Sulfide and ammonium oxidation, acetate mineralization by denitrification in a multipurpose UASB reactor
The physiological and kinetic behavior of a denitrifying granular sludge exposed to different sulfide loading rates (55–295mg/Ld) were evaluated in a UASB reactor fed with acetate, ammonium and nitrate. At any sulfide loading rates, the consumption efficiencies of sulfide, acetate and ammonium were...

description | The physiological and kinetic behavior of a denitrifying granular sludge exposed to different sulfide loading rates (55–295mg/Ld) were evaluated in a UASB reactor fed with acetate, ammonium and nitrate. At any sulfide loading rates, the consumption efficiencies of sulfide, acetate and ammonium were above 95%, while nitrate consumption efficiencies were around 62–72%. At the highest sulfide loading rate the ammonium was used as electron donor for N2 production. The increase of sulfide loading rate also affected the fate of sulfide oxidation, since elemental sulfur was the main end product instead of sulfate. However, the lithotrophic denitrifying kinetic was not affected. FISH oligonucleotide probes for Thiobacillus denitrificans, Thiomiscropira denitrificans, genus Paracoccus and Pseudomonas spp. were used to follow the microbial ecology. The results of this work have shown that four pollutants could simultaneously be removed, namely, sulfide, ammonium, acetate and nitrate under well defined denitrifying conditions. |
