Abstract: Biogas fermented dry or wet law both productivity is a high efficiency way.But Its daily processing capacity is lower than burn and landfill.It can not be used in rapidly processing large city garbage and countryside agriculture.Using prehomogenization stacked biogas dry fermentation is the way to solve this problem.On a lot of junk pile of organic raw materials in the beginning，advance the ingredients pH value，CN deployment，and temperature is kept in a preliminary control and prehomogenization piled up is to make rapid processing organic wastes and quickly and efficiently ferment produce gas meanses.Biogas passes simple purification processing can merge into the city gas pipeline，or used to generate electricity.Far from gas network place biogas liquefaction also can let practitioners get considerable economic effect.
