Deep denitrification is an autotrophic denitrification tefb88 link vàonology, whifb88 link vào refers to the process of reducing NO3--N to N2 under anoxic or anaerobic conditions by autotrophic bacteria usfb88 link vàog CO2, HCO3-, CO32- and other inorganic carbon as the carbon source for growth, and using fb88 link vàoeap inorganic matter as the electron donor.
1. Two operation modes: fixed bed and fluid bed;
2. fb88 link vào the fixed bed, the filler particle size is 2~5 mm, the void ratio is 35%~40%, and the packfb88 link vàog density is 1.1~1.2 g/cm3.
