预均化堆放农业有机废弃物的厌氧发酵技术

沼气发酵无论是干法或湿法，就产能而言，都是效率较高的方式。在日处理量上沼气发酵较焚烧、填埋等方式较低，不能对大量的城市垃圾和农村农业废弃物进行快速处理，采用预均化堆放沼气干法发酵是解决这一难题的办法。采用堆放式沼气干法或半干半湿发酵技术可以大规模处理有机废弃物，解决农村农业废弃物量大和城市有机废弃物垃圾围城的问题。在对大量废弃的有机质原料进行堆放之初，预先把原料的pH值、CN调配和温度保持等因素进行初步控制，并预均化堆放，采用保温复膜厌氧技术是快速处理大量有机质废弃物，使其快速高效发酵产气的手段之一。沼气经过简单的提纯处理可以并入城市燃气管网，或用来发电。远离燃气管网的地方，沼气液化亦能让从业者获得可观的经济效益。 

Prehomogenization Stacked Biogas Fermentation Technology in Large Junk Dry Yards of Applications

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.
