摘要

本研究设计了水库前复合系统，探讨了非点源污染中悬浮粒子的去除效果。考察了操作参数(停留时间)对SS去除率的影响，分析了出水粒度分布。结果表明，该系统能高效去除SS。当停留时间为24h时，SS的去除率达到90%以上。粒度分布分析结果表明，泥沙区SS云的粒径> 30µm和<4µm被物理沉降去除。在深水区通过植物截留去除粒径3 ~ 9µm的SS云。

Research on composite of pre-reservoirs technology for the removal of SS in non-point sources pollution

In this study, the composite of pre-reservoirs system was designed and to explored the removal of suspended particles (SS) in the non-point sources pollution. The operating parameter (residence time) was investigated its effect on the SS removal, and the particle size distribution of effluent was analysis. The results showed that this system could remove the SS with high efficiency. When the residence time was 24hrs, SS could remove over 90%. From the Particle Size Distribution analysis, the results revealed that the particle size > 30µm and <4µm of SS cloud be removed in sediment area by physical sedimentation. And the particle size of 3∼9µm of SS cloud be removed in deep water area by plants interception.
