Abstract

PURPOSE: The means of making the action of anaerobes active by forming the soil near the ground surface where carbon source can be supplied to lump structure and treating the nitrogen in waste water through the denitrification action of these microbes.
CONSTITUTION: In the pebble layers 3 buried in soil, the nitrogen in waste water is made to nitric acid by soil microbes. This nitric acid is reduced to nitrogen gas by anaerobes while carbon sources are being supplied under the anaerobic conditions in the lump soil 6.
