The recycling of building rainwater usually involves setting up recycling pools or recycling tanks to store rainwater, and then filtering it according to the needs for subsequent use in production and life. my country is promoting the construction of sponge cities in cities, and has put forward regulations on the recycling and utilization of rainwater according to different regions. Sponge cities refer to an urban development model that strengthens urban planning and construction management, gives full play to the absorption, storage, infiltration and slow release of rainwater by ecological systems such as buildings, roofs, green spaces, and water systems, effectively controls rainwater runoff, and realizes natural accumulation, natural infiltration, and natural purification. In the construction of water conservancy projects, rainwater recycling is generally achieved by building a filter pool, which will have a filter device to filter impurities in the rainwater.
