Description

Scum removal device {Apparatus for removing scum}

The present invention relates to a scum removal device, and more particularly, a scum removal unit including a guide pipe, a scum pipe, a drain pipe, and a scum plate, and water containing the scum discharged through the drain pipe of the scum removal unit is received. By including an elevating and discharging unit that controls the water level of the surface of the flocculating pond and a discharge water spraying unit that sprays the discharged water from one side of the scum removal unit while discharging to the outside, the height of the scum removal can be easily adjusted to the surface of the flocculating area. At the same time, it is possible to remove the scum floating on the surface of the condensed area and smoothly discharge the scum together with the discharged water, and through this, it relates to a scum removal device that maximizes the discharge efficiency for scum.

Generally, sewage that is thrown away from homes or factories is sent to a sewage treatment plant and then treated.

This sewage treatment process includes a water purification process and a sludge treatment process. First, in the water purification process, the sewage is purified to the extent that the self-purification of the river can be triggered, and then discharged into public waters such as rivers. The sludge generated in the process is treated through processes such as concentration and dehydration.

The water purification process of a sewage treatment facility is usually performed in a water purification plant, and a physical water purification process that removes solid suspended substances (tree branches, plastic bottles, styrofoam, etc.) and solid precipitated substances (sand, gravel, metal, etc.), and organic matter. It includes a chemical/biological water purification process that removes soluble substances such as.

At this time, the chemical/biological purification process includes a process of forming a scum by administering a chemical to the raw water flowing into the coagulation pond in the water purification plant through the previous step, and then removing the scum from the raw water.

The conventional scum removal device is a device used to remove the scum from raw water, and is installed on both sides of the bulkhead of the coagulation pond in a water purification plant to remove scum floating on the inflowing water by providing a scum inlet at the upper side of the scum hopper. Is formed.

In addition, the scum removal device as described above is configured to manually adjust the height of the inlet of the scum hopper by installing a handle or a motor so that the scum floating on the water surface is discharged through the inlet.

In such a water treatment process, a large amount of scum floats on the surface of the treated water, and since such scum is not only visually good, but also adversely affects water quality, it must be removed from the treated water and then supplied.

On the other hand, the conventional scum removal device used for the above purpose fixes the scum removal device to the position of the water surface with an inlet formed on one side of the pipe, and corresponds to the position of the water surface that is electrically or manually changed, It was developed and used to be controlled.

However, the above method has disadvantages that the effect is not satisfactory due to the inconvenience of manually adjusting the height of the scum hopper constituting the scum removal device according to the height of the water in a situation where the state of the water surface changes from time to time. In a situation in which scum is discharged through an inlet port formed in the scum hopper together, a large amount of water is discharged together with the scum, so there is a problem in that water consumption increases.

In addition, there is a problem in that the efficiency of removing the scum on the water surface of the flocculating paper whose height fluctuates during scum removal is lowered.

Therefore, it is possible to easily adjust the height of the scum removal on the surface of the flocculating pond, and at the same time, the scum floating on the surface of the flocculating pond can be removed and the removed scum can be smoothly discharged together with the discharged water, through which the scum is discharged. Research and development of a scum removal device is required to maximize efficiency.
