Tšebeliso ea sodium thiosulfate ho aquaculture
Lik'hemik'haleng tsa phetisetso ea metsi le ntlafatso e tlase, lihlahisoa tse ngata li na le sodium thiosulfate . Ke moriana o motle bakeng sa ho laola boleng ba metsi, ho tlosa chefo le ho bolaea cyanobacteria le green algae. E latelang, e re ke u bontše haholoanyane ka sodium thiosulfate
1. Ho ntša chefo
E na le phello e itseng ea ho tlosa chefo ho pholosa chefo ea cyanide matangoaneng a litlhapi, 'me mosebetsi oa eona o motle oa phapanyetsano ea ion o na le phello e itseng ho fokotsa chefo ea litšepe tse boima ka metsing.
E na le phello ea detoxification ho lithethefatsi tse boima ba tšepe tse kang koporo sulfate le ferrous sulfate e sebelisetsoang ho bolaea likokoanyana. Ione ea sulphur ea sodium thiosulfate e ka sebetsana le li-ion tsa tšepe e boima ho etsa pula e se nang chefo, e le ho fokotsa chefo ea li-ion tsa tšepe e boima.
E ka sebelisoa ho theola chefo ea chefo e bolaeang likokoanyana. Phokotso ea eona e ntle e ka sebelisoa ho theola chefo ea chefo e bolaeang likokoanyana ea organophosphorus. Ho itloaetsa ho ipakile hore e loketse matšoao a chefo ea litlhapi e bakoang ke chefo e feteletseng ea organophosphorus le chefo ea batho matangoaneng a litlhapi. Likokoana-hloko tsa Organophosphorus tse atisang ho sebelisoa lihlahisoa tsa metsing ke Phoxim le trichlorfon, tse sebelisoang haholo ho bolaea likokoana-hloko. Kamora ho sebelisoa, sodium thiosulfate e ka sebelisoa ho tlosa chefo e setseng.
2. Ho senyeha ha nitrite
Tabeng ea nitrite e phahameng ka metsing, sodium thiosulfate e ka itšoara ka nitrite ka potlako le ho fokotsa kotsi ea chefo e bakoang ke khatello e phahameng ea nitrite metsing.
3. Ntša chlorine e setseng metsing
Ka mor'a ho hloekisa letamo, litokisetso tsa chlorine tse kang bleaching powder li tla sebelisoa libakeng tse ling. Ka mor'a matsatsi a mararo kapa a mane a ho sebelisa metsoako ea chlorine, sodium thiosulfate e ka sebetsana le calcium hypochlorite e nang le oxidation e matla ho hlahisa li-ion tsa chloride tse se nang kotsi, tse ka kenngoa ka letamong esale pele.
4. Ho pholile le ho tlosa mocheso o tlase
Nakong ea mocheso o phahameng, ka lebaka la mocheso o phahameng o tsoelang pele, metsi a ka tlaase a letamo a atisa ho futhumala ka lekhetlo la pele le har'a bosiu, e leng se seng sa lisosa tsa hypoxia bosiu le hoseng. Ha metsi a tlase a letamo a futhumala, a ka rarolloa ka ho sebelisa sodium thiosulfate. Ka kakaretso, e ka fafatsoa ka ho toba mantsiboea, empa hobane oksijene e qhibilihisitsoeng e ka fokotseha ka mor'a tšebeliso ea sodium thiosulfate, e lokela ho sebelisoa hammoho le oksijene ka hohle kamoo ho ka khonehang.
5. Kalafo ea metsi a matšo le metsi a khubelu a bakoang ke algae e khelohileng
Ka lebaka la adsorption le ho rarahana ha sodium thiosulfate, e na le phello e matla ea tlhoekiso ea metsi. Ka mor'a ho tšela algae, algae e shoeleng e senyeha ho ba li-macromolecule tse sa tšoaneng le limolek'hule tse nyenyane tsa lintho tse phelang, ho etsa hore metsi a shebahale a le matšo kapa a khubelu. Sodium thiosulfate e na le phello e rarahaneng, e ka kopanyang li-macromolecules tsena le limolek'hule tse nyenyane tsa lintho tse phelang, e le ho finyella phello ea ho phekola metsi a matšo le metsi a khubelu.
6. Ntlafatso ea boleng ba metsi
E sebelisoa ho ntlafatsa boleng ba metsi a letamo. 1.5g sodium thiosulfate e sebelisoa bakeng sa cubic meter e 'ngoe le e' ngoe ea 'mele oa metsi o fafalitsoeng ka letamong lohle, ke hore, 1000g (2 kg / mu) e sebelisoa bakeng sa mithara e' ngoe le e 'ngoe ea botebo ba metsi.
Ka kakaretso, tšebeliso ea sodium thiosulfate pele ho phetoho e ka tlaase e na le liphello tse thusang, e 'ngoe ke ho tlosa chefo, e' ngoe ke ho adsorb le ho eketsa pepeneneng ea 'mele oa metsi.
Tšebeliso ea kamehla ea sodium thiosulfate ka 'mele oa metsi a aquaculture e ka ntlafatsa haholo alkalinity eohle ea' mele oa metsi le ho eketsa botsitso ba 'mele oa metsi, haholo-holo pele le nakong ea pula, e ka thibelang ho etsahala ha metsi ka mor'a pula.
7. Fokotsa tlhahiso ea hydrogen sulfide matangoaneng
Rea tseba hore boemo bo phahameng ba hydrogen sulfide ke mocheso o phahameng le metsi a nang le asiti (pH e tlase). Boleng ba pH ba matangoana a tloaelehileng a aquaculture ka kakaretso ke alkaline (7.5-8.5). Sodium thiosulfate ke ea alkali e matla le letsoai le fokolang la acid. Ka mor'a hydrolysis, ke alkaline, e tla eketsa pH boleng ba 'mele oa metsi, ho eketsa botsitso ba' mele oa metsi, le ho fokotsa tlhahiso ea hydrogen sulfide ho isa tekanyong e itseng.
Maemo a mang a sebetsang ho sodium thiosulfate
1. Phekolo ea metsi a seretse le a masoeu.
2. E sebelisoa pele le nakong ea pula, e ka phetha karolo ea bohlokoa ho tsitsisa metsi le ho thibela algae ho tšolla le ho senyeha ha metsi ka mor'a pula.
3. Tlosa masalla a halogen a kang chlorine dioxide le bleaching powder. Ka nako e ts'oanang, e ka boela ea sebelisoa bakeng sa ho tlosa chefo e bolaeang likokoanyana ea organophosphorus, cyanide le litšepe tse boima.
4. E sebelisetsoa ho sesa le ho lula ha shrimp le crab e bakoang ke mocheso o tlase har'a mpa ea bosiu; Leha ho le joalo, tabeng ea hypoxia ka halofo ea bobeli ea bosiu, ho ke ke ho hlokahala hore ho sebelisana le ho sebelisa oksijene phetolo tlaase le granular oksijene, 'me a ke ke a itšetleha ka sodium thiosulfate mong bakeng sa hypoxia thuso ea pele.
5. Thiosulfate ea sodium e ka sebelisoa bakeng sa ho hloekisa lipoleiti tse tlase tse mosehla le tse ntšo tsa makhala a noka.
Litaelo tsa ho sebelisa sodium thiosulfate
1. U se ke ua sebelisa hlooho e phaphametseng e bakoang ke ho tšeloa ha algae, hlooho e phaphametseng, matsatsi a maru le a lipula le ammonia nitrogen e phahameng ka hohle kamoo ho ka khonehang ho thibela tahlehelo ea kotsi. E ka sebelisoa esita le maemong a leholimo a mabe, empa ho molemo ho e sebelisa hammoho le oksijene kapa ho bula oksijene ka hohle kamoo ho ka khonehang.
2. Ha sodium thiosulfate e sebelisoa metsing a leoatle, 'mele oa metsi o ka' na oa fetoha pherekano kapa oa ntšofala, e leng ntho e tloaelehileng.
3. Sodium thiosulfate e ke ke ea bolokoa kapa ea tsoakoa le lintho tse matla tsa asiti.
