摘要: 对当前珊瑚礁恢复技术进行了分析,提出了利用MICP技术对珊瑚礁生态恢复,并通过室内试验探究了不同菌液浓度和钙离子浓度对胶结效果的影响。研究结果表明:MICP技术可以应用于珊瑚基质胶结,菌液浓度和胶结液浓度对胶结的效果影响较大,合理的钙离子和细菌浓度有利于增强结构的胶结效果,降低孔隙密度,提高材料的均匀特性。

Abstract: The State-of-The-Art coral reef restoration methods are reviewed. The coral reef ecological restoration is proposed by using MicrobialInduced Calcite Precipitation (MICP) method. The effect of different concentration of various bacteria solutions and concentration of calcium ion on the cementation result are laboratory investigated. The results indicate that, MICP method can be used in the ecological restoration of coral reefs. The concentration of bacteria and cementation solutions have a significant impact on the cementation results. Appropriate concentration of calcium and bacteria will results in a lower porosity in the coral material and improved material uniformity.
