Abstract
Przedmiotem zgłoszenia jest sposób inhibicji rozwoju bakterii nitryfikacyjnych 2-fazy w procesie nitrytacji, znajdujący zastosowanie w oczyszczalniach ścieków. Sposób charakteryzuje się tym, że strumień osadu recyrkulowanego w ilości 10% - 25% zawierający bakterie nitryfikacyjne 2-giej fazy przepływa przez selektor, do którego dodaje się kwas azotowy (III) o zawartości azotyn o stężeniu 200 — 1000 gN/m3 i kwas siarkowy lub kwas solny w celu regulacji pH do 5-7, a następnie osad recyrkulowany z selektora przepływa do układu komory osadu czynnego z osadnikiem wtórnym.
