Abstract:

Investigations on dynamics of phosphorus and nitrogen reduction in the UCT model systemwere conducted. After three-week adaptation period, population of activated sludge microorganisms indicated capacity for excessive phosphorus uptake. Source of c^bon in syntheticnutrient medium was then sodium acetate (0,5 g/1), the concentration of PO4 — 30 mg/1 andthe NH4 concentration — 60 mg/1.At the second stage of the studies the PO4 concentration was 15 mg/1 in inflow, withincreased up to 40 mg/1 under anaerobic conditions and decreased to 0,5- 1,5 mg/1 underaerobic conditions. Together with conversions of phosphorus compounds, nitrification processesoccurred under aerobic conditions (12,10-23,15 mg/1) and denitrification in an anoxic reactor(0,1 -9,5 mg/1). Intensity of the phosphorus and nitrogen conversions depended upon biomassloading, degree of recirculation and retention times in the reactors.
