| 摘 要： | 对可溶性微生物产物(SMP)的产生和性质进行了概述，指出SMP是影响生化出水水质的重要因素；建立了完全混合反应器中SMP浓度的计算公式。基质降解量(△S)、污泥龄(@)、污泥产率因数(y)和衰减速率系数(b)是影响SMP浓度的4个重要因素，SMP浓度同污泥浓度、水力停留时间无关。分析表明，对应某污泥龄，反应器中SMP浓度可达到最低，控制污泥龄可以达到降低出水中SMP浓度的目的。

| Abstract: | The production and properties of soluble microbial products (SMP) are summarized.it is pointed that SMP is a main factor affecting biotreatment effluent quality.The calculation formula of SMP concentration in CSTR is established.Substrate degradation amount,sludge age,sludge yield and endogenous-decay coefficient b are four important factors affecting SMP concentration,which is independent of sludge concentration and HRT.The analysis proved that SMP concentration in bioreactor would be the lowest at a certain sludge age.A lower SMP concentration can be anticipated by controlling sludge age. |

| Keywords: | soluble microbial products biological treatment sludge age |
