【 摘 要 】

An artificial Stony Coral Reef Building System (SCRBS) was proposed as a new method for carbon sequestration in coastal area. The SCRBS is a proprietary technology developed by the authors of the present study. There are three steps of this method: the wave energy was transferred into marine current energy; electric power was generated from this current energy; and the artificial stony coral reef was created by the synthetic action of dissolved carbon dioxide and calcium ion under the promoting effect of low electric current in the seawater. In the process of creating stony coral reef, the carbon dioxide both in the atmosphere above sea surface and in the seawater was absorbed and sequestrated or semi-sequestrated. This method was validated in indoor experiments under heavy polluted environmental conditions. The results show it is highly efficient in reduction of carbon dioxide content in coastal environments.
