Research and Application Progress of Immobilized Denitrifying Bacteria

Immobilized microbial bacterial agent is an advanced ecological wastewater treatment technology, free microorganisms will be fixed on a specific carrier, and then slowly released, relying on the metabolic transformation of microorganisms to remove pollutants in the water, so as to achieve the purpose of purifying wastewater. This paper summarizes the strain selection, carrier optimization and fixation method of immobilized denitrifying bacteria technology, and summarizes the application of immobilized denitrifying bacteria agent in various types of wastewater treatment, and discusses the problems and improvement strategies of immobilized denitrifying bacteria agent in the practical application, so as to provide scientific reference for the development and application of immobilized bacteria agent technology.
