生物膜填料塔净化模拟烟气和电厂烟气中SO2和NOx的对比实验
Comparative experiment on removal of SO2 and NOx from simulated gas streams and flue gas by biological film packed tower
摘要
Abstract
The removal of sulfur dioxide (SOL) and nitrogen oxides (NO) from simulated gas streams and flue gas was studied. Removal efficiency of SO2 and NOx in different gas was compared and analyzed under the same conditions. It is indicated that, with empty bed residence time (EBRT) of 60 s, cycling fluid of 8 - 10 L/ h, cycling fluid temperature of 24 - 35℃ , cycling fluid' s pH value of desulfurizing tower of 0.8 - 1.5 and deni- trification tower pH of 7.5 - 8.0, the biological film packed tower showed a high removal efficiency of simulated gas streams and flue gas purification of SO/. Average rate of the total nitrogen removal efficiency of simulated gas streams was 80% , and removal rate of flue gas was 35%. By analysis, the main reasons of the discrepancy of the nitrogen removal efficiency were the impurities and the oxygen concentration in flue gas. At the same time, different micro populations which were acclimated under different growth conditions can be another reason.关键词
