specific Embodiment 1
[0026] (1) Preparation of seaweed powder active carrier
[0027] Select 10kg of seaweed residue after extracting seaweed gum, carrageenan, and agar gum as raw material, and put it into a calcification tank for calcification. Add hydrochloric acid with a concentration of 1% by weight to make its pH value reach 5, then add 6% calcium chloride solution by weight to make it flocculate completely, and remove the excess calcium chloride and hydrochloric acid solution in the calcified flocs with clear water Rinse well; dehydrate the calcified floc to obtain a dehydrated solid with a water content of 65%; crush the dehydrated solid into a seaweed powder active carrier with a particle size within the range of 4 mesh to 10 mesh for future use.
[0028] (2) Preparation of seaweed mixture
[0029] Wash 5kg of fresh kelp with fresh water, pulverize it with a pulverizer, freeze it at a low temperature for 6 hours, add 15kg of ethanol solution with a concentration of 70% by weight, mix it a...
specific Embodiment 2
[0032] (1) Preparation of seaweed powder active carrier
[0033] Select 10kg of seaweed residue after extracting seaweed gum, carrageenan, and agar gum as raw material, and put it into a calcification tank for calcification. Add hydrochloric acid with a concentration of 1.5% by weight to make its pH value reach 5, then add 10% calcium chloride solution by weight to make it flocculate completely, and use clear water to dissolve the excess calcium chloride and hydrochloric acid solution in the calcified flocs Rinse well; dehydrate the calcified flocs to obtain dehydrated solids with a water content of 75%; crush the dehydrated solids into seaweed powder active carriers with particle sizes ranging from 4 mesh to 20 mesh for future use.
[0034] (2) Preparation of seaweed mixture
[0035] Wash 5kg of fresh kelp with fresh water, pulverize it with a pulverizer, freeze it at a low temperature for 4 hours, add 15kg of ethanol solution with a concentration of 80% by weight, mix it an...
specific Embodiment 3
[0038] (1) Preparation of seaweed powder active carrier
[0039] Select 10kg of seaweed residue after extracting seaweed gum, carrageenan, and agar gum as raw material, and put it into a calcification tank for calcification. Add hydrochloric acid with a concentration of 2% by weight to make its pH value reach 5.5, then add 8% calcium chloride solution by weight to make it flocculate completely, and remove the excess calcium chloride and hydrochloric acid solution in the calcified flocs with clear water Rinse well; dehydrate the calcified flocs to obtain dehydrated solids with a water content of 60%; crush the dehydrated solids into seaweed powder active carriers with particle sizes ranging from 15 mesh to 20 mesh for future use.
[0040] (2) Preparation of seaweed mixture
[0041] Wash 5kg of fresh kelp with fresh water, pulverize it with a pulverizer, freeze it at a low temperature for 8 hours, add 15kg of ethanol solution with a concentration of 75% by weight, mix it and le...
