Description

Technical Field

[0002] Sedimentation tank is a kind of structure that uses sedimentation to remove suspended matter in water and is a device for purifying water. It uses the natural sedimentation of water or the effect of coagulation and sedimentation to remove suspended matter in water. Sedimentation tanks are divided into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. The sedimentation effect is determined by the flow rate of water in the sedimentation tank and the residence time of water in the tank. In order to improve the sedimentation effect and reduce the land area, honeycomb inclined tube countercurrent sedimentation tanks, accelerated clarification tanks, pulse clarification tanks, etc. are currently used. Sedimentation tanks are widely used in sewage treatment.
