| 摘 要： | 在接种污泥、进水水质、反应器尺寸及水力停留时间相同的条件下，比较了膜生物反应器（MBR）和传统活性污泥工艺（CAS）在污泥驯化期的除污效果和污泥特性。结果表明，MBR对COD的去除效果优于CAS的，两工艺对氨氮的去除效果差异不大；MBR中的污泥絮体较CAS中的分散，原生动物和后生动物的种类也较少；MBR中的污泥浓度远高于CAS工艺的，其污泥的体积平均粒径小于CAS的；两反应器中的活性污泥均表现出了较好的沉降性能。

| Abstract: | The comparison of pollutant removal efficiencies and sludge performances between the membrane bioreactor(MBR) and the conventional activated sludge process(CAS) during the sludge acclimation period was carried out under the similar conditions of inoculation sludge,influent quality,reactor size and HRT.The results show that MBR has a higher COD removal efficiency than that of CAS,but both have similar removal efficiencies of ammonia nitrogen.The sludge floc in MBR is more dispersive than that in CAS,and the species of protozoan and metazoan are also less than that in CAS.MLSS in MBR is significantly higher than that in CAS,but the average particle size of sludge is smaller than that of CAS.Sedimentation performances of sludge in both reactors are favorable. |
