What are the main treatment methods for farm manure?
1.Dry treatment. It means that the feces are dehydrated, which mainly includes natural drying and high-temperature rapid drying. Natural drying is the use of sunlight to dry livestock and poultry manure. High-temperature rapid drying is artificial drying by a dryer. Rotary drum dryers commonly used. It can reduce the moisture content of chicken manure from 70% to 75% to less than 8% in a short period of time, but there are secondary pollution of the odor discharged from the dryer and excessively high treatment temperature that leads to poor fertilizer efficiency.
2.Aerobic composting. Livestock manure contains a large amount of organic matter and rich nutrients such as nitrogen, phosphorus, potassium, etc., which is a valuable resource for sustainable agricultural development. Therefore, aerobic composting of manure is currently a widely used treatment method. According to the characteristics of raw materials and auxiliary materials and the required carbon-nitrogen ratio and moisture content of the compost, the manure and auxiliary materials are mixed in a certain proportion, and the oxygen and temperature in the pile are appropriately controlled by compost turner to make the manure quickly ferment to produce organic fertilizer. The advantages of this method of manure treatment are that the product has less odor and it is easy to package and apply.
We have different types of compost turner for the fermentation of organic waste, which mainly includes groove type, moving type, crawler type, wheel type and fermentation cylinder. They are widely used in the organic fertilizer plant, compound fertilizer plant, sludge and garbage plant and so on. Welcome to contact us for details.
