我国含铁含锰地下水覆盖人口超过3亿,地下水除铁除锰是供水常遇难题。20世纪50年代,接触催化被引入除铁除锰技术,提出铁质活性滤膜除铁和锰质活性滤膜除锰,能使二价锰在天然水质条件下被氧化去除。锰质活性滤膜除锰有化学机理和以后提出的生物机理。在实际应用中锰质活性滤膜自然生成比较实用;指出二价铁对锰质活性滤膜的污染及其对出水水质的严重影响;提出锰质活性滤膜生成前出水不达标的问题及解决途径;并对单级除铁除锰工艺进行风险分析,提出选择除铁除锰工艺的原则,并认为除锰在技术上不够成熟。
China’s iron-bearing manganese-containing groundwater covers a population of more than 300 million, groundwater iron and manganese removal is often the problem of water supply. In the 1950s, the catalytic contact was introduced into the iron and manganese removal technology, and the iron-based active membrane was proposed to remove iron and remove manganese from the manganese-based active membrane. As a result, the bivalent manganese was oxidized and removed under the natural water quality conditions. Manganese active membrane manganese removal has chemical mechanism and the biological mechanism proposed later. In practical application, the active membrane of Mn-based active membrane is more practical. It points out the pollution of Fe-Mn-active membrane caused by ferrous iron and its serious influence on effluent quality. Way; and single-stage iron and manganese removal process risk analysis, the choice of iron and manganese removal process principle, and that the manganese is not mature enough in technology.
