Embodiment 1

[0007] A method for processing compound fertilizers, infiltrating waste materials such as waste bones, waste fur, and waste viscera in kitchen waste into caustic potash with a concentration of 5%, and keeping it under pressure and heating for a certain period of time (for example, 60 minutes) , so as to obtain a hydrolysis solution containing soluble substances such as peptone peptide; the above hydrolysis solution (30%) and superphosphate (70%) are mixed and stirred to cause a chemical reaction, and the neutral substance obtained after the above reaction is put into granulation Granulate in the machine, and finally get granular compound fertilizer.

Abstract

The invention discloses a processing method of compound fertilizer. The processing method comprises the following steps: hydrolyzing kitchen garbage by using potassium hydroxide; adding calcium superphosphate for reacting and granulating. The invention provides a path for effectively and comprehensively utilizing traditional wastes such as the kitchen garbage.

Description

technical field [0001] The invention belongs to the field of organic fertilizer manufacturing, and in particular relates to a processing method of 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 ingredients are difficult to be absorbed by crops. Contents of the invention [0003] The purpose of the present invention is to provide a processing method of compound fertilizer, so as to achieve the purpose of turning waste into wealth. [0004] The technical solution of the present invention is as follows: use caustic potash 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 abo...
