| 摘 要： | 采用微氧颗粒污泥膜生物反应器处理生活污水,进行同时去除有机物和氮的研究。结果表明,膜出水COD不受水力停留时间变化的影响一直稳定在较低值,为15~35mg/L,去除率在94%以上。氮通过发生同时硝化反硝化反应而去除。在水力停留时间为16h以上时, 系统总氮去除率为65% ~92%,平均去除率为77%。

| Abstract: | The performance of a microaerobic membrane bioreactor seeded with granular sludge was investigated for concurrent removal of organic substances and nitrogen from the synthetic domestic wastewaters. The membrane effluent COD concentration was always low: 10~35 mg/L. The total COD removal efficiency of more than 94% was achieved throughout the whole operation period. N was removed through the simultaneous nitrification and denitrification process. At the hydraulic retention time of more than 16 h, the TN removal reached 77% on average (65%~92%). |
