| 摘 要： | 研究基于中试规模的浸没式膜生物反应器长期运行的基础上,通过改变操作条件和工艺参数系统考察污泥组分对膜污染的影响。试验结果表明,泥龄10 d时，混合液悬浮固体、胶体物质和溶解性物质对膜污染阻力的贡献分别为24.1%、36.1%和39.8%；泥龄20 d时, 混合液悬浮固体、胶体物质和溶解性物质对膜污染阻力的贡献分别为43.9%、32%和24.1%；泥龄40 d时, 混合液悬浮固体、胶体物质和溶解性物质对膜污染阻力的贡献分别为50.6%、27.3%和22.1%。随着泥龄的增加,胶体物质和溶解性物质所形成的阻力之和在总阻力中所占的比例逐渐下降,但仍为膜污染的重要因素。

| Abstract: | The impacts of sludge components on membrane fouling were studied by changing the operational conditions and parameters of a pilot-scale submerged membrane-bioreactor,which had been successfully operated for more than one year.The results showed that the contributions of suspended solid,colloids and solutes to the membrane fouling were 24.1%,36.1%,39.8% at SRT of 10 days,and 43.9%,32%,24.1% at SRT of 20 days,50.6%,27.3% and 22.1% at SRT of 40 days,respectively.It was also found that the proportion of foulin... |
