Influence of sulphanilamide in wastewater on Anammox process
PublikacjaBadano wpływ krótko- oraz długookresowej ekspozycji mieszanej kultury Anammox na działanie sulfonamidu. Otrzymane wyniki potwierdziły, że sulfanilamid (SA)hamuje proces Anammox. Wyższe stężenia SA powodowały silniejszy efekt inhibicji usuwania związków azotu ze ścieków. Natomiast długookresowe testy potwierdziły hipotezę, że wydłużenie czasu ekspozycji mikroorganizmów Anammox na działanie SA skutkuje obniżeniem stopnia inhibicji...
