  • 摘要: 采用KMnO4溶液浸渍法制备了新型改性锰砂滤料,研究了滤料表面性能和过滤处理高铁锰矿井水的效果。结果表明,锰砂滤料除铁锰性能优于石英砂、陶粒以及瓷砂,采用KMnO4溶液浸渍能够提高锰砂滤料的过滤性能,最优的浸渍浓度为5%。5%KMnO4改性锰砂滤料过滤处理高铁锰矿井水的最佳工艺参数为:过滤周期24 h,反冲洗强度3.2 L/(s·m2),反冲洗时间5 min;通过比表面积测试分析和SEM表征分析发现,KMnO4溶液浸渍能够提高锰砂滤料比表面积,并在锰砂滤料表面形成了氧化膜,从而提高除铁除锰效果,而且浸渍液浓度越高,这种作用越明显。
    Abstract: Modified manganese sand filers material was successfully prepared by impregnation with KMnO4 solution. It was studied at the surface characteristics and filtration performances by the treatment of coal mine drainage with high concentrated iron and manganese. The results showed that: refer to the performance of iron and manganese, manganese sand filter was superior to quartz sand, haydite, and porcelain sand. KMnO4 solution impregnation improved the filter performance of manganese sand filter and its optimal concentration was 5%. For the treatment of coal mine drainage with high concentrated iron and manganese by filtration process with 5% KMnO4 solution, the optimal parameters were filtration cycle of 24 h, backwashing strength of 3.2 L/(s·m2), and backwash time of 5 min. Through surface area test and SEM analysis, it was found that the surface area of manganese sand filter increased and oxide film on the surface was formed after impregnated by KMnO4 solution. This enhanced the performance of the manganese sand filter, the higher concentration of KMnO4 solution, the better performance of manganese sand filter.
