Ts'ebetso le ts'ebeliso ea sodium acetate kalafong ea metsi a litšila
Ts'ebetso le ts'ebeliso ea sodium acetate kalafong ea metsi a litšila,
Mokelikeli oa Sodium Acetate, litlamorao tsa sodium acetate ea metsi, baetsi ba sodium acetate ea metsi, tšebeliso ea sodium acetate ea metsi, Baetsi ba acetate ea sodium,
1. Matšoao a mantlha:
Litaba: ≥20%, ≥25%, ≥30%
Ponahalo: mokelikeli o hlakileng le o bonaletsang, ha ho monko o monate.
Lintho tse sa qhibiliheng ka metsi: ≤0.006%
2. Sepheo sa mantlha:
Ho phekola likhoerekhoere tsa litoropo, ithute tšusumetso ea lilemo tsa seretse (SRT) le mohloli oa khabone ea kantle (sodium acetate solution) ho denitrification ea sistimi le ho tlosoa ha phosphorus. Sodium acetate e sebelisoa e le mohloli oa khabone ea tlatsetso ho kenya seretse sa denitrification lapeng, ebe o sebelisa tharollo ea buffer ho laola keketseho ea pH nakong ea ts'ebetso ea denitrification ka har'a sebaka sa 0.5. Libaktheria tse hlakisang li ka bapa CH3COONa ho feta tekano, kahoo ha u sebelisa CH3COONA e le mohloli oa khabone ea kantle bakeng sa denitrification, boleng ba COD bo ka bolokoa bo le tlase haholo. Hona joale, phekolo ea likhoerekhoere metseng eohle le literekeng e hloka ho eketsa sodium acetate e le mohloli oa carbon ho finyella litekanyetso tsa boemo ba pele ba ho ntša metsi.

Lihlahisoa tsa sodium sulfate li arotsoe ka mefuta e 'meli e tiileng le ea metsi, e tiileng ea sodium acetate C2H3NaO2 content ≥58-60%, ponahalo: kristale e se nang mebala kapa e tšoeu e bonaletsang. Mokelikeli oa sodium acetate content: content ≥20%, 25%, 30%. Ponahalo: Mokelikeli o hlakileng le o bonaletsang. Sensory: ha ho na monko o halefisang, taba e sa tsitsang ea metsi: 0.006% kapa ka tlase.
Kopo: Sodium acetate e sebelisoa e le mohloli oa khabone ea tlatsetso ka har'a limela tsa likhoerekhoere ho lumellana le denitrification sludge, e ka fumanang sekhahla se phahameng sa denitrification. Hajoale, ts'ebetso eohle ea likhoerekhoere tsa masepala kapa ts'ebetso ea metsi a litšila ea liindasteri ho fihlela boemo ba ho lahla A maemo a hloka ho eketsoa ha sodium acetate e le mohloli oa khabone.
1. Haholo-holo e bapala karolo ea ho laola boleng ba PH ea likhoerekhoere. E ka hydrolyze ka metsing ho etsa li-ion tsa OH-negative, tse ka fokotsang li-ion tse nang le asiti ka metsing, joalo ka H +, NH4 + joalo-joalo. Thepa ea hydrolysis ke: CH3COO-+H2O= e ka khutlisetsoang morao =CH3COOH+OH-.
2. Joalo ka mohloli oa khabone ea tlatsetso, tharollo ea buffer e sebelisoa ho laola ho phahama ha boleng ba pH ka har'a 0.5 ts'ebetsong ea denitrification. Libaktheria tse hlakisang li ka monya CH3COONa ho feta tekano, kahoo boleng ba COD ba litšila bo ka bolokoa bo le tlase haholo ha CH3COONA e sebelisoa e le mohloli o mong oa khabone bakeng sa denitrification. Ho ba teng ha sodium acetate hona joale ho nka sebaka sa mohloli o fetileng oa carbon, 'me seretse sa metsi se sebetsa haholoanyane ka mor'a tšebeliso.
3. E phetha karolo ea bohlokoa ho tsitsang ha boleng ba metsi. Ka likhoerekhoere tsa nitrite le phosphorus, e ka sebelisoa bakeng sa phello ea ho hokahanya, e ka ntlafatsang matla a ho thibela kutu. Haeba tlhahlobo e etsoa mehloling e fapaneng ea metsi, palo e nyane ea sodium acetate ea boemo ba indasteri e ka sebelisoa pele ho fumana litekanyetso tse nepahetseng. Hangata, ts'ebetso ea tlhahiso ea khoebo e tla ba karo-karolelano e tiileng le ea metsi ea 1 ho isa ho 5, ho phethela ts'ebetso ea ho qhala pele o eketsa metsi bakeng sa dilution.
