Problems solved by technology

This patent mainly uses the straw of crops or crops to be buried underground to achieve the purpose of sequestering carbon. However, the yield of straw is too low to harvest multiple times in a year, and it can only be harvested in a concentrated and large-scale manner once a year. The landfill is generally far away from the crop planting area, and the transportation cost of transporting straw to the landfill is too high. In addition, adding preservatives will lead to increased costs and environmental pollution
[0004]Although various technologies have been conceived and researched to fix carbon, no ideal carbon fixation method has yet been found
There is no disclosure in the prior art of carbon sequestration through planting (or breeding), harvesting and landfilling of fast-growing herbaceous plants

Embodiment A

[0115] Embodiment A-municipal refuse treatment obtains organic fertilizer

[0116] 1. Sorting out combustibles such as large pieces of wood, cardboard, decorative materials, foam, and construction waste such as cement, bricks, marble, ceramic tiles, and gypsum boards.

[0117] 2. Break open the plastic bag containing domestic garbage to disperse all the items in the bag.

[0118] 3. Use magnetic separation to separate ferrous metals.

[0119] 4. Use the garbage wind sorting system (see CN102601049A) to screen the treated municipal solid waste, screen out the inorganic matter, and crush the remaining organic matter into large particles.

[0120] 5. The crushed organic matter is mixed with human and animal manure, phosphorus fertilizer, nitrogen fertilizer, etc., and the carbon-nitrogen ratio is 20-30:1;

[0121] 6. Dilute the compound beneficial bacteria powder with water by 50 to 100 times, and cultivate it at room temperature for 8 to 12 hours. After obtaining the bacteri...

Embodiment B

[0125] Embodiment B-Urban Domestic Sewage Treatment, Obtain Treated Sewage Rich in Nutrients

[0126] Urban domestic sewage mainly includes kitchen washing water, toilet flushing wastewater and other domestic miscellaneous water. This type of wastewater contains a large amount of suspended solids, chemically or biologically degradable dissolved or colloidally dispersed organic matter, nitrogen-containing compounds (including ammonia nitrogen, nitrate nitrogen, nitrite nitrogen and organic nitrogen), phosphate, potassium sodium and heavy metals Ions, fungal biota, etc. If it is discharged into natural water bodies without treatment or with insufficient treatment, it will lead to eutrophication and accumulation of toxicity in the water body. worsen and pollute the environment.

[0127] 1. Sludge and sewage enter the aeration tank at the same time and are fully mixed. The microorganisms in the aeration tank absorb and decompose the organic matter in the sewage to purify the s...

Embodiment 1

[0132] Example 1 - Valley-type landfill or flat-type landfill

[0133] For a typical landfill see Figure 1 to Figure 3 , the valley type biomass landfill includes a landfill space unit 26, the bottom of the landfill space unit (the bottom of the valley or the bottom of the pit) and the slope 1 are provided with a compacted clay layer 5, the said An anti-seepage liner 6 is provided in the compacted clay layer 5 at the bottom of the pit and the side slope, and a gravel layer 3 is provided on the compacted clay layer 5 at the bottom of the pit, and a soil layer 2 is provided on the gravel layer 3; The landfill space unit 26 fills the valley, the surface layer of the landfill space unit 26 is provided with a B compacted clay layer 33, the B clay layer 33 is provided with a waterproof layer 18, and the waterproof layer 18 is provided with a covering soil layer 17; the edge of the covering soil layer 17 is provided with a lateral drain 19; the landfill space unit 26 is provided ...

Abstract

Disclosed is a method for carbon sequestration by using fast-growing herbaceous plants, fast-growing algae, lichens or mosses, comprising: (1) planting and / or cultivating fast-growing herbaceous plants, fast-growing algae, lichens or mosses in a selected land area or water area; (2) harvesting or recovering the plants, algae, lichens or mosses after growing to a suitable height or size over a period of time; (3) drying the harvested or recovered plants, preferably by natural drying, such as sun drying or air drying, to obtain dried plants, algae, lichens or mosses; (4) transporting the dried plants, algae, lichens or mosses to a landfill and landfilling same; (5) after finishing landfilling, covering the finally landfilled plants with a layer of ordinary soil; and (6) recovering vegetation in the landfill.

Description

technical field [0001] The invention relates to a method for realizing carbon sequestration by planting and / or cultivating, harvesting and burying fast-growing herbaceous plants, and belongs to the field of environmental protection. Background technique [0002] Since the Industrial Revolution in the 18th century, human emissions of CO into the atmosphere 2 As greenhouse gases increase year by year, the atmospheric greenhouse effect will increase accordingly, causing diseases, insects, pests, and infectious diseases on the earth to be on the verge of onset; sea levels will rise; climate abnormalities will increase ocean storms; Serious Problem. In recent decades, due to the rapid increase in population and rapid industrial development, the CO produced by breathing 2 and CO produced by the combustion of coal, oil, and natural gas 2 , greatly exceeding past levels. Atmospheric CO 2 If the increase is doubled, the global average temperature will rise by 1.5-4.5°C, and the ...
