Description

Storm Water Treatment Device {Apparatus for treating rainwater}

The present invention relates to a stormwater treatment apparatus, and more particularly, to a stormwater treatment apparatus including anti-corruption means to prevent the water, including the stored rain water to rot by submerged sludge.

In general, when it rains, rainwater flowing to the ground will seep into the ground or evaporate. However, the destruction of the soil ecosystem due to excessive soil pavement such as urban development and redevelopment due to industrial development deepens the city's heat island and blocks the penetration of rainwater, resulting in urban flooding and groundwater depletion. This results in a vicious cycle that causes changes in the soil ecosystem.

In particular, there is a growing number of water shortages in Korea, where rainfall is concentrated in summer and dry weather in autumn and winter leads to droughts. In addition, the demand for water has increased due to the rapid increase in population and urban concentration, and controversy over the right to repair due to the lack of water in certain areas is occurring. In addition, the construction of dams, which is a solution for water supply, is facing difficulties in the construction of residents and environmental groups.

Therefore, the method of using rainwater or rainwater is emerging as an alternative for efficient water management and water acquisition and utilization. In other words, the rainwater collected in rainy weather can be collected, purified, stored and used as water for the dry season, and during the summer season when rainfall is concentrated, it can be expected to prevent the backflow of sewage pipes or flooding of the bank due to rainwater. There is a growing interest in stormwater treatment systems.

The stormwater treatment system generally includes a water collecting device for collecting rainwater, a purification device for purifying collected rainwater, and a storage tank for storing purified rainwater. By the way, when the rainfall is heavy, as described above, the rainwater is stored in the drainage after storing rainwater, so the rainwater should be stored for many months, causing problems such as moss in the water stored in the storage tank or rotting.
