摘要

地球有73%為水所覆蓋，但97%皆是無法直接取用的海水，不含南極大陸及冰川淡水，實際可直接使用地表淡水僅有0.0018%左右。因環境變遷以及人類對於水資源的需求越來越大，水資源的問題越顯重要。
台灣雖位於非枯水區，但有80%降水量集中在每年5~10月的豐水期，且有46.2%降雨量直接流入海中，33.3%為蒸發散損失，可利用之水量僅佔降雨量之20.5%。除一般民生及農業灌溉所需，工業用水之用量占台灣總用水量的9.47%，如何有效回收經處理後的排放水再利用刻不容緩。
本研究以台灣某工業園區內某石化廠的二級處理排放水回收測試機組為例，使用灰色理論模型GM(1,1) (Grey Theory 1,1)進行二級處理排放水回收系統的反滲透膜(RO, Reverse osmosis)運行狀況進行預測分析，並結合運用水回收系統相關數據條件進行RO加壓泵浦馬達出力的模糊邏輯控制(FLC, Fuzzy Logic Control)模擬，用以有效提高水回收處理系統的使用效能。

Although 73% of the Earth we live in covered by water, but 97% of it is seawater and cannot use directly, among all surface water is only about 0.0018% for direct using. Because environment of Earth has been changed and human demand for water resources growing, the problems of water resources become more important.
Although Taiwan is located in non-dry areas, actually, 80% of precipitation is concentrated in the annual wet-season from May to October, and 46.2% of the rainfall flows into the sea directly, 33.3% of the evaporation loss, there is only 20.5% of rainfall water available for using. In Taiwan, except common people's livelihood and agricultural irrigation needs, industrial water consumption accounted for 9.47% of total water consumption. How to more effectively recycle and reuse treated water is an issue cannot wait.
In this paper, a secondary treatment wastewater reclaiming system of petrochemical plant is used for the example. The grey theory model GM (1,1) (Grey Modeling 1,1) is used to treat the reverse osmosis membrane (RO), using system relational data by fuzzy logic control (FLC) to simulate the motor running of RO boost pump and improve the efficiency of the operation for water reclaim system.
