A method for culturing reactor Autotrophic denitrification granular sludge in a continuous stream

A reactor Autotrophic culture granular sludge nitrogen removal in a continuous stream to be wastewater autotrophic denitrification art. It comprises the following steps: first in a continuous flow reactor CANON biofilm inoculum, the entire process starts directly under oxygen-limited conditions autotrophic denitrification processes Autotrophic culture denitrification granular sludge. First start at low load conditions throughout the autotrophic denitrification granular sludge, sludge inoculated with the reaction conditions in the continuous flow reactor continue to adapt, the processing capacity of a continuous flow reactor continues to increase. Next, enter a high-load stage of culture, influent ammonia concentrations employed maintained constant, to shorten the way to improve HRT influent load, cultured granular sludge. Because of the continuous flow reactor with a strong water flow in the memory shearing force to promote the whole process of particles autotrophic denitrification of the sludge, the granular sludge structure formed in a continuous flow reactor the more stable.
