Description
Technical Field
The invention relates to a technology for inducing marine periphyton to adhere and restoring ecological environment, in particular to an intelligent control device for promoting the induction and growth of marine periphyton.
Background
As the economy of coastal areas of China is rapidly developed in recent decades, and the development mode is extensive, the environmental protection is not emphasized; meanwhile, a large amount of domestic sewage and industrial wastewater are directly discharged into the sea, so that large-scale damage to coastal ecology is caused, and restriction on further development of coastal economy in China is formed. Meanwhile, the marine concrete engineering and the breakwater which are constructed in a large scale further destroy the fragile marine ecosystem. If necessary ecological protection measures are not taken immediately, the future losses will be enormous. Meanwhile, with the further development of economy, people prefer good ecological environment. Meanwhile, since the 21 st century, the global industrialization development is rapid, the consumption of fossil fuels is huge, and vegetation such as tropical rain forests and the like are cut down in large quantities, so that the global carbon dioxide emission is increased rapidly, the greenhouse effect is intensified, the climate is warmed, and a large amount of carbon dioxide is dissolved in seawater occupying seven tenths of the earth surface, thereby accelerating the ocean acidification process. Therefore, improvement and restoration of the current coastal ecological environment are very urgent.
At present, researches on oyster attachment aspects from different ions, cement types, calcium substances, substrate colors, substrate roughness and the like are carried out at home and abroad, and the researches are briefly introduced as follows:
ion: currently under intensive study, K + 、NH 4 + 、Ca 2+ And Cu 2+ In which K is + 、NH 4 + And Ca 2+ Has effect in promoting adhesion or metamorphosis of Concha Ostreae, and Cu 2+ The effect is not significant and at high concentrations, larvae are killed. But is generally not suitable for the actual marine concrete engineering due to the difficult implementation or high cost. The type of cement: concrete is very commonly used as a substrate material for adhesion of marine periphyton, and although newly manufactured concrete members, waste concrete and the like are adopted as repair substrates for some oyster reef repair projects, the effect is not ideal. The reason is that the Portland cement concrete is generally applied to the marine concrete engineering at present, but the high alkalinity of the Portland cement concrete can inhibit the attachment and growth of sessile organisms on the surface of the concrete to a greater extent. The concrete prepared by adopting the cement with lower alkalinity has a larger effect on improving biomass (mainly marine plants) sensitive to the alkalinity, and has a smaller effect on improving the adhesion amount and the adhesion density of the oysters. Calcium-based substances: the most commonly used calcium-containing substrates for effective induction of adhesion of oyster larvae are limestone and concrete. Through experiments, the cattle bone meal has stronger inducing ability to the adhesion of oyster larvae than calcium carbonate under the same conditions, andcalcium carbonate is almost equally inducible as calcium sulfate. Color: under the condition of low sea temperature, the dark bottom has the function of promoting the growth of oysters. Related research in China shows that oyster larvae are selective for color to some extent. Roughness: the results of the research on the adhesion of the roughness to marine periphyton larvae are inconsistent. On the premise of ensuring that other conditions are unchanged, oysters and barnacle larvae tend to be attached to rough surfaces more than smooth surfaces. However, on some other studies it was found that coarseness did not significantly alter larval attachment.
In order to restore coastal ecological environment, CN111264427A discloses a construction method of marine engineering, which can make oyster larvae quickly and densely adhere to the surface of concrete, and further, on the premise of achieving the basic goal of improving the durability of marine concrete engineering, simultaneously utilizes the characteristics of oyster as a marine ecological engineer, improves the capability of fixing carbon elements, reduces water body pollution and substrate pollution, and improves marine ecological environment. However, the precondition for the smooth implementation of the invention is that the physical and chemical environment of the sea area constructed by the marine concrete engineering is suitable for the growth and development of the oysters. Namely CN111264427A can not overcome the low pH value and Ca caused by ocean acidification in part of sea areas 2+ The problem that the living environment of the oysters is poor due to insufficient plasma quantity is solved, and the application field is obviously limited.
In addition, CN111302727A discloses a method for ecologically repairing underwater region of a breakwater in service, which comprises cleaning the surface of a marine concrete project in service, then coating a cement-based coating for inducing sessile organisms on the surface of the marine project, so as to achieve the effect of inducing oysters to rapidly and compactly attach to the surface of the marine project in service, and periodically monitoring plankton, nutrient substances and Ca in the region 2+ The nutrition barrel capable of being automatically controlled is arranged, so that the amount of plankton is enriched, and the calcium ion support is provided for the growth of the oysters. But the nutrient substances in the nutrient bucket are easy to lose along with the flow of the seawater when the nutrient bucket is thrown into the sea area, the ions of the substances in the nutrient bucket are not comprehensive enough, and the substances for neutralizing and acidifying the seawater are not placed, particularly the substances are releasedThe discharge rate is not easily controlled. Therefore, the problems of low pH value and poor living environment of the oysters caused by ocean acidification in part of sea areas cannot be solved.
CN111302727A has no further treatment proposal for the situation that the oyster attaching amount possibly existing in local engineering areas is small, but the ecological environment is entirely available, if the coating is coated on the concrete engineering or the rock in these areas again according to the method in CN111302727A, a great deal of time, manpower and fund are consumed, and thus the ecological system of the local marine environment is destroyed first, and the oysters are attached in a large amount to attract other organisms to attach, so that the ecological restoration needs a long time. And for the condition of slow degradation of marine ecology in local engineering areas, technical gaps still exist.
In summary, although the above researches are carried out, for example, biological calcium, inorganic calcium, dark substance and other ions are doped into concrete and paint for marine periphyton induced adhesion, so as to realize adhesion on concrete engineering and achieve the purposes of high durability and ecological restoration of concrete engineering. However, in the case where the ecology of the local sea area is good and it is not necessary to reconstruct the entire ecological system, the amount of attachment of oysters can be increased by appropriately changing the ions of the local sea area, thereby promoting the later growth of oysters, and the technology for reconstructing the environment of the complete ecological system is still insufficient. Particularly, the aspect of accurately controlling the release rate of the ions by using an intelligent monitoring technology. However, due to knowledge of related subjects such as marine organisms, marine microorganisms, marine chemistry, sensors and automatic control, the subject directions are different greatly, and multiple subjects and technical personnel are required to cooperate with each other to solve a plurality of problems.
