Method for producing trees and flowers special fertilizer by using anaerobic fermentation vinegar residue

Abstract

The invention relates to a method for producing trees and flowers special fertilizer by using anaerobic fermentation vinegar residues. The method comprises the flowing steps of (1) adding whitewash at the concentration of 5% in 1000kg to adjust PH to be 6.8-7.6; (2) adding baiyibao EM stock solution which is 0.3% of the 1000kg of fresh vinegar residues and corruption agent which is 0.2% of the 1000kg of fresh vinegar residues in the mixed vinegar residues, transporting the stirred vinegar residues in a fermentation tank, and conducting anaerobic digestion at the temperature of 35 DEG C for 35 days; and (3) collecting sewage gas produced by fermentation in an air storage tank, separating surplus biogas residues and biogas slurry to obtain trees and flowers special liquid fertilizer and trees and flowers special solid fertilizer produced by using the anaerobic fermentation vinegar residues. The method effectively uses the vinegar residues to produce the trees and flowers special fertilizer, saves resources, changes waste into wealth, reduces environmental pollution, improves recycling and harmless of the vinegar residues, increases peasant income through the produced special fertilizer, simultaneously achieves high-yield and high-quality high-efficiency agriculture and has wide market prospects.
