sodium formate daws
Main indicators:
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%
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 siv cov denitrification sludge, 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 zaug.
