LD Household Septic tank

Madzi akuda amayamba kulowa kutsogolo kwa septic tank kuti ayambe kulandira chithandizo, kumene scum ndi sediment amachotsedwa, ndipo supernatant imalowa mu gawo la mankhwala a biochemical la zipangizo. Zimadalira tizilombo tating'onoting'ono tomwe timakhala m'madzi ndi chodzaza bedi losuntha pambuyo popachikidwa nembanemba kuti ichiritsidwe, hydrolysis ndi acidification imawononga zinthu zachilengedwe, kuchepetsa COD, ndikuchita ammonification. Pambuyo pa mankhwala a biochemical, zimbudzi zimalowa mu gawo lachidziwitso cha backend. Zosefera zomwe zasankhidwa zimayang'ana kutulutsa kwa ammonia nitrogen, kutenga zolimba zomwe zayimitsidwa, kupha Escherichia coli, ndi zida zothandizira, zomwe zingathandize kuchepetsa COD ndi ammonia nayitrogeni m'madzi. Pamaziko a kukwaniritsa mfundo zoyambira za ulimi wothirira, zofunikira zapamwamba zingatheke. Kumbuyo kwake kumatha kukhala ndi tanki yowonjezera yamadzi oyera kuti asonkhanitse ndi kuthira madzi amchira, kukwaniritsa zofunikira pakugwiritsa ntchito zinthu zakumidzi.
