Example Embodiment
[0024] Example 1
[0025] A method for preparing organic fertilizer from seaweed industrial waste residue, including the following steps:
[0026] (1), pre-fermentation treatment
[0027] In terms of weight ratio, 50% of the dry sample of seaweed waste residue, 49% of the activated sludge of the domestic sewage plant, mixed with 1‰ of the dry weight of the seaweed waste residue, potassium dihydrogen phosphate, 0.5‰ of the corrosion promoter, can it be added here? , 10‰ shell powder, the moisture content is adjusted to account for 50%-70% of the dry weight of the seaweed waste residue, and it is mixed with a tumbling machine;
[0028] (2) Microaerobic fermentation
[0029] The temperature of the pile is raised to 40℃, inoculated with a corrosion promoter, and the pile is turned over every two days, and the water content is measured every 3 days to ensure that the water content of the pile is 50% during the high temperature period, and the fermentation time is 18 days;
[0030] The effe...
Example Embodiment
[0033] Example 2
[0034] (1), pre-fermentation treatment
[0035] According to the weight ratio, 90% of the dried seaweed residue, 9% of wheat bran, mixed with potassium dihydrogen phosphate which accounts for 10‰ of the dry weight of the seaweed waste residue, 1‰ of the shell powder, the water content is adjusted to account for 60% of the dry weight of the seaweed waste residue. Tumbler to mix;
[0036] (2) Microaerobic fermentation
[0037] The temperature of the pile is raised to 45°C, the corrosion promoter is inoculated, and the pile is turned over every three days. The water content is measured every 3 days to ensure that the water content of the pile is 50% during the high temperature period. Fermentation time is 26 days;
[0038] The effective ingredient of the above-mentioned corrosion promoter is a mixture of bacteria and yeast, and the inoculation amount is 7‰;
[0039] (3) Drying and crushing
[0040] After the fermentation is completed, the pile temperature is reduced t...
Example Embodiment
[0041] Example 3
[0042] Combine 40% of the organic fertilizer of seaweed waste residue obtained in Example 2 with 15% of potassium sulfate, 20% of ammonium sulfate, 5% of potassium chloride, and 20% of monoammonium phosphate according to weight percentage to make an organic- Inorganic fertilizer, used in the cultivation and production of green food.
