The effects of oxygen supply in the rhizosphere on the eh ( oxidation reduction potential ) of soil and rice yield in planting troughs were studied , with the hybrid rice combination you 7954 as the material 摘要以雜交稻組合優7954為材料,研究根際供氧對稻田土壤的氧化還原電位及水稻產量和物質生產的影響。
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并刺激其活性外,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。
