摘　　要：采用富集培养、以中药废水为单一碳源定向梯度驯化的方法,从处理中药废水的一体化装置分离,筛选对高浓度有机物有高效降解能力的菌株,从水解酸化段筛选到5株功能菌、接触氧化段筛选到4株功能菌,在进水COD浓度为6500 mg/L条件下,该9株微生物对COD的去除率均在85%以上,其中菌株sj2、sj5、jc1降解效果尤为突出,COD降解率分别约为97.8%、96.1%和97.3%。对9株微生物进行形态观察和生理生化实验,初步判定8株为细菌、1株为霉菌。In this study,bacterial strains capable of degrading high-concentration organics were screened from traditional Chinese medicine(TCM)wastewater that was treated in an integrated device.Methods of enrichment culture and directional gradient acclimation were used with the TCM wastewater being the sole carbon source.5 and 4 functional strains were obtained in the stages of hydrolytic acidification and contact oxidation,respectively.Under the condition of influent COD concentration being 6500 mg/L,these 9 strains of microorganism can remove more than 85%of the COD.In particular,the removal rates of strains sj2,sj5 and jc1 are fairly high,being around 97.8%,96.1%and 97.3%,respectively.Physiological and biochemical experiments regarding morphological observation were also conducted for the 9 strains of microorganism.It was preliminarily determined that 8 strains were bacteria and 1 strain was mold.
