[0003] Biological denitrification of nitrogen-containing wastewater utilizes the metabolic activity of microorganisms to convert nitrogen compounds (such as ammonia nitrogen, nitrate nitrogen, and nitrite nitrogen) in the wastewater into nitrogen gas (N2) and release it into the atmosphere, thereby removing nitrogen.
