Qhib Aluminatuaj yeem tshem tawm arsenic los ntawm qee yam kev mob, tab sis nws cov txiaj ntsig nyob ntawm ntau yam, pH, kev kho tsiaj, thiab cov kev kho mob tshwj xeeb ntawm cov khoom.
Adsorption mechanism ntawm arsenic
Ua kom Alumina tshem tawm cov arsenic feem ntau yog los ntawm kev ua yeeb yam thiab}} dua li (v)
Kev sib tw ua ke (xws li (III)) feem ntau yog nyob rau hauv daim ntawv tsis-ionication (xws li muaj poov xab ua ntej (v) .
Zais Cov Lus Qhia
• pH value: The optimal adsorption pH range is 5~7 (for As(V)). When the pH is too high (>8), tus nqi tsis zoo nyob rau saum npoo ntawm Alumina nce ntxiv, rov ua dua arsenate ions; Thaum lub p yog tsawg dhau (<4), alumina may dissolve.
• Sib tw ions: phosphates, silicates, sulfates, thiab lwm yam {{{0} {{.
• Sijhawm Hu thiab Dosage: Lub sij hawm muaj kev sib cuag thiab tsim nyog noj tshuaj alumina yuav tsum tau .
Daim Ntawv Thov Kev Ua Haujlwm Alumina Rau Arsenic Tshem Tawm
• Kev tshem tawm hauv av arsenic tshem tawm (siv rau cov dej lub cev yeej los ntawm AS (V)) .
• Tsev neeg me me lossis cov dej hauv zej zog (xws li cov tso tsheb hlau luam lim, lim lim).
• Muaj Wastewaterater Pretreatment (yuav tsum tau cov kauj ruam oxidation) .
Cov kev txwv ntawm kev tshem tawm arsenic los ntawm kev ua haujlwm Alumina
{{01.} qis li (iii) tus nqi tshem tawm, xav tau ib kauj ruam ntxiv oxidation .
2.} cuam tshuam los ntawm kev sib tw ions, phosphaates, silicates, silicates, sitic} puas tuaj yeem txo kev ua haujlwm.
3. Limited adsorption capacity, not suitable for high arsenic concentration water (>1 mg / l) .
4. Tus nqi rov tsim txiaj siab, ua tau zoo degrades tom qab rov siv dua.
Qhib Aluminatuaj yeem siv rau kev tshem tawm arsenic, tshwj xeeb tshaj yog rau cov dej nruab nrab ntawm PE, cov kev sim ua ntej, thiab kev sim ua ntej me me, lossis xav txog cov txheej txheem sib xyaw ua ntej, lossis xav txog cov txheej txheem sib xyaw ua ntej, lossis xav txog cov txheej txheem sib xyaw ua ntej efficion .
