Coral cultivation device for lowering seawater acidity to promote growth of corals

Abstract

The invention discloses a coral cultivation device for using an ion exchange technique to lower seawater acidity to promote growth of corals, and belongs to the technical field of coral reef ecological restoration. The coral cultivation device comprises a floating ball, traction ropes, an immersible pump, a power source line, an ionic exchange resin storage, anion ion exchange resin, fixed rings,a concrete platform, pointed cones, shackles, water delivery pipes, water distribution pipes, latticed coral cultivation mediums and young coral plants. The coral cultivation device for lowering the seawater acidity to promote the growth of the corals is characterized in that the immersible pump is utilized to pump seawater with high acidity into the ionic exchange resin storage, and the processedlow-acidity seawater is delivered to the latticed coral cultivation mediums through the water delivery pipes and is uniformly drained through the water distribution pipes arranged inside the cultivation mediums, so that the seawater around the cultivation mediums is maintained at low acidity. The coral cultivation device which handles the problems of seawater acidification and accelerates the individual growth of the corals is provided in combination with the ionic exchange technique and a coral cultivation technique, and through the design, the partial seawater acidity can be effectively lowered, and ecological restoration work of a sea area in which coral reefs are degenerated due to the seawater acidification is accelerated.

Description

technical field [0001] The invention relates to the technical field of coral reef ecological restoration, in particular to a coral cultivation device adapted to acidified sea areas. Background technique [0002] For nearly a century, as the carbon dioxide content in the global atmosphere has continued to rise, the dissolved carbon dioxide in seawater has also increased correspondingly, resulting in a decrease in the pH value of seawater, and the problem of seawater acidification has become increasingly serious, affecting the survival of marine organisms and the balance of the marine ecosystem. serious threat. Coral reefs are formed by coral polyp skeletons composed of calcium carbonate during hundreds to thousands of years of deposition, and are widely distributed in tropical and subtropical shallow sea areas. Coral reefs are the most biologically diverse ecosystems in the marine environment. It is reported that hundreds of millions of people around the world depend on cora...

AI Technical Summary

Problems solved by technology

Relevant studies have shown that when corals are cultivated in acidified sea areas, the increase in seawater acidity reduces the calcification rate of reef-building coral polyps and the coral skeleton is vulnerable to erosion, and the growth rate of coral reefs slows down or even degrades.
