摘　　要：以实验室保藏菌种为基础,构建了偏二甲肼高效复合降解菌群FYD,以期应用于偏二甲肼泄露到水体中时的应急处理。通过菌群降解偏二甲肼影响因素实验确定了该菌群降解偏二甲肼的最优条件:温度为35℃,pH值7.2,接种量2%,偏二甲肼初始浓度50 mg.L-1,此条件下偏二甲肼的72 h降解率最高,为99.10%,出水偏二甲肼浓度小于0.5 mg.L-1,各项指标均达到GB14374-1993要求的排放标准。On the basis of the unsymmetric dimethydrazine （UDMH）-degrading bacteria preserved in laboratory, the compound flora FYD was build with a view to use in the emergency situations when UDMH leaked into water. The optimal conditions for degradation of UDMH determined by effect factors experiments are as following： temperature 35 ℃, the medium pH 7. 2, inoculation 2%, the initial U DMH concentration 50 mg · L-1. Under this condition, the highest U DMH degradation rate, is 99.10%, and UDMH residual concentration is less than 0.5 mg · L-1 in 72 h, and all the indicators of water meet the requirements of G B1473 - 93 emission standards.
