Problems solved by technology

The process yield is high, and the physical properties of the product are relatively ideal, but the equipment investment is large, the energy consumption is high, and the organic matter is low (generally about 20%). When used, it is easy to produce acid gas discharge and cause secondary pollution to the atmosphere
In addition, since the raw material is a slurry liquid, in order to meet the requirements of spray granulation, the solid content is generally limited to 35%-40%, and the formula is not easy to adjust, resulting in a single product, which cannot meet the product diversification required by agricultural production. requirements
[0006] 2. Liquid fertilizer: Add various nutrient elements needed for plant growth to the concentrated monosodium glutamate waste liquid, and produce liquid fertilizer after heating and dissolving. This method has simple production process and low equipment investment, but due to the solubility of inorganic nutrients Restrictions, the total nutrient content of the produced fertilizer is low, the packaging cost is high, the transportation radius is small, and the market consumption is small, it is only suitable for use as auxiliary fertilizer, and cannot consume a large amount of MSG waste liquid
[0007] CN1442396 discloses a "amino acid organic and inorganic fertilizer produced by monosodium glutamate by-products and its production method", and CN1136029 discloses a "method for treating monosodium glutamate waste liquid". The technical solutions in these published documents all have high production costs and cannot be applied in large quantities. issues of industrial production

Abstract

An organic fertilizer without environmental pollution is prepared from the sewage generated by preparing gourmet powder, acid lignin, weathered coal, monoammonium phosphate, potassium chloride and trace elements through solidifying reaction and extruding out to obtain granular fertilizer. It has rich nutrients and high water solubility. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to a pollution-free organic fertilizer produced by using monosodium glutamate waste liquid and a preparation method thereof, belonging to the field of organic fertilizers. Background technique [0002] my country is a big producer of monosodium glutamate, with annual output ranking first in the world, accounting for 1 / 2 of the world's output, about 1 million tons. For every ton of monosodium glutamate produced, 20-25 tons of high-concentration organic waste must be discharged. Industrial monosodium glutamate waste liquid contains 3.24% solid matter, 3.12% organic matter, 40-80 / high concentration (chemical oxygen consumption) substance and 20-30 / high concentration (biological oxygen consumption) substance, and about 0.5% reduction Sugar and about 1% glutamic acid bacteria and other substances. Because the waste liquid has the characteristics of high COD, BOD, ammonia nitrogen, organic matter, and large amount of waste liquid, the ...
