The traditional denitrification technology has been widely used in sewage treatment plants, but it has problems such as large equipment area, complex operation and high initial construction investment. In recent years, with the discovery of heterotrophic nitrification-aerobic denitrification (HN-AD) strains, new sewage denitrification technology has been gradually developed. HN-AD strains can achieve complete denitrification in the same reactor under aerobic conditions, thereby reducing the reactor area and simplifying the operation process. At the same time, HN-AD strains have advantages such as fast reproduction speed and strong shock load resistance, providing a potential solution for the problems in traditional sewage treatment and having a broad application prospect.
