Some simple treatment methods for privately collected organic waste not only fail to effectively utilize organic waste, but even cause these organic waste to harm the society due to improper disposal. The most common way is to directly feed pigs with kitchen waste, and this garbage pig is Consumers eat it, seriously infringing on the i...

Abstract

The invention provides a green organic fertilizer produced from food waste and a preparation method thereof, and relates to the field of agriculture, in particular to a solid organic fertilizer and aliquid organic fertilizer produced from food waste and a preparation method thereof. The green organic fertilizer comprises the following raw materials in parts by weight: 85-90 parts of food waste, 5-10 parts of urea and 1-5 parts of modified rhodotorula glutinis. Innocent treatment of the food waste is conducted, specifically, fermentation treatment is conducted through special microorganisms, and the urban food waste is fermented and decomposed at high speed and finally becomes a green organic fertilizer.

Example Embodiment

[0026] Embodiment 1: a kind of catering waste produces green organic fertilizer and preparation method thereof, and its raw material is by weight:

[0027] 88 parts of solid food waste, 8 parts of urea, and 4 parts of modified Rhododendron, to obtain solid organic fertilizer;

[0028] 90 parts of catering liquid waste, 3 parts of urea, 2 parts of polyaluminum chloride, and 5 parts of modified Rhodotorula vera to obtain liquid organic fertilizer;

[0029] The preparation of the above-mentioned catering waste to produce green organic fertilizer includes the following steps:

[0030] a. Pulverize the recycled catering waste with a pulverizer;

[0031] b. Use a solid-liquid separator to separate solids such as rice, vegetables, and bones;

[0032] c. Use a high-speed centrifuge to separate the remaining liquid from oil and use it as other industrial oils;

[0033] d. Add food waste solids into a stirring tank with a heating device, and in a sealed state, use an ultraviolet sterilizer for sterilization, and then heat it up to 85-90 degrees for further high-temperature sterilization;

[0034] e. put into another fermenter after cooling, add urea and modified red yeast, and ferment naturally for 24 hours in a sealed state to obtain solid organic fertilizer;

[0035] f. Add the catering liquid waste into the stirring tank with the heating device, in a sealed state, sterilize it with an ultraviolet sterilizer, and then heat it up to 85-90 degrees for further sterilization with high temperature;

[0036] g. After cooling, put it into another fermenter, add 3 parts of urea, 2 parts of polyaluminum chloride and 5 parts of modified red yeast, in a sealed state, ferment naturally for 24 hours, extract about 97% of the liquid organic fertilizer, and the bottom remains About 3% is the mixed crystal of sodium chloride (salt) and polyaluminum chloride - aluminum hydroxide, which can be purified and turned into other industrial products;
