Biofilm characteristics in biological denitrification biofilm reactors

摘要

The biological denitrification method applied to treat municipal sewage containing low levels of nitrogen compounds and contaminated groundwater is very popular. There are few studies in the literature on the treatment of industrial wastewater containing high levels of nitrogen compounds. To assess the feasibility of biofilm and immobilized cells for treating wastewater which contains high-strength nitrogen compounds, the biofilm characteristics of the biological denitrification process in attached high-growth reactors were studied.
