Description

Technical Field

[0001] The utility model relates to the technical field of environmental engineering, in particular to a device for collecting, purifying and reusing urban landscape rainwater. Background Art

[0002] In the process of rainwater recycling and utilization, when collecting rainwater, impurities such as leaves, branches and dust in the rainwater are first intercepted through a filter net, and then the rainwater is further purified by activated carbon, zeolite and expanded clay purification materials in the purification pool. The purified rainwater can be used for irrigation of urban landscape greening.

[0003] As the first line of defense for intercepting rainwater impurities, the filter is the first to come into contact with rainwater. For example, in the urban landscape rainwater collection, purification and reuse system with authorization publication number CN210507749U, a sewage interception device is provided on the upper part of the rainwater collection pool. The sewage interception device can adopt structures such as a grille net and a filter net, which can intercept some mud and larger impurities. However, in non-rainy weather, the filter net that is continuously exposed to the outside is easily affected by high or low temperature environments, which can cause aging, deformation, and rupture of the filter net material. In addition, its surface is easily contaminated by impurities in the air due to long-term exposure to the outside, thereby reducing the filtering effect and service life of the filter net, further affecting the collection and purification of rainwater.
