Embodiment 1

[0007] A method for manufacturing organic compound fertilizer, infiltrating waste materials such as waste bones, waste fur, and waste viscera in kitchen waste into caustic alkali with a concentration of 5%, and keeping it for a certain period of time (for example, 80 minutes) under pressure and heating conditions, Thereby, a hydrolyzed solution containing soluble substances such as peptone peptides is obtained; the above-mentioned hydrolyzed solution (30%) and superphosphate (70%) are mixed and stirred to cause a chemical reaction, and the neutral matter obtained after the above-mentioned reaction is put into a granulator Granulating in the middle, and finally get granular compound fertilizer.

Abstract

The invention discloses a method for preparing organic compound fertilizer. The method comprises the steps of utilizing caustic alkali and the like for hydrolyzing kitchen garbage, adding calcium superphosphate for a reaction, and conducting pelleting. By means of the method, the kitchen garbage and other traditional waste are effectively utilized comprehensively.

Description

technical field [0001] The invention belongs to the field of fertilizer production, in particular to a method for producing organic compound fertilizer. Background technique [0002] The growth of crops requires a sufficient amount of compound fertilizers containing nitrogen, phosphorus and potassium. Waste bones, waste fur, and waste viscera in kitchen waste are rich in nitrogen, phosphorus, and potassium. However, if the discarded kitchen waste is directly used as base fertilizer, these components are difficult to be absorbed by crops. Contents of the invention [0003] The purpose of the present invention is to provide a method for manufacturing organic compound fertilizer to achieve the purpose of turning waste into wealth. [0004] The technical solution of the present invention is as follows: use caustic alkali to heat and pressurize waste materials such as waste bones, waste fur, and waste viscera in kitchen waste into a solution; mix and stir the above solution w...
