新型水处理材料海绵铁在废水处理中的应用研究

作为一种新型多功能水处理材料,海绵铁具有优越的物理化学性能。通过吸附、微电解、絮凝沉淀、直接还原和间接氧化等作用,海绵铁在水体去污的过程中显现了较强的处理能力。在总结海绵铁去除水中难降解有机物和重金属离子等污染物的研究现状的基础上,提出海绵铁在应用中存在的问题及改进方向。海绵铁与微生物在降解水体污染物的过程中存在互促作用,因而生物海绵铁体系有更强的处理能力,将成为海绵铁材料用于水处理的开发研究新方向。

Application of New Water Treatment Material Sponge Iron in Wastewater Treatment

As a new type of multifuncfional water treatment material, sponge iron has excellent chemo - physical characteristics. Through adsorption, microelectrolysis, flocculating settling, direct reduction, indirect oxidation and other role, sponge iron possesses positive capacities for removing pollutants from water body. On the basis of summarizing the research status quo of the removal of organic compounds and heavy metal ions from water with sponge iron, the disadvantages of the sponge iron and its optimization aspects during preparation process are discussed and summarized. Because sponge iron and microbes has mutual impetus in the process of removing pollutants from water body, biological sponge iron possesses positive capacities. Biological sponge iron will become the new direction of development and research of sponge iron in wastewater treatment.
