The short - term temperature effects on the activity of nitrifying biofilm acclimated to very cold temperature about 0 . 5 and to moderate temperature were also investigated . the results indicated the former activity was seriously affected by the increase of temperature , but the latter activity was not thermo - labile 短期温度变化对硝化生物膜活性的影响研究表明,温度升高对长期适应于低温0 . 5的硝化生物膜活性影响很大,但对于适应于常温15的硝化生物膜并没有表现出热不稳定性效应。
