Abstract

The invention discloses a device for preparing biogas by continuous treatment of straw and livestock and poultry feces and a biogas preparation method. The device comprises a sedimentation desanding pool, a straw silage pool, a pre-hydrolysis balancing pool, a feed buffer tank and an anaerobic fermentation tank. The sedimentation desanding pool and the straw silage pool are connected to the pre-hydrolysis balancing pool; the pre-hydrolysis balancing pool is connected to the feed buffer tank; the feed buffer tank is connected to a feeding port of the anaerobic fermentation tank, a discharging port at the bottom of the anaerobic fermentation tank is connected to the pre-hydrolysis balancing pool, and the top of the anaerobic fermentation tank is provided with a biogas outlet; the anaerobic fermentation tank is equally divided into 4 small compartments by inclined accelerating guide plates. The device for preparing the biogas by continuous treatment of the straw and livestock and poultryfeces cooperates with the biogas preparation method; after the straw and the livestock and poultry feces with backflow biogas slurry are subjected to reasonable carbon, nitrogen and phosphorus proportioning, the volume biogas production rate is high, the methane content of the biogas is high, and the biogas slurry treatment load is reduced.

Description

technical field [0001] The invention belongs to the field of straw treatment, in particular to a device for continuously treating straw and livestock and poultry manure to prepare biogas and a method for preparing biogas. Background technique [0002] my country is a country with a relative shortage of energy, and it is also a country with a large amount of biomass resources. According to statistics, the total annual production of crop straw in my country is about 840 million tons, and besides being used for papermaking and feed raw materials, there are about 470 million tons of straw that can be used as energy materials; crop straw is an important organic-rich (80 %~90%) biomass resources. Large-scale livestock and poultry farming in my country produces 3.8 billion tons of feces every year (equivalent to 162 million tons of standard coal if fully converted into biogas), of which only 15% are equipped with biogas engineering and other treatment facilities; livestock and poul...
