Description

[Detailed Description of the Invention] The present invention relates to a sedimentation separator that can suitably treat various types of polluted water.

Conventional sedimentation separators are designed based on the quality of polluted water to be treated in advance. Therefore, if the quality of contaminated water fluctuates significantly from the water quality standard set at the time of design, or if a treatment amount far from the set value flows in, the desired sedimentation and separation treatment cannot be performed.

The inventor of the present invention has completed various studies to solve the drawbacks of these conventional sedimentation separators, and as a result has completed the present invention. That is, as shown in FIG. 1, the sedimentation separator according to the present invention has a polluted water introduction part of the sedimentation separator with a square-shaped multi-hole partition wall A, and a T-shaped slit separated by a certain distance from the square-shaped multi-hole partition wall A. A wall B is provided.

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a plan view showing an example of a sedimentation separation apparatus. The polluted water is allowed to flow into the introduction section 1 of the sedimentation separator. The inflowing polluted water is collected through the square-shaped multi-hole partition wall A.
Because of the presence of the turbidity, the polluted water is stirred with some degree of interference. Next, this square-shaped multi-hole partition wall A
The polluted water that has passed through is then influenced by the T-shaped slit wall B, and is subjected to even stronger interference.
And this square-shaped multi-hole partition wall A and T-shaped slit wall B
The polluted water is homogenized and the polluted particles in the polluted water are separated and settled in the interference bed between the polluted water and the polluted water.

As shown in FIGS. 4 and 5, the square-shaped multi-hole partition wall A has a structure in which squares are placed back to back, and a water outlet 1 is provided at a location corresponding to the bottom portion. In addition, as shown in Figure 6, there is a collar 2 at the water outlet 1.
It is also possible to have a

When the polluted water passes through this square-shaped multi-hole partition wall A, it is thoroughly mixed by the square-shaped inlet section 3 and flows through the outlet port 1.
pass through. The polluted water that has passed through the water outlet 1 then flows into the interference bed 4 as a diffusion flow. Here, the pollutant particles in the polluted water settle. Furthermore, as shown in FIG. 7, the polluted water passing through the T-shaped slit wall B further promotes the settling of the pollutant particles in the interference regions that occur before and after the slit wall B, thereby making it possible to separate the pollutant particles.

The polluted water that has passed through the T-shaped slit wall B flows toward the pit 5 into the sedimentation separator while being accompanied by sedimentation of pollutant particles. Furthermore, T-shaped slit wall B
If desired, a float fence as shown in FIG. 8 may be disposed in a connected manner in the downstream direction. Further, a turbulence plate C may be provided at the water inlet 1 of the sedimentation separator in order to generate turbulence in the flow of polluted water.

According to the present invention, it can be used not only for thickeners but also for sand settling basins, settling basins, etc.
