Description
Technical Field
The invention belongs to the technical field of microbial electrogenesis and fouling prevention and control, and particularly relates to a microbial electrogenesis research system and application of preventing fouling organism adhesion.
Background
The adhesion and mass propagation of micro or macro organisms in water on the components below the waterline can seriously affect the normal performance of the functions of the components, such as the biofouling seriously increases the navigation resistance of the ship, reduces the navigation speed, weakens the flexibility, increases the fuel consumption, accelerates the corrosion of a shell and the like. With the increasing frequency of human use of the ocean and exploration of marine activities, fouling by marine organisms has been a global problem that plagues marine workers.
Microbial films adhering to the surface of materials are an important factor in inducing biological corrosion of the material surface, and the adhesion of microbes is a highly spontaneous process which can cause corrosion of almost all materials, causing losses of up to hundreds of millions of dollars to production, transportation and storage facilities of the petroleum industry every year, and thus, the harm of microbial fouling is enormous. However, such biological damage has not been appreciated for a long time. With the rapid development of economy in China, marine engineering facilities such as marine oil production platforms, seawater desalination facilities, harbor facilities, ship equipment, seawater cooling engineering and the like are widely applied, and the problem of microbial fouling gradually draws attention to marine workers.
At present, marine scientists are actively controlling fouling organisms in various ways. Most commonly, the antifouling is carried out by using the toxic coating, although the toxic coating is the most effective means for preventing and controlling the biofouling, the use of the toxic coating seriously damages the ecological balance of the ocean and distorts the growth and development of a plurality of marine organisms, so that the use of the toxic coating is limited. Therefore, researches and developments of efficient and environment-friendly nontoxic antifouling methods are imperative.
The project is characterized in that through understanding of the biological characteristics and the adhesion mechanism of dominant species and with the help of the latest research results in the field of life science, multiple disciplines of physics, chemistry, material science and the like are combined, different discipline technologies are adopted for cross infiltration, and the biofouling prevention and control technology is cooperatively developed, so that the technology which can be accepted by the environment and can fundamentally and thoroughly solve the problem of biofouling is researched and developed, and the healthy continuous development of the marine industry and the fishery in China is promoted.
The project utilizes the microbial fuel cell technology of the residual waste oil of the ship, the technology of preparing OH & lt- & gt by coupling the nano seawater purification tank with anion exchange resin, the technology of coupling the microbial fuel cell with the nano seawater purification tank and the like to innovate the alkaline hydration film on the surface of the ship body, and aims to develop a novel microbial power generation device by utilizing the residual oil and the waste oil of the ship, and the generated micro-current is converted by chemical energy to ensure that a layer of strong-alkaline (pH is more than 9.0) hydration film is uniformly attached to the surface of the ship body. Since the adhesion organisms in the sea adhere by secreting acidic adhesive substances, OH-is generated on the surface of the ship body, and simultaneously, a large amount of oxygen contained in the water body on the surface of the ship body is consumed, so that the hydration film on the surface of the ship body is not suitable for the growth of the organisms, and the adhesion of fouling organisms is inhibited.
In order to promote interaction and unification of factors such as continuous development, ecological environment, human health and the like, the new fouling organism prevention and control method based on biotechnology and biological prevention and control means has extremely wide application and development prospect in the field of mariculture.
