Embodiment 1

[0073] The aerobic fermentation resource treatment process of chicken manure in cages is to mix wet chicken manure and auxiliary materials (straw) at a ratio of 8:2 (that is, chicken manure with 80% weight contains 75% water and straw with 20% weight contains 15% water). The material machine is fully mixed into raw materials with a water content of 55%-65%, and is transported to the container bioreactor by a belt conveyor for aerobic fermentation. Fertilizer (C / N ratio 25-35). The process adopts a pure natural process, no external heating source, no odor release, continuous dynamic, practical operation, low energy consumption, large-scale and automatic production. Its steps:

[0074] 1. Fully mix the wet chicken manure and straw with a mixer at a ratio of 8:2 to form a fermentation raw material with a water content of 55%-65%.

[0075] 2. The fermented raw materials with water content of 50%-65% are transported to the container bioreactor through the belt conveyor for aerobi...

Embodiment 2

[0078] The aerobic fermentation resource treatment process of chicken manure in cages is to use wet chicken manure and auxiliary materials (sawdust, miscellaneous branches) in a ratio of 7.5:1:1 (that is, chicken manure with 80% weight contains 75% water and 10% weight is crushed) Sawdust with 10% water content, 10% by weight miscellaneous tree branches with 15% water content) are fully mixed with a mixer to form raw materials with a water content of 50%-65%, and are transported to the container bioreactor by a belt conveyor for aerobic fermentation. After 3 days of high-temperature aerobic fermentation treatment, it is transformed into an organic fertilizer with a water content of 45% (C / N ratio 25-35). The process adopts a pure natural process, no external heating source, no odor release, continuous dynamic, practical operation, low energy consumption, large-scale and automatic production. Its steps:

[0079] 1. Fully mix the wet chicken manure and straw with a mixer at a r...

Abstract

The invention discloses a livestock excrement aerobic fermentation treatment system and a continuous treatment method. The livestock excrement aerobic fermentation treatment system comprises a mixingmachine, a container solid bioreactor and an aging drying machine, wherein the container solid bioreactor comprises a cylinder; the rotating cylinder is transversely arranged; the two ends of the cylinder are respectively connected with a fixed end cover in a moving matching manner; a feeding hole is formed in the feeding end of the fixed end cover on a feeding side; a discharge hole is formed inthe discharge end of the fixed end cover on a discharge side; the cylinder is horizontally arranged; the feeding hole is higher than the discharge hole; a guide structure for driving a material to move to the discharge end from the feeding end is arranged inside the cylinder; a fan and a circulation pipeline connected with the fan are mounted on the fixed end cover; the air outlet of the circulation pipeline is communicated with the inner cavity of the cylinder. By adopting the system, pollution can be reduced, in addition, the system is short in aerobic fermentation treatment time and good intreatment effect.

Description

technical field [0001] The invention relates to an aerobic fermentation treatment system and continuous treatment method of poultry manure, and belongs to the technical field of resource utilization of poultry manure converted into fertilizer. Background technique [0002] There is a long history of raising chickens in large-scale cages, and the amount of chickens raised is very large. Chicken farms produce a steady stream of chicken manure every day, which is a valuable raw material for organic fertilizers. However, if it is not handled properly, it will form pollution. Caged chicken manure is relatively wet and smelly, and the traditional composting process has environmental pollution problems. And the processing time is relatively long, and the effect is not good. [0003] In addition, the above-mentioned problems also exist in the manure treatment of poultry and livestock raised in other cages similar to raising chickens. [0004] Chinese invention patent application...
