In cities, the collected rainwater can be divided into roof rainwater, green land rainwater and road surface rainwater according to the properties of the underlying surface. When raining, pollutants on the roof and the atmosphere are collected to the road surface under the action of rain wash, and according to research results of related documents, the pollutants of the rainwater runoff of the road surface are very complex, the pollution degree is severe, the treatment is difficult, and the cost is high; rainwater collected by the lawn and the green land has good quality; the urban roof rainwater is only influenced by the roof and pollutants in the atmosphere, and the water quality of the urban roof rainwater is obviously superior to that of road rainwater. Considering that the penetration capacity of the lawn and the green land is strong, the amount of collected rainwater is very limited, and the rainwater penetration mode of the lawn and the green land is more reasonable, so that the rainwater on the roof is often collected and recycled in the actual implementation process of the sponge city. The initial runoff pollution of roof rainwater is serious, main pollutants are SS and the like, the biodegradability is poor, and biochemical treatment is not suitable. Traditional roofing rainwater collection device often only has simple filtration, deposits and stores the function, often can only filter or deposit solid rubbish of large granule such as debris, leaf at the in-process of in-service use, and purification performance is limited. Therefore, the initial rainwater is usually abandoned to flow to a sewage pipe network at present, and only the later rainwater is collected.

However, after the initial rainwater with low biochemical property is collected into the sewage pipe network, the initial rainwater not only occupies the drainage capacity of the original sewage pipe network, but also influences the quality of inlet water of a sewage treatment plant, thereby increasing the load of the sewage treatment plant.
