【摘要】 饮用水除锰技术一直是饮用水水质保障技术领域的热点和难点。除锰技术的发展经历了化学氧化法、空气氧化接触过滤法和生物催化氧化法三个阶段。锰的微生物氧化机制较为复杂,除了生物酶外,生物锰氧化物的初级产物同样具有较高的吸附氧化活性,其微观结构和活性会随时间快速变化。对饮用水除锰技术中的氧化机理、锰氧化物的吸附氧化特征及可能的工程应用等当前研究热点问题进行了综述。更多还原

【Abstract】 The technology of manganese removal from drink water has been the focus and nodus in the technical field of water quality security of drinking water. The development of manganese removal technology has undergone three phases such as chemical oxidation method, air oxidation contact filtering method and biological catalytic oxidation method. The oxidation mechanism of manganese by microbial is more complex, in addition to biological enzyme, adsorption and oxidation activity of primary products of biogenic manganese oxides is also very high, and its micro structure and activity will change rapidly with time. The mechanisms of manganese oxidation, adsorption and oxidation capacity in the technology of manganese removal from drink water, and potential application in water treatment processes are reviewed.更多还原
