Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scum removing device installed on a sedimentation basin settling tank for purifying waste water and wastewater to remove scum floating on the water surface of treated water, Which requires little maintenance.
As the national income increases and the living and living standards are improved, various kinds of wastewater flowing into sewage are increasing. These wastewaters pollute rivers, rivers, and lakes greatly and are becoming social problems.
Generally, a variety of sewage and wastewater treatment plants for purifying various wastewater have been proposed and widely used so far, and the treatment methods most commonly used among wastewater treatment methods are as follows.
When wastewater flows into the sewage treatment plant, firstly, relatively bulky substances such as sand, gravel, wood chips and cans contained in the sewage are removed from the settlement.
Sewage water passing through the gypsum is uniformly mixed in the flow rate control tank, and the flow load is buffered by the increase or decrease of the inflow of sewage water, and the microorganisms are transported to the sedimentation basin by a predetermined amount to maintain proper environment for biological sewage treatment using microorganisms.
The sewage transported in the flow control tank by a constant amount removes heavy materials and light materials from the first sedimentation tank.
The pollutants in the sewage that have not been removed by sedimentation in the initial sedimentation basin are decomposed by aerobic microorganisms in the aeration tank and the microorganisms and contaminants form flocs and sink in the next process, the final sedimentation basin.
In the aeration tank, the flocs formed by the aerobic microorganisms are settled again in the final settling basin. Unlike the initial settling basin, the clear basin is obtained and discharged into the stream.
As described above, the wastewater flowing into the sewage treatment plant is treated in a state in which the wastewater flowing into the sewage treatment plant is continuously flowing, and thus, many scum floats are generated on the surface of each sedimentation tank.
In order to remove the scum on the surface of the sedimentation water, the

In the scum removing device of the present invention having the above-described structure, the height of the scraper and the collecting device is dynamically controlled by using an ultrasonic flow meter. By using the limit switches on both sides, It becomes possible to repeatedly remove scum by sweeping.
Particularly, a side bending portion is formed in the blade, and a bubble water nozzle is provided to wash the scum along the both side walls during the operation of the scraper so that the scum is not deposited.
In addition, by placing the front sub-panel or the front projection on the front of the scum collecting device, the scum conveyed by the blade can be completely collected into the scum collecting device.
