Embodiment 1

[0008] Embodiment 1, (1) regulate moisture: fresh pig manure and dry material (dry pig manure or straw powder after pulverizing etc.) are stirred in mixer by a certain ratio, mix uniformly, and the discharge moisture reaches 55~60%, The ratio of dry material and fresh pig manure depends on the moisture content of fresh pig manure. (2) Breeding earthworms: pile pig manure with a moisture content of 55 to 60% on the earthworm bed, put in earthworm seeds, and breed earthworms. Put 1 kg of earthworm seeds per 10 square meters of area, and wait for 70 to 90 days for the earthworms to multiply and grow. After the large maturity, take out the earthworms, replace the earthworm manure, leave a small amount of earthworms to plant on the earthworm bed, add pig manure to continue to breed earthworms. (3) Feed: Dried earthworms, as raw materials, are added in a certain proportion to the feed base material to make high-protein feed, and the proportion of added earthworms is determined accor...

Embodiment 2

[0009] Embodiment 2, (1) regulate moisture: fresh pig manure and dry pig manure are stirred in the blender according to a certain ratio, mix evenly, and the discharge moisture reaches 55~60%, the ratio of adding dry pig manure is according to the water content of fresh pig manure rate depends. (2) Fermentation: build a fermentation tank in a fermentation greenhouse covered with a plastic film, and carry out continuous aerobic fermentation in the fermentation tank for pig manure. The fermentation cycle is 5 to 7 days. Pig manure enters from the entrance of the fermentation greenhouse and is discharged from the exit. Continuous feed and continuous discharge, install an automatic turning machine on the fermentation tank, turn over the pig manure every 2 hours, and inject fresh air into the greenhouse at the same time. (3) Drying: The pig manure is dried with an air dryer, and the drying is continuous feeding and continuous discharging. After drying, the moisture content of the pi...

Abstract

The invention discloses a method for treating and utilizing pig manure, which comprises: 1. a step of adjustment of the moisture, which is to stir and mix fresh pig manure and dried pig manure until the water content is reduced to between 55 and 60 percent; 2. a step of cultivation of earthworms, which is to stack the pig manure on an earthworm bed and throw the earthworms into an earthworm bed for breeding of the earthworms; 3. a step of preparation of feedstuffs, which is to dry and add the earthworms into feedstuff substrates to prepare high-protein feedstuffs; 4. a step of fermentation, which is to perform continuous aerobic fermentation treatment on the pig manure in a fermented greenhouse for 5 to 7 days, and turn over the pig manure for once per 2 hours, and simultaneously inject fresh air into the fermented greenhouse until the water content is reduced to between 40 and 45 percent; 5. a step of drying, which is to dry the pig manure in a pneumatic drier until the water content is reduced to less than 14 percent; 6. a step of deodorization treatment, which is to perform deodorization treatment on tail gas through a water bath dust remover; and 7. a step of preparation of edible fungus substrates, which is to add the pig manure into filler such as straw knots and wheat straw knots to prepare the substrates for cultivating edible fungi. The method has the advantages of low cost and reduction of environmental pollution due to preparation of the high-protein feedstuffs and the edible fungus substrates after the pig manure is treated.

Description

technical field [0001] The invention relates to a treatment and utilization method of livestock and poultry manure in a farm, in particular to a treatment and utilization method of pig manure. Background technique [0002] Pig manure contains a large amount of nitrogen, phosphorus, potassium and organic matter such as protein and fat, and is an excellent organic fertilizer. With the extensive implementation of intensive pig farming, a large amount of pig manure is concentrated in pig farms. Due to the high water content of pig manure, it is not easy to store and has a strong odor. The traditional treatment method is to transport pig manure to farmland for return to the field. , requires a lot of manpower and material resources, the transportation distance is large, the cost is high, and a large amount of pig manure cannot be processed in time, causing environmental pollution and affecting the health of people and animals. Contents of the invention [0003] The purpose of ...
