technical field

The invention relates to the technical field of sponge cities, in particular to a new type of rainwater treatment system for sponge cities.

Background technique

Sponge city is a new generation of urban stormwater management concept, which can also be called "water elastic city". The international term is "low-impact development of rainwater system construction", which absorbs water, stores water, seeps water, and purifies water when it rains, releases and utilizes the stored water when needed, and realizes the free migration of rainwater in the city. Building a sponge city, making overall use of natural ecological functions and artificial intervention functions, effectively controlling rainwater runoff, and realizing the urban development mode of natural accumulation, natural infiltration, and natural purification is conducive to restoring urban water ecology, conserving water resources, and enhancing urban waterlogging prevention capabilities.

In the novel sponge city rainwater treatment system disclosed in this embodiment, a water seepage well 2 is embedded in the ground layer 1. When the amount of precipitation is low, the precipitation penetrates into the ground layer 1 and then enters the water storage cavity 5. The fixed plate 3 penetrates into the water seepage well 2, and enters the water storage cavity 5 after being filtered by the coarse filter assembly. The precipitation in the water storage cavity 5 enters the reuse cavity 8 again; the precipitation in the first water supply cavity 11 of the reuse cavity 8 is filtered. After the plate 10 is filtered, it enters the second water supply chamber 12. The water in the first water supply chamber 11 is relatively clean but the cleanliness is insufficient. It can be used as cooling and circulating water in industrial production. The water in the second water supply chamber 12 is filtered and cleaned again. It can be used as the living water supply for residents to wash cars, flush toilets, etc. for urban residents; when the precipitation is large and exceeds the circulation of ground floor 1 and fixed plate 3, there will be deep water accumulation on the ground. When the lifting plate 4 is separated from the fixed plate 3, the flow of the fixed plate 3 is greatly increased, the water level in the seepage well 2 rises, and is higher than the position of the one-way valve 6, and the pressure of the water pushes the one-way valve 6 to the water storage cavity 5 is turned on, increasing the water flow from the seepage well 2 to the water storage cavity 5.
