[0002] Sedimentation tanks are important facilities in sewage treatment, mainly used to remove suspended matter and sediment in water. Their basic principle is to use gravity to make suspended particles settle in still water to achieve the effect of solid-liquid separation. Sedimentation tanks play an important role in urban sewage treatment, industrial wastewater treatment and water resource reuse, and help improve water quality and the efficiency of subsequent treatment. The sludge discharge structure is one of the indispensable and important components of the sedimentation tank, which is used to discharge the sludge in the sedimentation tank.

[0029] Preferably, a water inlet pipe 201 is provided on one side of the buffer tank 20, and a plurality of vertically distributed deceleration baffles 202 are fixedly provided inside the buffer tank 20. Specifically, the deceleration baffles 202 can buffer the sewage entering the buffer tank 20 to avoid excessive water flow affecting the sedimentation of impurities.

[0034] Working principle: External sewage is introduced into the buffer tank 20 through the water inlet pipe 201, and then flows into the sedimentation tank 10. After the sewage stands in the sedimentation tank 10 for a period of time, the sludge in the sewage will settle to the bottom of the sedimentation tank 10. When the sludge needs to be discharged, the mud discharge port of the tee pipe 301 is opened, and then the motor a303 is started.

It should be noted here that when the sewage flows through the deceleration baffle 202, the fan-shaped staggered deceleration baffle 202 can effectively slow down the flow rate of the sewage and spread it in a fan shape into the sedimentation tank 10. When the sewage flows through the spoiler 102, the curling structure on both sides thereof can slow down the water flow and form a vortex, avoiding water surface agitation, and can effectively promote sludge sedimentation. The sedimentation chute 105 can guide the sludge into the mud discharge trough 106 in the middle.
