Problems solved by technology

[0003] When the existing water-soluble fertilizer is produced with yeast thick slurry waste liquid, since the available organic matter in the yeast thick slurry waste liquid has been exhausted, the number of colonies and the activity of yeast in the yeast thick slurry waste liquid are low at this time. Fermentation production of water and fertilizer with yeast thick pulp waste, the efficiency and effect of fermentation are difficult to achieve the expected results, not only prolonging the fermentation cycle, but also the quality of water-soluble fertilizer produced is poor

Abstract

The invention discloses a method for producing humic acid-containing water-soluble fertilizer by means of concentrated yeast cream waste liquor. The method for producing the humic acid-containing water-soluble fertilizer by means of the concentrated yeast cream waste liquor comprises the following specific operation steps of (1) yeast culture; (2) water-soluble fertilizer stoste production; (3) mixed fermentation, wherein equal volumes of yeast culture liquid and water-soluble fertilizer stoste are mixed; (4) concentration and filtration, wherein after fermentation is completed, fermentation liquor is concentrated; (5) inactivation, wherein water-soluble fertilizer filter liquor is placed in a high-pressure steam sterilization tank for sterilization treatment; and (6) filling. According tothe method for producing the humic acid-containing water-soluble fertilizer by means of the concentrated yeast cream waste liquor, the concentrated yeast cream waste liquor is used as a raw material,firstly, the concentrated yeast cream waste liquor is subjected to solid-liquid separation, yeast colonies in the waste liquor are cultured to obtain high-concentration high-activity yeast liquid, thus the fermentation speed of the humic acid-containing water-soluble fertilizer is improved, solid-phase organic matters in the waste liquor are fermented by means of the yeast liquid, thus the wasteliquor is completely recycled, in the whole fermentation process, no waste materials are generated, and meanwhile, the produced humic acid-containing water-soluble fertilizer, in combination with multiple compounds, has a more balanced element content, and benefits growth of crops.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizers, and in particular relates to a method for producing humic acid-containing water-soluble fertilizers by utilizing yeast thick slurry waste liquid. Background technique [0002] Water-soluble fertilizers refer to compound fertilizers containing nitrogen, phosphorus, potassium, calcium, magnesium, trace elements, amino acids, humic acid, alginic acid, etc. that can be completely dissolved in water. Different from traditional granulated fertilizers, water-soluble fertilizers can be sprayed or irrigated. Plants have a higher absorption rate of water and fertilizers and faster absorption, which is beneficial for plants to absorb nutrients and achieve the effect of water and fertilizer integration. [0003] When the existing water-soluble fertilizer is produced with yeast thick slurry waste liquid, since the available organic matter in the yeast thick slurry waste liquid has been exhau...
