Taw qhia: Vim li cas Dej Zoo Txiav Txim Aquaculture Success
Aquaculture tau dhau los ua ib qho sai tshaj plaws - kev loj hlob ntawm cov khoom noj khoom haus thoob ntiaj teb, tab sis nws tseem muaj kev cuam tshuam rau cov dej zoo. Kev sib sau ntawm ammonia, nitrite, thiab organic pov tseg tuaj yeem ua rau muaj kab mob tshwm sim, kev ntxhov siab, txo qis kev loj hlob, thiab cov khoom poob. Raws li cov khoom ntim khoom nce ntxiv thiab cov kev cai tso dej tawm tau nruj dua, kev ua haujlwm ntawm cov thoob dej yug ntses niaj hnub tau nce ntxiv rau kev siv tshuaj lom neeg pom.
Bioblock lim xov xwm, Ameslikas tsim rau kev kho dej khib nyiab siab heev, tau txais kev pom zoo hauv aquaculture vim nws qhov chaw siab, kev ruaj ntseg, thiab kev pab lub neej ntev. Thaum thov kom raug, Bioblock muab cov kev daws teeb meem muaj zog thiab ua kom muaj zog rau kev tswj xyuas cov dej ruaj khov hauv ob qho tib si dej tshiab thiab dej hauv hiav txwv.
Bioblock ua haujlwm li cas hauv Aquaculture Systems
Bioblock yog ib qho khoom siv lim dej ruaj khov uas tsim los ntawm nkauj xwb HDPE, tsim los nrog peb - cov qauv lattice. Thaum muab tso rau hauv biofilter tso tsheb hlau luam los yog yees, nws muab qhov chaw zoo tagnrho rau cov kab mob nitrifying thiab heterotrophic.
Tsis zoo li cov xov xwm raug tshem tawm uas vam khom mus tas li, Bioblock tseem nyob ruaj khov thaum dej ntws los ntawm nws. Qhov no tso cai rau biofilm txhim kho nyob rau hauv ib puag ncig ruaj khov nrog tsawg kawg shear stress. Raws li dej dhau los ntawm kev tshaj tawm, ammonia (NH₃ / NH₄⁺) tawm los ntawm cov ntses yog oxidized rau hauv nitrite (NO₂⁻) thiab tom qab ntawd mus rau hauv nitrate (NO₃⁻), txo qis toxicity theem.
Vim hais tias cov channel sab hauv ntawm Bioblock yog qhov loj thiab zoo- faib tawm, cov pa oxygen hloov mus tau zoo thaum qhov kev pheej hmoo ntawm kev txhaws raug txo qis -ib qho txiaj ntsig tseem ceeb hauv cov kab dej hauv av uas cov khoom thauj tuaj yeem hloov pauv.
Qhov zoo ntawm Bioblock piv nrog cov tsoos Bio Media
Ib qho txiaj ntsig tseem ceeb tshaj plaws ntawm Bioblock yog nws qhov tshwj xeeb ua haujlwm zoo ntawm thaj chaw ua ke nrog lub zog siv tshuab. Ib txwm siv dag siv dag zog los yog random-cov khoom siv bio media tuaj yeem ua rau lub sijhawm luv luv, tawg hauv qab thauj khoom, lossis yuav tsum tau hloov ntau zaus. Hauv qhov sib piv, Bioblock modules tau tsim los txhawb ob qho tib si hydraulic siab thiab tib neeg kev nkag, ua kom yooj yim tshuaj xyuas thiab tu.
Lwm qhov txiaj ntsig tseem ceeb yog nyob rau hauv kev ua haujlwm ruaj khov. Bioblock systems tuaj yeem zam qhov sib txawv ntawm cov nqi ntws thiab kev poob siab, uas muaj ntau thaum lub sij hawm pub mis, sau qoob, lossis kev sib pauv dej ib nrab. Qhov kev ruaj ntseg no pab tswj kev ua tau zoo nitrification zoo ib yam, txawm tias nyob rau hauv kev ua liaj ua teb hnyav.
Los ntawm kev xav txog tus nqi lifecycle, Bioblock's non-degradable HDPE cov ntaub ntawv thiab UV tiv thaiv ua rau kev pab cuam lub neej tshaj 20 xyoo, ua rau nws txaus nyiam rau ntev - aquaculture peev.
Kev siv Bioblock hauv Recirculating Aquaculture Systems (RAS)
Recirculating Aquaculture Systems (RAS) nyob ntawm qhov siab ntawm -kev ua haujlwm biofiltration, vim tias cov dej rov siv dua feem ntau tshaj 90%. Hauv cov kab ke no, Bioblock feem ntau yog ntsia rau hauv cov khoom siv biofilter, hloov lwm lub txaj, lossis ntsug bio-reactor towers.
Vim Bioblock tsis tas yuav txav mus tas li, kev siv hluav taws xob txo qis piv rau MBBR ib txwm muaj- qauv tsim. Cov qauv ruaj khov kuj tso cai rau kev tswj xyuas meej ntawm hydraulic tuav lub sij hawm, ua rau ntau qhov kev txiav txim siab nitrogen tshem tawm.
RAS cov neeg ua haujlwm muaj nuj nqis Bioblock tshwj xeeb rau nws qhov tsis tshua muaj kev cuam tshuam thiab yooj yim ntawm kev koom ua ke nrog cov tshuab pom cov tshuab xws li nruas lim thiab cov ntsiab lus meej.
Case Study 1: Freshwater Tilapia Farm in Southeast Asia
Ib lub lag luam tilapia ua liaj ua teb ua haujlwm 1,200 m³ RAS qhov chaw tau ntsib cov kab mob ammonia ntev ntev thaum lub sijhawm pub mis. Tus thawj biofilter muaj cov nplhaib yas nrog thaj tsam ntawm qhov chaw tsawg thiab nquag channeling.
Tom qab retrofitting lub biofilter chamber nrog Bioblock modules, lub kaw lus tau ua tiav ntsuas kev txhim kho nyob rau hauv yim lub lis piam. Tag nrho cov ammonia nitrogen (TAN) qib tau txo qis los ntawm qhov nruab nrab ntawm 1.2 mg / L mus rau qis dua 0.3 mg / L, thaum nitrite concentrations stabilized nyob ze ntawm qhov tsis muaj - qib ntsuas. Cov ntses ciaj sia taus tau nce los ntawm kwv yees li 8%, thiab kev hloov pauv hloov pauv tau pom tias muaj kev txhim kho zoo ib yam.
Kev ua liaj ua teb tau tshaj tawm txo kev tu ntau zaus thiab tsis muaj qhov tseem ceeb biofilter downtime tshaj 18 lub hlis ntawm kev ua haujlwm tas mus li.
Case Study 2: Marine Shrimp Hatchery with High Organic Load
Nyob rau hauv lub marine cw hatchery siv ib nrab dej pauv, organic loading thiab biofouling yog tsis tu ncua. Bioblock media tau teeb tsa nyob rau hauv ntsug biofilter ntauwd downstream ntawm cov protein skimmer.
Qhov loj void piv thiab tus kheej - txhawb nqa qauv ntawm Bioblock tso cai rau biofilm kom vam meej yam tsis muaj cov khib nyiab ntau dhau. Nitrification efficiency
nce los ntawm kwv yees li 30% piv nrog rau yav dhau los packed - txaj xov xwm, thaum lub siab poob thoob plaws biofilter tseem nyob ruaj khov.
Qhov tseem ceeb, qhov chaw yug me nyuam tau pom zoo pH ruaj khov thiab yaj cov pa oxygen, txhawb kev noj qab haus huv ntawm larval thiab kev loj hlob zoo dua.
Kev tsim thiab kev txiav txim siab ua haujlwm
Thaum Bioblock muaj ntau yam, kev tsim qauv tsim nyog yog qhov tseem ceeb. Kev faib tawm ntws yuav tsum tsis sib xws kom tsis txhob muaj qhov chaw tuag, thiab ua ntej - pom zoo kom tiv thaiv cov khib nyiab ntau dhau. Hauv ib puag ncig aquaculture, ua ke Bioblock nrog cov ntxaij lim dej ua kom ntseeg tau ntev - lub sijhawm ua haujlwm thiab txo qis kev siv phau ntawv tu.
Pib- lub sijhawm nce feem ntau yuav tsum tau ua tib zoo saib xyuas, vim tias qhov chaw biofilm nyob ntawm qhov kub thiab txias, salinity, thiab muaj oxygen. Thaum matured, txawm li cas los xij, Bioblock-raws li biofilters ua kom pom kev ua haujlwm siab thiab kev ntseeg siab.
Lub neej yav tom ntej ntawm Bioblock hauv Aquaculture
Raws li kev lag luam aquaculture txav mus rau qhov ceev dua, kev siv dej tsawg dua, thiab kev ua raws li ib puag ncig nruj dua, kev pom kev lom neeg muaj txiaj ntsig yuav tseem yog lub hauv paus ntawm kev tsim qauv. Bioblock xov xwm ua tau zoo nrog cov qauv no los ntawm kev muab kev ua kom muaj zog, ua haujlwm ntev, thiab kev ua haujlwm zoo ib yam.
Nws kev saws me nyuam nyob rau hauv ob qho tib si kev lag luam- nplai ua liaj ua teb thiab cov chaw me me qhia txog kev hloov pauv mus rau cov tshuab biofilm uas muaj peev xwm los txhawb kev loj hlob ntawm aquaculture.
