利用光學檢測分析技術建立基本、有效之光譜資料庫，以資料庫為基礎，發展水質定性與定量演算法，虛擬監測SS、COD濃度之量測技術，藉此達到即時水質監測，將來有助於未來即時水質監測系統建立之基礎。本研究主要探討污水處理業、染整業及印刷電路板業，所採得之廢水，經由水質檢測分析內容及比對光學檢測方法，去除相關之干擾，主要研究目的，在於將吸收光譜資訊應用於實廠之水質檢測，以此探討光學檢測方法於實際應用時可能遇上之問題，進而提出修正或建議。環檢所公告方法過濾SS孔徑為1.0 μm～1.5 μm濾紙，對於實廠光譜分析上，去除干擾的效果不佳，故本研究利用不同孔徑量測，以0.3 μm～0.6 μm孔徑濾紙過濾，可有效去除SS造成的干擾，得到與傳統分析之最佳多元迴歸的關係。結果顯示，在污水處理業放流水水質有各業別的混合水樣，所產生的干擾複雜性高，單去除SS干擾後其驗算SS及COD可與傳統分析相近，其演算方法是可行性。染整業因染劑的因素，每批次排放可能有不同色度的干擾，針對紫外光及可見光波段，經過過濾能將其SS所造成的干擾降低。印刷電路板業在光譜的干擾因子較污水處理廠及染整廠低，在建立方法上，可對全波段的顯著波峰做演算法可得最佳方法，其演算方法所得數據，可提供實廠廢水處理上參考依據，以提升各單元操作的處理成效。

　　Optical detection analysis technique is used to establish the basic and efficient spectrum database, based on which qualitative and quantitative algorithm for water quality and measurement technique for SS and COD concentration virtual monitoring are developed to achieve instant monitoring of water quality, and will be helpful for us to establish real-time water quality monitoring system. This study mainly aims to explore sewage treatment industry, dyeing-finishing industry and printed circuit board industry, from which waste water were sampled to remove the relevant interferences through water quality analysis contents and comparative optical testing method. Apply absorption spectrum information to full-scale water quality testing for research purpose in order to study the problems that may arise in practical application of optical testing method and put forward amendments and proposals. 1.0 μm～1.5 μm filter paper used for SS filtration aperture that was announced by Environmental Analysis Laboratory had poor effect on the removal of interferences. Therefore, this study based on the measurement in different apertures obtained the best relationship between traditional analysis and multiple regression by using 0.3 μm～0.6 μm filtration aperture to remove interferences caused by SS. The result showed that mixed water samples in effluent water quality of sewage treatment industry could be come from various industries, causing high complicated interferences. After only removal of SS interferences, the algorithm used for SS and COD checking computation similar to traditional analysis is feasible. The factor of dye in dyeing-finishing industry may cause the interferences of different chromaticity for each batch of discharge; UV-light and visible band could reduce interferences resulted from SS through filtration. Interference factor on the spectrum in printed circuit board industry is less than in sewage treatment plant and dyeing-finishing plant, and thus the best algorithm for significant wave crest in full-wave band can be obtained, enabling full-scale waste water treatment to use algorithm data as reference basis to improve processing results for each unit operation.
