Recirculating aquaculture pab txhim kho qhov kuab paug ntawm aquaculture
Nyob rau hauv loj-teev aquaculture, cov hlua dej zoo yog qhov tseem ceeb ntawm cov khoom noj uas tseem ceeb, nqus dej los ntawm kev pub noj, thiab cov khib nyiab metabolic. Li no, dej kho lub luag haujlwm tseem ceeb. Siv kev ua kom zoo nkauj ua haujlwm tiv thaiv aquarculture (RAS) muaj ntau yam zoo, feem ntau los ntawm kev muab cov kev tswj hwm ib puag ncig kev tswj hwm ntau. Qhov no ua kom muaj kev txaus siab ib puag ncig rau kev loj hlob nyob rau hauv cov kev nyob ruaj khov.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm Ras cov chaw nyob hauv lawv lub cev kev thaiv thiab tswj cov ntses thiab cws los ntawm kab mob sab nraud. Txawm li cas los xij, cov kab mob pathogenic microorganisms tuaj yeem kis tau los ntawm ntau yam kev nyob hauv ib ncig ua liaj ua teb. Nyob rau hauv cov mob hnyav, lawv tuaj yeem nthuav tawm sai, ua rau muaj kab mob kis tau rau cov neeg ua liaj ua teb.
MBRB med, xws li K1 MBR, ua lub luag haujlwm tseem ceeb hauv Ras. MBBR, lossis txav mus rau lub txaj biofilm reactor, yog kev txhim kho microbial thiab cov organic pov tseg kev ua rau muaj kev cuam tshuam ntau rau cov neeg nqa khoom tshwj xeeb. Cov kab ke no tsis tsuas zoo tshem cov pov tseg tab sis kuj muaj kev tiv thaiv biological zoo siab, mitigating kis tus kis ntawm pathogens. Yog li no, sib xyaw ua ke K1 MBBR thev naus laus zis ua Ras txhim kho tsiaj thiab txhim kho Aquaculture Equacultiency.

Yas MBBL BIO CARIAN MOOT Media Bio Chips Nroj Tsuag Tsis Yooj Yim Thiab Thiaj Ua Haujlwm. Tsis tas li ntawd, kev siv MBRB media tau txo qis cov hneev taw feem ntau. Cov kev daws teeb meem dej tshwj xeeb hauv kev muab cov dej ua lag luam tshiab thiab cov khoom siv khiav tawm thiab kev kho kom zoo nkauj thiab kev siv tshuab. Nrog ntau tshaj li 400 cov nroj tsuag hauv kev ua haujlwm thoob ntiaj teb, peb muab lub koob npe nrov rau kev xa khoom txhim khu kev qha, cov kev daws teeb meem dej kom zoo thiab dej kom dej kom zoo. Cov kev daws teeb meem dej tshwj xeeb hauv kev muab cov dej ua lag luam tshiab thiab cov khoom siv khiav tawm thiab kev kho kom zoo nkauj thiab kev siv tshuab. Nrog ntau tshaj li 400 cov nroj tsuag hauv kev ua haujlwm thoob plaws ntiaj teb, peb muab lub koob npe nrov rau kev txhim khu kev txhim kho Biofility (MBL) yog qhov chaw ua haujlwm biofility) MBRBR muaj cov hlab reactor nrog cov cab kuj muaj cov cab kuj. Biota yuav costize rau saum npoo thiab sab hauv xov xwm, thaum muaj kev sib xyaw ua ke, thaum rov kho tus kheej-ntxuav los ntawm kev tshem tawm ib txwm thiab tsis muaj txiaj ntsig microbes.
MBBRS tuaj yeem siv ua cov ntawv thov anerobic lossis anaerobic. Aerobic MBRS muaj feem ntau hauv kev dav dav, thiab muaj txiaj ntsig zoo tshaj plaws rau thoob dej yug ntses lossis pas dej. Los ntawm kev siv chav me me no, Kuv muaj peev xwm txo qis cov ammonia concentration thiab qeeb lub tsim ntawm algae hauv lub system. Los ntawm cov tshuaj chemical kev pom zoo, ob peb yam tshwm sim:
- Ua rau Nitrification kom hloov ammonia thiab nitrogen hauv cov organic sib txuas rau nitrates
- Txo cov pa oxygen thov (BOD) & tshuaj xav tau pa oxygen (COD)
Cov khoom kom zoo dua:
Thaj Chaw Yam Tsawg Yuav Tsum Tau
Tsawg phau ntawv kev cuam tshuam
Tus nqi nominal
Yooj yim los daws thiab yooj yim rau kev ruaj khov
Yam tsawg kawg nkaus sludge ntau lawm
Txo Sludge Ntau Lawm
High efficiency thiab kev ua tau zoo
BOD thiab COD txo kom txuas ntxiv
Aquatust MBBR:
Yas MBBL BIO CARIRY Media Bio Chips cov kws tshaj lij no tau ua tiav los ntawm peb cov kws tshaj lij siv cov khoom siv raw thiab hloov kho tshuab. Ntxiv mus, qhov ntau tau muab los ntawm peb tau tsim muaj nyob rau hauv ntau qhov kev qhia tshwj xeeb. Ntxiv rau qhov no, cov no yog qhov xav tau los ntawm peb cov neeg siv khoom rau lawv cov neeg yuav khoom thiab kev xav tau ntawm peb cov neeg siv khoom, peb tau muab tus nqi zoo ntawm cov xim PVC granules. Cov khoom no yog qhov tseem ceeb ntawm kev ua tau zoo thiab ntau yam uas muaj rau lawv qhov xwm txheej nquag. Peb cov khoom muaj txiaj ntsig tau ncav cuag hauv ntau yam kev xaiv kev lag luam raws li cov kev xav tau ntawm cov neeg siv khoom.
Qhov Zoo Ntawm Mbbr Cov Khoom & Qauv
(1) Siv cov ntaub ntawv zoo copolymer zoo, xau rau hauv dej khib nyiab ntev yuav tsis muaj tshuaj lom, thiab yuav tsis muaj kuab heev, uas yog qhov zoo dua li lwm cov ntaub ntawv xws li polyvinyl chloride.
(2). Cov qauv tshwj xeeb. Hollow cov qauv ntim muaj peb txheej ntawm cov voj voos hollow sab hauv thiab sab nraud. Txhua lub voj voog muaj 1 ntug hauv thiab 36 npoo sab nraud. Nws tau ua tiav kev tshawb fawb thiab tsim kho tau ntau zaus, thiab nws yog tsim nyob rau ib zaug.
(3). Thaj chaw tshwj xeeb thaj chaw, thaj tsam tshwj xeeb ntawm cov kab mob sib xws tuaj yeem ncav cuag 600, thiab ob chav tshwj xeeb yog qhov siab li {}} lossis ntau dua. Vim yog thaj chaw siab tshwj xeeb, cov biomass ib chav ntim muaj siab, uas tuaj yeem ncav cuag lub hom phiaj ntawm kev tuav haujlwm hydraulic yog luv.
(4). Kev ua haujlwm siab ntawm cov kab mob me me. Lub microbial zaj duab xis loj hlob ntawm cov npoo ntawm cov muab tub lim rau kev sib tsoo vim yog cov fluiding ntawm cov muab tub lim. Aeration thiab scouring ua rau cov kab mob me me hauv lub sijhawm kev loj hlob logarithmic ntawm cov kev ua haujlwm siab thiab cov kev kho kom haum.
(5). Hollow pack yog ntawm cov hom ntab, yooj yim los hloov lub neej thiab ntev kev pabcuam.
(6). Muaj peev xwm muaj peev xwm ntawm kev tsis pom zoo thiab kev rhuav tshem cov teeb meem organic, ua tiav lub hom phiaj ntawm kev tshem tawm ammonia nitrogen.
