The present invention relates to an apparatus for removing a contaminant, and more particularly, to an apparatus for removing a contaminant having an improved structure.

At present, global water shortage is a major issue in many countries, and Korea has also been unable to neglect it. In order to solve this water shortage, we have found ways to efficiently manage, secure and utilize water in various ways. There is a situation.

Therefore, in order to solve the water shortage phenomenon, various methods for efficiently using rainwater falling naturally have been researched and developed.

However, such rainwater is exposed to various pollutants in the atmosphere and falls down, including the rainwater, and the ground surface is permeated with various pollutants, and thus, the pollutants contained in the rainwater are removed to improve the water quality of the streams. In order to achieve this, there is a need for an excellent purification facility.

The sewage treatment system in sewage pipes requiring excellent water purification facilities as described above is classified into a confluence type and a classification type, and consolidation sewers are transported to the sewage treatment plant for the total amount of sewage discharged in Cheongcheon, but in rainy weather As the discharge increases, a certain amount (maximum amount of planned wastewater) is transported to the sewage treatment plant through the conduit, and more is discharged from the stormwater to the public water.

At this time, the discharge load of the sewage that is not purified in rainy weather in the combined sewerage is the cause of water pollution in public waters, so it is required to take countermeasures.

In the conventional combined sewage pipe, the technology for purifying the overflow water has been difficult to maintain due to the use of a complicated device or the size of the device.

In addition, due to the large size of the facility, it is practically difficult to apply in large cities or urban areas where a large installation space cannot be secured, and it cannot be applied in a classification sewer pipe or a target area for treating a nonpoint source.

Therefore, there is a need for a purification treatment facility that can be used in an area where the system of combined sewage and sewage sewers is shared.

On the other hand, as a technology to purify the initial excellent water, the conventional sewage treatment method has used fixed screens such as coarse screens and finewood screens, but due to the characteristics of the rainwater treatment system, it is impossible to assign manpower for regular maintenance, so if the occlusion occurs, There was a problem that the device became insoluble.

In addition, in order to remove the sediment, if a sewage tank or similarly, a weir or a barrier wall is installed to treat the sediment through the water trapping function, water accumulates in the storage tank and the processing apparatus even after the rainfall is over. Odor is generated, and thus, the apparatus for the purification treatment has often become a source of pollution.

In addition, in the case of the initial excellent treatment apparatus by the filtration method and the adsorption method, there is a problem that the backwashing is impossible, so that the efficiency of the purification device decreases rapidly or the life is short.

On the other hand, in the rainwater purification facilities as described above, to remove the large solids, small solids, and other contaminants such as suspended solids primarily, but in the conventional rainwater purification facilities there is no separate debris removal device 1 There was a problem that can not remove the secondary impurities.

Moreover, even in the conventional stormwater purifying facility, even if a debris removal device is provided, a large debris was passed as it is not provided with a removal device for large debris.

Therefore, in the conventional stormwater purification facility, even if the debris removal device is not provided or is equipped, in particular, the large debris passes as it is, and the efficiency of the purification treatment device is significantly reduced, and thus, the purification device is lost. There was a problem that the life of the shortened.

In order to solve the above problems, it is an object of the present invention to provide an apparatus for removing impurities, which increases the efficiency of the purification treatment and enables semi-permanent use of the purification treatment facility.
