Embodiment 1

[0034] Produce biochemical humic acid of the present invention as follows:

[0035] 1) Pretreatment and sieving: sieving the kitchen waste to remove inorganic substances;

[0036] 2) Cultivation: the BGB high-temperature complex bacteria are expanded and cultivated according to conventional culture methods to obtain their cultures;

[0037] 3) Blending and fermentation: the BGB high-temperature composite bacterial culture is mixed with kitchen waste and agricultural organic waste (regulator) according to the stated ratio, and fermented to obtain the finished biochemical humic acid; wherein:

[0038] Kitchen waste: 120kg;

[0039] Peanut shell (adjusting material): 80kg;

[0040] BGB compound bacteria fermentation agent (1.5×10 8 cfu / g): 30g;

[0041] Fermentation time: 8 hours;

[0042] Fermentation temperature: 80°C.

Embodiment 2

[0044] Production method is with embodiment 1, and raw material ratio is as follows:

[0045] Kitchen waste: 120kg;

[0046] Adjusting material: wheat straw 40kg, peanut shell 40kg, moisture content adjusted to 55%;

[0047] BGB compound bacteria fermentation agent (2.0×10 8 cfu / g): 30g;

[0048] Fermentation time: 10 hours;

[0049] Fermentation temperature: 60°C.

Embodiment 3

[0051] Production method is with embodiment 1, and raw material ratio is as follows:

[0052] Kitchen waste: 120kg;

[0053] Adjusting material: rice husk 40kg, peanut husk 40kg, moisture content adjusted to 60%;

[0054] BGB compound bacteria fermentation agent (2.0×10 8 cfu / g): 30g;

[0055] Fermentation time: 8 hours;

[0056] Fermentation temperature: 80°C.

[0057] The technical index detection of the BHA that above-mentioned embodiment obtains is shown in the following table:

[0058] Table 2

[0059]

[0060] (The testing standard for total humic acid and free humic acid is GB / P11957-2001, and the testing standard for water-soluble humic acid is HG / P3278-87.)

[0061] It can be seen from the above examples that the conversion rate of organic matter after the kitchen waste is treated by the technical scheme of the present invention is high, which can reach more than 90%. At the same time, the prepared biochemical humic acid is rich in nutrients, not only contai...

Abstract

The invention discloses a novel method for recycling kitchen waste, in particular to a method for preparing biochemical humic acid by using the kitchen waste and the prepared biochemical humic acid product thereby. The kitchen waste treated by using the technical scheme of the invention has high organic conversion ratio of up to over 90 percent. Meanwhile, the prepared biochemical humic acid is rich in nutrition, and contents of the total humic acid, free humic acid and water-solubility humic acid respectively reach 38-42 percent, 35-40 percent and 14-16 percent, therefore, the kitchen waste does not only have a large amount of elements, such as nitrogen, phosphorus, potassium and the like, but also contains a plurality of microelements, such as zinc, ferrum, manganese and the like, and active substances. The method is particularly suitable for fertilizers in agricultural production.

Description

technical field [0001] The invention relates to a method for recycling kitchen waste, in particular to a method for preparing biochemical humic acid from kitchen waste and the biochemical humic acid product prepared therefrom. Background technique [0002] Natural humic acid is mainly formed by long-term complex biochemical processes of animal and plant debris, mainly exists in soil and low-grade coal (peat, weathered coal and lignite), and belongs to non-renewable natural resources, and its alkali extract is called coal Humic acid or mineral humic acid is currently the main humic acid product for industrialization and industrial and agricultural applications. Biochemical humic acid (BHA) is a product rich in humic acid produced through a special biochemical process using organic waste as raw material. Usable organic wastes such as industrial, agricultural and domestic wastes mainly include crop stalks, food processing wastes, poultry manure, sugar industry waste residues, ...
