摘要
以氧化亚铁硫杆菌固定化生物膜和铁离子复合体系为基础构建了燃煤烟气的微生物循环脱硫工艺。以多面空心球为载体实现了氧化亚铁硫杆菌的固定化,固定化生物膜具有孔隙率高、比表面积大的特点,有利于细菌的吸附及SO2的脱除。脱硫试验表明,SO2入口浓度1 000 mg/m3以下,烟气流量1.0 m3/h,循环液流量40～60L/h为适宜工艺条件。
The flue gas desulphurization by microorganism technology was established based on Acidithiobacillus ferrooxidans biofilm and multiplex iron system.Immobilizing biofilm has formed on the surface of polyhedron empty ball with the characteristics of high porosity and big specific surface area.This particular biofilm is favorable for Acidithiobacillus ferrooxidans adsorption and SO2 reduction.Desulphurization test results showed that the conditions of inlet concentration of SO2 under 1 000 mg/m3,flue input of 1.0 m3/h, and circulating fluid flow of 40 - 50 L/h were feasible.
