Optimalizace procesu denitrifikace a post-denitrifikace z hlediska eliminace tvorby dusitanů a oxidů dusíku

The aim of the project is to determine the critical technological parameters of the denitrification and post-denitrification process, selection and long-term pilot verification of suitable external organic substrate that will lead to the elimination of the formation of unwanted nitrogen oxides (NOx) - significant greenhouse gases. It turns out that it is the appropriate (well biodegradable) organic substrate, its ratio to the nitrogen concentration, residence time, metabolic load and nitrate recycling that determine the complete (post-)denitrification process, i.e. the biological reduction of nitrate nitrogen, which ideally takes place down to nitrogen gas and does not produce unwanted intermediate products, i.e. nitrite and NOx. Long-term verification and detailed monitoring on a real WWTP will thus allow very valuable operational data to be obtained.
