一株好氧反硝化-异养硝化菌的筛选及脱氮特性研究
Screening and Denitrification Characteristics of an Aerobic Denitrifying-Heterotrophic Nitrification Bacterium
摘要
Abstract
Aiming at the fact that the degradation of NO3-N and NO2-N in leachate is difficult, an aerobic denitrifying bacterium HN, preliminary identified asPseudomonas, was isolated from an aerobic biological reactor landfill. Based on its degradation capacities to different nitrogen sources, we studied the denitrification characteristics of HN and optimized the conditions for denitrification. The results showed that under aerobic conditions and potassium nitrate as sole nitrogen source, the removal efficiency of nitrogen in nitrate was up to 95.44% at 96 h;when using ammonium sulfate as sole nitrogen source, HN could remove 85.14% nitrogen in ammonia at 60 h;when the carbon source was ethanol, C/N was 7∶1, initial pH was 7.5, the temperature was 35℃ and inoculation amount was 10%, HN had the highest removal efficiency.关键词
