Nonpoint source rainwater treatment device connected to rain gutters

The present invention relates to a non-point source rainwater treatment device connected to a rain gutter installed in a road drainage channel to prevent rainwater (rainfall amount 5m / m) nonpoint source rainwater initially falling on a road surface. In addition, a non-point source rainwater treatment device is formed under the outlet of the rain gutter and connected to the outlet, and consists of a storage tank, a filtration tank, and an accessory cleaning container, and the non-point source rainwater having a rainfall of 5 m / m initially dropped on the road surface of the rain gutter. It is stored in a storage tank through an outlet, and slowly evaporated into the atmosphere by an evaporation wick through a filtration tank, penetrates into the ground by a drain wick, and drains it slowly, and an accessory cleaning container is formed to clean the storage tank and the filtration tank. Invention.

Rain gutters installed in the conventional road drainage polluted the rivers and the seas by allowing the rainwater falling on the road surface to flow into the rivers and the seas. Utility Model Registration No. 20-0343186, the non-point source treatment apparatus, induces rainwater to rainwater receivers installed on the road surface, and passes through the primary sedimentation tank → secondary sedimentation maintenance tank → discharge treatment tank → first filtration means → second filtration means. It is a treatment device that infiltrates rainwater into the ground. The non-point source treatment apparatus of Utility Model Registration No. 20-0343186 has a problem in that the non-point source rainwater penetrates directly into the ground, so that the drainage is not good, and the ground subsides and sinks.

Accordingly, an object of the present invention is to install rainwater with an initial rainfall of 5m / m on the road surface in order to prevent the rainwater rained on the road flows into the river or the sea through the rain gutter installed in the drainage along with the non-point source of the road Through the rain gutter, the non-point source rainwater treatment device is connected to the non-point source rainwater treatment device, and the nonpoint source rainwater treatment device is connected to the rainwater gutter which is drained deeply or shallowly into the ground and then drained and evaporated in the air to be treated. It is.

The present invention for achieving the above object, under the outlet of the rain gutter is installed in the drainage of the road, to prevent the rainwater source rainwater on the road surface to flow into the river and the sea through the rain gutter, installed in the drainage. The non-point source rainwater treatment apparatus for treating the non-point source contaminant which is connected to the outlet, is formed of a storage tank, a filtration tank, and a cleaning container, and the storage tank has a cylindrical shape, and has a cleaning device provided with a pedestal and a horse cap. The filter unit is connected to each other and the filter is formed by connecting a plurality of troughs are formed with a convex portion with a drain hole, the reservoir is connected to the reservoir and the transfer pipe is a cylinder with a lid, the filter inside is filled with a filter medium , The lid is provided with a plurality of wick holes through which the evaporation wick passes, the cylinder of the filtration tank The bottom and the bottom is provided with a plurality of wick holes through which the wick is passed. The cleaning container has a lid having a plurality of wick holes through which the evaporation wick passes through the square at the outside and the cylinder is inside, and is connected to the cleaning device of the reservoir at the side. There is a cleaning hole, the lower part is connected to the upper part of the lid of the filtration tank, it is installed and a plurality of evaporation wick is connected to the interior of the filter medium of the filtration tank, through the wick hole of the filtration tank lid, It is installed through the wick hole and exposed to the atmosphere, and a plurality of drain wicks are connected under the filter embedded in the inside of the filtration tank, and can be planted deeply or shallowly in the ground through the filtration tank cylinder and the wick hole at the bottom. In addition, the evaporation wick is an integrally formed overlap width, between which the plastic air bag is inserted The drainage wick is a long bag-shaped wick, the bottom end of which is embedded a flexible perforated tube with the royal end and charcoal filled in the perforated tube, the perforated tube formed in the whole lengthwise or partially Or it may be formed only on the bottom, characterized in that the outer peripheral surface portion of the drain wick can be covered with a plastic barrel. In addition, the evaporation wick connected to the inside of the filter medium of the filter tank is characterized in that the non-point pollutant rain water of the filter tank can be discharged to the atmosphere while the oil and harmful substances in the non-point pollutant rain water can be discharged. The filter can also be cleaned and the filter tank can be cleaned. In addition, non-point source rainwater on the road surface can be drained to the storage tank through the rain gutter, transported to the filtration tank, evaporated into the atmosphere by the evaporation wick, and slowly drained deeply or shallowly into the ground by the drain wick. There is a characteristic.

The non-point source rainwater treatment device connected to the rain gutter of the present invention can be connected to the rain gutter installed in the existing road drainage using less cost, and the effect of treating the non-point source rainwater on the road surface and prevent pollution of rivers and seas It is effective.

Each rain gutter installed in the road drainage can be connected at regular intervals (every ten, twenty, or thirty) without connecting non-point source rainwater treatment devices, resulting in excellent economic efficiency.

The reservoir has a strainer to filter soil and back, and there is a dust tank to clean the reservoir, strainer and filtration tank to prevent the soil and back from entering the filtration tank and to smooth the function of the non-point source rainwater treatment system. There is an effect that can be maintained.

The evaporation wick has the effect of evaporating the non-point source rainwater of the filtration tank into the air, and to discharge oil and harmful substances in the nonpoint source rainwater,

The drainage wick has the effect of slowly and evenly infiltrating non-point source rainwater filtered from the filtration tank into the ground slowly and shallowly, and also prevents the soil from acidification. The plastic air zone of the evaporation wick can supply air (oxygen) to the filtration tank and evaporate effectively, and the drain wick and oil pipes can filter non-point source rainwater once more and slowly and deeply penetrate deeply or shallowly into the ground. The plastic container covering a part of the outer circumferential surface of the drainage wick penetrates into the ground, thereby controlling the amount of rainwater discharged from the nonpoint source and allowing the nonpoint source rainwater to be evenly drained into the ground. In addition, it evaporates to the evaporation wick, drainage into the ground as a drain wick has the effect of slowly draining non-point source rainwater.
