摘要

隨著我國生活水準增加，國民對於用水的需求和品質也同步提升。故相關用水標準也隨之提高，為了因應此趨勢，淨水廠對於自來水的處理或工業污水的再循環利用皆屬其中。本研究以生物碳及活性碳做為介質，經活化後，取活化後的生物碳之水樣降解甲基藍溶液，使用UV分光光度計觀測甲基藍(Methyl blue, MB)的吸光度值變化。並探討碳材活化後之水樣於有機染料廢水處理技術之應用，以及抑菌碳材之製備的可行性。結果顯示，吸光度確實有明顯的下降，活化後的水樣確實有使甲基藍產生脫色反應。反應速率為5min完成。使用不同碳材之水樣也有使染料脫色之效果。抑菌碳材部分結果顯示(1) 碳粉與鈦粉混合後與對照組濁度變化的比較，在7-8小時內確實有抑制生長作用。(2) 鈦粉與碳粉之比例在1:2以上，無論在D.I.或地下水都有顯著之抑制生長作用。載鈦碳製備最佳條件為四氯化鈦混合鹽酸製備，浸置時間為30 min.，整體的抑菌效果最好。

With an increase in living standards, the national demand for water quality must be simultaneously improved, which will also increase relevant water standards. One of the major trends for water quality improvement is the water purification plant for disposal or recycling of industrial sewage water. In this study, biological carbon and activated carbon were used as a medium. After activation, aquatic activated carbon samples were taken for degradation by methylene blue solution. UV spectrophometers were used to observe the absorbance value changes of Methyl Blue (MB). Water was allowed to traverse different types of activated carbon material, such as the application of organic wastewater treatment technologies, as well as the preparation of the feasibility of carbon material for inhibition. The results showed that there was a significant decrease in absorbance. Water samples allowed methylene blue to produce a decolorizing reaction after activation at a completed reaction rate of 5 minutes. Water samples using different carbon materials were also used to create an effect of the dye bleaching. Several results displayed bacteriostatic carbon material:
(1) After the toner is mixed with titanium powder, turbidity changes within 7-8 hours which inhibited the growth effect, compared with the control group.
(2) Regardless of growth, the ratio of titanium powder and carbon powder in a 1:2 ratio or more, showed a significant role in the inhibition of DI or groundwater.
The best preparatory conditions for carbon containing titanium tetrachloride mixed with hydrochloric acid was observed to consist of a dip set time of 30 minutes, which produced the best overall inhibitory effect.
