The experiment investigated the optimal mixing proportion of treating landfill leachate, fecal sewage mixed with domestic sewage synchronously and the optimal running conditions for the removal efficiency of nitrogen by an orthogonal array test. A confirmatory experiment was also carried out to verify the optimal parameters obtained by the orthogonal array test. The results showed that: the optimal volume ratio of landfill leachate, fecal sewage and urban wastewater in the A2/O process was 1:3.75:1000. The average removal efficiency of NH3-N, TN and COD can reach 96%, 61% and 85% respectively under the conditions of hydraulic retention time (HRT) of 11h, dissolved oxygen (DO) of 3 mg L-1 the mixed-liquid return ratio (r) of 200% and sludge return ratio (R) of 80%. </p></abstract><publication_date><month>04</month><day>30</day><year>2013</year></publication_date><pages><first_page>181</first_page><last_page>189</last_page></pages><publisher_item><identifier id_type="pii">620</identifier></publisher_item><doi_data><doi>10.30955/gnj.000620</doi><timestamp>1714049783</timestamp><resource>https://journal.gnest.org/publication/620</resource></doi_data></journal_article></journal></body></doi_batch> </div>
