Abstract

The invention discloses a preparation method of an amino acid leaf fertilizer. The preparation method of the amino acid leaf fertilizer comprises the following steps of: A, uniformly mixing bean pulp with alcoholic fermentation wastewater, and sterilizing to obtain a fermentation medium; B, inoculating the first seed culture solution containing candida utilis or monilia tropicalis to the fermentation medium for fermentation; C, inoculating the second seed culture solution containing bacillus subtilis and the third seed culture solution containing aspergillus niger to the fermentation culture medium for fermentation; D, inoculating the fourth seed culture solution containing lactobacillus acidophilus to the fermentation medium for fermentation to obtain fermentation liquor; and E, filtering the fermentation liquor and separating solid out of the fermentation liquor, wherein the filter liquor is the amino acid leaf fertilizer. The amino acid content in the amino acid leaf fertilizer is greater than 8%, the content of the water insoluble is less than 5% and the pH value is between 4.0 and 7.5, which completely meet the requirements of National Standard GB / T17419-1998 amino acid containing leaf fertilizer.

Description

technical field [0001] The invention relates to the field of foliar fertilizer production, in particular to a preparation method of amino acid foliar fertilizer. Background technique [0002] Alcohol is an important industrial and food raw material, which is widely used in chemical industry, food and beverage, daily chemical and medical and health industries. It is also a widely used renewable energy source, so it has a very wide range of applications and development prospects. The alcohol fermentation industry is a relatively serious pollution industry. According to the conventional process, about 12-15 tons of wastewater is discharged for every ton of alcohol produced. The treatment of alcohol wastewater has become a bottleneck for the development of various alcohol enterprises. Alcohol wastewater contains a large amount of organic compounds and suspended solids, the main components are sugar, protein, vitamins, etc., and the COD is as high as 30000-60000mg / L, which is a t...
