碩士 / 國立雲林科技大學 / 環境與安全工程技術研究所 / 86 / In the 「climate change essential convention」 requests countries of the world to reduce the emission quantity of CO2, the biggest source of green-house gas, to the quality of 1990 before 2000, for preventing the disaster cause from climate change. Although the emission quantity in our country is still under the level now, but it will increase with industry developing and energy using, then we will be punished by other countries in International Trade business. The purpose of this study is using carbonate absorbed from heavy industries flue gas steam with base solution to cultivate Spirulina as carbon source, then it solved the green-house effect. The result point out that sodium salt is suitable for Spirulina growing, but the algae die by using potassium salt. The optimum cultural conditions list following: the optimum pH range : 8 ~ 10 the illuminate time : 24 hours a day is better the inoculate concentration : 0.15 ~ 0.25 optical density (560 nm) Sulphurous salts absorbed by base solution from SOx of flue gas show don't inhibit the growth of Spirulina. There is better growth condition of Spirulina at 4% sulfur content. Nitrous salts absorbed by base solution from NOx of flue gas show don't help Spirulina grow obvious and also don't inhibit its growth. There is better growth condition of Spirulina at 1% nitrogen content. The waste media after harvesting of Spirulina can serve as CO2 chemical absorber. After 3 min aerating by CO2, each liter waste media can absorb 6.55 L CO2, and recover aerating waste media for second cultivation. The growth of Spirulina by using recovery media is better than that using fresh one. Hence it can reuse the waste media and cultivate again.It is impossible to have 5.81×106 m3 reaction volume to treat 2500 million tons CO2 each year from NO. 6 Naphtha Cracking Plant by Spirulina, even by using high-efficiency bioreactor technology. The unique way to afford the huge treatment volume is to research novel bioreactor or to rise the CO2 utilizing efficiency by Spirulina.
