The traditional fermentation method of breeding manure is compost, which can be divided into strip compost and organic manure fermentation and tank compost. Both kinds of compost can handle livestock and poultry manure well. However, during the process of decomposing organic matter, a large amount of CO2, NH3, CH4, N2O and other polluting gases will be released, causing the loss of carbon and nitrogen and other nutrients in the form of gas and causing environmental pollution. With the gradual improvement of the requirements of the state on the environmental assessment of farms, the requirements of implementing the Rural Revitalization Plan and building a beautiful China, the requirements of improving the rural living environment and building an ecologically suitable village proposed in the report of the 19th National Congress of the Communist Party of China, more and more farms and fecal sewage treatment equipment manufacturers began to develop and produce fecal sewage fermentation tanks.
The general production process of organic fertilizer equipment in the combination of planting and breeding mode includes: solid-liquid separation, solid feces fermentation, and liquid feces oxidation pond treatment. The main equipment of the organic fertilizer processing process is a solid-liquid separator, a mixer, and a overturning device.
It is determined according to local climate conditions and fertilization season. When the crop fertilizing season comes, the farmers will pull back and fertilize the farmland, which is a good way to use cow dung. But the cow urine sewage can not be used. The facilities and equipment used are open fields, transportation machinery, etc.
The automatic material receiving part is that the sludge in the fermentation chamber falls layer by layer under the action of the main shaft and gravity, and is discharged after the fermentation. The fermented materials are sold as organic fertilizer raw materials to realize resource utilization.
