eena tlhaho ea drainage ea sepetlele e etsa qeto ea boleng bo sa lekaneng ba metsi a kenang ho tloha setsing sa ho hloekisa likhoerekhoere.Ka hona, tanka e laolang e thehiloe ho homogenize boleng le bongata ba likhoerekhoere le ho fokotsa tšusumetso ea meroalo ea tšusumetso litsing tse latelang tsa kalafo.Ka nako e ts'oanang, theha phaephe e fetisang kotsi ho letamo la kotsi.Thepa ea moea e kentsoe ka tankeng e laolang ho thibela sedimentation ea likaroloana tse emisitsoeng le ho ntlafatsa biodegradability ea metsi a litšila.
③ Letamo la Hypoxic aerobic
Anoxic aerobic tank ke mokhoa oa mantlha oa ho hloekisa likhoerekhoere.Molemo oa eona ke hore ntle le ho senya litšila tse phelang, e boetse e na le mosebetsi o itseng oa ho tlosoa ha nitrogen le phosphorus.Mokhoa oa A / O o kopanya karolo e ka pele ea anaerobic le karolo e ka morao ea aerobic ka letoto, le karolo ea A e sa feteng 0.2 mg / L le O karolo ea DO = 2 mg / L-4 mg / L.
Mokhahlelong oa anoxic, libaktheria tsa heterotrophic hydrolyze tse silafatsang tse emisitsoeng joalo ka starch, likhoele, lik'habohaedreite le lintho tse qhibilihang ka har'a likhoerekhoere hore li be li-organic acid, e leng se etsang hore macromolecular organic matter e bole hore e be molek'hule e nyane.Lintho tse phelang tse sa qhibiliheng li fetoloa lintho tse phelang tse qhibilihang.Ha lihlahisoa tsena tsa anaerobic hydrolysis li kena ka tanka ea aerobic bakeng sa phekolo ea aerobic, biodegradability ea likhoerekhoere e ea ntlafala le katleho ea oksijene ea ntlafala.
Karolong ea anoxic, libaktheria tsa heterotrophic ammonifies litšila tse kang protheine le mafura (N ho ketane ea tlhaho kapa amino acid ka har'a amino acid) ho lokolla ammonia (NH3, NH4 +).Tlas'a maemo a lekaneng a phepelo ea oksijene, nitrification ea libaktheria tsa autotrophic oxidizes NH3-N (NH4+) ho NO3 -, 'me e khutlela letamong la A ka taolo ea reflux.Tlas'a maemo a anoxic, denitrification ea libaktheria heterotrophic fokotsa NO3 - ho molek'hule naetrojene (N2) ho phethela potoloho ea C, N, le O ka tikoloho le ho hlokomela se nang kotsi likhoerekhoere kalafo.
