Research and Application Progress in Anammox Process for Wastewater Treatment

Technological principles, process forms and characteristics of main functional microorganisms of anammox were described. The effect of temperature, substrate concentration, pH, DO content, organics and metal iron et al. on anammox process were summarized. The application examples of anammox process for wastewater treatment in sidestream and mainstream projects were introduced. The performance and operation parameters of the process were discussed, and the problems in application were analyzed. It considered that the realize of rapid start-up, effective inhibition of toxic substances to anaerobic ammonia-oxidizing bacteria, and improving the operation stability were the keys to the application of the process, which also need further exploration and research.
