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 短期溫度變化對硝化生物膜活性的影響研究表明,溫度升高對長期適應于低溫0 . 5的硝化生物膜活性影響很大,但對于適應于常溫15的硝化生物膜并沒有表現出熱不穩定性效應。
