地表水锰污染在水处理中去除研究进展

Progress of Manganese Contamination Removal in Surface Water

近年来,我国地表水锰污染现象日趋严重,呈现出季节性、突发性的特点。其主要成因包括外来污染源、岩石土壤的条件、地下水补给和内源性污染。相比于地下水,地表水除锰的研究长期以来未受到足够重视,但可以借鉴较为成熟的地下水除锰理论和技术,主要有沉淀法、氧化法、生物法等。其中沉淀法较为简单,处理效果不佳;氧化法技术成熟,应用广泛;生物法环保高效,但大多尚停留在实验阶段,是重点研究方向;其他诸如离子交换法、膜过滤法、吸附法在应用中也都存在一定的局限性。

In recent years, China＇s manganese pollution of surface water is growing, showing seasonal and sudden. The main causes include external sources, rock and soil, groundwater recharge and endogenous contamination. Compared to groundwater, the research of manganese removal in surface water has not been paid enough attention. We can learn more theory and technology from manganese removal in groundwater, mainly precipitation, oxidation and biological treatment, where precipitation method is simple but poor to treatment, oxidation technology is widely used and biological treatment has more obvious advantages. Others, such as ion exchange, membrane filtration and adsorption also have some limitations in the application.
