China is now in a period of rapid development of urbanization. The population and wealth are continuously concentrated in cities, and the urban area is getting larger and larger. With the continuous acceleration of the urbanization process, the building density in the city is also increasing. The impact on people's daily life is also becoming more and more obvious. The storm drain is not only the throat of the urban drainage system, but also an important channel for the urban non-point source pollution to enter the water environment. Once blocked, it will not only lead to poor drainage and even cause water accumulation on urban roads, but also cause pollution to urban water bodies. Surface runoff pollution is one of the important sources of urban non-point source pollution. In order to reduce the pollution load of urban road flow, sewage interception and purification facilities can be set up in the rainwater outlet to reduce the discharge of pollutants from the source. Therefore, it has become increasingly important to use the rainwater outlet to reasonably control pollutants (such as toxic heavy metals and other elements) in the water. However, the existing rainwater outlet sewage discharge device has a simple structure, only has the sewage discharge function, and rarely has the sewage discharge device that simultaneously realizes the water purification function, which cannot be applied to the rainy season and the dry season at the same time. In addition, the flow of rainwater cannot be adjusted according to the actual situation. , In addition, when replacing the filter device, there is no filter component at the position of the rainwater inlet, and the rainwater is directly discharged into the sewer without filtering, which is likely to cause water pollution.

The Chinese invention patent with the patent application number CN201510731824.0 discloses a suspended rainwater inlet automatic overflow sewage interception device, including a water collecting tank, the upper part of the water collecting tank is provided with a card seat, and the upper part of the water collecting tank inside the card seat is provided with A handle, a suspension balance device is arranged in the water collecting tank, the suspension balance device includes a support rod and a suspension isolation cover, the suspension isolation cover is connected with the support rod by a connecting piece, and a sewage interception device is arranged under the card seat , The automatic overflow sewage interception device can prevent the blockage of rainwater inlets and rainwater pipes, improve the drainage capacity of rainwater pipes, control pollutants through the source of rainwater pipes, reduce the treatment pressure of sewage treatment plants and the pollution of urban water bodies by runoff pollutants, and can realize rainwater inlets. Double function of overflow and interception.
