Abstract

The invention relates to an absorbent of harmful gas generated during material fermentation in the organic fertilizer production process, and the absorbent is a composite aqueous solution formed by sulfates of trace element copper, iron, manganese and zinc, and inorganic acid or organic acidity. The solution can absorb a lot of harmful gas ammonia, hydrogen sulfide, sulfur dioxide and organic harmful gas released in the material fermentation process, and after the harmful gas absorbing solution is detected to be qualified, the solution can be directly used for producing liquid type macro and medium trace element water-soluble fertilizer, and raw materials of water-soluble fertilizer after drying, thereby effectively using macroelement N and medium element S, and avoiding losses of macroelement and medium element in the traditional deodorizing technology and environment pollution.

Description

technical field [0001] The invention relates to an absorbent for harmful gases produced by material fermentation during the production of organic fertilizers in the agricultural field. The absorbent is a composite aqueous solution formed of sulfates of trace elements copper, iron, manganese, and zinc and inorganic acids or organic acids. It is used for absorbing Harmful gases such as ammonia, hydrogen sulfide, sulfur dioxide and organic gases produced during the fermentation of materials are converted into liquid-type water-soluble fertilizers with a large amount of medium and trace elements for agricultural production or used as raw materials for fertilizer production after drying. Background technique [0002] During the production process of organic fertilizer, the fermentation of materials will produce a large amount of harmful gases such as ammonia, hydrogen sulfide and sulfur dioxide. Deodorization, water washing, alkali absorption and simple acid absorption cannot eff...
