Abstract

PURPOSE: To enable the denifrification treatment simply in a low cost by introducing sewage intermittently into a granulated soil containing a carbon source.
CONSTITUTION: Onto an inclined surface 6 comprising a water impermeable layer, a soil 7 mixed with an org. carbon source 5 such as natural humus soil, org. sludge or the like and granulated is layered and, when a water supply pipe 8 such as a foraminous ceramic pipe or the like is enbedded and a sewage is intermittently supplied, because the soil near to an inclined surface is maintained in an unaerobic condition and the soil near to a soil surface in an aerobic condition, the sewage gradually blowed downwardly receives the nitration and a denitrification action mutually and exhausted in a water collecting trough 9.
