² 研究领域与专长：

主要研究领域为环境工程处理技术之序自动监控(monitoring and control)与操作效率之优化(optimization)为主。近年来各种不同原理的废水处程序被研发并应用于处理不同类型之家庭及工业废水，但如何让这些程序能经济、有效又具在线监测(on-line monitoring)与自动/实时控制实时控制(real-time control)而使废水处理程序达而使废水处理程序达到操控之优化(optimization)是最有效之方式ㄧ。因此，近年来国内外于废水处理程序之自动监控与程序之优化方面研究越来受重视。然而，国内环工界对这方面的研究相显得零散而缺乏对这方面的研究相显得零散而缺乏，本研究团队为国内少数研究团队为国内少数历经二十年以上时间持续投入于此方面之研究团队ㄧ，且具有相当成效于此方面之研究团队ㄧ，且具有相当成效，对相关技术之学术与实务领域具有相当贡献。

本研究团队于环境工程处理程序之自动化监测与优化控制之研究领域上已成功开发出多项监测技术并应用于多种处理程序之控制上，包括：SBR 生物除氮除磷系统之自动监控(NSC84-89)、废水消毒程序(加氯消毒及UV消毒)之自动监控(NSC90-92,93-94)、自来水混凝程序之自动监控、应用数字影像分析技术监测肺水色度与SS及化学混凝与沉淀之自动监控(NSC92-95，98)、Fenton系列程序之自动监控(NSC95-97)、奈米零价铁(NZVI)处理程序之自动监控(NSC99-101)。

另依研究主题与对象之不同，兹分别将主要之研究领域与成果说明如下：

A.　消毒程序(加氯及UV/UV-TiO2消毒)之自动与优化监控之研究：

加氯消毒(chlorination)为废水处理单元程序中常用且不可或缺的处理程序之一，但由于废水中均含有不同且变动之耗氯还原性物质(以氨氮为主)。传统以经验为导向之加氯控制方法，无法提供实时(real-time)之信息，作为消毒程序之自动控制之需要。由本人之研究发现，在利用加氯与除氯自动滴定系统实验中连续监测之ORP及pH曲线中，ORP曲线上发现两个波峯(peak)，另外，在pH曲线上则出现一个膝部(knee)及谷底(valley)，此两点出现之位置也都与废水中含有之主要耗氯物质(氨氮)浓度成线性关系。藉由此研究发现，可推算出消毒所需之实际加氯量，提供为废水加氯消毒自动控制之基础。此发现在国内外文献中并未见有相类似之研究，应该为国内外首见，另结合类神经网络之控制亦可达良好之控制效果。此研发之自动监控技术已经成功申请一项发明专利，另也技术移转给相关之业界。

UV消毒属于物理消毒法，具有不需外加化学药剂、消毒反应时间较短且设备载运及操作较安全等优势，在考虑废水回收再利用的水质安全上，应是目前最具有潜力应用于小型小区废水在利用的消毒方式。唯影响UV消毒之因素颇多，包括SS浓度、穿透率等，其中因废水本身复杂多变的特色，使在监测及操控上自然存有不确定性，故UV消毒之自动监控技术之发展并不多，因此无法建立UV消毒之最佳控制策略。本研究以符合水资源回收再利用之标准下，探讨并尝试建立UV消毒之自动监控技术，以简易型在线(on-line)光谱仪作为主要监测仪器，并加入具有除菌等功能之TiO2，以利增加UV消毒之效率，在监测 UV 强度，及建立原废水水质参数之相关信息，利用类神经网络进行仿真废水中SS、浊度、pH、温度、ORP、色度、及UV光强度、停留时间、UV剂量与残余大肠杆菌群等关系后，有良好的相关性，并进一步发展UV消毒处理控制程序，建立UV消毒之优化控制(optimal control)方式，以提高UV消毒效率与操作成本。

B.　应用数字影像分析技术监测废水色度与SS及化学混凝与沉淀之自动监控：

数字影像分析(digital image analysis)为发展快速且相当经济之技术，申请人之研究团队将此技术发展最为水及废水之水质监测与过程控制上，数年来发展了多项具有创新之技术。分别可自动监测废水之真色色度、悬浮微粒粒径、形态特征(碎形维度)、SS浓度，并利用此技术发展为自来水及废水混凝沉淀之过程控制，有效控制及掌握了加药量、停留时间及评估放流之SS与浊度。相关成果说明如下：

目前废水色度之检测方法以ADMI之3波长与31波长法为主，此两种方法并很难实时监测以提供作为色度去除之自动控制用，本研究尝试使用数字摄影机拍摄样品之彩色影像，并分析影像之RGB值，由RGB值计算出XYZ三刺激值(tristimulus values)，再经由转换计算真色色度值，成功地发展真色色度之自动监测方法。另外ADMI之3波长与31波长法之计算值会因色系之不同而产生颇大之差异，本研究以类神经网络建立新的计算模式，利用新的4及6波长法，该模式可解决此问题，此计算模式有潜力可取代原有标准方法之复杂计算方式，是一大突破。

申请人研究团队亦同时发展利用数字影像分析同时监测水中悬浮微粒之粒径与其型态特性之技术，可成功监测悬浮粒径在10um以上之粒径，该方法之监测结果与已商业化之雷射粒径分析仪之分析结果十分接近，但因其可以连续监测与且十分便宜的经济上的诱因，在化学混凝过程控制上具有非常高之应用价值，甚至取代昂贵的雷射粒径分析仪。本研究团队进一步将其应用于废水及自来水(参与本系郑文伯教授之研究为主)之化学混凝沉淀控制上。尝试利用在线影像分析技术发展一种具经济性且简便之化学混凝沉凝控制技术，利用监测之颗粒粒径、面积、体积大小及碎形维度(Fractal dimension)，结合沉淀固体通量之理论发展一套自动实时技术，此技术可对废水化学混凝沉淀程序之自动控制十分有帮助，可节省相关之操作成本。

C.　Fenton系列处理程序之自动化与优化研究：

近年来国内外有许多学者将染料/染整废水以多种高级氧化程序(Advanced Oxidation Processes，AOPs)之方式处理，Fenton系列程序(由Fenton、Photo-Fenton、Electro-Fenton等组成)以亚铁离子催化过氧化氢产生大量氢氧自由基(OH・)，破坏带色团之键结，应用上具有高效率、低操作费等优点。本研究旨在探讨利用Fenton 系列程序处理染整废水之自动监控技术之研发。由于ORP 应用于废水处理系统自动监控之研究已有许多成功的应用，而Fenton 程序所产生之OH‧具有相当强之氧化力，反应过程中ORP 随着过氧化氢增加而上升，应可有效地利用于氧化脱色之控制，因此本研究探讨利用ORP 作为控制参数之可行性，建立Fenton系列程序去除色度之自动化与优化控制技术，同时利用以类神经网络仿真ORP与 pH、Fenton试剂、色度去除率、原废水色度值与处理后残余色度等组合之关系，皆有非常良好的相关性，可应用此关系式发展Fenton系列程序之控制。将所建立的Fenton 加药量控制程序，设立各种不同色度去除目标，先以类神经网络分析的方式推算出各别加药量，将所推算加药量进行实验，以验证是否符合原先设立色度去除目标，并以目标值与实际值分析其相关性。本研究团队分别针对Fenton、Photo-Fenton、Electro-Fenton三种程序建立以ORP、pH、DO为基础之监测与程序控至技术。由相关实验之控制验证实验结果显示，控制目标与实际之加药量相关系数R2均可达0.93以上。由上述研究结果显示以各种加药量控制程序所推算加药量皆可处理至设定之目标范围内。

D.　奈米零价铁(NZVI)废水处理程序之自动监控：

E.　奈米零价铁(NZVI)废水处理程序之自动监控：

奈米零价铁金属(Nanoscale zero-valent iron, NZVI)具有强还原性，为近几年来新兴的废水处理技术之ㄧ。由于铁于地球上的蕴藏量仅次于铝，量多所以便宜且容易取得，并容易被再回收及再利用，且对污染物产生还原反应，不易造成二次污染，是一种高效率具潜力之废水处理程序。近年来，零价铁及更具效率之奈米零价铁的应用研究中被探讨于处理各类之工业废水如染料/染整废水、含氯有机物的脱氯分解、含铬等其他重金属废水、含硝酸盐废水、TNT及RDX火药等废水。然而利用奈米零价铁于处理水质变异性颇大之工业废水前处理有操作成本高与操控不易等问题，这些问题都直接或间接与加药量、pH之等控制、反应时间、中间反应等诸多因素有关，使得奈米零价铁程序操控不易，因此透过自动监测以实时控制其加药量、pH或停留/反应时间等操作参数，是一个降低操作成本及提升效率。本系列研究以奈米零价铁还原并结合后续之Fenton程序以处理不同的三种工业废水包括染整废水、含铬工业废水与含三氯乙烯工业废水等三种废水处理程序之自动监控技术。

由本系列研究发现，(1).以奈米零价铁结合Fenton处理染整废水程序中，反应中监测参数DO及ORP之变化量趋于平缓，可做为判断为奈米零价铁还原去色反应之控制时间点。还原阶段類神经网路中之倒传递類神经网路预测色度去除率分析R2=0.96。氧化阶段色度去除率预测R2=0.93。類神经网路中进行氧化阶段色度去除率分析R2=0.96。(2). 奈米零价铁结合Fenton处理TCE废水程序中。藉由监测参数的变化可以确定系统中还原反应的现象，pH迅速上升、ORP降为负值而水中DO值在反应3分钟内呈现厌氧状态，当三氯乙烯去除率达到平缓时，各监测参数变化量呈现稳定之还原状态。批次试验中，奈米零价铁可以迅速还原降解三氯乙烯，最终去除率可达到90%以上，各监测参数的变化会随着不同奈米零价铁剂量的改变而有所不同。利用多变量回归与类神经网络预测三氯乙烯去除率，类神经网络预测分析较多变量回归分析准确，其相关性系数可达0.98以上。由以上之研究结果显示，以监测ORP/DO/pH结合类神经网络对于三种不同之工业废水处理上，均可发展奈米零价铁过程控制之优化。

F.　环境信息系统之研究：

环境数据库，主要是将真实世界中的人、地、物等时空信息依自然环境、人文社经条件等背景基础数据，整合在一完整之环境数据库中。环境数据库之建立，不仅是支持环境保护工作的执行，更重要是要确保经济开发行为亦能永续顺利进行。环境数据库除能提供查询种种污染状况、环境指针与环境信息外，充分而完整的数据也可提供环境质量指针建构、环境影响评估、环境涵容能力推估、总量管制计划、各种攸关环境的预测推估模式及环保仲裁等等方面宝贵之依据及佐证之用的环境数据与数据。但相关之措施也要适切作用，才能使环境数据库的功能得以充分发挥。另建立综合性的环境评量指标体系需有两个前提，一、为环境数据库之充足与建构作业的持续，二、为指标体系本身需经妥善的研究以规划出最妥适的数据收集项目与范围；许多环境研究工作者经常反映台湾地区各门各类的所谓环境基本数据或背景数据的不足与可靠性的问题，为考虑环境评量指标体系之完备性与实用性，本计划之短中程目标在支持『永续台湾评量系统』与『永续台湾2011年』之基本信息需求，而长程目标乃为台湾成立一国家型的环境数据库管理权责单位，负责长期维护管理来自各个环境数据源庞杂的环境数据与环境信息，并且能提供政府管理决策、学术研究与一般民众查询使用。

本计划为国科会环境永续发展委员会的咨询委员提议优先推动的中心议题为建构永续台湾的愿景，其中包括三个主轴议题即(1)永续台湾2011，(2)永续台湾评量系统及(3)永续发展信息系统。此总计划即针对上述之规划而提出，由中央大学刘兆汉前校长为总主持人，共同主持人为中研院萧新煌教授、台湾大学叶俊荣教授及于幼华教授。三位共同主持人分别就上述三项主轴议题召集数字教授共同主持执行该部份之计划。本人为所参与为幼华教授主持之永续发展信息系统中由廖述良教授召集之污染防治组部分工作，负责河川及海洋环境信息之收集、诠释数据库（metadata database）之建置及数据质量管理系统之发展等工作。
