<p><P>PROBLEM TO BE SOLVED: To provide a methane fermentation waste treatment method which can reduce the amount of an added coagulant when methane fermentation waste is treated. <P>SOLUTION: In the methane fermentation waste treatment method where organic waste is subjected to methane fermentation in a methane fermentation tank, and then the methane fermentation waste after the methane fermentation is cleaned by an activated sludge method, the methane fermentation waste is subjected to aeration treatment and coagulation treatment while maintaining the temperature of the methane fermentation waste at the temperature of the inside of the methane fermentation tank, or after raising the temperature of the methane fermentation waste. In this method, the temperature of the methane fermentation waste may be maintained at the temperature of the inside of the methane fermentation tank, or may be raised higher than the temperature of the methane fermentation tank by heating the methane fermentation waste. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
