Embodiment 1

[0033] This embodiment provides an integrated fully closed-loop ecological cycle agricultural system, such as figure 1 As shown, the integrated fully closed-loop ecological cycle agricultural system includes a three-dimensional planting facility 8 built on the ground. The three-dimensional planting facility 8 in this embodiment can be any three-dimensional agricultural facility in the prior art, such as building on the ground The greenhouse above is provided with a three-dimensional frame for three-dimensional planting of crops in the greenhouse.

[0034] The agricultural system in this embodiment also includes an anaerobic fermentation subsystem arranged underground, such as figure 2 As shown, the anaerobic fermentation subsystem further includes a hydrolytic acidification tank 3 and an anaerobic fermentation tank 4 arranged in series, and the anaerobic fermentation zone 41 and pipelines and corridors 42 of the anaerobic fermentation tank 4 are all arranged underground; The a...

Embodiment 2

[0048] The integrated fully closed-loop ecological cycle agricultural system in this embodiment is the same as that in Embodiment 1, and this embodiment provides an optimized operation process of the integrated fully closed-loop ecological cycle agricultural system. The operation technique in the present embodiment comprises:

[0049] (1) Measuring the livestock and poultry manure 1 into the pretreatment tank 2, mixing it with the regulated water, and then carrying out the sedimentation and impurity removal treatment, the TS content of the livestock and poultry manure 1 in the pretreatment tank 2 after adding the regulated water is 6wt %, the pH value of the liquid in the pretreatment tank 2 is adjusted to 6.5-7.5;

[0050] Send the livestock and poultry manure 1 after sedimentation and removal of impurities together with the straw and tail vegetables 9 that have been crushed to a length of 3-5 cm into the hydrolysis acidification tank 3, and the residence time of the mixed ma...

Embodiment 3

[0056] The integrated full-closed-loop ecological cycle agricultural system in this embodiment is the same as that in Embodiment 2, and the operation process in this embodiment includes:

[0057] (1) Enter the pretreatment tank 2 after the livestock and poultry manure 1 is measured, and carry out the sedimentation and impurity removal treatment after mixing with the regulating water. The TS content of the livestock and poultry manure 1 in the pretreatment pond 2 after adding the regulating water is 5wt %, the pH value of the liquid in the pretreatment tank 2 is adjusted to 6.5-7.5;

Abstract

The invention provides an integrated full closed-loop ecological circular agriculture system. The integrated full closed-loop ecological circular agriculture system comprises a stereoscopic planting facility built on the ground, an anaerobic fermentation sub system arranged under the ground, a solid-liquid separation device, a marsh gas power generation device and a waste heat recycling device. The marsh gas power generation device is connected with the stereoscopic planting facility and used for supply power to the stereoscopic planting facility. The waste heat recycling device recycles the waste heat generated by the marsh gas generation device, and a heat output part of the waste heat recycling device is connected with a hydrolysis acidification pool and an anaerobic fermentation pool.The marsh gas generated by the agriculture system is completely used for power generation, the power energy, the waste heat and CO2 are all self utilized, and thus multi-stage utilization of energy issuccessfully achieved. The underground type anaerobic fermentation sub system is adopted, the investment cost is greatly reduced, the construction period is shortened, meanwhile, loss of heat in thewinter operation process of the project can be reduced advantageously, and the operation energy consumption of the system is reduced.

Description

technical field [0001] The invention belongs to the technical field of modern agriculture, and specifically relates to a fully closed-loop ecological cycle agricultural system that can realize the resourceful, ecological, harmless and industrialized treatment of agricultural waste such as manure and straw. Background technique [0002] At present, the total amount of livestock and poultry manure produced in my country has reached nearly 4 billion tons every year, and the chemical oxygen demand of livestock and poultry farming emissions has reached 12.68 million tons, accounting for 96% of the total emissions from agricultural sources, which is the cause of agricultural non-point source pollution. important reason. If this kind of livestock and poultry manure can be effectively disposed of and rationally utilized, it will become a valuable resource, and it will also bring opportunities for accelerating the transformation and upgrading of the livestock industry. In addition to...
