A process for wastewater purification from ammonia nitrogen comprises two-stage biological treatmnent in bioreactors with immobilization nozzles, using nitrifying bacteria and anammox-bacteria. During the first stage of the purification wastewater is divided into two streams in a predetermined volume ratio. One of them is delivered into aerobic bioreactor, where it is treated by nitrifying bacteria, and the second – into the anaerobic bioreactor, where the treatment by heterotrophic anaerobic bacteria is carried out, with the further joining of the divided stream in anammox-bioreactor, where the second stage of the purification is carried out. |
