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。
Biogas fermentation, whether dry or wet, is a more efficient way of producing capacity. In the daily capacity of biogas fermentation is burned, landfill and other low, can not be a large number of urban waste and rural agricultural waste rapid processing, the use of pre-homogenization of biogas dry fermentation is the solution to this problem. The use of stacked biogas dry or semi-dry semi-wet fermentation technology can be large-scale processing of organic waste, to solve the large amount of rural agricultural waste and municipal waste around the city of organic waste problems. When a large amount of discarded organic material is piled up, preliminary control is made on factors such as raw material pH value, C / N deployment and temperature keeping, etc., and pre-homogenized and piled up. Waste, making it one of the means of rapid and efficient fermentation of gas production. Biogas after simple purification can be incorporated into the city gas pipe network, or used to generate electricity. Away from gas pipelines, biogas liquefaction also gives practitioners significant economic benefits.
