Nruas Lim
Hauv hyper-intensive recirculating aquaculture tshuab (Ras), kev sib ntaus sib tua rau cov dej huv los ntawm micron qib. Nruas teb cov ntxaij lim tawm tawm ua thawj kab ntawm kev tiv thaiv tawm tsam qhov uas muaj kev hem thawj. Nov yog vim li cas cov ntawv xa tawm no yog qhov tsis tseem ceeb:
1. Qhov uas pom muaj kev ua tsov ua rog
• Cov yeeb ncuab cov tub rog:
• Pub khib nyiab (200-800 μm)
• Nkawv Pellets (100-500 μm)
• Bioflolcation (50-300 μm)
• Kev ua kom sib xyaw:
• 1g TSS Siv 2.5g O₂ Txhua Hnub Ntawm Heterotrophs
• 40% nitrification inhibition at TSS >50mg / l
2. Nruag Lim Mechanics Decoded
Tub Ntxhais Kev Txhawb:
• 3D Npoo Hlau Screen(316l SS, 20-100} μm slots)
• Kev tu tus kheej hydraulic({0. {5-1. 5 bar tshuaj tsuag @ 15l / m²)
• Haum RPM tswj({0. {5-3 rpm ntawm turbidity regack)
Txheej Txheem Flow:
1. Axial ntws tawm hauv siab: {0. {3-0. 7m / s
2. Ncuav mog qab zib tsim raws qib: 150PA plawg siab
3. {{{12-} Tsis Muaj Array tshem tawm 98% cov khib nyiab khaws
3. Ras-tshwj xeeb tsim yeej
| Cav | Nruas Lim Kev Kho |
|---|---|
| Oily pub cov seem | PTFE-coated cov ntxaij vab tshaus (hu rau kaum nrab ntawm 110 degree) |
| Biofilm shedding | UV-C Continated Backwash (5s tawg) |
| Kev Tiv Thaiv Kev Tiv Thaiv Larval | 500μm kev nyab xeeb mesh txheej txheej |
4. Kev ua txuj ci
• Kev thauj khoom hydraulic: {50-100 m³ / m² / hnub
• TSS tshem tawm: 85-95% @ 100-500μm
• Kev noj haus zog: {{{{{0}}}}}. 1500 / m³ vs 0.8 hauv cov lim ntoo
Kev Kawm Txog:
Norwegian Salmon ua liaj ua teb tiav:
22% txo qis nyob rau hauv biofilter xov xwm hloov
{{0 {}}. 3mg / l ammonia kev saib xyuas
18% txo tus nqi aeration
Yav tom ntej-pem hauv ntej nta
• Ai Clog twv ua ntej: Kev co sensors + ml algorithms
• Modular pawg: Cov chav ntsug kov 500m³ / h hauv 5m²
• salmon-nyab xeeb tsim: Cov npoo sib npaug los tiv thaiv cov kev puas tsuaj sib npaug
