Problems solved by technology

However, since the fermented waste can only be used for fertilization in greenhouses, but because excessive use of fermented waste in planting greenhouses will cause crops to be "burned to death", the utilization rate of fermented waste is not high, so most The waste cannot be processed, causing secondary pollution; in addition, in a low temperature environment, because the biogas digester cannot produce gas normally, it is easy to cause the biogas digester to stop gas, affecting the normal use of the biogas digester

Embodiment 1

[0030] Such as Figure 1-3 A comprehensive circulation system for planting, breeding, and green storage is shown, including a breeding shed 1, a planting shed 2 and a biogas tank 3, the sewage pipe 4 of the breeding shed is connected to the biogas tank 3, and also includes 5 pools of biogas slurry, an above-ground biogas tank Liquid reserve pond 20, green storage pond 19 and solid-liquid separation device 6, green storage pond 19 is arranged between the breeding shed 1 and the planting shed 2, the biogas digester 3 is arranged in the planting shed 2, and the biogas digester 3 is separated from the solid-liquid The feed port of the device 6 is connected, and the above-ground biogas slurry reservation pond 20 is connected with the liquid outlet of the solid-liquid separation device 6; the liquid outlet of the above-ground biogas liquor reservation pond 20 is connected with the infiltration irrigation system 7 The liquid inlet of the infiltration irrigation system 7 is connected ...

Embodiment 2

[0047] A comprehensive circulation system for planting, breeding, and green storage, including a breeding shed 1, a planting shed 2, and a biogas tank 3, the sewage pipe 4 of the breeding shed is connected to the biogas tank 3, and also includes 5 pools of biogas slurry, and reserved biogas slurry on the ground Pond 20, green storage pond 19 and solid-liquid separation device 6, green storage pond 19 is arranged between culture shed 1 and planting booth 2, biogas tank 3 is arranged in the planting booth 2, the connection between biogas tank 3 and solid-liquid separation device 6 The feed port is connected, and the biogas slurry reservation pond 20 on the ground is connected with the liquid outlet of the solid-liquid separation device 6; The liquid outlet of the infiltration irrigation system 7 is connected with the biogas tank 5, and the biogas tank 5 is connected with the flushing system 8 of the breeding shed 1, and the gas outlet of the biogas tank 3 is connected with the br...

Embodiment 3

[0064] A kind of comprehensive circulation system for planting, breeding, and green storage as described in Example 1, the difference is that the existing infiltration irrigation system 7 is adopted, and the hard pipe infiltration pipe 18 is adopted, and there is no filler in the pipe.

[0065] It is necessary to switch on and off the ground infiltration irrigation system 7 on a regular basis, and turning on the ground infiltration irrigation system 7 all the time will cause excessive nutrition of planted crops and affect growth. Compared with embodiment 1, labor cost is required.

[0066] After one year of actual on-site use, under the scale of breeding 100 dairy cows, 1,150 tons of forage grass is consumed every year, and 32 tons of biogas residue are produced. The biogas slurry can meet the nutrient requirements of 4 acres of greenhouses, and the agricultural products have no pesticide and fertilizer residues. The biogas residue can be sold as organic fertilizer or used as...

Abstract

The invention relates to a comprehensive circulation system and method for planting, raising and silage. The system includes a raising shed, a planting shed and a biogas digester. The sewage drainagepipeline of the raising shed is connected to the biogas digester. The system further includes a biogas liquid pond, a silage pond and a solid-liquid separation device. The silage pond is arranged between the raising shed and the planting shed, the biogas digester is connected to the feed inlet of the solid-liquid separation device, and the biogas liquid pond is connected to the liquid outlet of the solid-liquid separation device; the liquid outlet of the solid-liquid separation device is respectively connected to a seepage irrigation system of the planting shed and a flushing system of the raising shed. The outlet of the biogas digester is connected to a biogas lighting device and a biogas heating device in the raising shed and the planting shed. The comprehensive circulation system and method for planting, raising and silage overcomes the shortcoming of low utilization rate of fermented wastes in the traditional comprehensive system for planting and raising. The fermented wastes are separated into solid and liquid to obtain biogas residue and biogas liquid. The biogas liquid is utilized in the seepage irrigation system and the flushing system of the raising shed. The biogas residue can be used as organic fertilizer in other farmlands.

Description

technical field [0001] The invention relates to a comprehensive circulation system and method for planting, breeding and green storage, in particular to a comprehensive circulation system and method for planting economic crops and breeding large-scale livestock, and belongs to the technical field of ecological agriculture. Background technique [0002] With the development of social economy, sustainable development, green and environmental protection agricultural model gradually replaces the traditional agricultural model, and more and more related technologies and researches are emerging. For example, Chinese patent document CN101691822A (application number 200910023876.7) discloses a planting and breeding cycle Economic daylight and winter warming greenhouse. It consists of two sheds: sunny and shady. The sun shed is used for planting and the shady shed is used for breeding. The two sheds are arranged back to back and share a cavity. Digester for manure. Both shed worksh...
