Abstract

Four strains of dominant bacteria of A、B、C and D for propylene oxide wastewater degradation are gotten by screening and acclimation.Study on the strain A which has the best degradation efficiency is conducted.The results show that its optimum conditions is temperature of 30℃,pH of 5,wastewater concentration of 20% and react time of 9 h,at which COD removal rate achieves about 63.24%.
