Description

A rainwater storage device

technical field

The utility model relates to the technical field of rainwater collection and simple treatment, in particular to a rainwater storage device.

Background technique

The supply of tap water in many cities today is difficult to keep up with the pace of urbanization. Emerging water industries such as irrigation and greening, street watering, and car washing put more pressure on the supply of tap water. The flooding of rainwater when the rainy season comes every year causes great damage to the city's drainage system. impact, and even lead to urban flooding. Rainwater collection and treatment is a new technology in China. At present, the research on rainwater collection and treatment is in the initial stage. The existing rainwater storage devices generally directly settle the sediment in the rainwater, and then extract the clear water from the upper end. After the sand settles, it is still located in the same storage space as the purified water. During extraction, it is easy to stir the settled sediment, causing the purified water to become turbid again. Repeated filtration treatment is required for subsequent use.
