Among the 600 cities in my country, 300 are short of water, and more than 100 are seriously short of water, and the trend is on the rise. For this reason, the state has spent huge sums of money on the South-to-North Water Diversion Project, but it can only meet the needs of some areas. In addition, urbanization has replaced the original vegetation and soil with impermeable ground, causing a large amount of rainwater to be lost, destroying the natural ecological and hydrological environment, and groundwater cannot be effectively replenished. Decrease year by year, the ecological environment of the city deteriorates, the water content in the soil decreases, the heat island effect intensifies, the air is dry, and when it rains, due to the low permeability of urbanized rainwater, the rainwater accelerates to collect in the city's rivers, and the peak flow quickly forms. Urban drainage facilities The load increases, and flood disasters occur frequently.

Rainwater is a clean water source. How to comprehensively utilize and control resources has far-reaching significance for human settlements and water ecology. At present, more and more countries have begun to pay attention to collecting clean rainwater. Rainwater collection usually uses roofs, ground roads, green spaces, natural hillsides, etc., and the initial rainwater is mixed with a large amount of suspended matter (branches, leaves, foam, plastic films, paper scraps, etc.) etc.) particulate matter (broken bricks, mud, sand, etc.), therefore, the initial rainwater should be intercepted and collected, and the impurities in the rainwater should be filtered and removed to ensure the normal operation of the later water storage system and ensure the safety of drainage; and now the rainwater is mixed with suspension When dust and particles enter the rainwater disposal device, it may contain a large amount of metal impurities, and tiny metal impurities can pass through the filter screen to make the rainwater filtration not clean enough.
