Description

Moss removal device for sewage treatment plant

The present invention relates to a moss removal device for removing the moss generated in the purified water passage for the purified water flowing in the final sedimentation basin of the sewage terminal treatment plant, in particular, the bottom and both sides of the purified water passage can be easily cleaned as well as curved areas In addition, the present invention relates to a moss removal device for a sewage terminal treatment plant that is capable of extending a life cycle by preventing contact with purified water when not in use.

In general, sewage terminal treatment plants collect wastewater from industrial fields such as paper mills and dyeing plants that generate pollutants, and household sewage from households in a certain place to naturally purify (precipitate), or microorganisms and various chemicals. It is installed to forcibly remove contaminants.

Such sewage treatment plants usually allow the wastewater or household sewage introduced into the large-sized purification section to gradually purify by the administered microorganisms or chemicals while allowing natural wastewater (sedimentation) to flow through the purification section at a slow rate. Then, the purified water is discharged to the outside through the purified water passage formed at a predetermined depth along the edge of the purifying unit, although the water flowing through the purified water passage is completely purified, but after a predetermined time, moss is generated in the purified water passage and completely purified. There was a problem that the degradation of the image for the integer and acute, the distrust of the integer itself is amplified.

Thus, in order to remove the moss caused by the purified water flowing through the purified water passage, in the past, the worker went into the purified water passage to remove the moss manually by hand, but in this case the operation is difficult, the moss removal is not properly performed, safety accident The danger was inherent. The moss trapped in the water purification passage along the traveling bridge that is circularly moved at a very slow speed is connected to the traveling bridge installed across the sewage treatment plant, with a self-driving means for driving several brushes in the water purification passage. The cleaning device is simple and coarse to remove only the moss formed on the bottom part of the water purification passage. In particular, even when not in use, it always comes into contact with the purified water filled in the water purification passage. This causes a problem that the life cycle of the cleaning device is shortened.

Accordingly, the present invention has been devised to solve the above problems, and can easily clean the bottom and both sides as well as the curved portion by using its own driving force, and prevent contact with purified water when not in use. The purpose is to provide a moss removal device for sewage terminal treatment plant that can extend the life cycle (Life Cycle).
