Abstract
Zgłoszenie ujawnia sposób poprawy efektywności procesu denitryfikacji przez dawkowanie dodatkowego źródła węgla polegający na tym, że związki organiczne są produkowane z osadu nadmiernego w wyniku dezintegracji kwasem azotowym (III), przy czym stężenie kwasu w reaktorze utrzymuje się w zakresie od 0 - 6 gN-HNO2/m3 i przy pH równym od 5 - 7, a cały proces trwa od 24 do 48 godzin, a następnie dawkowane w postaci cieczy uzyskanej w procesie odwadniania z zagospodarowaniem pozostałego osadu do produkcji biogazu w fermentacji metanowej.
