武洛溪為高屏溪下游支流,長久以來因生活污水及畜牧廢水影響,河川污染屬性屬於嚴重污染狀況,武洛溪排水水質改善之研究有鑒於以往河川在受污染過程中已破壞原來之環境優勢,失去自淨功能,傳統水污染防治方法雖可去除或降低污染程度,卻也只能維持短暫之成效。遂利用近代推崇之生態工程-人工溼地觀念並結合「親水河岸」、「環境生態」、「景觀造型」、「休閒遊憩」等四類環境價值觀概念,建造一個兼利用性、社會性及教育性之城市河川環境。
本研究針對武洛溪排水水質改善工程進行後續監測工作,對水質、污泥重金屬、水文與生態作相關監測與調查,武洛溪排水水質改善工程目前為全省污水處理量最大之人工溼地,最大處理量可達50,000 CMD。其主要施工共分2期,第一期採自然跌落過濾法,藉由水躍作用增加溶氧並進行過濾及接觸式生物處理後流入兩座蓮花池進行第二次水質淨化。第二期則以3座FWS(自由水層流動系統)人工溼地進行水質處理,經由第一期礫石過濾床跌落曝氣、接觸式生物處理及第二期人工溼地自然淨化作用。
此外探討有機污染溪水經以跌水工法處理程序,本研究將武洛溪溪水以六階段跌水方式,藉由自然跌落與水躍作用以增加水中溶氧,加上礫石間間隙的物理性沉降過濾及接觸式生物處理程序,間接使微生物於好氧環境下進行生物代謝作用,進而淨化水質。此外經由連續3座FWS型人工溼地進行水質處理,對於生化需氧量(BOD)與氮生化需氧量(NBOD)處理效益,以及尋求推估生化需氧量與氮生化需氧量消耗量範圍簡易模式,透過本研究針對各單元水質、水量及生態調查監測,瞭解最佳操作參數、污染去除率,並進行武洛溪水體水質參數之反應速率常數建立,以期達成武洛溪排水水質改善工程最佳成效,同時經由創造多樣化環境及多孔隙空間之設計理念進行生態復育,並提供民眾休閒遊憩之環境,提供人工溼地處理污染河川水設計參考。
A downstream branch of the Kao-Ping Creek, the Wu-Lo Creek, by nature of river and creek, is regarded to fall under a state of severe pollution for how it has long been impacted by civil discharge and livestock wastewater. The Wu-Lo Creek discharge’s water quality improvement research, taking into account that rivers and streams have been deprived of their self-cleansing function for how their initial environmental advantages had been sabotaged in the pollution process, and that conventional water pollution prevention and treatment methods remained an interim remedy for how they only serve to remove or reduce the level of pollution, has adopted the increasingly popular eco-engineering and constructed wetland concepts, combining the four environmental value concepts of “friendly river banks”, “environmental ecology”, “landscape engineering”, “leisure and recreation”, to instill a practical, social and educational urban river/stream environment.

The study aims to conduct subsequent monitoring on the Wu-Lo Creek drainage water quality improvement project by implementing relevant monitoring and survey on its water quality, heavy metal content in the sludge, hydrology and ecology. The Wu-Lo Creek discharge water quality improvement project is presently regarded as the largest constructed wetland in wastewater processing volume island-wide, with a maximum processing volume reaching 50,000 CMD. With its major implementation divided into two phases, Phase one takes to a natural stacked-drop filtration, which utilizes hydraulic jump to increase the oxygen concentration and undergoes filtration and contact bioprocess before the water is fed to two lotus ponds for secondary water quality purification. Phase two utilizes three Free Water Surface systems to purify the water quality in the constructed wetland, which routes water through Phase one’s gravel filtration bed stacked-drop filtration, contact bioprocess and Phase two’s constructed wetland to derive the natural purification yield.

Also to examine the treatment method for organically polluted creek water using the hydraulic jump method, the study has utilized a six-step stacked-drop filtration method on Wu-Lo Creek water to increase the soluble oxygen in the water by using the natural stacked-up and hydraulic jump methods, coupled with the gravel’s condensation and filtration and the contact bioprocess, to excel indirectly the microbes to biosynthesis in an oxygen rich environment, and in turn to purify the water quality. In addition, the three FWS constructed wetland units are used in water quality treatment to derive the processing yield on biological oxygen demand (BOD) and nitrogen biological oxygen demand (NBOD), and estimate a simple model in defining the range of BOD and NBOD. By focusing on water quality and volume of various units and by relying on the ecological survey and monitoring, the study aims to discern a set of optimal operating parameters, pollution removal ratio, and to establish a constant reaction ratio on Wu-Lo Creek water quality parameters in anticipation of achieving an optimal yield on the Wu-Lo Creek drainage water quality improvement project. In the meantime, it also aims to achieve ecological rehabilitation by creating a diverse environment and utilizing the porous spatial design concept, offer the general public an environment of leisure and recreation, and provide references in the constructed wetland design fro treating polluted rivers and streams.
