Description
Technical field
The invention belongs to technical field of fertilizer production is and in particular to a kind of aminoacid water soluble fertilizer and preparation method thereof.
Background technology
A large amount of waste liquids can be produced, it is highly difficult to process these waste liquids, causes enormous pressure to environmental protection during glutamate production.
Waste liquid still contains many ammonium sulfate in remaining desalinization liquor after extracting ammonium sulfate, also contains substantial amounts of organic, ammonia simultaneously
The nutritional labelings such as base acid, are a kind of extraordinary fertilizer materials.
Many glutamate production enterprises utilize waste liquid to adopt the method for slurry-spraying pelletizing to produce fertilizer, and its production process not only consumes
Mass energy, goes back major polluting atmosphere environment.Because in the production process of Chemical Mixed Fertilizer, temperature must control 500 DEG C～600
DEG C, large quantity of moisture is fallen with flash evapn；Many organic substances in waste liquid can be destroyed and arrange together with flue gas, steam simultaneously
Empty；And, the ph of waste liquid is relatively low, the acid mist producing in process of production can cause air secondary to pollute, and promotes the formation of acid rain.
With the continuous improvement of people's living standard, the prescription also more and more higher to agricultural product for the people, corresponding rush
Enter agrotechnical more new development, the technology such as water-fertilizer integral is increasingly taken seriously and obtains larger development.Therefore, amass
The growth requirement that water soluble fertilizer has adapted to modern agriculture is developed in pole.
Content of the invention
The invention provides a kind of aminoacid water soluble fertilizer and preparation method thereof, it is intended that solve gourmet powder fermenting
