摘　　要：文章通过定时测定培养液中NO3--N、NO2--N和细菌浓度,分别研究了菌株DB1在水和含水层中反硝化的能力;结果表明,该菌株在水中可使NO3--N的去除率达到96.16%,在模拟含水层中能够彻底去除NO3--N,去除率达到100%;NO3--N的去除和NO2--N的积累主要发生在细菌对数生长期,NO2--N的去除主要在稳定期和衰亡期。The denitrification activity of the strain was investigated through determining NO3^--N, NO2^--N and concentration of the strain in medium. Results show that the removal efficiency of NO3^--N reached 96.16% in water, and complete denitrification was achieved in simulated aquifer with the removal efficiency of 100%; the removal of NO3 -N and accumulation of NO2-N mainly happened in the exponential phase. The removal of NO2 -N mainly happened in the stable and inclining periods.
