| 1 | 自养型生物过滤器硝化氧化一氧化氮显示文摘采用一种新的工程材料多孔碳作为填料 ,在 3个5 0 8mm填充着不同孔径多孔碳和驯化培养好的自养型亚硝酸盐硝化菌的生物过滤器中 ,进行了净化气体中NO的探索性研究 .实验采用亚硝酸盐为唯一氮源 ,在多孔碳的表面培养生物膜 ,采用超声波气溶胶发生器来维持过滤器内的湿度并保持多孔碳表面液膜的厚度较小 .液相硝化试验用来比较 3种不同孔径的多孔碳之间硝化性能的潜力和差异 .结果表明 ,在亚氮 (NO- 2 N)进口负荷约2 0 0~ 80 0g/(L·min)的范围内 ,2 4孔 /cm(PoresPerCentimeter,PPC)多孔碳过滤器的硝化速率最大 ,达到 94%~98%;8PPC和 1 8PPC多孔碳过滤器的硝化速率分别达到 1 5 %~ 2 1 %和 3 0 %~ 40 %.气相试验表明 ,在NO空床停留时间 3 5min、进口浓度 66 97~ 2 67 86mg/m3的范围内 ,2 4PPC多孔碳过滤器对NO的去除效率为 41 %~5 2 %左右 。 | 陈建孟 Lance Hershman 陈浚 Daniel P.Y.Chang | 2003 | 环境科学2003,24,2: | 20 |
| 2 | Autotrophic Biofilters for Oxidation of Nitric Oxide显示文摘Carbon foam—a kind of new engineering material as packing material was adopted in three biofilters with different pore dimensions and adapted autotrophic nitrite nitrobacteria to investigate the purification of nitric oxide (NO) in a gas stream. The biofilm was developed on the surface of carbon foams using nitrite as its only nitric source. The moisture in the filter was maintained by ultrasonic aerosol equipment which can minimize the thickness of the liquid film. The liquid phase nitrification test was conducted to determine the variability and the potential of performance among the three carbon foam biofilters. The investigation showed that during the NO2^-—N inlet concentration of 200 g·L^-1·min^-1 to 800 g·L^-1·min^-1, the 24PPC (pores per centimeter) carbon foam biofilter had the greatest potential, achieving the NO2^-—N removal efficiency of 94% to 98%. The 8PPC and 18PPC carbon foam biofilters achieved the NO2^-—N removal efficiency of 15% to 21% and of 30% to 40%, respectively. The potential for this system to remove NO from a gas stream was shown on the basis of a steady removal efficiency of 41% to 50% which was attained for the 24PPC carbon foam biofilter at specified NO inlet concentration of 66.97 mg·m^-3 to 267.86mg·m^-3 and an empty-bed residence time of 3.5 min. | 陈建孟 陈浚 Lance Hershman 王家德 Daniel P.Y.Chang | 2004 | Chinese Journal of Chemical Engineering2004,12,1: | 4 |
