Chapter 27. Is concentration of Dissolved Oxygen a Good Indicator od Processes in Filtration Beds of Horizontal-Flow Constructed wetlands?

Popis výsledku v původním jazyce

Filtration beds of sub-surface horizontal-flow constructed wetlands (HF CWs) are generally considered as anoxic or anaerobic and, therefore it is assumed that the outflow concentration of dissolved oxygen (DO) is usually very low. The experiments focusedon nitrification and sulfate-reduction as processes occurring under strictly aerobic and anaerobic conditions, respectively. The data revealed that in systems with very low outflow concentrations of DO nitrification was frequently very limited but in some systems a substantial reduction of ammonia occurred. On the other hand several systems with relatively high O2 outflow concentrations provided nearly zero removal of ammonia. The similar unanimous results were observed for sulfate, i.e. high O2 outflow concentrations were sometimes connected with high reduction of sulfate and on the other hand low O2 outflow concentrations were not connected with sulfate reduction. It was concluded that DO concentration at the outflow from HF CWs
