摘要:
通常认为,磷是湖泊富营养化的主要限制因子,因此控制湖泊磷浓度和水平被认为是湖泊治理的关键.在外源磷输入得到有效控制之后,湖泊富营养化仍可持续几十年,这主要归咎于内源磷的释放.底泥原位化学钝化控磷技术因其操作性强、控磷效果明显,而被广泛作为湖泊内源磷的控制技术之一,而钝化材料的研发和应用是本项技术的核心.在世界范围内,研发了众多的用于底泥磷控制的钝化修复材料.本文主要梳理了国际上常用钝化材料的基本特性与研究近况,点明不同材料之间钝化效果的差异,并讨论了不同类型钝化材料的改性方法、钝化机制,分析不同环境因子对钝化材料稳定性的影响.论文最后探讨了原位化学钝化控磷技术与其他修复技术联用的污染控制效果及其可行性,并根据国际上钝化控磷技术的主要研究进展,提出钝化材料现阶段存在的不足,并对未来研究方向与应用前景进行展望.

Abstract:
It is generally believed that phosphorus is the main limiting factor of eutrophication, so controlling the concentration of phosphorus is considered to be the key to lake management. Lake eutrophication could continue for decades after the effective control of exogenous phosphorus input, due to the release of endogenous phosphorus from lake sediment. The technology of in-situ chemical inactivation of sediment is widely used as one of the control technologies of endogenous phosphorus in lakes because of its strong operability and obvious effect of inactivating phosphorus. The development and application of inactivation materials are the cores of this technology. Many phosphorous inactivation materials have been developed around the world. This paper reviews the research on phosphorus inactivation materials in lake sediment, including the following aspect:(1) The basic characteristics and research status of inactivation materials commonly used; (2) The differences of inactivation effect between different materials; (3) The modification methods and inactivation mechanisms of different types of inactivation materials; (4) The effects of different environmental factors on the stability of inactivation materials; (5) The effect of pollution control and feasibility of the technology of in-situ chemical inactivation combined with other remediation technologies. According to the main research progress of the technology of phosphorus inactivation, the shortcomings of inactivation materials at present are put forward, and the future research direction and application prospect are expected.
