Rainwater treatment system with backflow odor prevention function}

The present invention relates to a rainwater treatment system with a backflow prevention function, and more specifically, when the stormwater water pressure stored in the main storage tank exceeds a predetermined pressure, it is temporarily opened to allow rainwater discharge, and when the stormwater pressure is lowered, This relates to a rainwater treatment system with a backflow prevention function that can closely block bad odors and the backflow of sewage during normal times by applying a closed backflow prevention header.

In general, drain structures, which are drainage structures, are installed at both ends of a road made of asphalt concrete pavement in the longitudinal direction of the road for the purpose of collecting and draining water from the road surface or adjacent slopes.

These gutters are formed of concrete structures, and their shapes are constructed in various ways considering various factors such as installation location, drainage volume, economic feasibility, and traffic stability. However, if the drainage capacity is exceeded due to heavy rain, the inner floor of the gutters The situation is that foreign substances, including tire dust, oil, heavy metals caused by automobiles, and tire wear particles, are flowing back.

Accordingly, in the previously disclosed patent registration number 10-1989601, a body having a hollow structure with an opening formed on one side and an empty interior; a rainwater inflow hole formed on the upper surface of the main body; a grating installed in the rainwater inflow hole to block foreign substances in the rainwater flowing into the rainwater inflow hole; a cylindrical rainwater storage tank installed by being inserted into the interior of the main body through the opening and having an open top to store rainwater flowing in through the rainwater inflow hole; a rainwater outflow pipe formed to protrude from the rainwater storage tank and coupled to a support groove provided in the main body so as to discharge rainwater stored in the rainwater storage tank to the outside of the main body; Rainwater discharge limiting means installed in the rainwater storage tank to block rainwater from being discharged through the rainwater outflow pipe during rainy weather, wherein the rainwater discharge limiting means is installed on the inner floor of the rainwater storage tank and has a receiving room inside. This formed base portion, a water passage opening formed in the lower part of the base portion to allow rainwater stored in the rain water storage tank to flow into the receiving chamber, and a water passage opening formed in the lower portion of the base portion, are formed to penetrate from the inside of the receiving chamber to the outside of the base portion and are located higher than the water passage opening. an outlet, a connection pipe connecting the outlet and the rainwater outflow pipe so that rainwater flowing into the receiving room can move to the stormwater outflow pipe through the outlet, and blocking the outlet when the water level of the rainwater storage tank is full. A technology including an outlet opening and closing unit that opens the outlet when the water level of the rainwater storage tank falls from the full water level to a certain level has been previously proposed.

However, the prior art is to store rainwater that flows into the interior during rainy weather and gradually discharge the stored rainwater into the ground after a certain period of time after the rain stops. However, civil complaints due to backflow of odor have resulted in rainwater storage tanks being full due to sudden heavy rain. When rainwater flows back to the outside, foreign substances accumulated inside are exposed to the outside, polluting the surrounding area.
