| 10. | The effort of manganese removal was studied and the kinetics of manganese removal was tried to establish . the factors of dissolved oxygen concentration , fe2 + concentration , ph , p concentration and closing of the filter were studied to evaluate their effort for biological manganese removal , and the correlation of residual manganese and oxidation - reduction potential was also discussed . as the iron content of water was high , experiment results showed that the reaction was zero order , as the iron content of water was low , the reaction was first order . the time needed for the cultivation of biological manganese removal was 60 70 days . the filter operated at the filtration rate of 8 10m / h , silica sand of effective size 0 . 95 1 . 25mm filled the filter to a depth of 1200mm
试验结果表明,成熟后滤砂表面滤膜的x射线衍射图谱与mno _ x ? 5h _ 2o ( x = 1 . 86 )的x射线衍射图谱一样,滤膜成熟后的结构在进水物质不发生变化的情况下不发生变化;合适的碳磷比对生物除锰有明显的促进作用,试验条件下的投磷量不会对出水造成二次污染;生物除锰需要亚铁的参与,亚铁的存在除了能够促进微生物分泌胞外酶并刺激其活性外,还通过铁离子的变价传递电子,催化锰离子的氧化反应,从而促进对二价锰的降解。
