Abstract
It has been known that sewage containing high-concentration nitrogen affects the efficiency of municipal wastewatertreatment plants harmfully. Therefore, research has been actively conducted to treat sewage containing high-concentrationnitrogen. The current study has analyzed organic compounds, conducted foaming tests, and operated a laboratory-levelnitritation reactor with the subjects of anaerobic digester supernatant and livestock wastewater which are the typical kinds ofsewage containing high-concentration nitrogen. According to the results of analyzing organic compounds, soluble inertcomponents form the largest part of anaerobic digester supernatant while particle biodegradable components occupy the mostpart of livestock wastewater. About the retention time proper for the reaction of nitritation, anaerobic digester supernatantshows 2 days while livestock wastewater indicates 6 days. It seems that the difference in the proper retention time isresulted from the difference of properties in organic compounds and ammonium nitrogen concentration. In addition, livestockwastewater’s reactor foam is generated comparatively more than anaerobic digester supernatant’s, but it tends to beeliminated faster. It is expected that the findings of this study can be utilized as foundational data afterwards in applyingthe reaction of nitritation to municipal wastewater treatment plants.
