Background

The low-rain areas are sunken into the green lands as a part of sponge city implementation, water can move more naturally in the cities by 'collecting, storing and purifying' through the sunken green lands, ecological management and control and regulation of surface runoff rainwater are achieved, high-quality underground water resources can be recycled, and the method is particularly urgent and important. The traditional urban green land soil is affected by excessive human activities and some foreign invaders, the physical properties of the soil are remarkably changed, the variation of the infiltration rate is very large, and the infiltration rate of most of the green land soil is low. The storage and purification effects of the green plants and the soil are not obvious, and the aim of thorough purification is difficult to achieve. Most of the traditional green land surface runoff rainwater is naturally collected and is directly discharged into rivers and lakes by virtue of the original urban pipe network, so that the rainwater cannot be well stored in the local soil, and underground water resources cannot be fully utilized.

To achieve these objects and other advantages in accordance with the purpose of the invention, a rainwater storage and pollutant purification system is provided, which comprises, in order from top to bottom: a planting layer, a soil layer, an artificial filler layer and a gravel layer;

the soil layer is made of artificial macroporous soil, and an infiltration medium for improving the infiltration rate of rainwater and an organic modifying agent for improving the soil interception capability are added into the soil layer.

Preferably, the soil layer is formed by adding a soil loosening agent to increase soil porosity.

Preferably, trees and herbaceous plants with water storage and purification functions are planted in the planting layer.

Preferably, a perforated flow guide pipe is communicated with the lower part of the gravel layer, and the other end of the perforated flow guide pipe is communicated with a rainwater purification device.

Preferably, the rainwater purification apparatus includes: the first purifying tank, the second purifying tank communicated with the first purifying tank and the storage tank communicated with the second purifying tank.

Preferably, the inlet and outlet department of first purifying pond all is equipped with the filter screen, just be equipped with the chlorine piece in the first purifying pond, be equipped with reverse osmosis unit in the second purifying pond, and the exit is equipped with the activated carbon layer.

The utility model discloses at least, include following beneficial effect: the utility model provides a rainwater storage and pollutant clean system, it is through chemical means, and artificial soil macropore has improved the infiltration rate that the rainfall got into soil, and the water that gets into in the soil just bypasses most soil matrix for the response speed of groundwater, the adoption is changing soil decontamination degradation ability having the modifier, improves and improves the greenery patches and cuts dirty function, purifies groundwater.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Detailed Description

The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses a more detailed description of the present invention, which will enable those skilled in the art to make and use the present invention. In the drawings, the shape and size may be exaggerated for clarity, and the same reference numerals will be used throughout the drawings to designate the same or similar components. In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, and the like are used based on the orientation or positional relationship shown in the drawings. In particular, "height" corresponds to the dimension from top to bottom, "width" corresponds to the dimension from left to right, and "depth" corresponds to the dimension from front to back. These relative terms are for convenience of description and are not generally intended to require a particular orientation. Terms concerning attachments, coupling and the like (e.g., "connected" and "attached") refer to a relationship wherein structures are secured or attached, either directly or indirectly, to one another through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise.

As a specific embodiment of the present invention, refer to fig. 1, the present invention provides a rainwater storage and pollutant purification system, which comprises in order from top to bottom: a planting layer 11, a soil layer 12, an artificial filler layer 13 and a gravel layer 14;

the soil layer 12 is artificial macroporous soil, soil pores of the soil layer 12 are increased by adding a scarifier, and an infiltration medium for improving the infiltration rate of rainwater and an organic modifier for improving the soil interception capability are added into the soil layer 12. The infiltration medium is any one or a mixture of natural sand, artificial sand and slag. The infiltration medium is added into the soil layer 12, so that the infiltration rate of rainfall entering the soil is improved, and water entering the soil bypasses most of soil matrix, and the response speed of underground water is accelerated.
