Fermentation: Under normal circumstances, the chicken manure produced in the chicken farm can be directly used as a crop fertilizer. However, after accumulation and fermentation, not only can the various pathogens in chicken manure be effectively killed, but also the fertility can be greatly enhanced. In particular, the chicken manure and the contaminants produced by the affected chickens should be fermented. This is a good method of treating the waste. The specific method is to regularly collect chicken excrement, bedding, etc., accumulate on the open ground (it can also pile up in a pit, but it can not collect water), and use wet mud to seal it for fermentation. The season where the temperature is higher should be accumulated for more than 2 months, and winter for more than 3 months, and then used as a fertilizer for crops. Biogas production: A chicken farm can construct a biogas digester, collect filthy water for cleaning chicken sheds and utensils into a biogas digester to produce biogas. The biogas can provide energy for the chicken farm. If the amount of biogas is insufficient, the chicken manure can be directly discharged into biogas. Pool fermentation. Biogas slurry (residue) produced by biogas fermentation is also a good fertilizer, and it can also effectively kill pathogens. Deep burial: Deep burial is the most common method of harmless treatment of dead chickens and contaminants. Choose a place that does not pollute the water source and does not affect the surrounding environment. You can also dig pits for dead chickens in open areas inside the chicken farm. The pit should have a certain depth. The bottom of the pit should be covered with a layer of quick lime. The thickness of the soil layer covered by the chicken carcass should be at least 1.5 meters. The surface and surrounding environment covered with mud should be sprayed and disinfected. Carriage of bodies and contaminants must be carried out in containers that can be hermetically closed or in a watertight, airtight transport vehicle to prevent contamination of the environment during handling.
