Gukoresha sodium acetate mu ruganda rutunganya imyanda

Gukoresha sodium acetate mu ruganda rutunganya imyanda,
Umuti wa sodium acetate yubushinwa, Abashinwa sodium acetate itanga, Sodium Acetate, ingaruka za sodium, sodium acetate ingaruka no gukoresha, Sodium acetate ikora, Sodium Acetate Umuti, sodium acetate ikora, sodium acetate, sodium acetate ikoresha,
1. Ibipimo nyamukuru:
Ibirimo: ≥20%, ≥25%, ≥30%
Kugaragara: amazi meza kandi meza, nta mpumuro mbi.
Ikintu kidashonga amazi: ≤0.006%

2. Intego nyamukuru:
Kugira ngo utunganyirize imyanda yo mu mijyi, wige ingaruka zimyaka (SRT) nisoko ya karubone yo hanze (sodium acetate solution) kuri sisitemu yo gukuraho no gukuraho fosifore. Sodium acetate ikoreshwa nkisoko yinyongera ya karubone kugirango yinjize umwanda wa denitrification, hanyuma ukoreshe igisubizo cya buffer kugirango ugenzure ubwiyongere bwa pH mugihe cya denitrification murwego rwa 0.5. Kwanduza bagiteri birashobora kwamamaza CH3COONa birenze urugero, mugihe rero ukoresheje CH3COONa nkisoko ya karubone yo hanze kugirango itandukane, agaciro ka COD gasohoka nako gashobora kugumaho kurwego rwo hasi. Kugeza ubu, gutunganya imyanda mu mijyi yose no mu ntara bigomba kongeramo sodium acetate nkisoko ya karubone kugira ngo byuzuze urwego rwa mbere rw’ibyuka bihumanya ikirere.

Sodium acetate igira uruhare runini mugutunganya agaciro ka PH mugutunganya imyanda. Sodium acetate ni imiti ya alkaline ishobora guhindurwa hydrolyz kugirango ibe OH- mbi mu mazi, ishobora kwanduza ioni ya acide mu mazi, nka H +, NH4 +, n'ibindi. Acetate ya Sodium yakoreshejwe cyane mu nganda zitunganya amazi mabi mu myaka yashize. , ariko uzi uko ikoreshwa? Uyu munsi, inyandiko ntoya ya Hebei Pengfa izaganira nawe.

Mbere na mbere, sodium acetate ntabwo yakoreshejwe mu nganda zitunganya amazi, buri gihe yakoreshwaga mu nganda zo gucapa no gusiga amarangi. Gusa kubera ko inganda zitunganya imyanda zitera imbere mumyaka yashize, kandi hakenewe rwose acetate ya sodium kugirango tunoze intego yo gutunganya imyanda. Niyo mpamvu ikoreshwa mu nganda zanduye. Sodium acetate yakoreshejwe nkisoko yinyongera ya karubone kugirango imenyekanishe umwanda wa denitrification, hanyuma igisubizo cya buffer cyakoreshejwe mukugenzura izamuka ryagaciro ka pH mubikorwa bya denitrification murwego 0.5. Guhagarika bagiteri birashobora kurenza CH3COONa, bityo agaciro ka COD yimyanda irashobora kugumana kurwego rwo hasi mugihe CH3COONa ikoreshwa nkisoko yinyongera ya karubone kugirango yamagane. Kugeza ubu, gutunganya imyanda yose yo mu mijyi no mu ntara kugira ngo yuzuze ibipimo bisohoka bisaba kongeramo sodium acetate (sodium acetate) nkisoko ya karubone.
