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 kwe-denitrification kwesistimu nokususwa kwe-phosphorus.I-sodium acetate isetshenziswa njengomthombo wekhabhoni yokwengeza ukuze kufuywe udaka lwe-denitrification, bese isebenzisa isixazululo se-buffer ukulawula ukwanda kwe-pH phakathi nenqubo yokukhishwa kwe-denitrification phakathi kwebanga elingu-0.5.Amagciwane ahlukanisayo angakhanga i-CH3COONa ngokweqile, ngakho-ke uma usebenzisa i-CH3COONa njengomthombo wekhabhoni yangaphandle ukuze kukhishwe i-denitrification, inani le-COD elingcolile lingagcinwa lisezingeni eliphansi.Njengamanje, ukulahlwa 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.
