Embodiment 1

[0046] Embodiment 1 of the present invention is: a water storage and slow-release module 1 dedicated to sponge cities. The water storage and slow-release module 1 is formed by mixing polyethylene and activated carbon at a mass ratio of 10:1 and then pressing. The polyethylene is UHMWPE. The water storage slow-release module 1 is a cuboid structure surrounded by a top plate 11, a bottom plate 12 and four side plates 13, and the inside of the cuboid is the water storage space.

[0047] Such as figure 1 As shown, the top board 11, the bottom board 12 and the four side boards 13 respectively include a frame 131 and several reinforcing rib frames 132 of a hexagonal structure are tiled inside the frame 131, such as figure 2 As shown, there is a common side between every two adjacent reinforcing ribs 132; in addition, the frame 131 also includes reinforcing ribs 132 of incomplete hexagonal structure, top plate 11, bottom plate 12 and four side The length and width of the plate 13 ca...

Embodiment 2

[0050] Embodiment 2 of the present invention is: a water storage and slow-release module 1 dedicated to sponge cities. The water storage and slow-release module 1 is formed by mixing polyethylene and activated carbon at a mass ratio of 10:1 and then pressing. The polyethylene is UHMWPE. The water storage slow-release module 1 is a cuboid structure surrounded by a top plate 11, a bottom plate 12 and four side plates 13, and the inside of the cuboid is the water storage space.

[0051] The method of using the above-mentioned water storage and slow-release module 1 for urban rainwater harvesting includes the following steps:

[0052] S1. After the foundation treatment of the construction site (digging out a suitable size pit, laying sand 4 on the original soil 3 at the bottom as the base), paving high-density polyethylene (High Density Polyethylene, HDPE) geomembrane ( or activated carbon non-woven fabric);

[0053] S2. According to the needs of the project, take an appropriate...

Abstract

The invention discloses a water storage and slow release module special for a sponge city. The water storage and slow release module is formed by mixing polyethylene and activated carbon at a mass ratio of (8-15):1 and then pressing the mixture. The water storage and slow release module is of a hexahedral structure which is formed by a top plate, a bottom plate and four side plates, and a water storage space is formed in the hexahedral structure. The top plate, the bottom plate and four side plates include frames respectively, a plurality of reinforced rib frames of the hexagonal structures are laid in the frames, and every two adjacent reinforced rib frames share one common side. Compared with the prior art, the module has the advantages that the water purification effect is good and theperformance is stable.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a water storage slow-release module dedicated to sponge cities. Background technique [0002] Rainwater is a precious natural fresh water resource, however, the rainwater in the prior art has not been rationally utilized. In recent years, with the rapid development of urbanization in China, the groundwater level has dropped at an alarming rate, urban waterlogging has become a hot issue of concern, and the road traffic system is a high-incidence area for waterlogging. The low standard of urban drainage and the lack of rainwater utilization system are the main reasons why resources become disasters. Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called a water elastic city". Water abs...
