A system for reducing biofouling on underwater surfaces of solid objects

Abstract

The present invention provides a system for reducing the biological attachment on the underwater surface of a solid-phase object. The system comprises: an insulating surface formed on the underwater surface of a solid-phase object; two electrodes fixed or formed on the insulating surface, wherein the two electrodes are mutually isolated and are electrically insulated; an insulating organism attachment layer at least formed on the two electrodes; and a power supply source, wherein both poles of the power supply source are respectively and electrically connected to the two electrodes through conduction wires, the power supply source supplies powder for the two electrodes, and the two electrodes generate an electric field so as to prevent the microorganism attachment and / or biological film forming on the underwater surface of the solid-phase object. According to the present invention, the system has advantages of no toxicity, no harm, environmental protection, low cost, good universality and good popularization and application value, and does not require energy source load.

Description

technical field [0001] The invention relates to the field of anti-biological adhesion, in particular to a system for reducing biological adhesion on the underwater surface of a solid-phase object. Background technique [0002] Biofouling has always been a major problem causing loss and invariance in water production and activities. Biofouling is a general term for the phenomenon of biological attachment to the bottom of ships, buoys and all artificial facilities. Periphyton is a complex community including sessile organisms as the main body, which has a wide variety, including bacteria, adherent diatoms and many large algae, as well as various phyla from protozoa to vertebrates. [0003] After the solid surface is immersed in seawater, a layer of organic matter will be enriched within ten minutes, and then microorganisms such as bacteria and diatoms will successively attach and grow on this layer of organic matter, forming a layer composed of water, organic matter, microorg...

Problems solved by technology

[0006] However, the above two methods have high cost, unstable anti-adhesion efficiency due to factors such as water temperature and ship speed, and only target a few specific adherent organisms, poor universality, and also have disadvantages such as energy load.
