公共給水現代化淨水操作監控及知識化資訊管理之示範建置計畫

Abstract

公共給水品質的提升與淨水場操作效能息息相關，本計畫透過自動化操作監控系統的開發，並藉由建構全方位淨水場資訊管理系統，強化操作資訊之知識化管理，方有助於國內自來水事業之發展及提升國際競爭力。 本計畫為三年計畫，第一年計畫已收集及彙整臺灣、美國及澳洲之淨水場單元操作監控技術、規範與單元操作之標準作業程序(SOP)，以及提出自來水工程設施標準之修訂原則及步驟，並建立了國內淨水場各項操作監控技術之背景資料，以及收集國內外操作檢測設備與檢測技術之相關法規及技術規範。在實驗室試驗上，已建置實驗室之混凝加藥監控技術，並初步完成29組不同濁度原水之混凝最適加藥量評估數據庫，實驗結果顯示混凝最適加藥量會隨原水濁度升高而增加，以及PDA與FICA系統均可應用於不同濁度(10~1,000 NTU)之地表水混凝監測。在模型廠規劃上，已完成傳統處理程序之模型廠之設計圖(含平面流程圖、P&I圖及高程圖、平面配置圖)。在資訊管理系統方面，已蒐集完成臺灣377座淨水場基本操作資料之收集，並初步完成全國現代化淨水場操作資訊系統雛形架構。

The performance of water treatment plant (WTP) is a crucial parameter for the enhancement of public water supply. The aim of this project is to develop an automatic operational system as well as a supervisory control system, especially in coagulation dosing control and backwashing operation control. Other approaches are to enhance knowledge based technology for operational information management via establishment of an omnibearing information management system, and to facilitate the development of public water utilities and their international competitiveness. This project will be conducted for three phases (almost three years) in total. In the first phase, operational as well as supervisory control technologies and corresponding standard operation procedure (SOP) for WTP in Taiwan, American and Australia has been reviewed and then categorized. In addition, the revision principle and procedure of the standards for water supply engineering facilities have been established. The basic background data of operational as well as supervisory control technology for WTP have been established. Meanwhile, the relevant regulations as well as technical manuals for operation have been surveyed. In the laboratory test, the monitoring set-up for coagulation has been developed, and the 29 data of optimum dosing for coagulation and parameters of raw water has been established. The results have shown that the optimal coagulant dosage increases with the increase in the turbidity of raw water, and either output of PDA or FICA system can be regarded as a decisive parameter for on-line monitoring the performance of coagulation for various turbidity water samples (10~1,000 NTU). In the design of pilot-plant, the conventional processes equipped with a smart operational as well as supervisory control system for rapid mixing and rapid filtration units has been plotted and designed, including treatment process, P&I, elevation diagrams and space layout. As to operational information management system, the operational data of 377 WTPs in Taiwan has been questionaire surveyed, and the framework of operational information system for modern WTP has been plotted preliminarily.
