Kev ua haujlwm thiab kev siv ntawm sodium acetate hauv kev kho dej khib nyiab

Kev ua haujlwm thiab kev siv ntawm sodium acetate hauv kev kho dej khib nyiab,
Ua kua Sodium Acetate, kua sodium acetate cuam tshuam, Ua kua sodium acetate manufacturers, kua sodium acetate siv, Sodium acetate manufacturers,
1. Cov cim tseem ceeb:
Cov ntsiab lus: ≥20%, ≥25%, ≥30%
Cov tsos mob: ntshiab thiab pob tshab kua, tsis muaj ntxhiab tsw ntxhiab.
Cov dej tsis muaj dej: ≤0.006%

2. Lub hom phiaj tseem ceeb:
Txhawm rau kho cov dej phwj hauv nroog, kawm txog kev cuam tshuam ntawm cov hnub nyoog sludge (SRT) thiab cov pa roj carbon monoxide (sodium acetate solution) ntawm qhov system denitrification thiab phosphorus tshem tawm. Sodium acetate yog siv los ua cov pa roj carbon monoxide ntxiv rau kev ua kom cov sludge denitrification, thiab tom qab ntawd siv cov tshuaj tsis haum los tswj qhov nce hauv pH thaum lub sij hawm denitrification hauv thaj tsam ntawm 0.5. Cov kab mob denitrifying tuaj yeem adsorb CH3COONa ntau dhau, yog li thaum siv CH3COONa ua cov pa roj carbon monoxide sab nraud rau denitrification, tus nqi COD effluent kuj tseem tuaj yeem khaws cia ntawm qib qis. Tam sim no, kev kho cov dej phwj tuaj hauv txhua lub nroog thiab cov nroog yuav tsum tau ntxiv sodium acetate ua cov pa roj carbon monoxide kom ua tau raws li cov qauv emissions thawj theem.

Sodium sulfate cov khoom tau muab faib ua cov khoom thiab ua kua ob yam, khoom sodium acetate C2H3NaO2 cov ntsiab lus ≥58-60%, tsos: tsis muaj xim lossis dawb pob tshab siv lead ua. Cov ntsiab lus ntawm sodium acetate kua: cov ntsiab lus ≥20%, 25%, 30%. Cov tsos mob: ntshiab thiab pob tshab kua. Sensory: tsis muaj ntxhiab tsw, dej insoluble teeb meem: 0.006% lossis tsawg dua.

Daim ntawv thov: Sodium acetate yog siv los ua cov pa roj carbon ntxiv hauv cov chaw kho dej phwj tuaj kom ua kom cov av denitrification sludge, uas tuaj yeem tau txais qhov tshwj xeeb denitrification ntau dua. Tam sim no, tag nrho cov dej phwj hauv nroog lossis kev kho dej khib nyiab kom ua tau raws li qib A tus qauv yuav tsum tau ntxiv cov sodium acetate ua cov pa roj carbon.

1. Nws tsuas yog ua lub luag haujlwm ntawm kev tswj hwm tus nqi PH ntawm cov dej phwj tuaj. Nws tuaj yeem hydrolyze hauv dej los tsim OH- tsis zoo ions, uas tuaj yeem nruab nrab acidic ions hauv dej, xws li H +, NH4 + thiab lwm yam. Qhov sib npaug hydrolysis yog: CH3COO- + H2O = thim rov qab = CH3COOH + OH-.

2. Raws li cov pa roj carbon ntxiv, cov tshuaj tsis yog siv los tswj qhov nce ntawm pH tus nqi hauv 0.5 hauv cov txheej txheem denitrification. Cov kab mob denitrifying tuaj yeem overabsorb CH3COONa, yog li COD tus nqi ntawm cov dej ntws tawm tuaj yeem khaws cia ntawm qib qis thaum CH3COONa siv los ua cov pa roj carbon ntxiv rau denitrification. Lub xub ntiag ntawm sodium acetate tam sim no hloov cov pa roj carbon yav dhau los, thiab cov dej sludge ua haujlwm ntau dua tom qab siv.

3. Nws ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg ntawm cov dej zoo. Hauv cov dej phwj tuaj ntawm nitrite thiab phosphorus, nws tuaj yeem siv rau kev sib koom ua ke, uas tuaj yeem txhim kho qhov kev siv ntawm corrosion inhibition. Yog tias qhov ntsuas tau ua tiav ntawm cov dej sib txawv, me me ntawm qib qib sodium acetate tuaj yeem siv ua ntej kom tau txais qhov tsim nyog. Feem ntau, cov txheej txheem tsim khoom ntawm lub tuam txhab yuav yog cov khoom thiab cov dej sib piv ntawm 1 txog 5, kom ua tiav cov txheej txheem kev sib cais ua ntej ntxiv dej rau dilution.
