The principle of use is shown in figure 3.
The specific operation is as follows:
1. pig house site selection
The pig house should be selected to be ventilated, shady and cool, and the topography is higher than the place in farmland (the purpose is to make natural pond liquid accessible pipeline directly flow to the farmland, reduces energy consumption, reduce cost), and the best is the place that the water resource is abundant sanitary, clean.
2. Construction of pig house
The pigsty area is constructed according to two square meters of each pig, the number of the pigs in each pigsty is 50-100, and the principle of full-in and full-out is implemented, so that the pigsty can be cleaned and disinfected, the cross infection is prevented, and the morbidity and mortality of the pigs are reduced. The pigsty is provided with a rest moving area, a feeding area, a bathing area and an excretion area which are positioned at four points, the pigsty is designed to have rest and move, the feeding, bathing and defecation are convenient, and the pigsty is convenient to clean and disinfect. The pigsty ground is inclined to the feeding area, the bathing area and the defecation area step by the rest moving area to form a slope (5 degrees), so that each pigsty has a certain height difference, the pigsty is free from water accumulation, and the pig manure is discharged into the pigsty outer pipeline in time. The pig manure discharging pipe in the pigsty has a certain inclination, and can discharge pig manure into the biogas fermentation bag in time, so that the time of exposing the pig manure in the air is shortened.
3. Setting of biogas bag
The biogas fermentation bags 100 are designed with 4 bags, the volume of the biogas fermentation bags is determined according to the pig raising quantity, a certain height difference is required to be arranged at the placement position of each biogas fermentation bag, so that biogas slurry is smoothly discharged, and a buffer fermentation bag is prepared (the problems of breakage, maintenance and the like of the fermentation bags are avoided).
