摘要：

海水退潮过程中反应沉淀池沉淀区出现翻池，絮凝体大量上浮严重影响出水质量。通过对海水潮汐过程中 海水变化的分析，找出导致此现象发生的根本原因是海水密度和浊度变化使池内水流产生异重流。作者结合沉淀池结 构对异重流流态及其对沉降效果的影响进行了分析，并在此基础上提出了有效的应对方案。

Abstract:

During the course of seawater falling tide， a mass of flocculated granules floated upward to upside of sea water sedimentation tanks， which influences the effluent water seriously. By analyzing the change of sea water during tide， it is found that the basic causes are that the changes of density and turbidity of sea water result in the density current in sedimentation tanks. The density current flocculates the granules floated upward. Combined with the structure of sedimentation tanks， the cause that flocculate granule floated upward is analyzed， and the countermeasures are put forward.

Key words: sea water, sedimentation tanks, tide, density current
