Problems solved by technology

In recent years, the domestic water-soluble fertilizer industry has developed rapidly, but in terms of fertilizer performance and production technology, it is far behind similar foreign products. The current situation restricts the further development of the domestic water-soluble fertilizer industry. The development of new fertilizers with high efficiency and multiple effects is imminent and will become a new direction for future development.
[0003] Amino acid fermentation tail liquid is the liquid extracted from the amino acid industrial production process. It contains a large amount of bacterial protein and ammonia nitrogen substances. It is difficult to process and costly, and it is difficult to obtain cost-effective by-products.
The applicant's previous patented technology "2014105587445, a method for producing liquid fertilizer by using glutamic acid wastewater" discloses a method for preparing liquid fertilizer by using amino acid fermentation wastewater. , using high-concentration hydrochloric acid of 6-8mol / L, stirred and hydrolyzed at 60°C for 12-16 hours to hydrolyze bacterial protein. This method can obtain a hydrolysis rate of about 50%, but high-concentration hydrochloric acid will cause serious damage to the equipment. Corrosion, rapid equipment update, aggravating the burden on enterprises

Abstract

Belonging to the field of amino acid fermentation tail liquor treatment, the invention discloses a liquid fertilizer made from amino acid fermentation tail liquor. The liquid fertilizer is prepared according to the process of: 1) separation, drying and crushing, 2) strain cultivation, 3) fermentation treatment, 4) preparation of a urea-humic acid complex, and 5) preparation of the fertilizer. Amino acid fermentation tail liquor contains a large amount of mycoprotein. According to the invention, the fertilizer preparation utilizes mycoprotein and waste liquor at the same time, eliminates the waste liquor treatment process, lowers the production cost, and realizes turning of waste into treasure.

Description

technical field [0001] The invention belongs to the field of amino acid fermentation tail liquid treatment, and in particular relates to a liquid fertilizer prepared by using amino acid fermentation tail liquid. Background technique [0002] Liquid fertilizer has significant advantages such as good water solubility, high absorption rate, and quick effect.
