Abstract:

Traditional sediment tank has been improved in three aspects by putting an adjusting flow wall in the entrance of water,a spillway through on spillway crest along the flow direction,redesigning the flush device and an auxiliary flush facility.Thus a new-type rectangular sediment tank has been designed.It can greatly improve the deposition efficiency of sediment tank,especially it has a very nice effect on the deposition of fine sediment.

Key words: rectangular sediment tank, adjusting flow wall, spillway through, flush device

摘要：

通过在沉砂池的进水处加调流墙、在溢流堰上沿水流方向设溢流槽、对排砂装置进行改进以及设置辅助冲砂设施三个方面对传统平流式沉砂池进行了改进,设计提出了一种新型平流式沉砂池,可以大大提高沉砂池的沉淀效率,特别是对细颗粒泥砂的沉淀具有很好的效果。
