中文摘要 | 許多研究指出前臭氧具有提昇後續混凝沉澱程序之功能,亦即,前臭氧會改變所需混凝劑量、有機物去除狀況、及過濾水質等等。本研究針對澄清湖原水利用實驗設計法探討不同臭氧劑量與不同混凝劑量,對濁度、藻類、A254、葉綠素-a等重要水質參數之去除情形,期能獲得較為精確之控制操作參數。研究過程臭氧濃度控制在0.4~4.6 mg/L,而鋁鹽劑量則調整介於10~100g/L之間。結果顯示,針對不同水質參數會不同之最佳操作條作。濁度之混凝沉澱最佳條件為臭氧劑量1.0 mg/L、鋁鹽70~85 mg/L,藻類去除之最佳條件為臭氧劑量2.5 mg/L、鋁鹽70~85 mg/L,而葉綠素-a與A254則為臭氧劑量3.5 mg/L、鋁鹽70 mg/L。此外,澄清湖水質藻類數量與葉綠素-a濃度有某種程度之關係。 |
英文摘要 | The enhance of the function for coagulation-sedimentation by preoznation have been proved by many researchers. Preozonation could effect the coagulant dosage, the organic removal in coagulation and water quality of filtration. This research was to investigate the effect of various ozone dosage and coagulant dosage on the removal of turbidity, algae, A254, and chlorophyll-a by experimental design. Further, the optimum operation was expected to get in this study. To depend the present data, it indicated that the optimum operation was effected by the various parameters at 0.4~4.6 mg/L of ozone concentration and 10-100 mg/L of alum. For the turbidity removal and algae, the optimum alum and ozone concentration of former were 1 mg/L, 70~85 mg/L, respectively. That conditions of latter were 2.5 mg/L, 70-85 mg/L, respectively. Regarding the removal of chlorophyll-a and A254, it had the same optimum condition. It’s value was 3.5 mg/L of ozone and 70 mg/L of alum. Also, the count of algae and chloriophyll-a had good correlation in raw water of Cheng-Chin Lake. |
