Research Progress of Preservation and Reactivation of Anaerobic Ammonium Oxidation Bacteria

The current preservation and activity recovery of anaerobic ammonia oxidation(ANAMMOX) bacteria were summarized, and compared the advantages and disadvantages of various preservation and recovery processes, the effects of storage time, temperature, protectant and substrate matrix on the bacteria groups were summarized. In addition, the effects of temperature, substrate matrix, reactor type and external conditions on the recovery of bacterial activity were clarified. At the same time, the main changes of microorganisms during preservation and activity recovery were analyzed. It considered that the preservation and activity recovery technology of all kinds of functional bacteria should be perfected through the research of joint preservation and activity recovery of ANAMMOX bacteria and other functional bacteria;the functional bacteria with strong resistance to hunger and fast activity recovery rate should be screened and developed;Based on the physiological properties of ANAMMOX bacteria and other functional bacteria, an online monitoring and control system can be established to control the actual operation of the process, to realize ammonia-nitrogen wastewater treatment with low energy consumption.
