tshebediso ya polyferric sulfate ka aquaculture

2025-08-27

Polyferric sulfate (PFS) e sebelisoa e le mokhoa o hloahloa oa boleng ba metsi le ntlafatso ea sediment temong ea metsing. E ka ntlafatsa haholo tikoloho ea aquaculture ka flocculation, precipitation, oxidation, decomposition le tlatsetso ea limatlafatsi. Lisebelisoa tse khethehileng ke tse latelang:

I. Tlhoekiso ea Metsi

Tlosa lintho tse silafatsang
- Ho na ka potlako ho fanyeha lintho tse phelang le li-ion tse boima, ho fokotsa moferefere oa metsi le ho ntlafatsa pepeneneng.
- Ho senyeha ha lintho tse kotsi tse kang ammonia nitrogen, nitrite, hydrogen sulfide, COD/BOD, joalo-joalo, taolo ea boleng ba pH ea metsi, le ho boloka botsitso ba tikoloho.

Oksijene le ponaletso li ile tsa eketseha
- Granular PFS e kenngoa 'me e qhibiliha butle-butle ka tlaase ho letamo la sedimentation ho ntšetsa pele convection pakeng tsa' mele oa metsi a ka holimo le a tlaase le ho eketsa oksijene e qhibilihisitsoeng. Ketane ea eona ea limolek'hule e etsa hore metsi a hloeke, a be khanyang 'me a etse hore lintho tse phelang metsing li fumane khanya.

🌱 II. Ntlafatso ea libethe

Sediment e bolang
- Bolisa lintho tse phelang le metabolites ea likokoana-hloko ka tlaase ho sediment, ho ntlafatsa ho phunyeletsa le boemo ba oxidation ea sediment, le ho fokotsa ho lokolloa ha lintho tse kotsi.

Sebelisana le biological bottoming
- Ka mor'a hore PFS e oxidize le ho senya macromolecular organic matter ka limolek'hule tse nyenyane, e hloka ho kopanngoa le libaktheria tsa EM, libaktheria tsa photosynthetic le litokisetso tse ling tsa likokoana-hloko ho finyella ho senyeha ho feletseng ha lintho tse phelang.

🌿 III. Taolo ea algae le tlatsetso ea limatlafatsi

Thibela algae e kotsi
- Laola kholo e feteletseng ea algae (joalo ka lithunthung tsa algal) le ho boloka ho hlaka ha metsi.

Khothaletsa kholo ea algae e molemo
- Fe³⁺ e hlahisoang ke hydrolysis e monngoa ke algae ho matlafatsa photosynthesis le bokhoni ba kholo; Fe²⁺ e kena ka har'a mala a liphoofolo tsa metsing ho ntlafatsa tšireletso ea 'mele le lebelo la ho phela.

Ea bone, ho matlafatsa khanyetso ea likokoana-hloko khahlanong le maloetse

Thibelo ea li-fungus: thibela likokoana-hloko tsa pathogenic le libaktheria tse kotsi, fokotsa sekhahla sa litlhapi, li-shrimp le crab, ho ntlafatsa lebelo la ho pholoha.
Khothalletsa khōlo: tšepe ea tlatsetso e ka ntlafatsa ho tiea ha lintho tsa ho ikatisa, 'me batho ba baholo ba kholo ebile ba monate.

⚠ V. Lintlha tsa Tšebeliso

sebaka se sebetsang
- E loketse matamo a khale a nang le litšila tse ngata, matangoana a nang le metsi a matšo le a nkhang hamonate nakong ea morao-rao ea aquaculture, le matangoana a shrimp, tlhapi le crab.
- Nako e ntle ka ho fetisisa: mokhahlelo o bohareng le oa morao oa temo ea metsing (nako ea tlhōrō ea ho bokellana ha lintho tse phelang ka har'a sediment).

Lintlha tsa bohlokoa tsa ts'ebetso
- Taolo ea litekanyetso: tšebeliso e feteletseng e bonolo ho lebisa ho theoha ka tšohanyetso ho metsi pH (PFS tharollo pH = 2 ~ 3), e tla senya bophelo ba metsing.
- Ha e lumellane: qoba ho kopanya le sebolaya ditwatsi le flocculant; u se ke ua sebelisa matsatsing a lipula kapa a haelloang ke oksijene.
- Tlhokomelo ea boleng ba metsi: hlahloba pH ea 'mele oa metsi pele o sebelisoa ho netefatsa hore e ka har'a 6 ~ 9.

💎 VI. Lisebelisoa tse atolositsoeng

Ho lengoa ha limela tsa metsing: ho sebelisoa bakeng sa motso oa lotus, li-chestnut tsa metsi le temo ea limela tse ling tsa metsi a hloekileng, ho thibela tšoaetso ea baktheria le tšepe ea tlatsetso, ho khothalletsa chai.
