中文摘要：

酸性条件下，借助过渡金属的催化氧化性，可以将烟气中的SO2转化为S（Ⅳ），以Fe^2＋为能源，在繁殖过程中不断将Fe^2＋转化为Fe^3＋的T．f菌（氧化亚铁硫杆菌）引入脱硫吸收液以维持Fe^3＋浓度，从而获得较高的脱硫效率．对T.f菌的驯化以及微量营养物质的加入，是T.f菌发挥其功效的关键．

英文摘要：

With the aid of the transition metal catalyzed oxidability, SO2 can be transformated into S （ Ⅳ ） under the acidic condition. Because of the reduction of Fe^3＋ and the production of by-product, the desulphurization efficiency reduces unceasingly. Therefore, we add the Dian Yuan Bacteria 1 （DYB1）fungus, which take Fe^2＋ as the energy and can transformed Fe^2＋ into Fe^3＋ continuously in its multiplicative process, into the the desulphurization absorption solution to maintain the Fe^3＋ density, thus obtains the high desulphurization efficiency. The domestication of DYB1 as well as the adding of micro nutrients the key of DYB1 to play a full role.
