Nitrification in a completely stirred tank reactor treating the liquid phase of digestate: The way towards rational use of nitrogen

Popis výsledku v původním jazyce

The nitrification of the liquid phase of digestate was conducted using completely stirred tank reactor (CSTR). The possibility of minimizing nitrogen losses during the application of LPD to the soil as well as during long-term storage or thermal thickening of LPD using nitrification was discussed. Moreover, the feasibility of applying the nitrification of LPD to the production of electron acceptors for biological desulfurization of biogas was assessed. Nitrification was confirmed immediately after the start-up of the CSTR. On the other hand, working without pH control was a risk because of the free nitrous acid inhibition towards nitrite oxidizing bacteria resulting in massive nitrite accumulation. The control of pH at 7,0 resulted in nitrogen oxidation efficiency reaching 98,3 +- 1,5% and the presence of N-NO3- among oxidised nitrogen 99,6 +- 0,4%. Optimum characteristics of the tested system were gained in this phase of reactor operation.
