摘要
生物法除铁锰理论是对地下水接触氧化法除铁锰工艺中过滤单元氧化过滤机制的新认识,在不改变接触氧化法工艺的基础上,形成了以培养和维护滤层中铁锰细菌氧化过滤水中铁锰机制的地下水生物法除铁锰新工艺,以进一步改善除锰效果,降低工程投资及运行费用,是目前该领域具有广阔发展前景的工艺。主要介绍了生物法同步除铁除锰机理,生物滤层中铁锰的氧化还原关系,Fe2+的作用和对除锰的影响,阐述了影响生物除铁除锰技术主要因素的研究现状,分析了复合型微污染地下水处理存在的问题。
The theory of removing iron and manganese by biological method gives new understanding to oxidation filtration mechanism of the filtering unit for removing iron and manganese by groundwater contact-oxidation process, a new technique for removing iron and manganese in the groundwater on the basis of culturing and maintaining iron-manganese bacteria is formed to improve the effect of iron and manganese removal and decrease engineering investment and operation cost. In this paper, the mechanism of synchronized removal of iron and manganese by the biological method was introduced; the redox relationship of iron and manganese in the biological filter layer was discussed as well as FeE＋ function and its influence on removing manganese. In addition, study status on main factors to influence iron and manganese removal with biological technology was summarized, and current problems about treating composite micro-pollution ~roundwater were analyzed.
