Embodiment 1

[0026] Get alcohol production waste water, at first 300kg waste water is added in the reactor, and the mass concentration that adds 10kg under the condition of stirring is 3wt% perchloric acid. Heating the reaction temperature to 100°C for 14 minutes. The supernatant after separation is the small molecule organic carbon material, which contains organic small molecule compounds such as acetic acid, furfural, and amino acids. Add 0.3 kg of nano-calcium carbonate to the small-molecule organic carbon material, and concentrate the organic carbon solution containing the nano-material by evaporation. On this basis, 0.3 kg of monoammonium phosphate, 0.3 kg of potassium chloride and 0.3 kg of urea are added to obtain an organic carbon macronutrient fertilizer containing nano-calcium.

Embodiment 2

[0031] Get monosodium glutamate production waste water, at first 300kg waste water is added in the reactor, add the 5wt% sulfuric acid of 10kg under the condition of stirring. Heating the reaction temperature to 140°C for 3 minutes. The supernatant after separation is the small molecule organic carbon material, which contains organic small molecule compounds such as acetic acid, furfural, and amino acids. Add 20 kg of nano-calcium carbonate to the small-molecule organic carbon material, and concentrate the organic carbon solution containing the nano-material by evaporation. On this basis, 20 kg of monoammonium phosphate, 25 kg of potassium chloride and 25 kg of urea are added to obtain an organic carbon macronutrient fertilizer containing nano-calcium.

Embodiment 3

[0036] Get MSG yeast production waste water, at first 300kg waste water is added in the reactor, under the condition of stirring, add 15kg of 4% nitric acid and 1L hydrogen peroxide. Heating the reaction temperature to 60°C for 40 minutes. The supernatant after separation is the small molecule organic carbon material, which contains organic small molecule compounds such as acetic acid, furfural, and amino acids. Add 10 kg of nano-calcium carbonate to the small molecule organic carbon material, and concentrate the organic carbon solution containing the nano-material by evaporation. On this basis, 10 kg of monoammonium phosphate, 8 kg of potassium chloride and 8 kg of urea are added to obtain an organic carbon macronutrient fertilizer containing nano-calcium. The fertilizer prepared in Example 3 was applied to pakchoi in Meizhou, Guangdong, and sprayed with water. The application effect showed that the yield was 176.49 kg / mu.

Abstract

The invention discloses organic carbon macro-element fertilizer containing nano synergist and a preparation method of the organic carbon macro-element fertilizer. The preparation method includes the following steps that organic waste water is taken, an acid solution is added for conducting a decomposition reaction, then a small molecular organic compound solution is obtained through a centrifugal separation or settlement method, the nano synergist is added, concentration is conducted, the content of small molecular organic compound is adjusted to be within the range of 5-20%, finally nitrogen element raw materials, phosphorus element materials and potassium element raw materials are added, and the organic carbon macro- element fertilizer containing the nano synergist is obtained. According to the organic carbon macro-element fertilizer containing nano synergist and the preparation method of the organic carbon macro-element fertilizer, the small molecular organic compound is obtained through the organic waste water, meanwhile nanometer materials are introduced, and absorption and utilization of nitrogen, phosphorus and potassium elements by crops are promoted.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic carbon macronutrient fertilizer containing a nano synergist and a preparation method thereof. Background technique [0002] Balanced fertilization is an important technology for high-yield and high-quality crops, and carbon is the number one nutrient element. As the amount of chemical fertilizers continues to increase, the "carbon short board" has become more prominent, causing problems such as low yield, poor quality, and reduced stress resistance of crops. The way crops rely on natural carbon dioxide to supply carbon nutrition can only meet one-fifth of their needs, and crops have been in "carbon starvation" for a long time. [0003] It is reported in the literature that the utilization rate of nitrogen fertilizer in my country is only 20% to 50%, that of phosphorus fertilizer is 15% to 25%, and that of potassium fertilizer is 30% to 35%. The low fertilizer uti...
