Abstract

The invention discloses a method for comprehensively utilizing wastes in a large-scale farm. A bottom plate with a hollow structure and a collecting bin are arranged, so that excrement and urine of livestock in a farm and wastewater for flushing the farm can be timely and effectively thrown into a biogas digester, and biogas generated by the biogas digester can be used for generating power and supplying heat. A biogas boiler and a gas generator set can generate waste gas in heat supplying and power generation processes, and waste heat carried by the waste gas is recycled and used for heating the biogas digester, so that the biogas yield and rate can be increased, and operation of the biogas boiler and the gas generator set is also facilitated. Waste heat of biogas engineering is utilized,energy loss is reduced, environmental pollution is reduced, and the comprehensive utilization rate of energy is increased. Biogas slurry generated by the biogas digester is conveyed to orchards and vegetable gardens around the farm to serve as base fertilizer, and biogas residues are conveyed to an organic fertilizer manufacturing system, so that the comprehensive utilization rates of the biogas,the biogas slurry and the biogas residues are increased.

Description

technical field [0001] The invention relates to the field of biogas utilization, in particular to a method for comprehensive utilization of large-scale farm waste. Background technique [0002] Breeding is an important industry for rural development in my country; in recent years, with the continuous expansion of breeding scale, a large number of livestock and poultry feces and sewage have become a source of pollution; the discharge of feces from farms has caused pollution of surface water, groundwater, soil and ambient air Serious pollution has directly affected people's health, and untreated manure contains a large amount of pollutants. If such organic wastewater is directly discharged or washed into rivers, lakes and reservoirs with rainwater, a large amount of dissolved oxygen in the water body will be consumed, causing The water body becomes black and smelly, causing water pollution. [0003] In order to solve the above problems, the application of biogas digesters was b...
