地下水除铁除锰技术评析

Analysis of Methods to Remove Iron and Manganese from Ground water

介绍了自然氧化法、接触氧化法、生物氧化法3种除铁除锰技术的工艺原理,论述了这几种工艺的运行效果及存在的问题;阐述了生物氧化法是针对自然氧化法、接触氧化法等常规技术存在的缺陷,并利用微生物技术提曲的一种经济高效、具有广阔发展前景的新工艺．指出由于理论研究与工程实践相对较少,生物除铁除锰技术还有待进一步研究与实践．

The principles of technology of removing iron and manganese from groundwater, such as natural oxidation, contact oxidation and biological oxidation, are introduced. The working effects and some problems existed are discussed. It is elaborated that biological oxidation is a economical, efficient and promising method, and is promoted. Owing to the faults the methods of natural oxidation and contact oxidation exist. Since the research and application of project is lacking of more researches and practices, the biological oxidation method must be further research and practised.
