Organic Wastewater

The combined partial nitrification/Anammox process is especially suitable for the treatment of influents with low C/N ratio. However, many nitrogenous wastewater are also rich in organics. Two systems (continuous stirred-tank reactor (CSTR) and sequencing batch reactor (SBR)) are commonly used to achieve nitrite accumulation, but no complete comparison between these two systems for treating different wastewater has been reported. The objective of this paper was to compare the partial nitrification in CSTR and SBR for the treatment of ammonium-rich organic wastewater. The result showed that it took a shorter time to startup partial nitrification in CSTR, but SBR was a better option for treating ammonium-rich organic wastewater with C/N lower than 0.34. With increase HRT to 48 h, excellent nitrite accumulation could be achieved in both reactors for wastewater containing landfill leachate. For subsequent anammox, CSTR was more suitable when leachate percentage ranged from 35% to 40%.
