摘　　要：目的:复壮有效微生物(EM)并初步研究其降解偏二甲肼的效果。方法:以摇床培养法复壮EM,采用在自配含偏二甲肼污水中直接投加EM复壮液的方法,检测EM对偏二甲肼的降解。结果:以pH和OD值为观测指标,五种培养基均能复壮EM,复合培养基复壮的效果最好;在温度30℃、摇床转速为100 r/min时,其复壮的EM7 d内能将140 mg/L偏二甲肼降解至13 mg/L。结论:EM能有效降解偏二甲肼。Objective： To rejuvenate the effective microorganisms （EM） and then study its effect on degrading unsymmetrical dimethylhydrazine（UDMH）. Methods： EM was rejuvenated in the shake culture device, and then added in the sewage containing UDMH to detect the content of UDMH. Results ： EM can be rejuvenated in 5 culture media. Under the condition of 30 ℃, 100 r/min as shaking velocity,C（EM） =5%, the EM rejuvenated in the complex culture medium had the highest degrading rate. In this way, 140 mg/L of UDMH can be degraded to 13 mg/L in 7 days. Conclusion： UDMH can be degraded effectively by EM.
