The invention relates to the technical field of water-soluble fertilizers, in particular to a macroelement water-soluble fertilizer based on livestock and poultry breeding wastewater and a preparation method thereof, and the macroelement water-soluble fertilizer comprises the following raw materials in parts by weight: 50-60 parts of a breeding waste liquid concentrated base solution, 17-20 parts of amido nitrogen, 20-25 parts of potassium polymetaphosphate, 17-20 parts of phosphorus element, 17-20 parts of potassium oxide, 0.5-1 part of trace element boron, 0.5-1 part of trace element copper and 60-65 parts of solvent water. According to the macroelement water-soluble fertilizer disclosed by the invention, a base solution obtained by concentrating culture waste liquid is used as a matrix, the raw materials are coordinated, and the filling agent doped with the modified carbon nanotubes and the modified functional agent are added as blenders, so that the macroelement water-soluble fertilizer is prepared through the synergistic effect of the filling agent and the modified functional agent; the obtained water-soluble fertilizer product has obvious improvement effects on cotton crop disease resistance, seed cotton yield and fiber quality.

This invention relates to the field of mineral-based solid waste resource recycling, specifically to a solid waste-based homogeneous slurry and its preparation method. Using mineral-based solid waste as the core raw material, supplemented with water, grinding aids, and potential regulators, a stable solid waste-based homogeneous slurry is prepared through a complete process including raw material pretreatment, coarse grinding, fine grinding, graded closed-loop screening, precise Zeta potential control, and ultrasonic homogenization. This slurry can be used with composite solidifying agents to prepare solidified soil for engineering applications. This invention establishes a precise matching mechanism between the calcium content of solid waste and the potential regulator. Potassium hexapolymetaphosphate is preferred for high-calcium mineral-based solid waste, while sodium pyrophosphate is preferred for low-calcium mineral-based solid waste. It is suitable for all types of high-calcium and low-calcium bulk mineral-based solid waste. The prepared slurry exhibits excellent homogeneity and can be stored for a long time. The solidified products have high mechanical strength and low performance dispersion. The preparation process parameters are controllable and suitable for large-scale continuous production, showing broad application prospects.
