Embodiment 1

[0023] Remove the silt from the sargassum raw material, dry or sun-dry at 55°C, and crush; accurately weigh 100kg of the dried and crushed sargassum raw material, add fresh drinking water with a raw material weight of 600kg to the above-mentioned sargassum powder, and put it in a water bath at 55°C Soak for 2 hours; adjust the pH value of the liquid to 4 with HCl, add 0.4% cellulase consisting of 40% endo-β-glucanase, 30% exo-β-glucanase, and 30% β-glucosativa , enzymatic hydrolysis for 8 hours; add 0.3% protease consisting of 45% neutral protease and 55% papain, 0.3% pectinase consisting of 55% pectin lyase and 45% pectin esterase, and continue enzymatic hydrolysis for 3 hours. Stir, centrifuge after enzymatic hydrolysis; add 2% Na 10 times the weight of Sargassum to the above centrifuged Sargassum 2 CO 3 Digest the solution in a water bath at 50°C for 2 hours; then add 5 times the volume of fresh drinking water at 50-60°C to dilute for 1 hour, after fully diluting evenly, f...

Embodiment 2

[0026] Remove the sediment from the raw material of Sargassum, dry or sun-dry it at 65°C, and crush it; accurately weigh 100kg of dried and crushed raw material of Sargassum, add fresh drinking water with a raw material weight of 700kg to the above-mentioned Sargassum powder, and put it in a water bath at 60°C Soak for 3 hours; adjust the pH value of the liquid to 6 with HCl, add 0.5% cellulase consisting of 40% endo-β-glucanase, 30% exo-β-glucanase, and 30% β-glucosativa , enzymatic hydrolysis for 10 hours; add 0.6% protease consisting of 45% neutral protease and 55% papain, 0.4% pectinase consisting of 55% pectin lyase and 45% pectin esterase, and continue enzymatic hydrolysis for 4 hours, Stir, centrifuge after enzymatic hydrolysis; add 4% Na 12 times the weight of Sargassum to the above centrifuged Sargassum 2 CO 3 Digest the solution in a water bath at 60°C for 3 hours; then add 6 times the volume of fresh drinking water at 50-60°C to dilute for 2 hours, after fully dilu...

Abstract

The invention discloses a method for preparing sodium alginate and organic fertilizer from Sargassum algae, which is characterized in that the method comprises the following steps: (1) raw material pretreatment (2) fiber enzymatic hydrolysis (3) protein enzymatic hydrolysis ( 4) Salt water digestion (5) dilution filtration (6) decolorization (7) CaCl2 solution treatment (8) ion exchange (9) preparation of sodium alginate (10) preparation of Sargassum organic fertilizer. The invention uses protease, pectinase and cellulase to make compound enzyme according to the scientific ratio, and pretreats the raw materials, which is beneficial to improve the extraction rate of sodium alginate; fully develops and utilizes the humic acid resources in my country, and produces Water is the solvent, organic fertilizer rich in humic acid and macronutrients. The high-value comprehensive utilization of wakame spore leaves has been realized.

Description

technical field [0001] The invention relates to the field of utilization of sargassum, in particular to a method for preparing sodium alginate and organic fertilizer from sargassum. Background technique [0002] At present, the world is facing the huge pressure of energy shortage and environmental pollution, and the development of clean and renewable energy has become an important means to solve the crisis of petrochemical resources and energy. Bioethanol has been widely concerned as a clean fuel and gasoline additive. At present, the preparation of fuel ethanol in my country mainly focuses on terrestrial raw materials such as straw, bagasse, wood chips and cassava, but there are few studies on the preparation of bioethanol from marine biological resources, and the technical research on the development of sargassum biomass energy is relatively backward. [0003] Using Sargassum processing waste rich in cellulose, Sargassum polysaccharides and mannitol to prepare fuel ethano...
