Problems solved by technology

[0002] During the production process of organic fertilizer, material fermentation will produce a large amount of harmful gases such as ammonia, hydrogen sulfide, sulfur dioxide and other harmful gases. The removal process adopts biological deodorization, water washing, alkali absorption and simple acid absorption, which cannot effectively utilize the nutrients required for agriculture

example 1

[0008]

[0009]

[0010] After making up 100% of the water, stir fully to dissolve all the materials, then the harmful gas absorbent will be obtained.

example 2

[0012]

[0013] Make up 100% of the water, and fully stir to dissolve all the materials, which is the harmful gas absorbent.

[0014] The following are the properties and active ingredient content of the new water-soluble fertilizer prepared after the absorbent absorbs harmful gases:

example 3

[0016] Absorbent in example 1 is directly prepared into blue liquid water-soluble fertilizer after absorbing harmful gas, pH value is 6.2 (1% aqueous solution), N content 13.5%, S content 4.9%, Cu content 2.4%, Zn content 0.9%.

Abstract

The present invention relates to preparation of a novel water-soluble fertilizer through absorbing harmful gases produced by material fermentation during organic fertilizer production process with an absorption agent, wherein the absorption agent is a composite aqueous solution formed by a sulfate of a trace element such as copper, iron, manganese and zinc and an inorganic acid or an organic acid, a large amount of harmful gases released during a material fermentation process can be absorbed with the solution, and the solution absorbing the harmful gases is directly used for preparing the novel water-soluble fertilizer, wherein the harmful gases comprise ammonia, hydrogen sulfide, sulfur dioxide and the like. With the process, macro element N and medium element S in the harmful gases are effectively utilized, and macro element and medium element loss and environment pollution caused by the traditional deodorizing process are avoided.

Description

technical field [0001] The invention relates to the preparation of a new type of water-soluble fertilizer by absorbing the harmful gas produced by the fermentation of materials in the organic fertilizer production process in the agricultural field. The composite aqueous solution is used to absorb harmful gas ammonia, other nitrogenous gases, hydrogen sulfide, sulfur dioxide and organic gases produced during the fermentation process of materials, and convert them into liquid-type large, medium and trace element new water-soluble fertilizers for agricultural production. Background technique [0002] During the production process of organic fertilizer, material fermentation will produce a large amount of harmful gases such as ammonia, hydrogen sulfide, sulfur dioxide and other harmful gases. The removal process adopts biological deodorization, water washing, alkali absorption and simple acid absorption, which cannot effectively utilize these nutrients required by agriculture. ...
