Abstract: This study introduced the combination, characteristics and research progress of partial nitritation-anammox. Partial nitritation-anammox process and traditional biological denitrification process were compared in nitrogen removal rate, energy consumption and carbon source. Although partial nitritation-anammox process doesn't require organic carbon, its energy consumption is higher than traditional biological denitrification process due to heating and aeration. The difference between nitrogen removal rate of partial nitritation-anammox and traditional biological denitrification process is not significant. Carbon to nitrogen ratio of wastewater needs to be considered when choosing denitrification process. Traditional biological denitrification process is more suitable for high carbon to nitrogen ratio, and combined process is more suitable for low carbon to nitrogen ratio.
