Mixed liquor suspended solids increased with the increase of sludge retention times and volumetric loading rates.

污泥浓度随污泥龄的增加、水力停留时间的缩短、容积负荷的增大而增加；

youdao

The resistance caused by suspended solids of the mixed liquor occupied 70% of total membrane resistance, that by colloidal substance occupied 22% and that by soluble substance occupied fraction 8%.

结果表明，污泥混合液悬浮固体形成阻力占膜总阻力的70%，胶体物质形成阻力占22%，溶解性物质形成阻力占8%。
