Technical Field

[0001] The utility model belongs to the technical field of fertilizer manufacturing equipment, and in particular relates to a biogas water and fertilizer integrated comprehensive utilization system. Background Art

[0002] Biogas slurry is a common and typical raw material for high-quality liquid fertilizer. It contains rich activity, resistance and a large number of nutrients, which can be directly absorbed by crops, participate in photosynthesis and ultimately promote crop growth. The simple application of biogas slurry cannot meet the nutrient needs of crops throughout the entire growth cycle. Usually, a certain proportion of other organic fertilizers are added in agricultural production to increase the nutrient content of biogas slurry fertilizer. However, the artificial biogas fertilizer mixing method is inefficient and labor-intensive, and cannot meet the large-scale fertilization needs of large-scale agricultural production.

[0003] The applicant's main projects include fruit, grain, potato, fruit and vegetable planting. In order to better implement the new ecological circular agriculture pattern of "planting-breeding-biogas-energy", the applicant has independently explored and developed an integrated utilization project of biogas, water and fertilizer.
