Embodiment 1

[0015] Such as figure 1 Shown:

[0016] A. Transport poultry manure or sludge (raw materials) to the drying yard separately, spread them evenly to dry, and turn over the dried raw materials every 2-3 days, which is conducive to the evaporation of water in the raw materials. Make the moisture content of the raw materials reach 50-60%, and the particle size is 10-80mm. Too thick is not conducive to improving the compost maturity, and too fine is not conducive to ventilation and ventilation, which affects the improvement of compost temperature.

[0017] B, the poultry manure and sludge that water content is 50-60% are mixed by the weight and number ratio of 10: 2;

[0018] ① If the water content is too high > 60%, it should be prepared by adding a conditioning agent; the conditioning agent is dried organic agricultural and sideline products such as crushed dry rice straw, dry rice bran, dried cow dung, and crushed hay;

[0019] ② If the water content is too low < 40%, sewage, s...

Abstract

The present invention relates to harmless fowl and livestock feces resource processing and utilizing technology, and aims at solving the pollution problem caused by direct drainage of fowl and livestock feces in low cost and small covered area. The processing and utilizing process includes mixing fowl and livestock feces as main material and amendment, adding compost degrading agent; aerobic high temperature degradation through stacking, turning and stacking; lowering the temperature to normal temperature, and drying in the air or in the sun. The present invention has advantage of low production cost and reduced environmental pollution, and the product has rich nutritive components, can reduce soil hardening, is favorable to maintaining water and fertilizer, ventilating and promoting root system development.

Description

Technical field: [0001] The invention relates to a technology for treating manure in animal husbandry, in particular to a technology for harmless resource utilization of poultry manure. Background technique: [0002] The stench, eutrophication of water bodies, and the spread of "zoonotic" diseases caused by the feces and sewage produced by intensive livestock and poultry farming have aroused great concern. However, for the treatment of farm sewage, there is still a lack of technology generally accepted by farmers, and the treatment of this type of wastewater is very difficult. Most of the existing animal husbandry farms discharge poultry manure directly into ponds or rivers, and these polluted water sources wash into the river with rainwater during the flood season, causing serious pollution to surface water, groundwater, soil and air, and causing The eutrophication of water bodies and endangering the health of livestock and poultry itself and human body are the main reasons...
