<p><P>PROBLEM TO BE SOLVED: To provide a low-cost and efficient anaerobic hydrogen fermentation treatment system. <P>SOLUTION: The anaerobic hydrogen fermentation treatment system comprises a hydrogen fermentation tank, an ammonia-containing material generator, and a denitrification tank, and organic waste is moved and treated in this order to discharge the treated wastewater from the denitrification tank. A part of ammonia-containing material from the ammonia-containing material generator is circulated/supplied to the hydrogen fermentation tank to promote hydrogen fermentation. A part or the whole of hydrogen fermentation gas generated by the anaerobic fermentation of the organic waste in the hydrogen fermentation tank is supplied to the denitrification tank to reduce the amounts of nitrogen compounds, and the treated wastewater is discharged from the denitrification tank. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
