Embodiment 1

[0057] 1. Inoculation and cultivation

[0058] Boil clear river water with a pH value of 8.5 and a salinity of 0.5-1‰ for 5-10 minutes to kill microorganisms, and pour it into a sterilized container. Sodium hypochlorite (NaCIO) with an available chlorine content of 10-15% is preferably used as a container disinfectant. After cooling, add a complexing agent, such as ethylenediaminetetraacetic acid (EDTA) to complex heavy metal ions, and obtain culture water that removes heavy metal ions after disinfection.

[0059] Add 1-5% sodium nitrate (NaNO 3 ), Potassium dihydrogen phosphate (KH 2 PO 4 ), ferric citrate (FeC 6 h 5 o 7 ·5H 2 0), sodium silicate (Na 2 SiO 3 ), vitamin B 1 , Vitamin B 12 . Mix vigorously, non-polluting algae liquid and culture water at a volume ratio of 1:1 to 3, and place in a place with sufficient light. Room temperature 20-25°C, stirring once an hour.

[0060] After cultivating for 3-5 days, add sterilized river water, whose volume is 10-20 ti...

Embodiment 2

[0076] 1. Breeding site preparation

[0077] Use bamboo poles, wooden squares, metal or other composite materials to make floating rafts, pull parallel ropes between the two floating rafts, and tie a float every 5-6m between the ropes. The seedling ropes are tied to the ropes, and the distance between the seedling ropes is more than 1m, and the distance between the kelp seedling ropes can reach 2-3m. A certain weight of masonry is hung from the bottom of the seedling rope to straighten the seedling rope. Also can be provided with a slender rope parallel to the upper slender rope at the bottom of the seedling rope, and tie the bottom of the seedling rope to the lower slack rope.

[0078] Polyethylene rope and palm rope can be used for rope and seedling rope. Palm rope fiber contains a large amount of soluble substance tannin, which has a certain poisonous effect on seaweed seedlings. The treatment method is: before making the brown rope, cook the material at high temperature ...

Abstract

The invention discloses a method for implementing carbon sequestration by means of planting, harvesting and dumping fast-growing algae. The method includes reproducing progenies of unicellular algae by means of fission; reproducing progenies of multi-cellular algae by means of spore reproduction; expanding the cultivation area; implementing high-yield cultivation and scientific dumping by means of production management and repeated harvesting. The method has the advantages that CO<2> in the atmosphere is converted into organic compounds by the aid of photosynthesis of the algae, the organic compounds are dumped under stratums, accordingly, negative growth of global carbon emission is realized, and the atmospheric greenhouse effect is relieved; melting of ice layers of the earth is suppressed, seal-level rise is controlled, and the climate and the biodiversity of the earth are maintained; and the survival time of the mankind on the earth can be prolonged.

Description

technical field [0001] The invention relates to a method for realizing carbon fixation through planting, harvesting and landfilling of fast-growing algae, belonging to the field of environmental protection. Background technique [0002] Atmospheric CO 2 Concentrations continue to rise, and global environmental change has become a key factor affecting sustainable human development. The ocean acts as a carbon sink, continuously absorbing CO from the atmosphere 2 . The rivers and lakes in the world have large areas and long coastlines, and there are many kinds of algae plants with huge output; algae absorb CO in the process of photosynthesis 2 release O 2 . The ocean has absorbed more than a third of the CO emitted by humans since the Industrial Revolution 2 plays an important role in mitigating climate warming. The annual total carbon sequestration of marine phytoplankton is 31×10 9 tons of carbon, and algae bio-absorb carbon much faster than trees, and algae populatio...
