本文阐述了沉淀池表面负荷率与截留沉速的概念,认为平流沉淀池与斜管沉淀池截留沉速不相同。分析目前我国平流沉淀池具有挖潜增产的能力。导出斜管沉淀池的表面负荷率与截留沉速之间的计算式,提出斜管沉淀池的截留沉速为0.13~(mm)/s～0.23~(mm)/s。
This article expounds the concept of the surface loading rate of the sedimentation tank and the rate of interception and sedimentation. It is considered that the interception and settling velocity of the advection sedimentation tank and the inclined tube sedimentation tank are not the same. Analysis of current China’s advection sedimentation pool has the ability to tap potential increase production. The calculation formula between the surface loading rate and the interception and sedimentation rate of the inclined tube sedimentation basin was derived, and the interception and sedimentation rate of the inclined tube sedimentation tank was proposed to be 0.13 mm/s to 0.23 mm/s.
