The invention relates to a livestock and poultry excrement resource utilization system which comprises a livestock and poultry excrement gathering pool, an adjusting device, a sludge pump, a centrifugal machine, a solid treatment tank, a liquid sewage reactor, a gas holder and a liquid storage pool. The adjusting device is used for adding an adjusting substance into the livestock and poultry excrement gathering pool; a bottom outlet of the livestock and poultry excrement gathering pool is communicated with a feeding port of the centrifugal machine through the sludge pump, a discharging port ofthe centrifugal machine is connected with a feeding port of the solid treatment tank through a first conveyor, and the solid treatment tank is used for conducting drying, high-temperature fermentation and sterilization treatment on materials separated out by the centrifugal machine so as to obtain solid livestock and poultry excrement; a liquid outlet of the centrifugal machine is communicated with a water inlet in the bottom of the liquid sewage reactor, a gas-water separator is arranged in the liquid sewage reactor, a gas outlet in the top of the liquid sewage reactor is communicated with the gas holder through a biogas pipeline, and an overflow water outlet of the liquid sewage reactor is communicated with the liquid storage pool. By means of the technical scheme, resourceful comprehensive treatment of the livestock and poultry excrement can be achieved.
Description
technical field [0001] The invention relates to the field of solid waste treatment, in particular to a resource utilization system for livestock and poultry manure. Background technique [0002] my country is a big country in the production and consumption of animal husbandry products. During the process of livestock and poultry breeding in agriculture and animal husbandry, livestock will produce a large amount of livestock and poultry manure, which will lead to air pollution, breeding of mosquitoes and flies, and a large number of long-term accumulation of livestock and poultry manure will cause harmful bacteria in the environment. The number is on the rise. Where manure is piled or flows through, a large amount of high-concentration manure seeps into the soil, which can cause plants to grow wildly or damage the root system of plants or even cause plant death. The infiltration of feces into groundwater will seriously exceed the standard of nitrate nitrogen, hardness and tot...
