Be provided with at the axle center department of water injection district 11 and be columniform center tube 2, along a plurality of connecting rods 21 of center tube 2 circumference fixedly connected with on the lateral wall of center tube 2, the other end fixed connection of connecting rod 21 is on the inner wall of sedimentation tank body 1. The top of passing through the sedimentation tank body 1 is provided with a water inlet channel 3 with a U-shaped longitudinal section, and the water inlet channel 3 is communicated with the top of the central pipe 2. The both sides of inhalant canal 3 are vertical setting and highly are higher than the baffle 31 of center tube 2, can prevent through setting up baffle 31 that rivers from taking place to spatter outward when too big.

When the waste water that produces is selected to the iron needs to be handled, pour into the center tube 2 with waste water along inhalant canal 3 to throw into corresponding proportion's medicament in towards center tube 2, can react and form mud with the pollutant in the waste water when medicament and waste water are mixed each other. The sludge, once formed, will gradually settle downwardly due to gravity and eventually fall to the settling zone 12 for settling. Fixedly connected with mud pipe 4 on the lateral wall of settling zone 12 bottom, mud pipe 4 and the inside intercommunication each other of settling zone 12, the mud that carries out the sediment in settling zone 12 can be discharged along mud pipe 4.

Fixedly connected with longitudinal section is mounting panel 5 for the L shape on the inside wall at sedimentation tank body 1 top, and mounting panel 5 includes integrated into one piece's horizontal part 51 and vertical portion 52, and the upper boundary of vertical portion 52 is less than the upper boundary of sedimentation tank body 1, forms water catch bowl 53 between mounting panel 5 and the sedimentation tank body 1. A drain pipe 54 communicated with the water collecting tank 53 is fixedly connected to the outer side wall of the sedimentation tank body 1. When the sludge is settled downward, the clean water separated from the sludge spreads upward, the upwardly spread clean water enters the water collection tank 53 along the upper boundary of the vertical portion 52, and the clean water entering the water collection tank 53 is discharged along the water discharge pipe 54.

A serrated overflow weir 521 is provided at the upper edge of the vertical portion 52, and the water flow can be made to flow into the water collection tank 53 gently by providing the overflow weir 521, so that the impact force when the water flow flows out can be reduced; meanwhile, the water flow can be ensured to uniformly flow into the water collecting tank 53 along the circumferential direction of the sedimentation tank body 1.

At the top fixed connection of sedimentation tank body 1 there is the overline bridge 6 of level setting, can make things convenient for the staff to apply the medicament towards sedimentation tank body 1 inside through setting up overline bridge 6.
