Tsebo le Tšebeliso ea Phekolo ea Likhoerekhoere

I.Sewage ke eng?

Likhoerekhoere li bolela metsi a tsoang mesebetsing ea tlhahiso le ea bophelo. Batho ba sebelisa metsi a mangata bophelong ba letsatsi le letsatsi le mesebetsing ea tlhahiso, 'me metsi ana a atisa ho silafala ka tekanyo e sa tšoaneng. Metsi a silafetseng a bitsoa likhoerekhoere.

II.Joang ho tšoara likhoerekhoere?

Ho hloekisa likhoerekhoere ho akarelletsa ho sebelisa mahlale a sa tšoaneng le mekhoa ea ho arola, ho ntša le ho sebelisa lintho tse silafatsang ka har'a likhoerekhoere kapa ho li fetola lintho tse se nang kotsi, kahoo ho hloekisa metsi.

III.Kopo ea phekolo ea lik'hemik'hale ka har'a likhoerekhoere?

Phekolo ea lik'hemik'hale ea likhoerekhoere e sebelisa mekhoa ea bophelo ba likokoana-hloko ho tlosa lintho tse qhibilihang ka har'a metsi le lintho tse ling tse sa tsitsang tse tsoang metsing a litšila, ho hloekisa metsi.

IV.Tlhaloso ea libaktheria tsa aerobic le anaerobic?

Aerobic bacteria: Libaktheria tse hlokang boteng ba oksijene e sa lefelloeng kapa ha li felisoe ka pel'a oksijene ea mahala. Anaerobic bacteria: Libaktheria tse sa hlokeng oksijene ea mahala kapa ha li felisoe ha ho se na oksijene ea mahala.

V.Kamano pakeng tsa mocheso oa metsi le ts'ebetso?

Mocheso oa metsi o ama haholo ts'ebetso ea litanka tsa aeration. Setsing sa ho hloekisa likhoerekhoere, mocheso oa metsi o fetoha butle-butle le linako tsa selemo 'me ha o fetohe ka hare ho letsatsi. Haeba liphetoho tse kholo li hlokomeloa ka hare ho letsatsi, tlhahlobo e lokela ho etsoa ho hlahloba metsi a pholileng a indasteri. Ha mocheso oa metsi oa selemo le selemo o le ka har'a 8-30 ℃, ts'ebetso ea kalafo ea tanka ea aeration e fokotseha ha e sebetsa ka tlase ho 8 ℃, 'me sekhahla sa ho tlosa BOD5 hangata se ka tlase ho 80%.
