Qhov $ 1.2M txhua xyoo poob: Vim li cas cov diffusers tsis ua tiav
Kev siv dej kom qhuav los ntawm cov roj ua kom huv thiab khoom noj muaj:
- Cov roj roj pub dawb({50-200 μm) ua raws li membrane pores
- Siab TSS (>800 mg \/ l) los ntawm cov khoom seem
- Calcium carbonate scaling (CaCO3 >500 mg \/ l)
Cov xwm txheej no ua rau 83% ntawm diffuser ua tsis tau nyob hauv 6 lub hlis. Juntai cov kev tshawb fawb teb qhia txog peb-pab daws teeb meem:
Theem 1: Cov Khoom Siv Hauv Hauv paus
| Clogging Hom | Kev ua hauj lwm | Yam Tseem Ceeb |
|---|---|---|
| Organic Fouling | Kev Ua Noj | Lipids polymerize ntawm 35-50 degree |
| Inorganic scaling | Petrochemical | CaCO3 precipitation at pH >8.2 |
| Txoj kev loj hlob biofilm | Chaw ua tshuaj paus | EPS Kev zais cia los ntawm thermophiles |
Kev Kawm Txog: Guangdong Lub Taubube Roj Cog
- Tsab: 80% diffusers txhaws txhua hli
- Hauv paus ua rau: Roj emulsification (150 mg \/ l) + caco3 scaling
- Juntai kev daws teeb meem:
Ib Leeg CivalCalf Av(roj tshem tawm rau<20 mg/L)
Acid Dosing(Ph tswj ntawm 7. 2-7. 5)
Nano-coated diffusers (contact angle >150 Qeb)
- Qho kawg: {9- lub hlis ua haujlwm
Theem 2: Anti-Clogging Khoom Siv Kev Txhim Kho
1. Graphene-txhim kho epdm membranes
- Kab laum: {0. {{05-0. 1mm laser-draged nrog staggered txheej
- Ua yeeb yam:
Roj repellency: 98% (VS tus qauv EPDM 65%)
Scalering Kuj: 85% CaCo3 Txo
2. Dynamic Backflush system
- Kev phais: 15s mem tes txhua 2H ntawm 3 bar
- Kev ua tau zoo:
92% biofilm detach
Zog siv: {{0. 08 kwh \/ m³
3. Iot-enabled soj ntsuam
- Sensors: Plawg siab (Δp<0.3 bar)
- Kev ceeb toom kwv yees: Clogging Pheej Hmoo 72H ua ntej
Sij Hawm 3: Kho Mob Thaum Muaj Xwm Ceev Ceev
| Mus ib ruam taw | Kev ua zog | Kev tsis muaj |
|---|---|---|
| 1 | Tshuaj Soak | 5% citric acid + 0. 5% surfactant (60 degree, 4h) |
| 2 | Kev Tu Tshuab Ultrasonic | 40kHz, 120W \/ CMO (30min) |
| 3 | Neeg Kho Tshuab Scraping | PTFE-coated hniav (tsawg dua los yog sib npaug rau 0. 1 hli residue) |
Tus nqi sib piv:
| Txojkev | Tus nqi \/ kev tshwm sim ($) | Rov qab tus nqi |
|---|---|---|
| Coj kev cai qub | 2,500 | 60% |
| Juntai raws tu qauv | 1,800 | 95% |
