Phau Ntawv Qhia Txog Kev Kho Cov Nqi Them Nqi (USD-Raws li Kev Ntsuam Xyuas)
🔷 Kev Taw Qhia
Nyob rau hauv industrial dej kho, eg. hauvceramic wastewater kho cov nroj tsuag, ntau tus neeg yuav khoom sib pivPolyaluminium Chloride (PAC)tsuas yog los ntawm:
28% Al₂O₃ cov ntsiab lus
Nqe ib tuj
Txawm li cas los xij, txoj hauv kev no feem ntau ua rauzais cov nqi ua haujlwm, nrog rau kev siv tshuaj lom neeg ntau dua thiab cov nqi pov tseg sludge.
Qhov sib txawv ntawm kev ua tau zoo yog txiav txim los ntawmPAC lub hauv paus, tsis tsuas yog Al₂O₃ cov ntsiab lus.
🔷 PAC Basicity yog dab tsi?
Basicity yog hais txog qib ntawm pre-hydrolysis hauv PAC, sawv cev rau qhov piv ntawm hydroxyl pawg (OH⁻) rau txhuas ions (Al³⁺).
Basicity (%)=[OH] / (3 × [Al]) × 100
Nws ncaj qha cuam tshuam:
Aluminium hom kev faib tawm
Coagulation mechanism
Floc tsim efficiency
Yuav tsum tau noj ntau npaum li cas hauv kev kho dej khib nyiab
🔷 Ob Hom 28% PAC hauv Kev Ua Lag Luam
🦹 PAC qis (40-60%)
Tsawg dua qib polymerization
Cov ntsiab lus Al³⁺ siab dua
Slower floc tsim
Ntau dua nyob rau hauv -dej hydrolysis
High Basicity PAC (70–85%)
High pre-polymerized qauv (Al₁₃ dominant)
Faster charge neutralization
Muaj zog particle bridging
Ntau ruaj khov nyob rau hauv cov dej sib txawv
🔷 Ceramic Wastewater Application Scenario
Ceramic nroj tsuag feem ntau tsim cov dej khib nyiab nrog:
High suspended solids
Av nplaum hais
Pigments thiab xim compounds
Fluctuating turbidity (100-1500 NTU)
Qhov no ua rau coagulation efficiency siab heev rau PAC qauv.
🔷 Dosage Comparison (Industrial Reality Model)
| Parameter | Tsawg Basicity PAC | High Basicity PAC |
|---|---|---|
| Kev noj tshuaj | 130-160 mg / L | 80-110 mg / L |
| Nruab nrab siv | 140 mg/l | 95 mg/l |

🔷 Tus nqi sib piv (USD ib m³ dej khib nyiab)
Kev xav:
PAC tus nqi ntau:$180 - $220 / ton
🦏 Tsawg Basicity PAC
0.14 kg × $180/ton
= $0.0252 ib m³ dej khib nyiab
🩸 High Basicity PAC
0.095 kg × $200 / tuj
= $0.0190 ib m³ dej khib nyiab
📉 Qhov Xeem Kawg
👉 18-25% txo tag nrho cov nqi tshuaj ib m³ dej khib nyiab
🔷 Hidden Operational Nqi txo
Lub hauv paus tseem ceeb PAC kuj txo:
🟠 Sludge Volume
10-25% txo
Cov txiaj ntsig ua haujlwm
Txo cov nqi pov tseg sludge
Txo lim clogging
Ntau ruaj khov cog kev lag luam
Yuav tsum tau siv tshuaj tsawg dua
🔷 Yog vim li cas Basicity tseem ceeb tshaj tus nqi
Feem ntau qhov kev txiav txim yuav khoom yog tsom rau:
❌ Nqe ib tuj
❌ Al₂O₃ cov ntsiab lus
Tab sis tus nqi engineering tiag tiag yog:
✔ Nqi ib cubic meter ntawm cov dej khib nyiab kho (USD/m³)
Vim:
Dosage txiav txim tag nrho cov tshuaj noj
Sludge txiav txim tus nqi pov tseg
Stability txiav txim siab ua hauj lwm efficiency
🔷 Pom zoo daim ntawv thov
High yooj yim PAC (70-85%) yog qhov zoo tagnrho rau:
Ceramic wastewater kho cov nroj tsuag
Mining dej khib nyiab systems
Industrial effluent nrog siab fluctuation
Tsawg kub lossis dej tsis ruaj khov
🔷 Daim Ntawv Pom Zoo Txiav Txim Siab
Txhawm rau txheeb xyuas qhov kev ua tau zoo ntawm cov nroj tsuag tiag tiag:
Ntim: 5-10 tons mus sib xa khoom
Txoj kev: sab-los ntawm- sab kev sib piv
KPIs:
Turbidity tshem tawm efficiency
Teeb meem ceev
Sludge ntim
Tshuaj noj ib m³
🔥 FAQ (SEO Optimized)
❓ Dab tsi yog qhov txawv ntawm qhov siab thiab qis PAC?
Lub hauv paus tseem ceeb PAC muaj ntau dua ua ntej-polymerized aluminium hom, ua rau cov coagulation sai dua, qis dua, thiab txo cov sludge piv rau PAC qis.
❓ Puas yog qhov pib siab dua ib txwm txhais tau tias ua tau zoo dua?
In most industrial wastewater applications, yes. However, extremely high basicity (>85%) tuaj yeem txo qhov ruaj khov.
❓ Vim li cas PAC ntau npaum li cas sib txawv rau tib 28% Al₂O₃?
Vim tias coagulation efficiency nyob ntawm cov qauv polymer thiab txhuas hom kev faib tawm, tsis yog tsuas yog concentration.
❓ IbPACpuas zoo dua rau kev kho dej khib nyiab ceramic?
Lub hauv paus tseem ceeb PAC (70-85%) ua tau zoo dua vim yog kev tsim floc sai thiab muaj zog tiv thaiv cov dej tsis zoo.
