本研究係運用三角量測原理、朗伯-比爾定律、牛頓第三定律、流體靜力學與光學影像設備，以光學非接觸性量測技術，針對水質與水量等項目運用雷射光源、網路數位攝影機及數位影像處理技術，擷取及分析量測水面雷射光源投射光點距離與量測水樣散射光譜之機制與方法，發展可自動即時監測水位、水量、水中SS濃度等水體資訊。冀望研發一套功能完整的排放口水質與水量自動監測系統，以提供廢水處理廠管理人員、系統操作人員即時掌握與判斷處理系統功能穩定性，或裝設於特定廠商排放口，作為水質與水量處理費計算佐證工具，另亦可當作環保管理單位執行中之廢水處理廠排放口即時監測網路連線示範計畫之輔助工具。 研究成果之水量測驗證結果與真實水量之相對誤差為1.50%，已符合實廠設置功能需求，而SS量測誤差百分比依紅光源與綠光源測定結果分別為21.79%與25.11%左右，主要因量測水樣SS濃度偏低導致誤差偏高，如依光學影像推估值與標準方法檢測數據比對結果，證明本裝置於量測SS濃度具有一定程度的之準確性，未來經設備與方法改良即可提升量測準確性及穩定性，且再結合COD虛擬監測系統構築成一套多參數水質項目與水量即時自動監測系統，就可取代市面單一水質監測儀器，建立功能完整之自動操作系統並落實污染預防與整治管理工作。 This research uses the Triangle Measure Theory, the Beer-Lambert’s Law, the NEW ton’s Third Law, the Fluid Static’s and the optical image instrument. By using optical non-contact measurement technology, to gather and analyze the distance of laser light reflection location on measured water surface and scattering optical spectrum of measured water specimen, an auto- monitor mechanism of water level, water amount and water’s suspend solid percentage is developed. The research expects to invent a machine of integrated monitor function of discharge water amount and quality, which can support system operator of the waste water facility to control and measure capability of treatment system. The monitor machine can be set at an effluent location of specific factory so as to calculate the waste water management fee. The monitor machine also can be an assistant tool when acting the network monitoring plan of the environmental management agency at waste water Treatment facility’s effluent. It is found by the research that the relative error between measured and real water is 1.50%. The value already conforms to the demand of operating facility, Yet the measure error percentage for suspend solid of red laser and green laser is 21.79% and 25.11%. It’s mainly because the percentage of suspend solid water sample is too law so as to produce high error percentage. However, it is proofed by the data of standard method and the data of optical image analysis method that the device can accurately measure the SS value. It is convinced that with improvement of the instrument, and combination of virtual monitor system for chemical oxygen demand, the multiple real time auto monitor system can replace single water quality monitor instrument on market recently.
