Example Embodiment

[0093] On the other hand, the embodiment of the present application provides a preparation method of an organic fertilizer rich in black humic acid, which is characterized in that, comprising the following steps:

[0094] The waste substrate is treated by the decomposing method described in the above embodiment;

[0095] The prepared humic acid-rich organic fertilizer substrate is adjusted by using KOH to adjust the pH value of the humic acid-rich organic fertilizer substrate to 11 to 12, and the clear liquid and the humic acid-rich organic fertilizer substrate are filtered and separated. solid matter;

[0096] Using wood vinegar liquid-inorganic acid mixed solution to adjust the pH value of clear liquid to 3 to 5, to obtain two rounds of clear liquid and sediment, and concentrating the moisture content of sediment to less than 25% to obtain an organic fertilizer rich in black humic acid.

[0097] The wood vinegar-inorganic acid mixed solution can be wood vinegar-hydrochloric...

Abstract

The invention discloses a method for composting lignocellulose waste and preparing organic fertilizer rich in humic acid. The method for composting lignocellulose waste comprises the following steps: carrying out a first lignin degradation period and a second cellulose hemicellulose degradation period, and fermenting until a GI index is greater than or equal to 80%, composting waste matrix into an organic fertilizer substrate rich in humic acid, wherein according to the composting method, in the lignocellulose waste degradation process, the humic degree is high, the composting time is short, and the product is rich in humic acid.

Description

technical field [0001] The application belongs to the technical field of agricultural waste processing, and in particular relates to a method for decomposing lignocellulosic waste and preparing organic fertilizer rich in humic acid. Background technique [0002] Lignocellulose is the species with the largest annual biomass production on Earth. Some of these species are closely related to human production and life, such as crop stalks, grain husks, and solid-state fermentation waste. Rice is the basic food that more than half of the world's population depends on for survival, and it is also the basic food for most Chinese people. my country's annual rice processing produces 40 million tons of rice husks, more than 14 million tons of rice bran and other valuable by-products that have not been well developed and utilized. They are usually discarded directly or burned in the open, causing serious environmental pollution, and more importantly, a large number of resources are was...
