The Development of Nitrogen Treatment Technology by Coupling Methanogenesis and Anammox in ASBR
Main Article Content
Abstract
This research is to study of ammonia- nitrogen treatment in wastewater by coupling Anaerobic
Ammonium Oxidation (Anammox) and Methanogenesis in ASBR. The aims were to study of
efficiency and addition of anaerobic ammonia- nitrogen treatment by using a model of anaerobic
sequencing batch reactor with 24 L working volume, 20,000 mg/lMLVSSand 50 rounds/min completely stirring. The control variation is the COD concentration of 1,000 mg/l in synthetic wastewater and at 72 hours hydraulic retention time. The independent variation was the nitrite concentration for study of nitrite appropriate concentration that added in wastewater and to study of synthetic wastewater hydrolysis. The results showed that ASBR efficiency of COD removal is more than 90% and ammonia- nitrogen removal is more than 50%. This study showed that ASBR removed organic wastewater, COD and ammonia - nitrogen, in single reactor. Therefore this study was the development of wastewater treatment technology which has Methanogenic bacteria and Anammox bacteria in single reactor.
