Special biological fish-fertilizer for aquaculture and preparation method thereof

The invention discloses a special biological fish fertilizer and a preparation method for the fertilizer used in aquiculture; wherein, the biological fish fertilizer mainly comprises raw materials as follows: microbiological preparation, inorganic fertilizers, fermentation organics, micro-mineral amino acid chelate, mineral composites, and water quality improver. The preparation method for the special biological fish fertilizer in aquiculture comprises steps as follows: microbiological preparation is produced; fermentation organics is then produced, and the micro-mineral amino acid chelate is produced, eventually the finished products are made. The special biological fish fertilizer has the advantages of limiting the growth and reproduction of the harmful algae, promoting the large-scale growth and reproduction of the suitable food for fish, effectively improving the water quality and purifying the water environment, strengthening the fish immunity, reducing the diseases, reducing cost due to the small use level, convenient use, mild odor, no pollution to the water, and environment protection. By combining the modern bioengineering technique, low-temperature drying technique, spray-drying technique, and super-fine crushing techniques, the preparation method has the advantages of stable quality for the fish fertilizers and lower overall cost.

Improved soil matrix and remediation method for green mine

The invention provides an improved soil matrix and a remediation method for a green mine. According to the improved soil matrix and the remediation method for the green mine, a certain gradient of a mountain is formed by trimming a cliff of the mine, a hard material is laid in a certain mode, then a plastic-coated metal net covers the hard material, and finally, the novel improved soil matrix covers the plastic-coated metal net with a certain thickness so as to realize the effective remediation of the mine. The improved soil matrix and the remediation method for the green mine have the beneficial effects that the improved soil matrix can stably float on the surface of the mine with the gradient of less than 80 degrees, the adhesive force is greater than 20 Kpa, the inner friction angle isgreater than 18 degrees, the anti-corrosion index is greater than 99.1%, the anti-scouring index is greater than 2.0 L.min/g, the structure is high, and scouring of heavy rainfall or heavier can be effectively resisted after three days of spraying; the improved soil matrix is rich in nutrition, loose and breathable, and is suitable for growth of plants; and lots of organic matter such as agricultural and forestry leftovers are adopted, so that the water storage performance is high, and the construction cost and the maintenance cost are greatly saved.

Combined anaerobic fermentation process for organic solid wastes

The invention discloses a combined anaerobic fermentation method of organic solid wastes. The organic solid wastes used for the combined anaerobic fermentation include domestic wastes, excess sludge, feces, kitchen waste, straws, etc. The method comprises the following steps: carrying out different pre-processing processes to obtain organic materials with a granularity less than 5 mm; passing through a cutting pump, adjusting the C/N ratio, adjusting the water content, etc. to obtain a homogeneous fermentation substrate with a solid holdup of 2 to 10%; hydrolyzing and acidifying the fermentation substrate in the presence of a hydrolase; fermenting for a period of 15 to 25 days under the condition of stirring at a middle temperature of 32-38 DEG C to obtain biogas, which can be used for energy supply or output of a system; aging and desalting the biogas liquid to obtain a liquid humic acid fertilizer; and processing the biogas residues to a granular humic acid fertilizer. The fermentation substrate has proper C/N ratio to obviate feedback suppression of the substrate during the fermentation of a single material and simultaneously can enhance the hydrolysis effects of celluloses, lignin, hemicelluloses, etc. The method has the advantages of easy flow pattern control, low energy consumption, and no generation of sewages, and can obtain the high-quality biogas fluid and the high-quality granular humic acid fertilizer.
