Rapid achievement of nitrification in CSTR and SBR treating reject water at high ammonia levels

Popis výsledku v původním jazyce

The ability of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) to carry out nitrification in an environment with high ammonia levels was evaluated. It was proved that nitrification could be initiated even without any inoculation of nitrifying biomass. Free ammonia (FA) strongly inhibited nitrifying bacteria during the initial phase of reactor operation. Consequently, free nitrous acid (FNA) supported NOB inhibition after the initiation of AOB activity. High AOB, as well as NOB, activity was observed even during the first day of the operation in a completely stirred tank reactor (CSTR) as well as a sequencing batch reactor (SBR) inoculated with common activated sludge at a zero initial total ammonium nitrogen concentration. It was proved that temporary inhibition of NOB activity induced by FA may lead to the permanent transformation of standard nitrification into shortcut nitrification in SBRs.
