| 摘 要： | 采用生物膜填料塔实验装置,从添加pH缓冲剂、CO2气体、有机酸、金属离子催化剂以及好氧/厌氧、中性/酸性操作条件等方面,对提高生物法净化低浓度NOx废气(以NO为主要成分)性能进行了实验探索.结果表明,以NaHCO3作为缓冲剂、添加少量冰醋酸以及在好氧及中性条件下操作,能够显著提高生物膜填料塔对废气中NO的净化性能.对于在好氧及酸性条件下,添加少量金属离子催化剂同样可以明显提高生物膜填料塔对废气中NO的净化性能. |

| Abstract: | By means of the test systems of biofilm-packing tower,a test study on enhancing capability for biopurifying NOx(NO as a basis) waste gas was performanced,in which the effects of adding pH buffer,CO2 gas,organic acid,metal ions catalyst and operating the test tower under the aerobic/anaerobic condition,the neutral/acidic condition on the purification capability of NO waste gas were studied.The results showed that by adding NaHCO3 as a pH buffer,a little glacial acetic acid and operating the tower under the aerobic/neutral condition,the capability of the biofilm-packing tower for biopurifying NOcould be enhanced markedly.Under the aerobic/acidic condition,by adding a little metal ions catalyst,the capability for biopurifying NO could be improved obviously as well. |
