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-.application/pdf54686 bytesapplication/pdfzh-TW國立臺灣大學環境工程學研究所電膠羽浮除法化學沉降法氟離子electrocoagulationcalcium precipitationfluoride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)reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/22133/1/922211E002028.pdf
