Zipangizo zoyeretsera zinyalala zapakhomo zopanda mphamvu (thanki yachilengedwe)

Madzi akuda amayamba kulowa mu thanki ya septic yakutsogolo kuti akayeretsedwe, komwe zinyalala ndi matope zimachotsedwa, ndipo supernatant imalowa mu gawo la mankhwala a biochemical la chipangizocho. Imadalira tizilombo toyambitsa matenda m'madzi ndi chodzaza bedi chosuntha pambuyo poti nembanembayo yapachikidwa kuti ichiritsidwe, hydrolysis ndi acidization zimawononga zinthu zachilengedwe, zimachepetsa COD, ndikuchita ammonification. Pambuyo pa mankhwala a biochemical, zinyalala zimalowa mu gawo la mankhwala a physical kumbuyo. Zipangizo zosankhidwa zogwira ntchito zosefera zimafuna kuti ammonia nayitrogeni ilowe, kuletsa zinthu zolimba zomwe zapachikidwa, kupha Escherichia coli, ndi zinthu zothandizira, zomwe zingatsimikizire kuti COD ndi ammonia nayitrogeni zichepa bwino m'madzi otuluka. Potengera kukwaniritsa miyezo yoyambira yothirira, zofunikira zapamwamba zitha kukwaniritsidwa. Mbali ya kumbuyo ikhoza kukhala ndi thanki yowonjezera yamadzi oyera kuti itenge ndikusamalira madzi akumbuyo, kukwaniritsa zofunikira zogwiritsira ntchito zinthu m'madera akumidzi.
