  2. Abstract : through analysis on the character and use of geothermal water, expatiate the mechanism of iron removal from geothermal water, adopt the iron removal and manganese removal technology of aeration full oxygen and savageness manganese grit osculate oxidation, and control the intention and time of inverse flush, these make the treated geothermal water reach the standard of iron and manganese chroma, moreover, it won ' t increase bad component or decrease good component it is a perfect iron removal and manganese removal technology that can save installation investment, need low operating cost and reduce the heat losing

    文摘:通過對地熱水的特點及其用途的分析，闡述了地熱水除鐵除錳機理，採用曝氣充氧、天然錳砂接觸氧化的除鐵除錳工藝，並適當控制反沖洗強度和時間，使處理后地熱水含鐵、錳濃度達到標準，且不增加有害成分或減少有益成分.設備投資省、運行成本低，熱損失小，是一種理想的地熱水除鐵工藝
  3. 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。
  4. " this new treatment works has been specifically designed to take advantage of the most advanced technologies, including clarification by dissolved air floatation units and removal of ammonia and manganese by primary aerated biological filters to produce high quality drinking water, " mr ko said. to conserve water, all wash - water used for regular cleaning of filters is recycled

    他說，大埔濾水廠在設計上採用最先進的技術，包括以溶氣浮選池進行澄清工作，以及使用初級曝氣生物過濾池消除水中的氨氣和錳，以提供優質的食水。
  5. The results showed : fiber ball has the highest efficiency among the three, its water - consumption is small in backwash and it is more wear - resisting ; the comprehensive property of quartz grain filter material is poorer ; manganese grain has an effective removal of fe ( superscript 2 + ) and mn ( superscript 2 + ) but water - consnmption is big

    結果表明纖維球濾料除鐵濾速高，反沖洗耗水量小且耐磨損；石英砂濾料綜合性能次之；錳砂雖然除鐵效果較好，但反沖洗耗水量大。
