摘要

采用中试规模的平行试验，研究了好氧式MBR和序批式MBR两种工艺处理生活污水的差异。结果表明两种工艺对有机物及氨氮的去除效果相当，由于序批式MBR提供了缺氧环境，其对总氮的去除能力优于好氧式MBR。但高溶解氧（DO）、低C/N以及缺乏机械搅拌装置限制了TN去除率的进一步提高。好氧式MBR的膜污染速率较序批式MBR严重，在截留有机物质量相等的情况下，二者的过膜阻力增长率分别为0.065 kPa·g-1·m2和0.037 kPa·g-1·m2。

Abstract

Two pilot-scale membrane bioreactors with different running processes were studied in treating domestic wastewater under the same conditions.The results showed that both systems had good ability for CODCr and ammonia nitrogen removal.Membrane sequencing batch reactor (MSBR) showed higher removal efficiency than aerobic membrane bioreactor (AMBR) for total nitrogen.But the high dissolved oxygen (DO)

low C/N and lack of mechanical agitation of MSBR limited further increase of the TN removal efficiency.The membrane fouling of AMBR was more serious than that of MSBR.The increase rates of TMP versus CODCr rejected by unit membrane area were 0.065 kPa·g-1·m2 and 0.037 kPa·g-1·m2 respectively for MSBR and AMBR.Detailed analysis was made to explain this phenomenon.
