Abstract: In order to improve the operational efficiency of the horizontal sedimentation tank,the application research on a new type of high-efficiency sedimentation pipe was conducted based on the shallow sedimentation theory using the design concept of water channel and sludge channel. The results show that it can improve the sedimentation effect and can be applied to improve the performance of horizontal sedimentation tanks in water treatment and sewage treatment and other fields,with strong practical application value.

Key words: horizontal sedimentation tank, sedimentation pipe, shallow sedimentation theory, turbidity
