Rainwater pollution intercepting and purifying device for sponge city

Abstract

The invention discloses a rainwater pollution intercepting and purifying device for a sponge city. The rainwater pollution intercepting and purifying device comprises a grass swale and a rainwater pollution intercepting hanging basket, wherein sunken green land is arranged at the lower end of the grass swale; in addition, a rainwater total header is connected to the lower end of the sunken green land; a sewage draining exit is formed in the bottom end of the rainwater pollution intercepting hanging basket; besides, a filtering device is arranged on the right side of the rainwater pollution intercepting hanging basket; a filtering plate is arranged inside the filtering device; a pollution accumulating groove is fixed in the front end of the filtering plate; a rotating shaft is arranged on the surface of the filtering plate; activated carbon is arranged on the right side of the filtering device; a nitrogen and phosphorus removing ball layer is arranged inside a water collecting basin; in addition, a water softening device is fixed at the bottom end of the water collecting basin; and concave bosses are separately arranged at the upper ends and the lower ends of a stainless steel filtering screen and the filtering plate. One part of pollutants attached to the filtering plate can be transferred inside the pollution accumulating groove by rotation of the rotating shaft arranged on the rainwater pollution intercepting and purifying device for the sponge city, thereby preventing pollutants from blocking the filtering plate and increasing the flowing speed of water.

Description

technical field [0001] The invention relates to the technical field of sponge city devices, in particular to a rainwater interception and purification device for sponge cities. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. Utilization, in the process of sponge city construction, the systematic nature of natural precipitation, surface water and groundwater should be coordinated, water supply, drainage and other water recycling links should be coordinated, and its complexity and long-term nature should be considered. [0003] The existing rainwater interception and purification devices in sponge cities cannot collect water resources well, and it will still cause the loss of water resources, and larger objects will be blocked by interceptors during filtration, which will affect the speed of water filtration and the degree of water purificati...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a rainwater interception and purification device for sponge city to solve the problem that the existing rainwater interception and purification device for sponge city in the market cannot collect water resources well or cause water pollution. The loss of resources, and when filtering, larger objects will be blocked by interceptors, which will affect the speed of water filtration, and the degree of water purification is low, and being eaten by people will affect people's health.
