Method for treating kitchen liquid residues and organic liquid fertilizer prepared from kitchen liquid residues

Abstract

The invention discloses a method for treating kitchen liquid residues. The method comprises the following steps of: screening and separating organic matter residues and inorganic matter residues in the kitchen liquid residues; separating grease, water and inorganic salt; performing pulverizing to obtain organic matter particles; adding a fermentation strain to perform fermenting; adding biologicallarvae to perform decomposition; adding water to dilute a decomposition product; and adding acetic acid to adjust the PH so as to obtain an organic fertilizer; The organic matter residues in a degradation disc can be rapidly and effectively treated through the biological larvae, so that the kitchen liquid residue treatment efficiency is improved; the acetic acid is added in the water adding diluting process, and therefore, the nutrient retention rate of the biological organic fertilizer is increased, a soil structure can be improved, the growth of plants is facilitated, the resource utilization degree is improved. The treatment method is simple and convenient. The organic liquid fertilizer prepared from the kitchen liquid residues is simple in process, high in content of phosphorus, potassium, calcium and organic matters, high in fertilizer efficiency and beneficial to rapid growth of plants.

Description

technical field [0001] The invention relates to the technical field of kitchen liquid residue treatment, in particular to a processing method for kitchen liquid residue and an organic liquid fertilizer prepared therefrom. Background technique [0002] With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, the garbage generated in the process of urban production and life has also increased rapidly. Domestic garbage occupies land, pollutes the environment, and affects people's health. The impact of urban living garbage has become more and more obvious. The large increase of urban domestic garbage has made it more and more difficult to dispose of garbage. The resulting environmental pollution and other issues have gradually attracted widespread attention from all walks of life; In order to reduce, reduce and harmless, it is necessary to face mixed collection, low content and calorific val...

AI Technical Summary

Problems solved by technology

[0003] For the treatment of kitchen liquid residues, because it contains a large amount of impurities such as vegetables and oils, the most common treatment at present is simply classified treatment, which cannot effectively turn waste into treasure, and has a negative impact on the surrounding air environment. Pollution is serious, therefore, we have proposed a kind of processing method and the organic liquid fertilizer of kitchen liquid residue
