1. Ka'idar aikin tace anaerobic nazarin halittu
1) Tace: mai filler ya shiga tsakani kuma yana tace manyan barbashi da daskararru da aka dakatar a cikin ruwa mai shiga;
2) Hydrolysis: Anaerobic microorganisms na iya samar da abubuwa masu narkewa na macromolecules a cikin abubuwa masu narkewa na ƙananan ƙwayoyin cuta;
3) Shayewa: ƙananan ƙwayoyin cuta anaerobic suna adsorb da kuma shayar da gurɓataccen yanayi a cikin ruwa, wani ɓangare na abin da ake amfani da su don girma da kuma haifuwa, kuma wani ɓangare na abin da aka rufe ta hanyar ruwa mai siffar U a cikin nau'i na biogas;
4) Denitrification: An mayar da maɓuɓɓugar da ke fitowa daga gadon oxidation na lamba zuwa matatar anaerobic, kuma kwayoyin cutar da ke cikin kwayoyin anaerobic zasu iya amfani da nitrate nitrogen a cikin ruwan reflux kuma su canza shi zuwa nitrogen don cire nitrogen a cikin najasa. Bayan kula da najasa na karkara ta hanyar tace anaerobic, an rage yawan adadin daskararrun da aka dakatar, gurɓataccen gurɓataccen yanayi da nitrogen, sannan kuma an rage nauyin gado na lamba oxidation na gaba.
2. Ka'idar aiki na gadon oxidation na lamba
1) Adsorption: microorganisms na aerobic suna samar da biofilms tare da babban yanki mai girma da kuma maida hankali a lokacin girma da tsarin haifuwa na filler, wanda zai iya yin amfani da mafi yawan gurɓataccen kwayoyin halitta a cikin ruwa a cikin ruwa mai yawa kuma ya rage yawan gurɓataccen abu;
2) Cikowa da rubewa: A yanayin ci gaba da kwararar iska zuwa ga reactor, kwayoyin halittun aerobic na iya daukar gurbatattun kwayoyin halitta a cikin jiki a matsayin sinadirai kuma su metabolize su, wani bangare na abin da ake amfani da shi don girma da haifuwa, kuma wani bangare na abin da ake amfani da shi don girma da haifuwa. an canza shi zuwa carbon dioxide da ruwa. Fitar da gadon hydrogenated yana ƙara rage yawan gurɓataccen gurɓataccen ruwa a cikin najasar ƙauye, kuma yawan cirewar CODcr da BOD5 a cikin datti ya kai fiye da 80%, wanda zai iya cika ka'idojin sakandare na ƙasa don fitar da najasa.
