2. Cov txheej txheem pheej hmoo pheej hmoo
A. Lub Sij Hawm Ua Haujlwm Tsis Txaus
•Bar screen inefficiency: >5 hli particle bypass correlates nrog 35% TSS kev ua txhaum
• Cov kab mob luv luv-qhia hauv cov lus qhia luv luv: 15 degree ΔT nruab nrab ntawm cov neeg tuaj yeem cuam tshuam / effluent triggers aya audits
B. Kev kho mob biological
• Mlvss / MLSS piv<0.7 indicates poor biomass activity
•DO fluctuations >{0. 5 mg / l txo cov nqi nitrification 40%

•Membrane fouling indices >3. {{0 (sdi15) tas yuav tsum muaj kev cuam tshuam
• chlorine hu lub sijhawm<30 minutes fails CT requirements for pathogen kill
3. Ntse ua txhaum cov cuab yeej
| Tej txuj ci tshiab | Rooj mov | Kev ua raws cai |
|---|---|---|
| Tiag tiag-lub sij hawm LC-MS / MS | Nruam kev saib xyuas ntawm 120+ cwa volutants | 90% kev kuaj mob sai sai |
| Ai-powered Scada | Kev kwv yees ua qauv ntawm effluent tiam sis | Txo SNC cov xwm txheej los ntawm 65% |
| Kev Tshaj Tawm | Immutable txo cov ntaub ntawv nkag mus | 100% kev kuaj xyuas txoj kev ua raws cai |
4. Cov kev ua raws cai ua raws cai
A. Ua haujlwm rau kev sib tw
• Ntawv pov thawj: Abc Wastewater qeb IV + cov neeg ua haujlwm
• Kev muaj tiag veracult (VR) rau kev teb cov lus teb
B. Cov tswv yim sib xyaw ua ke
• Mabr retrofits ua tiav 8 mg / u ua nrog 40% tsawg zog
•Electrocoagulation systems remove 99% heavy metals @ 0.8 kWh/m³
C. Nyiaj txiag tsim nyiaj
