Embodiment Construction

[0025] The application will be described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific embodiments are only used to further illustrate the application, and cannot be interpreted as limiting the protection scope of the application. The above application content makes some non-essential improvements and adjustments to this application.

[0026] combine Figure 1 to Figure 4 As shown, a biological treatment system for rainwater purification in a sponge city, the biological treatment system is located under the road surface 1 and the green areas 2 on both sides of the road surface 1, the biological treatment system includes a sedimentation tank 3, a reservoir 4 and a biological purification layer 5. The sedimentation tank 3 is located directly below the road surface 1, and is used to receive the rainwater seeping through the road surface 1 and the green area 2. The overflow pipe 6 is provided in the ...

Abstract

The invention discloses a biological treatment system used for rainwater purification of a sponge city. The biological treatment system is arranged on a road surface and below greening regions of thetwo sides of the road surface, and comprises a settling pond, a water storage pool and a biological purification layer, the settling pond is located under the road surface and used for receiving rainwater which seeps from the road surface and the greening regions, an overflow pipe is arranged inside the settling pond, the water storage pool is communicated with the settling pond through the overflow pipe and used for storing the rainwater which overflows from the settling pond, and the biological purification layer comprises a road surface biological purification layer arranged at the bottom of the road surface and greening region biological purification layers arranged at the bottoms of the greening regions; a water-permeating road surface is adopted as the road surface, and permeable soil is adopted for the greening regions. The biological treatment system has the advantages that the road surface and the greening regions of the city are arranged to be of permeable structures, the rainwater will directly permeate into the ground, no water accumulation on the road surface occurs, convenience is provided for vehicle driving and passerby walking, the rainwater is fully purified during permeating, and the stored rainwater has more purposes.

Description

technical field [0001] The invention relates to the technical field of sponge city construction and sewage treatment, in particular to a biological treatment system for rainwater purification of the sponge city. Background technique [0002] In recent years, waterlogging every time it rains has gradually evolved into a chronic disease in large and medium-sized cities in my country, and many cities with severe water shortages have lost 70% of their rainwater in vain. It is a pity, but the concept of sponge city has perfectly solved this problem. 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. "Come out and take advantage of it. [0003] At the same time, the treatment of the rainwater collected by the sponge city has become an urgent problem to be solved. The pollution situation of each city is different. The rainwater in cities with a good environment is relatively cl...
