台灣經濟規模快速發展，然而工業化與城市化對環境帶來重大壓力，特別是台灣都市土地腹地面積小，容易造成工業區污染很快就外溢到臨近住宅區。目前常用之水質監測設備雖然可靠度佳，但一些常用之監測器如：pH計、導電度計等需要人力定期校正與清洗，增加人力維護需求；而重金屬或化學需氧量等水污法重要收費水質項目則有相對設置經費較高、設備體積較大等缺點；因此，目前常用之監測儀器並不適用於大量設置或廣佈等應用情境。 本計畫共達成以下成果：1.利用光學與電化學技術開發酸鹼度、溫度、電導度、化學需氧量、懸浮固體物及重金屬之微型化水質監測元件並整合微流體系統、化學分析、光學偵測、訊號處理電路等技術，開發具有「體積小」、「耐用」、「維護容易」及「低成本」特性之小型自動化水質監測系統裝置，可應用於水中pH、電導度、SS、COD以及重金屬銅離子之濃度檢測，並已於指定場域完成100組即時水質監測系統設備布建，且水質感測設備經現場第三方比對查核100組各3次，數據品質滿意度可達89.9 %。2.布建於桃園市部分南崁溪流域、龜山工業區及坑子口圳之100套水質監測設備，已實際維運60日以上，水質監測數據之資料完整率達96%以上。3.完成水質物聯網無線通訊模組與資料中心系統並上線運作，且已建立布建維運管理系統及水質感測資料分析決策應用系統，可即時反應污染潛勢地區之水體品質並達到污染溯源及水質異常預警等功能。

Due to rapid development of economy in Taiwan, industrialization and urbanization have brought great pressure on environment. In particular, industrial pollution has immediate impact on residential areas because of location in the nearby areas. The conventional water sensing instruments, such as meters for pH and conductivity measurement are reliable. However, frequent manual calibration and cleaning are usually required, thus the manpower demand for maintenance is heavey. Also, monitoring instruments for regulatory items related to enforcement, such as heavy metals and chemical oxygen demand have disadvantages of large volume and high installation cost. Therefore, the conventional water sensing instruments are not suitable for application scenarios on widely installation and distribution. A compact, robust and reliable multi-task water monitoring instruments is needed for environemtal IoT applications. The project has achieved the following results: 1. Miniaturized water quality sensing components for pH, temperature, conductivity, chemical oxygen demand (COD), suspended solids (SS) and heavy metals by utilizing optical and electrochemical methods are developed. A small automated water quality monitoring system for detection of pH, conductivity, SS, COD and heavy metal featureing compact, durable, easy maintaineance and low cost is also developed by integrating microfluidic systems, chemical analysis, optical detection and signal processing circuits. 100 sets of the automated water quality monitoring system have been installed in the designated field. Each set of instruments on sites has been checked three times comparing to standard measurement methods by the third party and achieved 89.9 % of overall data quality satisfaction. 2. Up to now, 100 sets of water quality monitoring instruments have been installed on several sites of Taoyuan City, including part of Nankan creek River Basin, Guishan Industrial park and Hangzikou irrigation ditch. The systems have been operated continuously over 60 days and achieved 96% of complete transmission of water quality monitoring data. 3. The water quality IoT wireless communication module and data center system has been established and operated online. Combining the established deployment maintenance management system and water quality sensing data analysis and decision-making system, the platform can issue immediate alert on the Traceability and early warning for the potential pollution area.
