1. Molao-motheo oa ketso ea anaerobic baeloji filthara
1) Filtration: filler e kenella le ho sefa likaroloana tse kholo le lintho tse tiileng tse emisitsoeng ka metsing a kenang;
2) Hydrolysis: anaerobic microorganisms ka hydrolyze lintho tse insoluble tsa macromolecules ka lintho tse qhibilihang ka har'a limolek'hule tse nyenyane;
3) Ho monya: likokoana-hloko tsa anaerobic li adsorb le ho monya litšila tse phelang metsing, tseo karolo ea tsona e sebelisetsoang khōlo ea tsona le ho ikatisa, 'me karolo ea eona e tiisitsoe ka metsi a bōpehileng joaloka U ka mokhoa oa biogas;
4) Denitrification: Mokelikeli o tsoang betheng ea ho kopana le oxidation o khutlisetsoa sefang sa anaerobic, 'me libaktheria tse khethollang likokoana-hloko tsa anaerobic li ka sebelisa naetrojene ea nitrate metsing a reflux le ho e fetola naetrojene ho tlosa naetrojene ka har'a likhoerekhoere. Ka mor'a ho phekoloa ha likhoerekhoere tsa mahaeng ka filthara ea anaerobic, ho fokotseha ha lintho tse thata tse emisitsoeng, lintho tse silafatsang tsa manyolo le naetrojene, 'me moroalo o latelang oa bethe ea ho kopana le oxidation o boetse oa fokotseha.
2. Molao-motheo oa ketso ea bethe ea ho kopana le oxidation
1) Adsorption: li-microorganisms tsa aerobic li etsa li-biofilms tse nang le sebaka se seholo le ho tsepamisa mohopolo haholo nakong ea kholo le ts'ebetso ea ho ikatisa ea li-filler, tse ka khantšang boholo ba lintho tse silafatsang tse phelang metsing ka bongata le ho fokotsa khatello ea tšilafalo;
2) Ho noa le ho bola: Ha moea o tsoela pele ho phalla ho ea ho reactor, likokoana-hloko tsa aerobic li ka nka lintho tse silafatsang tse adsorbed 'meleng e le limatlafatsi le ho li fetola, karolo ea tsona e sebelisetsoa ho hōla le ho ikatisa, le karolo ea eona. e fetoloa carbon dioxide le metsi. Ho pepesetsoa betheng ea hydrogenated ho fokotsa le ho feta ho fokotsa bongata ba lintho tse silafatsang ka har'a likhoerekhoere tsa mahaeng, 'me sekhahla sa ho tlosoa ha CODcr le BOD5 ka litšila se fihla ho feta 80%, e ka finyellang maemo a bobeli a naha bakeng sa ho ntša likhoerekhoere.
