Problems solved by technology

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, and prepared amino acids by hydrolyzing bacterial protein. This method can obtain a hydrolysis rate of about 50%, but high-concentration hydrochloric acid is harmful to The equipment caused serious corrosion, and the equipment was updated quickly, which increased the burden on the enterprise
