dc.description.abstract傳統混凝加藥常會有不足或過量之情形,本研究的目地,是評估利用光學偵 測方法來瞭解混凝後膠羽的特性,並將之應用於廢水混凝加藥控制上的可 行性.首先以數學理論推導來探討膠羽碎形維度與聚集數和其表面光學性 質間之關係,結果發現可利用光學偵測器的輸出值來定量這些膠羽特性.接 下來進行批次試驗,結果顯示PDA可有效監測廢水混凝行為並決定最佳加藥 量.而PDA的監測點以在快混之後即行監測較為適當.最後進行連續流試驗, 結果發現PDA的輸出值很穩定,並可反應濁度與加藥量對顆粒聚集的影響. The conventional method for determining the coagulant dosage leads to oor in realtime dosing control for the highly changeable quality of influent .In this study , we made some assumptions about floc size distribution and loght scattering properties of the fractal aggegates.With these assumptions, some quantitative informations of the fractal dimension and mean degee of aggregation were derived. The result indicated that the forward scattering light in the optical monitor may cause the diveations.zh_TW
