Description

A device for intercepting and purifying initial rainwater runoff in residential areas

technical field

The utility model relates to an ecological interception device, in particular to an initial rainwater runoff interception and purification equipment in residential areas.

Background technique

Rainwater is the main way to obtain water bodies on land. The initial rainwater is very clean, but with the development of industry, the current rainwater has been more or less polluted. If the polluted rainwater flows into rivers and lakes, it will seriously pollute other clean water bodies. Therefore, it is necessary to Purify the polluted rainwater. At present, in cities, due to the high concentration of pollutants in the initial rainwater, if possible, it will be set up to collect the initial rainwater and discharge it into the sewage pipe network for treatment. After the sewage needs to be collected through the sewage pipe network, it is sent to the sewage treatment plant for treatment. The water quality meets the corresponding national or local standards before being discharged into the river, which can prevent the river from being polluted. However, the current rainwater interception devices generally have the following problems. The first is that there are few facilities and outlets, and it is impossible to achieve all-round interception. Therefore, a lot of rainwater directly flows into the urban pipe network without purification; the second is the production and installation of these interceptors. The facilities will consume a lot of manpower and material resources, and occupy a lot of land. In addition, these facilities must be maintained regularly; the third is that these facilities can only function when there is rain, and they are idle most of the time. Fourth, These facilities do not produce other economic benefits and environmental protection effects except for purifying rainwater. In addition, because our country is in the process of economic development, if too many rainwater interception facilities are built, it will consume a lot of financial resources. Therefore, some experts and scholars who are dedicated to the study of initial rainwater purification hope to develop a simple and efficient initial rainwater interception. The device is used to divert, intercept and purify the initial rainwater in the living areas of urban residents. In the living quarters of modern cities, not only the residences are usually built into a multi-storey structure, but also the squares of the community are also built into a multi-storey structure, the bottom of which is usually an underground garage or storage room. Green plants, most of these green plants are planted in fillers with strong water permeability. These fillers can filter rainwater very well. Therefore, some experts and scholars who are committed to the ecological interception and purification of rainwater hope to combine and effectively use the green belts of residential areas, Parking lot and unused underground garage, thus creating a beautiful and practical rainwater diversion and interception treatment facility in the living area of residents.
