dc.description.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,初步實驗結
果顯示,在批式實驗中,當總鋁添加量小
於3mM 時,共沈澱系統的氟離子去除率
明顯優於吸附系統,且可以系統中總鋁添
加量與氟離子與鹼度相加量的比例OH+F
為主要的控制因子。在電動力學實驗中,
硫酸根離子的存在會對電膠羽浮除系統
造成最大的影響,OH+F 亦可作為主要的控
制因子;當氟離子為系統中主要離子時,
氟離子去除效率完全受電流所控制。當氟
離子不再為系統中主要離子時,氟離子去
除效率仍會受電流所控制。 | zh_TW |
dc.description.abstract | Electrocoagulation and calcium
preci-pitation are combined to treat high
fluoride containing wastewater. Results
indicate that the rate of fluoride removal in
coprecipitation system was better than that in
adsorption system when the total aluminum
concentration was less than 3mM in batch
experiment. A new parameter, the molar ratio
of aluminum and the sum of fluoride and
alkalinity (OH+F), is the key parameter of the
fluoride removal effecicency. In electric
kinetic experiment, the results indicate OH+F
can also be used as the key parameter and
sulfate affected the system most. The rate of
fluoride removal is only controlled by current
when fluoride is the dominating anion in
system. The rate is also affected by current
when fluoride is not the dominating anion in
system. | en |
