The plane of the pool body is rectangular, the inlet and the outlet are respectively arranged at two ends of the pool, the inlet is generally submerged into the water inlet, water flows into the pool body from the water inlet channel through the water inlet holes which are uniformly distributed, and the baffle is arranged behind the water inlet holes, so that the water flow is uniformly distributed on the cross section of the whole pool width; the outlet is provided with an overflow weir to ensure that settled clarified water can flow into the water outlet channel uniformly along the width of the pool. A scum groove and a baffle are arranged in front of the weir to intercept scum on the water surface. The water flow part is the main body of the pool, the width and the depth of the pool ensure that the water flow is distributed uniformly along the water passing section of the pool and slowly and stably flows through the pool according to the designed flow rate. The sludge hopper is used for accumulating precipitated sludge and is arranged below the tank bottom at the front part of the tank, and the sludge discharge pipe is arranged at the bottom of the hopper for discharging sludge regularly. Water distribution of water inlet and water outlet is not easy to be uniform. When the multi-bucket mud discharging is carried out, each bucket needs to be provided with a mud discharging pipe (valve), the manual operation is carried out, the work is complicated, and the bucket is easy to rust when mechanical mud scraping is adopted.

(II) a vertical sedimentation tank, the working principle of which is shown in (b) of figure 1, and the sedimentation tank is used for vertically flowing waste water in the tank. The plane figure of the pool body is circular or square, water enters the pool from top to bottom through a water inlet pipe arranged at the center of the pool, an umbrella-shaped baffle is arranged below the pipe to ensure that wastewater slowly rises along the whole water passing section after being uniformly distributed in the pool, suspended matters settle into a conical sludge settling hopper at the bottom of the pool, and clarified water flows out from the periphery of the pool along a peripheral overflow weir. A baffle plate and a scum groove are arranged in front of the weir to intercept scum and ensure the quality of effluent. One side of the pool is provided with a mud pipe close to the pool wall, and mud is discharged periodically by hydrostatic pressure. The depth of the pool is large, the construction is difficult and the cost is high.

And the working principle of the radial flow sedimentation tank is shown in (c) of figure 1. The plane of the tank body is multi-round and also square. Wastewater enters the pool from a water inlet pipe at the center of the pool and slowly flows to the periphery of the pool along the radius direction. The suspended matters are settled in the flow and enter a sludge hopper along the gradient of the bottom of the tank, and the clarified water overflows from the periphery of the tank and flows out of a water channel. The radial sedimentation tank mostly adopts a rotary mud scraper to collect sludge, and a scraper plate of the mud scraper scrapes the sludge sinking to the bottom of the tank to a sludge hopper at the center of the tank and then discharges the sludge by gravity or a sludge pump. The bottom of the radial flow sedimentation tank has a gentle slope for the sludge discharge requirement of the sludge scraper. The mechanical mud discharging equipment is complex and has high requirements on construction quality.
