Technical field

The invention relates to the field of environmental protection and agricultural special fertilizer technology, in particular to a water-soluble nano organic carbon fertilizer, a preparation method thereof and an organic compound fertilizer.

Background technique

The discharge of organic waste in China is increasing at an annual rate of 8-10%, and the production of industrial organic wastewater (sugar liquid, yeast liquid, sperm liquid, etc.) is about 2 billion tons. Agricultural organic waste (animal waste) The production of biogas slurry, crop straw, sawdust, vegetable and fruit residues, distiller's cake, mushroom residue, sputum, etc. is about 2.5 billion tons, and urban domestic garbage (food waste, urban sewage) The production of mud, etc. is about 190 million tons, less than 1/3 of the treated organic waste, and the harmless treatment rate is less than 10%. Even if the treated organic waste is treated, the negative impact on the environment is not eliminated. . From a resource science perspective, organic waste is also a resource and is currently the only potential source of growth in the world.

At present, the treatment methods for organic waste include the following: direct agricultural, compost (including bio-humic acid BFA compost), landfill, biogas fermentation and incineration. However, various processing methods have their own drawbacks and weaknesses.

Among them, the direct agricultural use of agricultural organic waste is a tradition in China. Due to the rising labor costs, the amount of farmyard fertilizer is generally heavy, and manpower is transferred to the field to fertilize time and effort. Unless they eat the fruits and vegetables themselves, farmers are not willing to use farmyard manure extensively. This is also an important reason for the large-scale use of chemical fertilizers. The production of farmyard manure has not been properly treated and lacks scientific and technological content, resulting in a large amount of agricultural organic waste resources waste and the generation of harmful gases, pollution of groundwater sources and other new pollution problems. The method of composting (including bio-humic acid BFA composting) covers a large area, labor, time-consuming, low processing efficiency, unstable product quality, low commodity value, and the same amount of farmer's fertilizer, and farmers are not willing to use it in large quantities. Sales are difficult. Pollution problems such as harmful gases are also generated during the production process. Landfill is a common method for urban domestic garbage disposal. It accounts for more than 80% of the amount of garbage disposal in China. It not only fails to use resources reasonably, but also occupies a large amount of land, and is prone to secondary pollution such as leachate and methane gas. The use of organic waste to produce biogas is a good technology, but the initial investment, operational technology and potential hidden dangers, the difficulty of technology promotion and operability are very large, there are secondary treatment problems of biogas slurry and biogas residue. Incineration of organic waste also has technical difficulties and secondary pollution problems, and is not suitable for China's national conditions.

At present, there is a method for the treatment of organic waste, which is used to produce biohumic acid. Biological humic acid plus The engineering process involves microbiology engineering, chemical engineering, biochemistry, physical chemistry and other multilateral disciplines. It is broadly divided into the following technical genres: using straw or wood chips as raw materials, passing solid fermentation, then soaking in lye, acid neutralization, solidification Separation of liquid, production of biological humic acid solution with separated liquid, residue production of solid organic fertilizer; use of fecal residue as raw material, liquid fermentation, solid-liquid separation, production of biological humic acid solution with separated liquid, residue to produce solid organic fertilizer The organic waste water is used as raw material, concentrated, activated, catalyzed, solid-liquid separation, and the biological humic acid solution is produced by using the separated liquid, and the residue is used to produce solid organic fertilizer. The above is the main treatment methods for organic waste in China. In particular, the main technical genres of organic waste treatment in the bio-humic acid industry in China are introduced. They have the following common drawbacks.

The above methods generally appear to occupy a large area, have more labor, consume time and energy, are expensive, and have complicated processes. The production and processing process is prone to secondary pollution, and the conversion of organic waste is not complete, and the utilization rate is low. Industrial production cannot be carried out. In view of this, the present invention has been specifically proposed.
