摘　　要：采用模拟城市污水处理厂A/O工艺的实验装置处理生活污水,以考察投加生物水处理剂LLMO对曝气池的污泥浓度、污泥沉降性能以及处理水水质(CODCr、TOC、T-N)的影响。通过15 d的观察,结果表明出水CODCr、、TOC、T-N都比较稳定,曝气池的悬浮物浓度(MLSS)、污泥容积指数(SVI)总体趋势亦比较稳定且略有下降。The experimental devices simulated the A/O method used by municipal wastewater treatment plant was utilized to treat living wastewater.By adding LLMO in aeration tank,the influence on MLSS,SVI and effluent quality was researched.The results reveal that CODCr,TOC,T-N of effluent were stable,and MLSS、SVI in aeration tank had a general stable trend and declined slightly.
