Abstract

Keksintö käsittää menetelmän ja laitteiston jäteveden puhdistamiseksi nitrifikaatio-denitrifikaatio -prosessilla. Keksinnön mukaan - tarkkaillaan ainakin säiliöstä pois johdettavan kaasun happipitoisuutta, - määritetään tarkkailusta saatujen mittaustietojen perusteella säiliössä olevan jäteveden nitrifikaatioaste,The invention comprises a method and apparatus for purifying wastewater by a nitrification-denitrification process. According to the invention - the oxygen content of at least the gas discharged from the tank is monitored, - the nitrification degree of the wastewater in the tank is determined based on the measurement data obtained from the monitoring,
