Embodiment 1

[0027] A method for manufacturing multifunctional composite liquid fertilizer using kitchen waste liquid, adding fast decomposing bacteria to the kitchen waste liquid for degradation treatment, and decomposing macromolecular organic matter into small molecular organic liquid;

[0028] Anaerobic fermentation: adding compound bacteria to the organic liquid for anaerobic fermentation; while producing a part of biogas, an organic liquid rich in nitrogen, phosphorus, lactic acid bacteria and other substances is obtained.

[0029] Aerobic fermentation: Add EM compound functional bacteria to the organic liquid obtained after anaerobic fermentation to carry out aerobic fermentation, that is, multifunctional compound liquid fertilizer.

[0030] Preferably, the degradation treatment is carried out in the pretreatment tank, and the rapidly decomposing bacteria first enter the strain expansion tank for expansion and then enter the pretreatment tank.

[0031] Preferably, the anaerobic fermentation ...

Abstract

The invention discloses a method for preparing a multifunctional compounded liquid fertilizer by using kitchen waste garbage waste liquid. The method comprises the steps: adding fast-decomposing bacteria into the kitchen waste garbage waste liquid for degrading treatment so as to obtain organic liquid; carrying out anaerobic fermentation: adding a compounding bacterium agent into the organic liquid for anaerobic fermentation; and carrying out aerobic fermentation: adding EM compounding functional bacterium agent into the organic liquid, obtained after anaerobic fermentation, for aerobic fermentation, thereby obtaining the multifunctional compounded liquid fertilizer. According to the method, degrading treatment is carried out by adopting the fast-decomposing bacteria, so that the hydrolytic acidification speed is high, the time required for degradation is short, and the efficiency is increased.

Description

Technical field [0001] The invention relates to a method for processing kitchen waste liquid, in particular to a method for manufacturing multifunctional compound liquid fertilizer by using kitchen waste liquid. Background technique [0002] Food waste refers to the food residues and processing waste generated in the lives of residents and the fruit and vegetable wholesale market in the vegetable market. [0003] The amount of food waste in my country is huge, and it is rising rapidly. In general, kitchen waste accounts for more than 50% of the household waste generated in large cities every day. Kitchen waste has the characteristics of high moisture content, high organic matter content, perishable, rich nutrition, etc. During the storage, collection, transfer and disposal of kitchen waste, due to its high moisture content and organic matter content, it is easily It rots and smells and breeds mosquitoes and flies within a period of time, which pollute the urban environment. How t...
