Embodiment Construction

[0030] Such as figure 1 As shown, it represents the schematic diagram of the actual application of the entire biogas slurry drip irrigation and fertilization system. The biogas slurry sedimentation tank 1 is equipped with biogas slurry raw liquid that has not been filtered by the filter device. The equipment room is equipped with a filter device 2. Biogas slurry sedimentation tank 1 Connect to the biogas slurry filter 4 in the filter device 2 through the biogas slurry delivery pipeline, the filter device 2 also includes a water filter 5, the water filter 5 is connected to the water supply pipeline, and the well water or Clean water such as river water is supplied to the water filter 5 . The outlet of the filtering device 2 is connected with the drip irrigation device 3 through a pipeline.

[0031] As the drip irrigation device 3, what is exemplified here is a common agricultural drip irrigation device. This drip irrigation device consists of a delivery main pipe, a plurality ...

Abstract

The invention provides a biogas slurry fertigation system, which can effectively utilize biogas slurry as an organic liquid fertilizer, thus realizing reclamation of waste and performing aftermanuring on organic crops. The fertigation system comprises a biogas slurry sedimentation tank, a filter and a drip irrigation device, wherein the biogas slurry sedimentation tank is filled with unfiltered biogas slurry stock solution; the filter is composed of a biogas slurry filter and a water filter; and biogas residue in the biogas slurry stock solution in the biogas slurry sedimentation tank sedimentates at the bottom part of the biogas slurry sedimentation tank, a water pump is used to feed the biogas slurry after sedimentation to the biogas slurry filter for filtering via a delivery pipeline, solid matters capable of blocking the drip irrigation device in the biogas slurry are filtered out, and the filtered biogas slurry and the clean water which is obtained after being filtered by the water filter and can not cause the blockage of the drip irrigation device are mixed at a required ratio and then fed in the drip irrigation device to perform drip irrigation on the crops.

Description

technical field [0001] The invention relates to a biogas slurry drip irrigation and fertilization system. Background technique [0002] With the further development of human beings and society, the demand for energy has increased sharply, and the awareness of protecting the earth has been increasing. People have begun to develop and use new energy and renewable energy. As a new renewable energy, biogas has been widely used and promoted in rural areas of our country. , but also brings corresponding problems. [0003] Generally, biogas is produced by fermentation. The raw materials mainly include plant residues and animal manure. [0004] Biogas slurry contains various amino acids, vitamins, proteins, gibberellins, auxins, sugars, nucleic acids, and antibiotics. Among them, gibberellins can make seeds germinate early; nucleic acids and monosaccharides can enhance the drought resistance of crops; free amino acids can enhance the frost resistance of crops; antibiotics can prev...
