Three-level separating biogas slurry drip-irrigation fertilization system

Abstract

The invention discloses a three-level separating biogas slurry drip-irrigation fertilization system, which comprises a biogas slurry chamber, a biogas slurry pretreatment pool and a drip-irrigation device, wherein the inner part of the biogas slurry pretreatment pool adopts a sequentially-reduced three-level step structure, the highest step plane is set as a primary sedimentation area, the middle step plane is set as a secondary sedimentation area, and the lowest step plane is set as a tertiary sedimentation area; the liquid inlet of the biogas slurry pretreatment pool is arranged in the range of the primary sedimentation area, and the liquid outlet of the biogas slurry pretreatment pool is arranged in the range of the tertiary sedimentation area; the biogas slurry chamber is communicated with the liquid inlet of the biogas slurry pretreatment pool through a liquid inlet pipeline; and the drip-irrigation device is communicated with liquid outlet of the biogas slurry pretreatment pool through a liquid outlet pipeline. The three-level separating biogas slurry drip-irrigation fertilization system can effectively filter biogas slurry for a long term with one-time economic investment, reduces the use cost of the biogas slurry, and is beneficial to the popularization of biogas slurry drip-irrigation.

Description

technical field [0001] The invention relates to a biogas slurry drip irrigation and fertilization system, in particular to a three-stage separated biogas slurry drip irrigation and fertilization system. Background technique [0002] Biogas slurry is a well-known bio-organic fertilizer with both quick-acting and long-acting properties. It can not only completely replace chemical fertilizers, but is also the best fertilizer for producing organic food. Biogas slurry is rich in nitrogen, phosphorus, potassium, various amino acids, vitamins, proteins, gibberellins, auxins, sugars, nucleic acids, and antibiotics, as well as active resistant substances such as butyric acid, indole acetic acid, and vitamin B12 , so it has a dual role of promoting crop growth and controlling disease occurrence. [0003] Biogas slurry is used as foliar fertilizer, which can regulate crop production metabolism, supplement nutrition, promote growth balance, and enhance photosynthesis; when applied to v...

AI Technical Summary

Problems solved by technology

[0004] However, currently biogas slurry is used as foliar fertilizer and drip irrigation fertilizer, and there is a clogging problem that is difficult to solve. The more effective filtering equipment for biogas slurry on the market is expensive, while the cheap filter screen has poor filtering effect and needs to be updated frequently. This has greatly affected the promotion of biogas slurry for foliar fertilizer and drip irrigation fertilizer
