With the development of aquaculture, the treatment of chicken manure, duck manure and pig manure has become an important topic. The conversion of livestock and poultry manure into renewable resources plays an important role in resource conservation and environmental protection, and can promote the development of agricultural circular economy and sustainable development of animal husbandry. The harmless treatment methods of chicken manure, duck manure and pig manure are mainly high temperature composting. Organic fertilizer equipment treats manure with high water content, large volume, inconvenient transportation and use into high-efficiency organic fertilizer granules, which promotes the recovery of feces and the application of organic fertilizer in agriculture.
Chicken manure, duck manure and pig manure were composted and fermented in fermentation tank, and material was stirred by trough compost turner. Using trough compost turning machine, the organic fertilizer equipment has a large capacity, and the production conditions under the fermentation tank are easy to control. It can ensure that microorganisms have sufficient oxygen supply. Even in the case of high water content, composting fermentation can proceed smoothly, and straw can be added to raw materials to adjust water at any time. The compost turning machine has a strong ability to operate, usually once a day.
The water content of compost material is about 60%. Before fermentation, we adopt dewatering machine to dehydrate the feces, and use organic fertilizer equipment to pretreat the feces, so as to reduce straw, sawdust and other adjusting materials. Manure dewatering machine can be used to separate animal manure from waste water such as wine tank and soy sauce dregs. And the manure treated by dewatering machine can directly ferment organic fertilizer. The manure is the main fermentation material in the production of organic fertilizer, which can reduce the content of straw regulators and improve the content of organic matter. In the early stage of composting chicken manure, duck manure and pig manure, fermentation bacteria can be added. The composting temperature rises quickly and the fermentation speed is accelerated.
