Description

A green roof rainwater collection and recycling system based on traditional sponge wisdom

technical field

The utility model relates to the technical field of water circulation systems, in particular to a green roof rainwater collection and recycling system based on traditional sponge wisdom.

Background technique

In recent years, flooding every time it rains has gradually become an urgent problem to be solved in many cities. At present, many cities adopt the fast drainage mode. After the rainwater falls on the hardened ground, it can only be quickly discharged from the pipes. This mode makes 70% of the rainwater in the city go to waste. If most of the rainwater is kept instead of drained, It can maximize the accumulation, infiltration and purification of rainwater in the urban area, and promote the utilization of rainwater resources and the protection of the ecological environment. That is to say, the construction of sponge city is expected to digest the large amount of water that was originally discharged to the end of the pipes and canals in advance through absorption, storage, infiltration and other links, and become an effective way to solve the problem of waterlogging every time it rains, rather than relying on repairing large drainage pipes.

The international lingua franca of sponge city is "construction of rainwater system for low-impact development", that is, absorbing, storing, infiltrating, and purifying water when it rains, and releasing the stored water and using it when needed. Under the premise of ensuring the safety of urban drainage and waterlogging, the sponge city maximizes the accumulation, infiltration and purification of rainwater in the urban area, and promotes the utilization of rainwater resources and the protection of the ecological environment. Such as rivers, lakes, ponds and other water systems, and urban supporting facilities such as green spaces, gardens, and permeable pavements. Rainwater infiltrates, stores, purifies, and reuses rainwater through these "sponge bodies", and finally the remaining part is discharged through the pipe network and pumping stations, thereby effectively improving the standard of urban drainage systems and reducing urban waterlogging pressure.

But on the one hand, with the development of the city, the impermeable ground in the urban area, such as: cement ground, granite ground, etc., is getting bigger and bigger, and the infiltration capacity of rainwater is greatly reduced, resulting in the continuous increase of rainfall surface runoff, and the urban drainage system It has been greatly tested, posing a great threat to the normal production and life of the city. At the same time, due to the decline of rainwater infiltration capacity, groundwater cannot be well replenished. The decline of groundwater level not only affects the growth environment of ground vegetation, but also causes serious geological disasters.

At present, in most areas of our country, we are still facing a serious shortage of water resources. Rainwater is a precious fresh water resource, which is less polluted and can be used as miscellaneous water sources such as greening and car washing after simple treatment. Under the situation of increasingly serious water shortage, rainwater collection and utilization are becoming increasingly important. Rainwater collection and utilization can not only open up new water sources, save urban water resources, but also reduce the amount of rainwater surface runoff and reduce the risk of rain and flood disasters. , and achieved significant economic, social and environmental benefits.
