Embodiment 1

[0029] Example 1: The dehydrated seaweed slag has a moisture content of 80%, which is controlled at 60% by natural drying, mixed with 3‰ potassium dihydrogen phosphate and 2‰ biological fermentation agent, and mixed with a turner. When the pile temperature rises to 60°C, use a forklift or a turning machine to turn the pile to increase air permeability and lose moisture. Record the temperature every day and turn it over. The aerobic fermentation time is 15 days. After the aerobic fermentation, a large amount of white hyphae will be produced in the heap, and the materials will be piled up to facilitate the formation of humus. The anaerobic fermentation time is 15 days. The decomposed material is sieved with a 1-purpose sieve, and the material that does not pass the sieve is pulverized with a pulverizer, dried at 70° C., and the moisture is controlled below 15%, and the powdered seaweed organic fertilizer is made. The sieved and pulverized materials are granulated by an extrusion...

Embodiment 2

[0030] Example 2: The moisture content of dehydrated seaweed residue is 80%, and the moisture content is controlled at 62% by means of drying, mixed with 5‰ potassium dihydrogen phosphate and 1.5‰ biological fermentation agent, and mixed with a turning machine. When the pile temperature rises to 58°C, use a forklift or a turning machine to turn the pile to increase air permeability and lose moisture. Record the temperature every day and turn it over. The aerobic fermentation time is 14 days. After the end of the aerobic fermentation, a large amount of white mycelia will be produced in the heap, and the materials will be piled up. The anaerobic fermentation time is 16 days. The decomposed material is sieved with a 1-purpose sieve, and the material that does not pass the sieve is crushed with a pulverizer, dried, and the moisture is controlled below 15%, and the powdered seaweed organic fertilizer is obtained. The sieved and pulverized materials are granulated by an extrusion gr...

Embodiment 3

[0031] Example 3: The moisture content of dehydrated seaweed residue is 80%, and the moisture content is controlled at 65% by squeezing, mixed with 6‰ potassium dihydrogen phosphate and 2.5‰ biological fermentation agent, and mixed with a turning machine. When the pile temperature rises to 65°C, use a forklift or a turning machine to turn the pile to increase air permeability and lose moisture. Record the temperature every day and turn it over. The aerobic fermentation time is 18 days. After the aerobic fermentation, a large amount of white hyphae will be produced in the heap, and the materials will be piled up to facilitate the formation of humus. The anaerobic fermentation time is 20 days. The decomposed material is sieved with a 2-purpose sieve, and the material that does not pass the sieve is crushed with a pulverizer, dried, and the moisture is controlled within 15%, and the powdered seaweed organic fertilizer is obtained. The sieved and crushed materials are granulated b...

Abstract

The invention provides a method for preparing seaweed organic fertilizer, which is produced by fermenting waste residue after seaweed gel is extracted. Aiming at the problem that the seaweed residue is not easy to degrade so as to cause difficult fermentation, the method comprises the step of adding 0.1 to 1.5 percent of potassium dihydrogen phosphate into components to convert insoluble calcium alginate into soluble potassium alginate, accelerate fermentation and decomposition of the seaweed residue, reduce fermentation time by 5 to 8 days, reduce decomposition time by 5 to 10 days, reduce production period remarkably, and improve efficiency.

Description

technical field [0001] The invention relates to a preparation method of seaweed organic fertilizer, in particular to the comprehensive utilization and treatment of waste residue produced by seaweed chemical enterprises after producing seaweed gel, and belongs to the technical field of comprehensive management of agricultural and forestry waste. Background technique [0002] my country has a vast sea area and a long coastline, and is rich in seaweed resources. There are a large number of seaweed processing enterprises. In the process of using seaweed to process and extract seaweed gel, this industry will produce a large amount of waste-seaweed floating residue. In order to prevent environmental pollution, Enterprises generally adopt the method of adding calcium chloride flocculation dehydration to separate from wastewater. The seaweed residue contains about 80% water, and its main components are seaweed fiber, calcium alginate, protein, fucoidan, chitosan, polyphenols , betaine...
