Simultaneous organic and nitrogen removal from municipl landfill leachate using an anaerobic-Aerobic system

摘要

An anaerobic-aerobic system including simulaneous methanogenesis and denitrification was introduced to treat organic and nitrogen compounds in immature leachate from a landfill site. Denitrification and methanogenesis were successfully carried out in the anaerobic reactor while the organic Removal and nitrification of NH_4-N were carried out in the aerobic reactor when rich organic substrate Was supplied with appropriate hydraulic retention time.
