab -concentration oxidants thiab organic solvents. Nws tuaj yeem ua haujlwm ruaj khov thiab tsis muaj kev laus nyob rau hauv cov dej hnyav xws li concentrated brine, chemical wastewater thiab landfill leachate rau lub sijhawm ntev.
2. Kev ua haujlwm siab -throughput, uas ua rau kev ua haujlwm ntau dua.
Lub daim nyias nyias muaj lub kaum sab xis ntawm dej tsuas yog 10.3 degree, ua rau nws tsis tshua muaj dej. Nws kev khiav hauj lwm flux yog ruaj khov ntawm 60-100 LMH, uas yog 3-4 npaug ntawm cov organic membranes. Rau tib qhov kev kho mob, nws yuav tsum tau tsawg dua qhov chaw ntawm daim nyias nyias thiab lub membrane tank occupies tsawg qhov chaw, txo cov nqi hluav taws xob engineering.
3. Muaj zog tiv taus stains, yooj yim los ntxuav thiab rov ua dua
Lub membrane nto yog qhov tsis zoo them nqi, electrostatically repelling sludge, colloids, thiab roj, uas ua rau muaj kev tiv thaiv zoo heev - fouling muaj peev xwm. Aeration thiab flushing ncua fouling, thiab tom qab fouling, siab -concentration acid, alkali, thiab oxidant tu yuav rov qab 100% ntawm cov flux. Lub voj voog tu yog ntev thiab kev saib xyuas yooj yim.
4. Ultra-ntev lifespan thiab qis tag nrho cov nqi lifespan.
Nws muaj lub zog txhua yam, hnav tsis kam, tsis muaj kev pheej hmoo ntawm fiber ntau tawg, thiab kev pabcuam lub neej ntau dua lossis sib npaug li 10 xyoo, uas yog 3-4 npaug ntawm cov organic membranes; lub aeration ntim tsuas yog ib nrab ntawm cov organic membranes, uas ua rau tsis muaj zog noj; nws tsis tas yuav hloov daim nyias nyias, txo cov nqi siv tau thiab lub sijhawm poob qis, thiab muaj txiaj ntsig zoo rau kev lag luam thoob plaws nws lub neej tag nrho.
5. Zoo tshaj thiab yooj yim rau kev txhim kho thiab hloov kho.
Nws yog tag nrho sib xws nrog cov organic MBR uas twb muaj lawm thiab tuaj yeem hloov cov organic membranes hauv qhov chaw yam tsis muaj kev hloov kho khoom loj; nws yog tsim rau complex dej zoo xws li siab sludge concentration, siab roj cov ntsiab lus, thiab siab salinity, thiab yog ib qho yooj yim rau upgrade thiab ceev qhia tau.
