Artificial reef body for electrically stimulating growth of hermatypic coral

Abstract

The invention discloses an artificial reef body for electrically stimulating growth of hermatypic coral. The artificial reef body comprises frame platforms, sacrificial anode blocks and coral hangers, wherein the frame platforms are made of carbon steel and a coating material, the coral hangers are mounted on the frame platforms, the sacrificial anode blocks are electrically connected with the coral hangers through the frame platforms, and the sacrificial anode blocks are spatially separated from the coral hangers. The sacrificial anode blocks and the coral hangers are preferentially subjected to galvanic battery reaction in seawater, and the coral hangers serving as cathodes subjected to oxygen uptake reaction, so that the concentration of OH<-> ions in the surrounding seawater environment is increased, HCO<3-> ions are converted into CO3<2-> ions, the concentration of CO3<2-> ions around the coral is increased, and calcification growth of the hermatypic coral is promoted; after the coral hangers are covered with CaCO3, MgCO3 and the like, the current consumption is reduced, and the sacrificial anodes can continuously provide cathode protection for the carbon steel frame platforms.

Description

【Technical field】 [0001] The invention relates to the technical field of coral reef ecological restoration, in particular to an artificial reef that electrically stimulates the growth of reef-building corals. 【Background technique】 [0002] Because of its extremely high biodiversity, the coral reef ecosystem is considered to have reached the upper limit of the development of marine ecosystems, so it is often dubbed "undersea garden", "oasis in the blue desert" or "tropical ocean in the ocean". Rainforest" reputation. In recent years, due to global climate change, human activities and the impact of harmful organisms, coral reef habitats have been seriously degraded. The slow growth of reef-building corals and the natural recovery process of coral reefs have greatly hindered the progress of coral reef ecological restoration. So people are starting to look at techniques to boost coral growth to speed up the recovery and rebuilding of degraded coral reef ecosystems. [0003] ...

AI Technical Summary

Problems solved by technology

[0009] Aiming at the problem of using expensive stainless steel to make artificial reefs in the prior art, resulting in high cost, the present invention provides an artificial reef that electrically stimulates the growth of reef-building corals, which has high anode utilization, low cost, and excellent corrosion resistance. The artificial reef body that can promote the calcified growth of reef-building corals can be used for coral reef ecological restoration projects such as large-scale coral cultivation and coral transplantation in coral reef degraded areas
