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。 -
With the development of oil fields, many old reservoirs in the east of china enter the high water - bearing development period. sustaining a high and stable production rate faces severe challenge. the key to preserve oil output in high water cut period is dependent upon the understanding degree to the properties of residual oil distribution. from 1980 ' s, while the study of the reservoir flow unit was proceeded alongside, it has been more widely utilized to characterize reservoir feature and remnant oil distribution. study of reservoir flow unit plays. both theoretically and practically. an important role in recognizing reservoir heterogeneity. performing a high - definition reservoir delineation and understanding the distribution of the remnant oil in the reservoir
隨著油田的不斷開發，我國東部許多老油田已進入高含水期開采階段，保持油氣產量的穩定面臨嚴竣的挑戰，而高含水油田穩產的關鍵取決于對剩餘油分佈的認識程度。八十年代以來，隨著對儲層流動單元研究的不斷深入，它越來越廣泛地被應到油藏描述和剩餘油研究中來，流動單元研究對于認識儲層的非均質性、提高油藏描述精度、搞清剩餘油分佈具有重要的理論意義和實際意義。 -
In view of the poor thermal stability of polyoxymethylene ( pom ) induced by the residual catalyst and unstable end groups formed in the synthesis of pom. the pom was treated by amine, and the effects of the variety of amine compounds, treatment technology and water content on the thermal stability of pom were investigated ; the effect of triethanolamine on the thermal stability of pom was further studied by means of isothermal mass loss, isothermal mass loss rate, and formaldehyde emission amount
摘要針對聚甲醛由於合成中殘留催化劑及不穩定端基導致其熱穩定較差的問題，採用胺對聚甲醛進行處理，並考察了胺種類、胺處理工藝及水用量對聚甲醛熱穩定性能影響；採用等溫熱質量損失率、等溫熱質量損失速率、甲醛釋放量分析等方法對三乙醇胺對pom的熱穩定作用進行了進一步研究。
