| 摘 要： | 在人工湿地模型中,研究了人为增加湿地植物根际微生物对生活污水中COD的降解效果:将2株从湿地分离的根际微生物扩增培养(分别用于模型1与模型2),与一定比例的生活污水混合后注入到湿地模型中,在停留12,24,36,48 h时分别测定污水中COD的去除率.结果表明,加菌模型对COD的去除率显著高于空白模型(P<0.05),且随着时间的延长,二者的差异性越大,至48 h时,空白模型和2个加菌模型(模型1和模型2)对自然污水COD的去除率分别为50.6%,73.0%,75.3%,对灭菌污水COD的去除率分别为52.2%,76.3%,80.1%.说明向人工湿地中添加植物根际微生物将大大提高湿地对生活污水中COD的去除率,具有进一步开发的价值.

| Abstract: | The experiment studies the effects of artificial adding of rhizosphere microorganism on the degradation of COD in sanitary wastewater by wetland models.Two rhizosphere bacteria isolated from the constructed wetland are mixed with a certain proportion of waste water and injected into the wetland model.The degradation of COD is examined at 12 h,24 h,36 h,48 h respectively.The results indicates that the COD degradation ratio of the bacteria models is significantly higher than that of the controlled model(P<0.0... |
