摘要
在进水口加设调流板、在溢流堰上沿水流方向设置溢流槽,从两个方面对传统平流式沉淀池进行了改进,设计出一种新型平流式沉淀池。通过试验研究分析了调流板和溢流槽对泥沙沉淀效果的影响,得出新型平流式沉淀池可以大大提高泥沙的沉淀效率,出池水流平均含沙量最大降幅可达94.8%,特别是对细颗粒泥沙的沉淀效果尤为明显。
Traditional rectangular settling tanks has been improved in two aspects by putting an adjusting flow board in the entrance of water and a spillway trough on spillway crest along the flow direction.Thus a new-type rectangular settling tank has been designed.The influence of adjusting flow board and spillway trough on sediment deposition has been analyzed by the experimental study.The results show that the new-type rectangular settling tank can improve the deposition efficiency of sediment greatly,and the biggest fall range of spillway crest,as sediment concentration is about 94.8 percent.It has a very nice effect on the deposition of fine sediment specifically.
