Abstract
In this study, the laboratory scale reactor was operated for high strength ammonium nitrogen in anaerobic digestion supernatant and piggery wastewater through nitritation that is an innovative process of nitrogen removal. From the laboratory scale reactor for about 970 days, a stable nitritation was induced, and the operation factor of induced was analysed nitritation. As a result, a stable nitritation could be successfully induced from anaerobic digestion supernatant and piggery wastewaters. It appeared that nitritation wasn't affected seriously within the range of pH, Alkalinity and COD in influent. In case of SRT, it found that nitrite conversion rate was changed according to SRT condition change, so it showed that SRT had effected on nitritation. In addition,compared to ammonium nitrogen removal, it clearly revealed that nitrite conversion rates more sensitive to SRT. The conclusion in this study, it could be used as an important data when applying nitritation to municipal wastewater treatment plants(MWTPs).
