Embodiment 1

[0037] Embodiment one sees figure 1 with figure 2 As shown, a wetland system integrating rainwater collection, regulation and storage, and purification is suitable for rainwater management in residential quarters in the construction of sponge cities, including landscape pool 1 and three-level wetland nested outside the landscape pool from inside to outside 4. The secondary wetland 3, the primary wetland 2 and the permeable concrete pavement 5 nested outside the primary wetland; the setting width of the primary wetland, secondary wetland and tertiary wetland is 100-300cm; the landscape The pool is a circular pool body, and the third-level wetland, the second-level wetland, the first-level wetland and the permeable concrete pavement are all circular and nested in the periphery of the landscape pool in sequence; the first-level wetland and the second-level wetland It communicates with the first communication pipeline 6, the first communication pipeline is at least one, and is a...

Embodiment 2

[0056] Embodiment two see image 3 As shown, the difference from Example 1 is that the landscape pool is a polygonal pool body, and the third-level wetland, the second-level wetland, the first-level wetland and the permeable concrete pavement are all in the form of closed polygonal strips, which are in the same shape as the landscape pool body. have the same shape and are nested in turn around the landscape pool.

Embodiment 3

[0057] Embodiment three see Figure 4 As shown, the difference from Embodiment 1 and Embodiment 2 is that the landscape pool shown is a circular pool body, and the third-level wetland, the second-level wetland, the first-level wetland and the permeable concrete pavement are arranged in modules, and along the landscape pool It is arranged at intervals in the ring direction, and an open hydrophilic space is left between adjacent modules.

[0058] The construction method of the wetland system integrating rainwater collection, regulation and storage, and purification:

[0059] Step 1, constructing the viewing pool;

[0060] Step 2, install an overflow pipe on the wall of the viewing pool, and connect the overflow pipe with the municipal rainwater pipe network;

[0061] Step 3: Construct a third-level wetland along the circumference of the viewing pool;

[0062] Step 4, setting up second connecting pipelines at intervals outside the third-level wetland;

[0063] Step 5, constru...

Abstract

The invention provides a wetland system integrating rainwater collection, regulation and storage, and purification. The wetland system comprises a landscape pond, a third-level wetland, a second-level wetland and a first-level wetland nested at the outer side of the landscape pond in the sequence from inside to outside, and a water-pervious concrete pavement nested at the outer side of the first-level wetland, wherein the first-level wetland communicates with the second-level wetland through first communicating pipelines, the second-level wetland communicates with the third-level wetland through second communicating pipelines, the first communicating pipelines and the second communicating pipelines are arranged in a staggered manner, a horizontal overflow pipe is arranged at the upper end of the inner wall of the landscape pond, and the overflow pipe communicates with a municipal rainwater pipe network. With the wetland system integrating rainwater collection, regulation and storage, and purification, the problems that during rainfall of existing communities, water accumulates on the road surface, while for landscape water, a water source is in shortage, and the water quality is difficult to maintain, are solved, and meanwhile, an important role is played for alleviating urban water logging.

Description

technical field [0001] The invention relates to the field of rainwater treatment, in particular to a wetland system integrating rainwater collection, storage and purification and a construction method thereof. Background technique [0002] my country is a country seriously short of water resources, and the per capita water resources are only equivalent to 1 / 4 of the world's per capita. More than 400 of the 668 cities across the country are short of water, of which 110 are seriously short of water. The national civil building water-saving design standard (GB50555-2010) stipulates that "the water source of landscape water shall not be municipal tap water or underground well water", so it is very difficult to maintain the water quality and quantity of landscape water. However, at the same time, rainwater resources are severely wasted. The rainwater is concentrated and discharged through the drainage pipe network, which puts a lot of pressure on the municipal pipelines, and urb...
