Abstract

PURPOSE: To improve treatment efficiency of a trickling filter by constituting a denitrifying section having a raw water inflow section as an immersion filter maintaining an anaerobic state, and a nitrifying section having a treated water outflow section as a trickling filter maintaining an aerobic state.
CONSTITUTION: Raw water 21 contg. BOD and ammonia nitrogen flows into a denitrifying section 22 by an anaerobic immersion filter. Gravel, plastic modules and the like are usable for filter media 23, and it is important to immerse the media 23 under the water surface. Besides the raw water 21, nitrified water 24 flows into the section 22, and the NO2-N and the like in this are reduced away to gaseous nitrogen 33' by the denitrifying gers stuck on the media 23. Denitrified water 25 is sprayed from the spray nozzles 18 of a nitrifying section 27, and flows down in a filter bed 29. At this time, the NH4-N in the water 25 is effetively nitrified by the nitrifying germs existing on the filter medium surfaces of the filter bed 29.
