脂質（lipids）包含脂肪（fats）、油（oils）與潤滑脂（greases）合稱FOG在廢水的處理中極為棘手。本研究的目的在篩選出具有高脂質分解能?的微生物，結合電凝系統的運用，以解決廢水中的脂質問題。本研究從飯店廢水處理系統的水樣中分?出16株菌株，測試其分解脂質的能力。結果發現A2、C1、C4、D2菌株具有分解Tween-80、-60、-40、-20的能力。C4與D2菌株對奶油、豬油與炒菜油同時具有分解的能力，但A2與C1對此三種油並不具分解的效果。此外，對奶油、豬油與炒菜油具有較佳分解能力的菌株為A3、B1、C3，然其對乳化劑不具分解效果。本研究挑選C4與D2結合電凝系統來處理廢水中的油脂，結果顯示C4與D2可降解電凝所收集的油脂。實驗結果顯示C4與D2菌株具有分解廢水中的乳化劑與三種油脂的潛力。本研究結合電凝設備與脂質分解微生物，提供了一套有效且具環保的廢水脂質處理方法，預期可幫助解決廢水處理系統對油脂的處理問題。 Lipids including fats, oils and greases (FOG) in wastewater are poorly removable by sewage treatment systems. The purpose of this study is to screen the microorganisms with high lipid-degrading ability and combine the electrocoagulation method to solve the problem of lipids in wastewater. Sixteen strains of bacteria were isolated from lipid-containing wastewater in the sewage treatment system of a plaza restaurant to test the ability of lipid degradation. The isolated strains A2, C1, C4 and D2 showed high ability to degrade Tween-80, -60, -40 and -20. C4 and D2 strains showed the ability to decompose cream, lard and cooking oil, however, A2 and C1 strains had no decomposition effect on these lipids. A3, B1 and C3 strains, which exhibited better decomposition ability for butter, lard and cooking oil, had no decomposition effect on the emulsifier Tweens. C4 and D2 strains were selected and showed the ability to degrade lipids separated from the wastewater using the electrocoagulation system. The results showed that the strains C4 and D2 have the potential to decompose the emulsifier and the three types of lipids in wastewater.d. This study combines a electrocoagulation equipment with lipid-degrading microorganisms to provide an effective and environmentally friendly method to treat lipid-containing wastewater, which may help to solve the problem of lipids in the sewage treatment system..
