Umsebenzi kanye nokusetshenziswa kwe-sodium acetate ekwelashweni kwamanzi angcolile,
I-Liquid Sodium Acetate, imiphumela ye-sodium acetate ye-liquid, abakhiqizi be-sodium acetate, ukusetshenziswa kwe-sodium acetate, Abakhiqizi be-sodium acetate,
1. Izinkomba eziyinhloko:
Okuqukethwe: ≥20%, ≥25%, ≥30%
Ukubukeka: uketshezi olucacile futhi olusobala, alukho iphunga elicasulayo.
Amanzi angancibiliki: ≤0.006%
2. Injongo eyinhloko:
Ukwelapha indle yasemadolobheni, funda umthelela weminyaka yodaka (SRT) kanye nomthombo wekhabhoni wangaphandle (isixazululo se-acetate ye-sodium) ekukhishweni kwesistimu nokususwa kwe-phosphorus. I-sodium acetate isetshenziswa njengomthombo wekhabhoni yokwengeza ukuze kufuywe udaka lwe-denitrification, bese kusetshenziswa isisombululo se-buffer ukulawula ukwanda kwe-pH phakathi nenqubo yokukhishwa kwe-denitrification phakathi kwebanga elingu-0.5. Ibhaktheriya ehlukanisayo ingakhanga i-CH3COONa ngokweqile, ngakho-ke uma usebenzisa i-CH3COONA njengomthombo wekhabhoni yangaphandle ukuze i-denitrification, inani le-COD elingcolile lingagcinwa lisezingeni eliphansi. Njengamanje, ukuhlanzwa kwendle kuwo wonke amadolobha nezifunda kudinga ukwengeza i-sodium acetate njengomthombo wekhabhoni ukuze kuhlangatshezwane namazinga okuphuma kwezinga lokuqala.

Imikhiqizo ye-sodium sulfate ihlukaniswe yaba yizinhlobo ezimbili eziqinile neziwuketshezi, okuqukethwe kwe-sodium acetate C2H3NaO2 okuqinile ≥58-60%, ukubukeka: ikristalu esobala engenambala noma emhlophe. Okuqukethwe kwe-acetate ye-sodium ewuketshezi: okuqukethwe ≥20%, 25%, 30%. Ukubukeka: Uketshezi olucacile futhi olusobala. Izinzwa: alikho iphunga elicasulayo, into engancibiliki emanzini: 0.006% noma ngaphansi.
Isicelo: I-sodium acetate isetshenziswa njengomthombo wekhabhoni owengeziwe ezitshalweni zokuhlanza indle ukuze ijwayeze udaka lwe-denitrification, olungathola izinga elithile eliphakeme le-denitrification. Njengamanje, wonke amapayipi endle kamasipala noma ukuhlanzwa kwamanzi angcolile ezimbonini ukuze kuhlangatshezwane nezinga lokukhishwa A lidinga ukungezwa kwe-sodium acetate njengomthombo wekhabhoni.
1. Ngokuyinhloko idlala indima yokulawula ukubaluleka kwe-PH yendle. Ingakwazi ukwenza i-hydrolyze emanzini ukuze yenze ama-ion e-OH-negative, anganciphisa ama-ion ane-asidi emanzini, njenge-H+, NH4+ nokunye. Isibalo se-hydrolysis sithi: CH3COO-+H2O= reversible =CH3COOH+OH-.
2. Njengomthombo wekhabhoni owengeziwe, isixazululo se-buffer sisetshenziswa ukulawula ukukhuphuka kwenani le-pH phakathi kuka-0.5 ngenqubo ye-denitrification. I-Denitriifying bacteria ingamunca ngokweqile i-CH3COONa, ngakho-ke inani le-COD lamanzi angcolile lingagcinwa lisezingeni eliphansi lapho i-CH3COONA isetshenziswa njengomthombo owengeziwe wekhabhoni wokukhishwa kwe-denitrification. Ukuba khona kwe-sodium acetate manje sekungena esikhundleni somthombo wekhabhoni wangaphambilini, futhi udaka lwamanzi lusebenza kakhulu ngemva kokusetshenziswa.
3. Idlala indima ebalulekile ekuzinzeni kwezinga lamanzi. Ekuthunjweni kwendle ye-nitrite ne-phosphorus, ingasetshenziselwa umphumela wokuxhumanisa, ongathuthukisa ukuqina kokuvinjelwa kokugqwala. Uma ukuhlolwa kwenziwa emithonjeni yamanzi ehlukene, inani elincane le-sodium acetate yezinga lezimboni lingasetshenziswa kuqala ukuze kutholwe umthamo ofanele. Ngokuvamile, inqubo yokukhiqiza yebhizinisi izoba isilinganiso esiqinile nesamanzi sika-1 kuya ku-5, ukuze kuqedelwe inqubo yokuhlakaza ngaphambi kokwengeza amanzi okuhlanjululwa.
