Description

Carbon sequestration capacity reinforcing system for aquatic organisms
Technical Field
The invention relates to the field of carbon neutralization, in particular to a carbon sequestration capacity enhancing system for aquatic organisms.
Background
As the Chinese energy is mainly fossil energy, the occupation ratio in 2019 is as high as about 85 percent, and CO is generated in the current year2The emission amount accounts for 28.8% of the international total amount, so the international emission reduction pressure is huge. And with the continuous and rapid development of the country and the improvement of the living standard of people, the energy consumption of everyone will continue to rise in the next few years. At present, emission reduction schemes such as rapid change of industrial structure, replacement of clean energy by a whole industrial chain and the like have certain difficulty, so that increase of carbon sink becomes an important means for solving the problem of carbon neutralization.
The technological routes for increasing carbon sequestration in various countries mainly include the development of biological carbon sequestration and carbon capture-utilization and sequestration (CCUS). But CO2Industrial carbon capture and geological sequestration are costly and risky, and practice has proven that their effectiveness also needs to be weighed. The international popular biological carbon sequestration has obvious defects: the key problem is as follows: the high carbon fixation environment is not equal to the high effective burial environment internationally, and carbon sink is taken as the main content of emission reduction, including forests, ecological regions, soil, wetlands and the like. China also has made obvious achievements in the research and practice of biological carbon sink, except for the land forest in different zones. Mangrove forest and wetland thereof are often regarded as the most important main body of carbon sequestration and have the largest carbon sequestration potential, however, although mangrove forest, marsh wetland and soil have high carbon sequestration potential, the organic carbon storage of wetland at high temperature is not increased, but is inversely proportional to the temperature. It is therefore believed that organic matter is decomposed to CO at high temperatures2And the carbon is returned to the atmosphere again, and the high carbon capture in tropical and subtropical climates does not really become an effective carbon sink, so that the carbon burying efficiency is not high.
Efficient storage of carbon sinks requires exploration of the stability of the buried environment. Coal, oil, especially black shale (source rock) in geological processes are natural continuous sedimentary stable carbon fixation products which are difficult to be in natural environmentDecomposition and oxidation to CO2. Although the carbon sequestration capacity of south China wetland and soil is not low every year, the carbon sequestration capacity of the wetland and the soil cannot be multiplied after being saturated, namely the carbon content of the soil cannot be continuously accumulated, and the carbon sequestration capacity cannot be newly increased after the carbon sequestration-decomposition balance is achieved, which may be a main reason for the carbon sequestration of the soil which is not recognized by the Kyoto protocol. The sedimentary process is an accumulation process, black shale or source rock is a common type of sedimentary rock in basin sedimentary, also a primary form of fossil energy. Only organics that would stabilize the carbon sink into geological deposits (unlike CO)2Geological burial) that effective carbon sequestration and atmospheric carbon removal is complete. Otherwise, even if the carbon sequestration potential is maximized, the carbon produced returns to the atmosphere years later, and this carbon sink is of insufficient significance. Therefore, the continuous deposition process of the organic matters meets the requirement of effective carbon neutralization. While carbon sequestration research requires attention to the synergistic issues of carbon capture and carbon sequestration.
China strives to realize carbon neutralization before 2060 years, and the carbon neutralization pressure is huge in large countries which account for 85% of fossil energy. Internationally prevalent carbon sequestration (biosolidation of carbon and CO)2Sealed) has defects: CO 22The sequestration cost is high and the scale is limited, but the modern biological carbon sequestration technology has obvious contradiction. The contradiction is mainly reflected in that: the high-carbon capture warm conditions (such as mangrove environment and the like) are the environment for high-speed degradation of organic matters, and degradation products CO2It will return to the atmosphere and become an ineffective carbon sink.

The inventor finds out through intensive research that large-scale and high-efficiency carbon burying conditions, such as peat burying mainly distributed in alpine zones, are just low-carbon capture environments. In fact, the 3.5 hundred million years ago carbolite has given our important hint: the stone charcoal age is the largest coal-forming period (stable burial of a large amount of organic carbon worldwide) and the largest ice period of apparent universities in the earth, and the climate is obviously zonal. At this time, the atmospheric carbon dioxide rapidly decreases and the atmospheric oxygen concentration increases.
Meanwhile, the inventor has completed the simulation of the organic matter degradation-mineralization experiment and found that when the temperature of the sediment embedding area is lower than a certain value, the sediment environment can actively adsorb and absorb the organic matters in the water body, and the degradation speed of the organic matters in the sediment is obviously reduced or even stopped, so that the organic matters can be stably embedded and stored for a long time, and the effective carbon sink which can be really stored for a long time is settled and stabilized.
Algae have a carbon sequestration capacity that is higher than that of terrestrial plants, such as microalgae, by 10 times that of terrestrial plants. The carbon fixation simulation method is carried out by an experimental method, at present, carbon capture is mainly focused, for example, the experimental simulation results of China in the aspects of utilizing a photobioreactor and the like are great, the yield of high-density culture of chlorella can reach 10-40 g/day/square meter (dry weight), and the carbon dioxide fixation capacity of microalgae is 10 times of that of land plants. Calcified algae may trap and deposit both organic and inorganic carbon, and although carbon capture rates are generally not high, they are characterized by both organic and inorganic carbon burial.
The coke period is the global ice season with the lowest concentration of carbon dioxide and the lowest temperature of the global atmosphere, and obvious climate zonation and a large amount of coal burial appear simultaneously in the period. The modern peat is distributed in China, so that the eastern parts of the Yunobi plateau and the Qinghai-Tibet plateau are extremely rich, and the northeast and the east China plain are rich. South China, which has warm climate and the largest carbon fixing capacity, is quite poor, and shows that although the organic matter yield is high in warm environment, the degradation speed is faster, so that the modern peat is more easily enriched in cold soil zones. On the other hand, the large or shallow lake has no strong reason for the small and deep lake, because the thermocline formed by the small and deep lake can exist stably for a long time, and the thermocline of the large lake is easy to be damaged by convection.
After intensive research, the inventor finds that in the degradation-mineralization process of organisms, the higher the temperature of a deposition area is, the higher the degradation speed of organic matters is, the less the organic matters remain in the sediment, and the facultative anaerobic microorganisms play a key role. Meanwhile, organic matter degradation enrichment experiments carried out by an earth early environment simulator 'Paleobond' which is unique at home and abroad and used for exploring biodegradation and mineralization of organisms find that the organic matter enrichment of the small water body has the following characteristics:
in the first and the same water body, the temperature of the sedimentation area is a key factor for controlling the storage of the organic matters after sedimentation, the temperature is too high, the sedimentation amount is obviously reduced, the organic matters are decomposed by microorganisms, and the generated carbon dioxide returns to the atmosphere. And the low-temperature environment obviously enriches and stably stores organic matters, and the decomposition capability of microorganisms on the organic matters is weak.
Secondly, the larger the temperature gradient of the deposition area is, the higher the organic matter enrichment intensity is.
Thirdly, the position of the thermocline and the size of the temperature difference between the top and the bottom are closely related to the enrichment of organic matters.
The inventor's experimental simulation also found that the relationship between the concentration of organic matter and the concentration of dissolved oxygen in water, which is generally presumed, is significant only at higher temperatures.
The inventors have found, based on the above theory and natural environment investigation and experimental simulation, that low temperature contributes to efficient carbon sequestration, prevents organic matter from decomposing into inorganic carbon (mainly carbon dioxide that can be returned to the atmosphere), but high temperature or warm environment contributes to carbon capture. Therefore, the inventor can construct an environment which is both high carbon capture and effective carbon burying by innovatively transforming the environment, and provides a large-scale and low-cost scheme for carbon neutralization.
In general, through experimental simulation of a laboratory, the inventor finds and verifies that the following creative findings exist:
firstly, sediments rich in organic matters can be stably stored for a long time in a low-temperature environment;
second, long-term geological deposits, including black shale, rich in organic matter are associated with low temperatures;
thirdly, effective stable carbon burial of the effective carbon sink requires low-temperature environmental support;
fourth, the carbon sink involved in carbon neutralization must be such that the buried organic carbon does not decompose in a predictable time.
And fifthly, the stable thermocline, particularly the water bottom stable thermocline is the key for stably burying organic matters or forming black shale.
The invention mainly relates to the following technologies by referring to the earth environment of the coke period and on the basis of experimental simulation and research of a biodegradation mineralization mechanism:
firstly, driving a land lake, a marsh, a reservoir and the like to carry out temperature stratification with large temperature difference by utilizing atmospheric temperature and sunshine;
secondly, a driving technology for constructing and stabilizing a water bottom thermocline enables a low-temperature area of a deposition area to exist stably for a long time, so that decomposition of organic matters in sediments can be prevented, and carbon fixation products are prevented from returning to the atmosphere;
and thirdly, the technology of driving the warming environment of the photosynthesis area improves the carbon fixation capacity of organisms.
Fourth, large-scale low-cost ecological carbon neutralization technology: by utilizing the water body convection mechanism and the organic carbon sequestration environmental requirement of photosynthesis, the water body thermocline characteristic is established and controlled by controlling the water body directional convection and the limited convection, so that the organic buried environmental temperature is reduced, and the water body temperature in the photosynthesis area is increased to improve the carbon sequestration efficiency.
FIG. 1 is a temperature jump graph of a still water environment and a convection environment. As shown in fig. 1, after intensive research and simulation experiments, the inventors found that an organic matter deposition area in a low-temperature environment with convection suppression forms a highly stable thermocline system with a normal water body, and a key thermocline structure of the system has similar thermocline structures in a still water environment and an environment with convection, so that a stable low-temperature environment and a thermocline system can be formed at the bottom of a normal natural water body.
Therefore, the system can be constructed based on naturally formed land water bodies, such as lakes, marshes and the like, can also be constructed in artificially constructed land water bodies, such as reservoirs and the like, and can also be constructed after the naturally formed land water bodies are artificially excavated and expanded. FIG. 2 is a schematic diagram illustrating a system for enhancing carbon sequestration capacity of aquatic organisms according to an embodiment of the present invention.
FIG. 2 is a schematic structural diagram of a system 100 for enhancing carbon sequestration capacity of aquatic organisms according to an embodiment of the present invention. As shown in fig. 2, the carbon sequestration capacity enhancing system for aquatic organisms includes a high-temperature water body 10 located at the upper portion, a low-temperature water body 20 located at the lower portion, and a transition water body 30 formed between the high-temperature water body 10 and the low-temperature water body 20. The high-temperature water body 10 is provided with a top thermocline stabilizing mechanism 11 and forms an upper reinforced thermocline 12, and the top thermocline stabilizing mechanism 11 divides the high-temperature water body into a plurality of reinforced solid carbon areas 13. The low-temperature water body 20 is provided with a bottom thermocline stabilizing mechanism 21 and forms a lower reinforced thermocline 22, the bottom thermocline stabilizing mechanism 21 divides the low-temperature water body 20 into a plurality of reinforced carbon embedding areas 23, and a transition water body 30 is formed between the high-temperature water body 10 and the low-temperature water body 20.
The system of the present invention converts carbon dioxide in the atmosphere and dissolved inorganic carbon (including carbon dioxide) dissolved in water into organic matters through photosynthesis by aquatic organisms such as algae, aquatic plants, and photosynthetic microorganisms, wherein the upper enhanced thermocline 12 enhances the efficiency of photosynthesis, and organisms rich in organic matters settle down to the bottom of the water after death or during life into the lower enhanced thermocline 22. In general water bodies (lakes, reservoirs and marshes), the upper high-temperature water body and the bottom low-temperature water body formed by sunshine are generally influenced by the flow of the water bodies, and deposited organic matters are carried to other places by underflow, however, the invention prevents the flow of the water bodies by arranging the bottom thermocline stabilizing mechanism 21 and the top thermocline stabilizing mechanism 11, avoids the damage of the established water temperature environment condition which is beneficial to improving the carbon neutralization efficiency, and improves the photosynthesis efficiency and the carbon sequestration capacity.
Specifically, the upper water temperature rises under the sunshine effect, and top thermocline stabilizing mean 11 has prevented upper rivers and wave action to the disturbance of upper heating water body, constitutes and strengthens thermocline 12 on for the upper water body hardly takes place the convection current with whole water, thereby forms the stable high temperature water in upper photosynthesis district, is favorable to improving photosynthesis efficiency, improves the solid carbon efficiency who strengthens solid carbon district 13 promptly.
When the organic matter formed by photosynthesis, i.e., the primary productivity product, is formed, it sinks or is dead and sinks, and enters the lower enhancing thermocline 22. There are three basic pathways for the organic matter in the lower enhanced thermocline 22: first, complete decomposition; secondly, most of the decomposition is carried out; third, basic retention. When the temperature of the organic matter deposition area, namely the lower strengthening thermocline is lower, microorganisms playing a main role in degrading organic matters are slowly propagated, and the decomposition speed of the organic matters is relatively slow. Therefore, the organic matter in the low-temperature environment is retained for a long time and becomes a stable organic matter with general geological action or shallow metamorphism such as carbonaceous shale, kerogen, asphaltene and the like in the later geological process, thereby forming a stable and long-term effective carbon sink. For example, organic-rich sediment sinking to the low temperature environment of the low temperature sub-stratosphere will be stabilized in the form of peat, and will not be rotten, degraded and lost. The low-temperature environment in the low-temperature water body is acted by the bottom thermocline stabilizing mechanism 21, and forms a lower enhanced thermocline 22 with the low-temperature water body, and the lower enhanced thermocline 22 ensures the long-term existence of the underwater low-temperature environment and improves the carbon burying capability of the enhanced carbon burying area 23.
Alternatively, when the peat in the intensified thermocline at low temperature is full, the peat can be harvested for reuse as an energy source, and can also be sequestered for a long period of time.
In one embodiment, to prevent organic matter from decomposing in the low temperature body of water in the lower enhanced thermocline, the temperature T of the low temperature body of water in the lower enhanced thermocline isIs low inThe following relationship needs to be satisfied: t isIs low with≦ 15 ℃. Preferably, the temperature T of the low-temperature water body of the lower enhanced thermoclineIs low inThe following relationship is satisfied: t at 4 ℃ ≦ TIs low in≦15℃。
FIG. 3 is a schematic perspective view of a top and bottom thermocline stabilizing mechanism according to one embodiment of the present invention. As shown in FIG. 3, in one embodiment, the top thermocline stabilizing mechanism 11 includes a plurality of first blocking plates 111 arranged in a staggered pattern to dampen convection and waves. Alternatively, a plurality of first barrier plates 111 are arranged in a staggered manner in the lateral and longitudinal directions, respectively, and form a grid-like structure. In one embodiment, the top end of the first barrier 111 is higher than the high temperature water 10 by a distance LTop roof，LTop roofHeight H of water surface wave of high and high temperature water body 10Wave ofThe following relationship is satisfied: l isTop roof≧HWave of。
Set for top thermocline stabilizing mean's size and structure through the relation in above each embodiment, can make top thermocline stabilizing mean 11 can prevent more effectively that upper rivers and wave action from to the disturbance of upper strata heating water body, strengthen the thermocline on constituting for upper strata water body and whole water hardly take place the convection current, thereby form the stable high temperature water body in upper portion photosynthesis district, be favorable to improving photosynthesis efficiency, improve fixed carbon efficiency promptly.
Furthermore, it should be noted that, although the top thermocline stabilizing mechanism 11 shown in fig. 3 is composed of one layer of the first blocking plates 111 arranged in a staggered manner, in other embodiments, the top thermocline stabilizing mechanism 11 may also be composed of multiple layers of the first blocking plates 111 arranged in a staggered manner, that is, for some special geographical locations and geographical environments, multiple layers of the first blocking plates 111 arranged in a staggered manner may be disposed in the high-temperature water body 10, so that the top thermocline stabilizing mechanism 11 can more effectively prevent the disturbance of the upper-layer heating water body by the upper-layer water flow and wave action.
With continued reference to fig. 3, in one embodiment, the bottom thermocline stabilizing mechanism 21 comprises a plurality of second blocking plates 211 arranged in a staggered manner for attenuating convection and waves, optionally, the plurality of second blocking plates 211 are arranged in a staggered manner in the transverse direction and the longitudinal direction, respectively, and form a grid-like structure. The bottom thermocline stabilizing mechanism 21 is set according to the relation in the embodiments, the water convection of the lower enhanced thermocline 22 is effectively prevented, the long-term existence of the water bottom low-temperature environment is ensured, and therefore a stable and long-term effective carbon sink can be formed.
It should be noted that, although the bottom thermocline stabilizing mechanism in the embodiment shown in fig. 3 is composed of a plurality of second blocking plates 211 arranged in a single-layer staggered manner, in other embodiments, depending on the environment, climate, water flow and other conditions of the system, the bottom thermocline stabilizing mechanism 21 may also include a plurality of second blocking plates 211 arranged in a multi-layer staggered manner, that is, the plurality of second blocking plates 211 form a multi-layer staggered grid structure, so as to reduce the convection of the low-temperature water body at the lower enhanced thermocline, ensure the long-term existence of the low-temperature environment at the water bottom, and form a stable and long-term effective carbon sink.
