The present invention relates to a device for purifying non-point pollutants in the initial rainfall runoff during rainy weather, and more specifically, to efficiently clean the non-point pollutants introduced with the initial rainfall runoff from the non-point pollutant, as well as to install them. The present invention relates to an apparatus for purifying nonpoint pollutants in early rainfall runoff, which enables efficient space and space.

In general, pollutants include point pollutants and agricultural lands, grasslands, forest lands, construction sites, mines, logging sites, waste disposal plants, garbage, etc., which are discharged from defined and limited point sources such as domestic sewage, industrial wastes, and livestock wastes. Discharge areas can be divided into nonpoint pollutants emitted from a wide range of nonpoint sources, such as landfills, roads, parking lots, plazas, bus stops, and dense residential areas.

Therefore, in the case of point pollutants having a clear and limited discharge point, separate purification devices or wastewater treatment facilities are installed in homes, factories, livestock farms, etc., but purification of pollutants is performed to some extent. Although the area remains unclear and extensive on the surface, it is a major cause of water pollution as it flows into public waters such as rivers, bays, lakes, and groundwater along with rainwater during rainy weather.

Therefore, in recent years, non-point pollutant treatment apparatuses for preventing the non-point pollutants from entering the public water or groundwater such as rivers, bays and lakes with initial rainfall have been provided.

However, such a conventional non-point pollutant treatment device has a lot of restrictions in place and space for installation.

That is, the non-point pollutant treatment device is required to be relatively large enough to receive and clean the initial rainfall flowing down with the nonpoint pollutant from the nonpoint pollutant within a certain range. it's difficult.

In particular, when the conventional non-point pollutant treatment device is to be installed in roads, parking lots, squares, bus stops, dense residential areas, it is more difficult to secure a place and space. I can't.

On the other hand, in order to solve the above problems, the scale of the non-point pollutant treatment device may be reduced, but in this case, the capacity of the initial rainfall effluent and the purification capacity of the non-point pollutant are reduced, so that the efficiency is not only lowered, but also relatively low. Maintenance is inconvenient because a large number of installations have to be made.

Therefore, due to the various problems described above, the active installation of the non-point pollutant treatment device is not performed at present, and a large amount of the non-point pollutant is introduced into the stream, the bay, the lake, etc. with the initial rainwater, causing serious water pollution. As a result, there is an urgent need for improvement.

The present invention has been proposed to solve the above problems and shortcomings, the main purpose of which is to efficiently clean the non-point pollutants introduced with the initial rainfall outflow from the non-point source, as well as the installation site and It is to provide a non-point pollutant purification device for the initial rainfall runoff that enables efficient space clearance.

A settling tank provided with a first filter member for smoothly discharging; The second drain pipe for discharging the rainfall runoff water is formed at the lower side while the rainfall runoff flows in from the sedimentation tank while being formed to be buried adjacent to the settling tank, and the rainfall introduced into the upper space of the second drain pipe. A filtration tank provided with a second filter member for smoothly discharging the filtered rainwater while filtering the non-point pollutants contained in the effluent; And partitioning the neighboring sedimentation tank and the filtration tank, wherein a plurality of inflow holes are formed on the upper side where the second filter member is installed to allow rainfall outflow water from the sedimentation tank to the filtration tank, and the upper end protrudes higher than the upper end of the precipitation tank. The partition wall formed to form a boundary stone of the sidewalk; is formed integrally.

At this time, the other end of the sedimentation tank formed on the other end is connected to the side channel is installed on the side of the road / parking lot, plaza, stop, etc. side exit channel is formed so that the initial rainfall runoff flows through the side channel is formed. .

In addition, first and second reservoirs are formed on one side where the first and second drain pipes of the precipitation tank and the filtration tank are first stored and discharged after first storing the rainwater purified through the first and second filter members.

In addition, the bottom of the settling tank and the filtration tank is formed with a non-inclined inclined surface of the bottom of one side, the first and second drain pipe is formed than the other bottom.

The first filter member may include a first nonwoven fabric and a first nonwoven fabric to cover an outer surface of the first drain pipe having a plurality of through holes, in a state where a plurality of through holes are formed on the first drain pipe exposed to the inner space of the settling tank. The second filter member is formed of a gravel layer having a uniform thickness on the outside, a second nonwoven fabric for covering the outer surface of the gravel layer, and a wire mesh for covering the second nonwoven fabric, while the second filter member is disposed at a step of the inner space of the filtration tank. And a filter media mat layer stacked on the second drain pipe in a transverse direction on the second drain pipe, and a zeolite filter layer stacked on the filter media mat layer.

In addition, a great portion of the sedimentation tank is installed so that the initial rainfall runoff can be smoothly introduced, while the bends of the filtration tank and the first and second reservoirs are provided with a steel plate to prevent foreign substances from penetrating.

Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

That is, the side channel 10 is a facility for guiding the rainwater 40 formed in the existing walkway / roadway boundary part to the sewer 40 in a wide space such as a road, a parking lot, or a square. The initial rainfall runoff, which falls on the source of pollution, smoothly flows into the settling tank 100 so that efficient collection and purification of non-point pollutants is achieved. Therefore, the other end of the settling tank 100 described above is in communication with the side channel 10 is formed with a side connection connector 130 is cut so that the non-point pollutant flows smoothly with the initial rainfall outflow.
