Yuav kho cov dej khib nyiab li cas: Cov nyom tseem ceeb thiab kev daws teeb meem
1. Kev sib xyaw ua ke
Muaj ntau yam organic thiab inorganic, xws li cov tshuaj tsw qab thiab cov hlau hnyav.
2. Muaj toxicity
Feem ntau muaj cov tshuaj lom thiab muaj kev phom sij, ua rau muaj kev phom sij loj rau cov kab mob nyob.
3. Wide pH Variability
Tej zaum yuav muaj zog acidic los yog alkaline; muaj ntau cov khoom refractory uas nyuaj rau degrade los ntawm cov qauv siv.
4. High Salinity
Qee cov dej khib nyiab muaj ntsev ntau.

Txoj kev kho mob
Txoj Kev 1: Cov Txheej Txheem Kev Kho Kom Zoo
- Kev Kho Mob Tseem Ceeb
Feem ntau tshem tawm cov khib nyiab, cov khoom colloidal, cov roj ntab, lossis cov roj hnyav. Cov txheej txheem muaj xws li kev khiav thiab thauj khoom sib npaug, ntuj tsim, flotation, thiab roj sib cais.
- Kev Kho Mob Thib Ob
Feem ntau tsom rau biodegradable organic yaj tshuaj thiab qee qhov teeb meem colloidal, txo qis biochemical oxygen xav tau (BOD) thiab ib feem ntawm cov tshuaj oxygen xav tau (COD). Cov kev kho mob lom neeg feem ntau yog siv. Tom qab kev kho mob thib ob, COD seem yuav nyob twj ywm, nrog rau cov xim muaj peev xwm, tsw ntxhiab, lossis teeb meem saj. Yog tias siv cov qauv nruj dua ib puag ncig, yuav tsum tau kho tertiary.
- Kev Kho Mob Thib Ob
Tsom ntsoov rau tshem tawm cov uas tsis yog - biodegradable organic pollutants thiab soluble inorganic pollutants. Cov txheej txheem muaj xws li activated carbon adsorption, ozone oxidation, ion exchange, thiab membrane sib cais technologies.
Txoj Kev 2: Advanced Treatment Technologies
- Kev kho mob
- Advanced Oxidation: Fenton reagent (H₂O₂/Fe²⁺) rau refractory COD tshem tawm (40-70% efficiency).
- Electrocatalytic Oxidation: BDD electrode rau cyanide- muaj kev kho dej khib nyiab (tam sim no efficiency txog li 85%).
- Kev kho mob lom
- Cov txheej txheem Anaerobic: IC reactor nrog COD loading peev ntawm 15-30 kgCOD/(m³·d).
- Aerobic txheej txheem: MBBR biofilm txoj kev nrog sludge concentration ntawm 8-12 g / L.
- Kev kho mob siab heev
- Catalytic Ozonation (TiO₂/UV system): TOC removal >60%.
- Reverse Osmosis (fouling-resistant membranes): Recovery rate >70%.
