The present invention relates to a chain flylight type sludge collector installed at a square sedimentation basin in a sewage treatment plant.

The three functions of the sedimentation basin are the first to sediment the sediment to produce supernatant water, the second to remove the precipitated sludge, and the third to quickly remove the scum (floating residue) from the water surface.

The chain fright type sludge collector should have the ability to remove the sludge from the above three important functions and to quickly and completely remove the scum that floats on the surface, and to keep the sludge collector properly moving to prevent resuspension of the sludge. Should not interfere with the sedimentation basin's ability to settle the sediment.

The chain fright type sludge collector used in the four-side sedimentation basin of the conventional sewage treatment plant has the functions of removing the sedimented sludge and preventing the precipitated sludge from resurfacing among the important functions described above. There was a problem that could not be removed quickly and completely.

The bottom and wall surfaces of the quadrilateral sediments meet at right angles.For the safety of reinforced concrete structures, the areas where the floor and wall surfaces meet are sludge because they make a hunch with a 45 ° ramp width and height of 300 to 600 mm on each side. The length of the backlight of the collector is shorter than the width of the settling basin on the sides.

However, the chain fright type sludge collector removes the sludge deposited on the sediment bottom as the flight moves from the bottom of the sedimentation basin to the sludge hopper section. The scum is removed by pushing the scum to the flylight and moving the scum to the place where the scum eliminator is installed near the rear middle part of the sedimentation basin.

However, as described above, the length of the backlight is shorter than the width of the settling width by twice the width of the haunt (the hunt is on both sides) so that when the backlight is pushed backwards, the scum on the surface is not pushed backwards with the backlight. Although the scum from the surface of the water almost falls into the space between the sedimentation basin and the sprite, even if the falllight falls into the space between the light and the sediment wall and continues to move behind the sedimentation basin, the scum is not properly removed.

When scum occurs, the surface of the scum is in the form of a thin film to a thick film. The scum's film has stronger surface tension or resistance than water, and as the flight passes, it breaks the scum layer on both sides of the sedimentation basin. This fallout phenomenon occurs.

For this reason, the backlight is constantly moving backwards and tries to move the scum but the scum on the surface is not removed properly.

If scum on the surface is not properly removed, first, it is visually unpleasant, and if the water temperature is high, such as summer season, it decays and generates odor. Causes problems that worsen the water quality.

The technical problem to be achieved by the present invention is to provide a chain flylight type sludge collector that can completely and quickly remove the sludge precipitated in the quadrilateral sedimentation basin and scum floated on the water surface.

The present invention to achieve the above technical problem,
