Title:
METHANE FERMENTATION SYSTEM AND APPARATUS FOR PRODUCING FERTILIZER USING SAME
Document Type and Number:
WIPO Patent Application WO/2010/098343
Kind Code:
A1
Abstract:
To obtain a fermentation liquor by which the problem of the pollution of underground water with nitrogen can be reduced when the fermentation liquor is applied back to a farm land as a fertilizer, disclosed is a methane fermentation system characterized by being provided with a methane fermentation tank, a heating tank for heating a fermentation liquor released from the methane fermentation tank to a temperature higher than the fermentation temperature in the methane fermentation tank, and an ammonia-removing device for removing ammonia from the fermentation liquor released from the heating tank. According to this methane fermentation system, organic nitrogen in the fermentation liquor released from the methane fermentation tank is degraded into ammonia nitrogen so that the ratio of ammonia nitrogen is increased, and ammonia is then removed by the ammonia-removing device in the following step. Thus, nitrogen in the methane fermentation liquor can be reduced.
