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
試驗結果表明，成熟后濾砂表面濾膜的x射線衍射圖譜與mno _ x ? 5h _ 2o （ x = 1 . 86 ）的x射線衍射圖譜一樣，濾膜成熟后的結構在進水物質不發生變化的情況下不發生變化;合適的碳磷比對生物除錳有明顯的促進作用，試驗條件下的投磷量不會對出水造成二次污染;生物除錳需要亞鐵的參與，亞鐵的存在除了能夠促進微生物分泌胞外酶並刺激其活性外，還通過鐵離子的變價傳遞電子，催化錳離子的氧化反應，從而促進對二價錳的降解。 -
Such features can be ascribed to lower degrees of partial melting and greater melting depths. in particular, the decoupling between the lowest nag and highest tig tends to indicate residual jadeite during melting process so that na behaved as a moderately compatible element to lower the naao concentration in these rocks. this is consistent with the ree patterns in the high - ti diabases that have the highest ( gd / yb ) cn ratios than other two groups, which suggest a more important role of residual garnet in generation of the primary magmas
運用mgo = 8進行標準化，結合巖石成因理論討論了三大系列輝綠巖的形成相對深度和熔融比例，其中高ti系列的原始巖漿形成深度大，熔融比例小，源區相對最為富集易熔組分；低ti系列的熔融深度最淺，比例最大，源區相對虧損易熔組分；過渡ti系列則介於前兩大系列之間。 -
The residual manganese concentration of the groundwater treatment plants, which normally exceeds the limit of 0. 1 mg / l. based on the water sample of the laboratory of hunan university and by the aid of model experiment, the time needed for the cultivation of the biological filter were discussed, so were its affecting factors
考察了濾柱培養成熟的時間及影響生物除錳效果的因素;研究了生物除錳的機理，建立了生物除錳反應動力學模型;探討了磷、 fe ~ （ 2 + ）等因素對生物除錳的影響，同時還研究了錳的去除與氧化還原電位的關系，對濾膜的結構進行了測定。 -
