摘要: 
A water supply treatment plant with higher background values of Fe and Mn content was
chosen in this investigation to proceed on-situ pilot scale experiments. The raw groundwater was
firstly aerated by aeration tower and flocculated in retention tank at a selected constant pH value, then
the total and soluble concentrations of Fe and Mn in effluent from filtration process were monitored in
order to understand the removal efficiencies. The accumulated percentage of diameter distribution of
the flocculated particles was analyzed by a laser particle size analyzer to assess the effect of
pretreatment. Moreover, the type of filtration mechanism was proposed through the analysis curve of
filtration resistance in filter layer during filtration.
Based on the results of on-situ pilot scale experiments at Hua-Tan Water Supply Treatment Plant, a
good removal efficiency was observed at pH 9 and 60 minutes of retention time for Fe by quartz sand
filtration media without addition of any chemical agent. Similarly, 30 and 60 minutes of retention time
were both suitable for Mn.

本研究係針對地下水原水鐵、錳背景值較高之淨水場,進行實際淨水場現場原水
之模廠實驗,以獲得較實用的去除鐵、錳之相關操作依據。實驗內容主要為將現場未經處
理的地下水經曝氣塔曝氣,於停留池膠凝及經pH控制器調整pH,再經過粒狀層過濾後,由
出流水監測其鐵、錳之總量濃度與溶解量濃度,藉以分析整體的去除效率,並於停留池溢
流口取樣,以雷射粒徑分析儀分析溶液中膠體顆粒粒徑分佈之累積百分比,評估其前處理
的成效,而後再經粒狀層過濾去除膠羽顆粒,於過濾進行時藉由粒狀層的過濾阻力分析曲
線評估膠羽以何種型式的過濾方式為濾床所濾除。經由上述處理流程,以確立淨水場實際
原水之模廠試驗更實用之操作依據。
由花壇淨水場現地模廠操作結果顯示,由於實際原水所進行之實驗不若人工配製原水單純
及易於控制水質條件,初步的實驗結果顯示若不添加任何藥劑,採石英砂為濾料於pH=9.0
時,就去除鐵部份而言,選擇停留槽停留時間60 min可得到很好之去除率,而去除錳時選
擇停留時間30 min和60 min皆可得到很好之去除率。
