Description

Scum Skimmer Having Scum Crusher Using a Shredding Apparatus [

The present invention relates to a scum skimmer using a crusher, and more particularly, to a scum skimmer using a crusher, and more particularly, to a scum skimmer which functions to filter sludge scum generated on a water surface before discharging treated water in a sewage treatment facility, The present invention relates to a scum skimmer using a scraping device including a scum crusher for crushing, coagulating, sedimenting, and removing the bottom of the sludge.

The sedimentation tank provided in the sewage end treatment plant is required to purify the treated water through sedimentation of the sludge and collects and removes the sedimented sludge and to remove the scum which is suspended in the treated water surface in the sedimentation tank .

In addition, sedimentation tank is a tank for separating solids and liquid by sedimenting suspended solids (solid particles dispersed in water) contained in raw water using a specific gravity difference.

At this time, the suspended material can be explained by the sludge or sludge contained in the raw water.

The sedimentation tank has a direct effect on the water quality of the effluent (purified water) as the final process of the effluent and wastewater treatment plant and the water treatment plant, and efficient design is required because it can effectively remove the suspended matter component of the raw water.

Such a sedimentation tank has been developed in various forms such as a rectangular sedimentation tank and a circular sedimentation tank.

The sludge collector is used to collect and remove the settled sludge in the settling basin.

For example, a chain flight type sludge collector is applied to a rectangular sedimentation tank of a sewage end treatment plant and is used for collection of sludge.

The sludge collector includes a pair of chains arranged along the longitudinal direction of the rectangular sedimentation basin, and a plurality of flights arranged across the pair of chains are arranged along the longitudinal direction of the chain.

During chain driving, the plurality of flights have an upper travel path at the upper portion of the chain and a lower travel path at the lower portion of the chain.

That is, each of the plurality of flights travels along the upper travel path from one side view point of the chain to the other end point position of the chain, and then moves backward along the lower travel path to the one viewpoint position of the chain by changing the direction at the other end point position of the chain , And this movement is repeated continuously.

In addition, when each of the plurality of flights moves along the lower movement path, the sludge settled in the lower part of the settler is moved to the sludge removing position to perform the collecting function of the sludge.

However, as described above, the sediment is precipitated by the sedimentation tank to separate the solid and the liquid. At this time, some suspended substances do not sink to the bottom of the sedimentation tank, but float in the water and float up, There has been a problem that it has to be processed.

Generally, the conventional scum removing device is installed in the rectangular settling tank and the circular settling tank described above. In the case of the rectangular settling tank, a sprocket rotated by a motor provided in the settling tank, a chain wound around the sprocket, In the case of the circular sedimentation tank, it is composed of a rotary motor installed on the upper part of the sedimentation tank, and a scum scraper which rotates by the rotary motor and collects the scum floating on the upper part of the raw water.

Conventionally, a system integrating a scum skimmer and a sludge collector has been developed.

Such a conventional scum skimmer includes a spiral shape which rotates in a clockwise direction while being horizontally installed in a water channel of a settling tank adjacent to a water surface.

Such a spiral-shaped scum skimmer includes a rotating shaft and spiral wings, which are intended to wipe scum on the surface of the water.

However, the scum skimmer according to the prior art generates resistance against the treated water in the sedimentation tank and the scum flow floating on the treated water, and the removal efficiency of the scum is greatly reduced.

This causes secondary water pollution by discharging undisclosed water to the river as it is.

In addition, there have been various attempts to develop scum skimmer, but it was difficult to obtain the efficiency of removing scum more than intended.

The above-mentioned scum skimmer has a problem that the odor due to the residual scum in the settling tank is generated and the treated water discharged through the scum box has to be reprocessed.

In order to agglomerate the scum, the scum must be finely crushed and the particles must be small so that the agglomerate is flocculated and coagulated like a flocculant.
