Problems solved by technology

If the wastewater is treated by high-temperature concentration and high-temperature granulation, the solid fertilizer will contain a large amount of insoluble matter (macromolecular polymers), which is not conducive to plant absorption and poor fertilizer efficiency.

Abstract

The invention provides liquid organic trace-element fertilizer made from molasses alcohol wastewater. The liquid organic trace-element fertilizer comprises organic carbon liquid and compounds containing medium trace elements, wherein the mass ratio of the organic carbon liquid to the compounds is 100: (2-10). The weight of micromolecular organic matters in the organic carbon liquid accounts for 30-50%, and the complexing rate of the medium trace elements in the organic trace-element fertilizer is 30-60%. The organic carbon liquid is obtained through processing of the molasses alcohol wastewater by acidification reagents and oxidation reagents. A preparation method of the liquid organic trace-element fertilizer has short production cycle, and production energy consumption is reduced; the prepared liquid organic trace-element fertilizer has high water solubility, contains multiple medium trace elements and can be directly or indirectly used for fertilization; the fertilizer effect is good, and yield is increased obviously.

Description

technical field [0001] The invention relates to a liquid organic micro-fertilizer and a preparation method thereof, in particular to a liquid organic micro-fertilizer prepared by using molasses alcohol wastewater and a preparation method thereof. Background technique [0002] In Brazil, the use of molasses alcohol waste liquid to directly irrigate sugarcane has a long history and has received good economic benefits. In France, the most widely accepted treatment methods include anaerobic, aerobic treatment or the use of waste liquids for crop fertilization. At present, the treatment methods of molasses alcohol wastewater in my country include: agricultural irrigation, natural oxidation pond, yeast production by fermentation, biochemical treatment method, concentration treatment method, in addition, adding medium and trace elements and minerals to wastewater and mixing granulation to prepare organic solid fertilizer. [0003] In the prior art, agricultural irrigation and oxid...
