Title: | 結合鈣鹽沈澱法與電膠羽浮除法去除廢水中氟離子-連續式反應系統之建立(1/3) | Authors: | 駱尚廉 | Keywords: | 電膠羽浮除法;化學沉降法;氟離子;electrocoagulation;calcium precipitation;fluoride | Issue Date: | 31-Jul-2004 | Publisher: | 臺北市:國立臺灣大學環境工程學研究所 | Abstract: | 本研究以電膠羽浮除法結合化學沉 降法處理高濃度的含氟廢水。批式實驗之 結果顯示:(1)系統之電荷負荷應維持在 500 庫崙/升以上。(2)磷酸根太高會大幅影 響系統對SS 及氟離子的處理效率。(3)當 初始酸度接近氟離子濃度時去除氟離子 的效果最佳。 連續式反應實驗之結果顯示:(1)SDS 的濃度需在30mg/L以上。(2)流量需在200 ~600 ml/min 之間。(3)磷酸根離子的濃度 及pH 值仍對系統有非常大的影響。 Electrocoagulation and calcium precipit-ation processes are combined to treat high fluoride containing wastewater. Results from the batch experiments indicate: (1) the charge loading applied of the system should be over 500 coulomb/L to have a idea treatment efficiency, (2) high phosphate concentration leads to low removal of SS and [F-], (3) the optimum acidity is equal to the initial fluoride concentration. The results from the continuous system indicate: (1) the concentration of SDS should be over 30mg/L to have a idea treatment efficiency; (2) the flow rate should be in the range of 200 ~600 ml/min; (3) the phosphate and pH also influence significantly on the removal of SS and F-. |
