Further, the present invention can be operated without deterioration of long- , And a slope plate settling facility in which corrosion can be completely prevented.

Conventionally, in a water treatment or wastewater treatment facility, a sedimentation paper having a structure in which a swash plate is installed in a sedimentation tank in a superimposed manner in order to reduce the area of a large sedimentation tank and thus the cost thereof has been developed and partially employed. However, frequent clogging Due to the performance degradation due to the closure and difficult maintenance, the performance is not fully achieved despite the theoretical advantages. As such a swash plate, a synthetic resin plate or a metal plate excellent in corrosion resistance and abrasion resistance is used.

Such inclined plate built-up papers can increase sedimentation efficiency by increasing sedimentation area as well as accelerating sedimentation of solid content together with upward flow of the fluid to be treated on the swash plate.

As an example of the above conventional technology, the invention of U.S. Patent No. 6,245,243 will be described briefly together with FIG. 1 to FIG. 2b.

FIG. 1 shows a partially oblique perspective view of a conventional swash plate settling apparatus, and FIG. 2A and FIG. 2B show enlarged cross-sectional views taken along line 2A-2A in FIG. 1 and line 2B-2B in FIG.

1, the sedimentation purification apparatus 25 is for removing substances such as the solid matter 26 from the raw water 27, and is provided with a vertical (vertical) flow path 29 for forming a sedimentation tank 29 having an open top 30 and a bottom portion 31, And an outer wall 28. When the raw water 27 containing the solid content 26 flows into the outlet 33 through the inlet 32 and flows into the sedimentation purification facility 25 at a very low flow rate in the substantially stationary flow channel 34 are formed. That is, the raw water 27 containing the solid component 26 flows upward in the flow channel 34 in the direction of the arrow 27A to remove the solid component 26 from the raw water 27, ).

The settling tank 29 may be formed by dividing a plurality of sections 37 by a vertical internal partition 38 and the channel 36 may be formed on both side portions 36A or one side 36A of each section 37. [ As shown in FIG.

1 to Fig. 2B, a fluid pipe serving as an even distribution of treated raw water is provided on the side of the water channel, and a liquid containing foreign matters is discharged from the vicinity of the bottom 31 of the settling tank 29 to the inside of the swash plate 44 The solids fall down toward the bottom while the solids flow downward to some extent as indicated by arrows 26 and 27 in FIG. Which is located at the upper end region 46Z of the flow path corresponding to the upper end 46P of the hollow support member 42 and which is arranged at regular intervals along the longitudinal axis 43, 51 to the inside of the pipe, thereafter flows along the water passage 36 and flows out to the outlet. The liquid surface height 48-1 of the process water on the flow path between the swash plates 44 is maintained slightly higher than the upper end 49 of the pipe 42 and the flow path between the adjacent swash plate side baffles 54, It is most preferable to be configured so as not to be in contact. The distance between the orifices 51 of the pipe 42 is determined according to the estimated flow rate of the incoming raw water. The height of the inclined plate side baffle 54 should be determined according to the level of the liquid level 48-1 and the inclined plate side baffle 54 is formed as a separation structure for removably installing the oil pipes 42 in the channel 36 .

However, in the above-described structure, the swash plate 44 is mainly made of stainless steel in order to prevent corrosion, but since it is difficult to prevent corrosion completely, clogging due to adhesion and accumulation of sludge occurs There is a problem that the precipitation efficiency is lowered, and furthermore, the inclined plate of the corroded stainless steel material must be repaired or replaced.

In addition, in the case of the stainless steel material, there is a problem that the structure such as a frame or the like must be firmly constructed because it is a heavy material, and furthermore, the entire structure becomes heavy.
