| 摘 要： | 为深入了解膜生物反应器（MBR）中微生物代谢产物（SMP）的生成降解以及利用情况，研究了以NH4Cl为惟一能源物质的硝化MBR反应器中SMP浓度以及分子量（MW）变化情况，并运用活性污泥模型3（ASM3）准确地计算出微生物利用底物相关的溶解性产物（UAP）和微生物死亡相关的溶解性产物（BAP）的量分别是多少，最终证明硝化系统中产生的SMP可作为能源物质被异养菌进一步利用，而且相较于BAP而言UAP更易于被生物降解，得出结论BAP是SMP中的主要污染成分。

| Abstract: | To better understand the generation, degration and the utilization of soluble microbial products （SMP） in a membrane bioreactor （MBR）,the concentration and molecular weight （MW） changes of SMP in a MBR system which was only fed with NH4Cl as energy source were observed,the quality of utilization-associated products （UAP） and biomass- associated products （BAP） were accurately calculated by using activated sludge model 3 （ASM3）. The results demonstrated that the SMP generated in a nitrification system could be used as substrate for heterotrophic growth, and UAP was more readily biodegradable than BAP, therefore, BAP was the main pollution comoonents of SMP |
