| Outline of Final Research Achievements |
The relationship between ANAMMOX bacteria and vegetation, filter beds, wastewater feed was analyzed in order to utilize the ANAMMOX reaction in constructed wetlands. In the soil wetland, the nitrogen purification function remained high in the subsurface flow compared with the surface flow, and a different tendency was observed in the number of ANAMMOX bacteria in both flow. In a lab scale zeolite constructed wetland, ANAMMOX reaction proceeded by adsorption/re-elution of ammonia of zeolite even if the inflow concentration was changed. On the other hand, in a pilot scale zeolite constructed wetland with a constant inflow concentration, nitrification takes precedence in the filter bed, the ANAMMOX reaction did not proceed. It was likely because formation of reducing conditions due to organic matter supply from vegetation roots, restriction on the supply of substrate ammonia, etc.
