This invention is a technique used in the water treatment field, such as a sewage treatment plant or a water purification plant. More specifically, the conventional technique of FIGS. 3 and 4 rotates a scum scaffolder which is caused by floating in the sedimentation process of sewage wastewater in the sedimentation basin structure. It is a technology that removes scum from sedimentation basin through scum discharge pipe connected to the outside by collecting them into the scum collection box.

However, the scum removal technology of the scum scraper that removes scum generated by sedimentation during sedimentation of sewage wastewater, which is a conventional technique, consists of a scum collecting box that is responsible for only a part of the radius of the sedimentation basin. The scum of the scum could not be completely removed and the scum that could not be removed is moved to the circumferential direction by the centrifugal force caused by the rotational force of the scum scraper, and then the scum is introduced into the scum collection box several times. Since the removal time of the scum has to be uncomfortable because it has to be removed, the scum generated as the scum is removed is settled again after a certain period of time has been inconvenient to deteriorate the water quality of the treated water. In addition, since new scum is caused to rise in the meantime, scum is always accumulated on the surface of the sedimentation basin, which has an inconvenience to impair the environment of the sedimentation basin.

The object of the present invention is to solve the conventional problems as described above, instead of the rectangular scum collecting box, which was responsible for only a part of the effective radius of the conventional circular settler, by improving the rectangular scum collecting box of the same length as the effective radius of the sedimentation basin. When the scum scraper rotates, the scum of radial water generated in the circular settler is collected and flowed into the scum collection box with only one rotation to improve the scum removal efficiency by reducing the scum removal time,

By shortening the removal time, the inconvenience of deteriorating the water quality of the treated water by settling again after a certain time after the scum is injured,

The rapid removal of scum has made it possible to improve the environment of the settling basin.

As a means for achieving the above object, the constitution of the present invention is a sedimentation basin structure (1) for the retention and sedimentation of sewage wastewater, a treated water discharge fit (2) for discharging the treated water to the outside, and treated water. Treatment water discharge channel (3) to be sent to the treatment water discharge pit, scum scraper driven motor (4) for rotating the scrubber, and central circular baffles (5) to allow the incoming wastewater to settle without causing vortices A scum scraper (6) to remove the scum injured in the sedimentation basin, a rubber plate (7) which directly plays a role in removing the scum while rotating the surface of the sedimentation basin integrally with the scum scraper, to collect scum which is the core of the design Rectangular scum collecting box (8) of the same length as the effective radius of the circular settler, flexible hose (9) to secure the fluidity of the scum collecting box and scum discharge pipe, and the scum collecting box The scum discharge pipe (10) for discharging the collected scum to the outside, sediment discharge pipe (11) for discharging the sediment deposited in the sedimentation basin, sewage waste water inlet pipe (12), 13: scum collection box into which wastewater flows in It is composed of a scum collecting box height adjusting bolt 13 and the like for fixing and adjusting the height according to the water level.

The structure of this invention is that the scum collection box is a rectangular rectangular box whose length is equal to the effective radius of the circular settler, so that the scum of the entire settling radius of the settling basin can be introduced into the scum collection box with only one rotation when the scum removing scraper is rotated. The structure has a gradient in the circumferential direction of the discharge surface so that the scum can be discharged smoothly into the scum discharge pipe, and the height can be adjusted according to the water level by the height adjusting bolt of the scum collection box. The cross section of the box can be rectangular or round or any other shape. Since the material is placed in water and comes into contact with the highly corrosive scum, it is composed of stainless steel-based corrosion-resistant metals or materials with corrosion resistance and strength such as F.R.P and P.E.

Since the scum discharge pipe is located in the water to discharge scum from the scum collection box to the outside, it is composed of stainless steel-based metal or material with corrosion resistance and strength such as F.R.P, P.E.

The height adjusting bolt is installed in the water so that the scum collection box can be adjusted according to the level of the sedimentation basin.

In addition, the connection of the scum collection box, which is a fluid chain, and the scum discharge pipe, which is fixed, is connected as a hose made of a material having strong corrosion resistance and flexibility (flexible), such as rubber series or PVC, to give fluidity between the scum collection box and the scum discharge pipe. Use it.
