| 摘 要： | 膜生物反应器中ＭＬＶＳＳ为４０００－５００0mg／Ｌ时，ＣＯＤ的去除率可达９８％左右，ＮＨ３－N的去除率可达９９％左右，但随ＳＲＴ的继续延长，污泥浓度的增加，使得内源呼吸加剧和大量微生物死亡，导到处 海ＣＯＤ上升，ＳＭＰnd含量增加，出水ＣＯＤ存在波动性，但ＣＯＤ的去除率仍在９４％左右，同时ＳＭＰnd的增加会抑制硝化作用，ＮＨ３－Ｎ的去除率会略有下降，可持续在９２％左右，低温和有机负荷的冲击对ＣＯＤ的去除影响不是很大，但对ＮＨ３－Ｎ的去除影响很大。

| Abstract: | Concludes from the results of investigation that the removal rates of COD and NH3-N are 98% and 99% respectively, when the concentration of MLVSS is 4000～5000mg/L, however, as the SRT and MLVSS continue to increase, the COD concentration of filtrate through filter paper and Soluble Metabolic Products (SMP) increase due to intensification of internal respiration and death of microorganisms, but the removal rate of COD is still about 94%, although it fluctuates, and the increase of SMP inhibites the nitrification of NH3-N, and the removal rate of NH3-N drops to about 92%; Low temperature and high organic loading have little influence on the COD removal rate, but have great impact on NH3-N removal. |
