Problems solved by technology

However, the construction methods of related products in our country have the following deficiencies: ① Lack of mass production, simple construction, universal and easy to implement, and widely used module construction methods
② Lack of water storage and purification functions
③ It is difficult to replace the filler, and the adjustment and adaptability are not strong enough
④ Poor interaction with the surface, lack of storable and permeable selection functions
⑤ Lack of available water functions
[0004] The above technologies have a great impact on how to make the storage system adopt two modes of storing water or interacting with the ground for use on non-hardened ground, and control it according to the soil type and permeability of the area to alleviate the peak and diameter of the rainfall period. flow, no specific guidelines were given

Embodiment 1

[0022] Embodiment 1: as figure 1 , figure 2 , image 3 , Figure 4 As shown, the first embodiment of the present invention (interactive wet deposition purification and storage system) has a box body 1, and the box body 1 has a bottom wall (bottom surface, bottom) and four side walls, and is characterized in that the The bottom wall of the casing has a water outlet, and the water outlet 103 is formed by the edge plate 104 that is positioned at the bottom of the box around the bottom wall of the box. The water outlet 103 is a rectangle (cuboid shape), and the area of ​​the water outlet 103 is 90% (or 85%) of the area of ​​the bottom end of the box body 1 . The bottom area of ​​the box 1 (or the bottom area of ​​the box) refers to the total area of ​​the bottom of the box, which can also be said to be the area formed by the bottom wall of the box (when no drain is set) area. The water outlet 103 is provided with an opening and closing control component 3 that enables the ta...

Embodiment 2

[0024] Embodiment 2: as Figure 5 shown, refer to figure 1 , Figure 4 , the second embodiment of the present invention (interactive wet deposition purification and storage system) is similar to the first embodiment. In this embodiment, the preferred filling material 703 is fly ash, sandy loam, perlite, peat soil, sawdust , the combination of vermiculite, the weight ratio of each component is: fly ash: sandy loam: perlite: peat soil: sawdust: vermiculite=0.5:1:0.1:1:0.5:0.2. The difference is that the filling material 703 can also be a combination of peat soil, sawdust and vermiculite, and the weight ratio of the combination can be arbitrary. The biofilm filler 502 is a polyurethane biofiller, which can be placed in the cavity of the second sub-casing 501 . Before use, the filler is artificially bio-filmed to domesticate and cultivate a suitable microbial community, so that the bacterial micelles can attach and renew on the surface of the filler to form a stable biofilm.

Embodiment 3

[0025] Embodiment 3: as Image 6 shown, refer to figure 1 , Figure 4 , the third embodiment of the present invention (interactive wet sedimentation purification regulation and storage system) is similar to the first embodiment. In this embodiment, the preferred filling material 703 is fly ash, sandy loam, perlite, peat soil, sawdust , the combination of vermiculite, the weight ratio of each component is: fly ash: sandy loam: perlite: peat soil: sawdust: vermiculite=0.5:1:0.1:1:0.5:0.2. The difference is that the filling material 703 can also be a combination of fly ash and sandy loam, and the weight ratio of the combination can be arbitrary. The biofilm filler 502 is a polypropylene spherical suspension filler, which can be placed in the cavity of the second sub-casing 501 . Before use, the filler is artificially bio-filmed to domesticate and cultivate a suitable microbial community, so that the bacterial micelles can attach and renew on the surface of the filler to form a...

Abstract

An interactive wet-deposition purification regulation and storage system is provided with a box, a drain outlet is formed in the bottom wall of the box and is formed by edge plates which form the bottom wall of the box and are located on the periphery of the bottom end of the box, and an opening and closing control assembly enabling the box to store water or be in mutual permeation with the ground is arranged on the drain outlet; a retention decomposition layer, a filtration layer, a matrix layer, a fixed layer and a plant stem leaf layer which are supported by the edge plates are sequentially arranged in a cavity of the box in a stacked mode from bottom to top. A header tank is formed between the bottom wall and the four side walls of the box and the outer side wall of a second auxiliary box and is communicated with a cavity of the second auxiliary box. The two modes of storing the water or being in mutual permeation with the ground are adopted, the system is used for a non-harden ground, control is conducted according to the soil type and the permeability of the region where the system is located, the peak value and the runoff volume of the rainfall duration are reduced, and the system has the effects of water purification and storage; the regulation and storage system can be produced in a standardized and modularized mode on a large scale, and is convenient to construct and maintain.

Description

technical field [0001] The invention relates to a rainwater retention, purification, regulation and storage system, in particular to an interactive wet deposition purification, regulation and storage system, which is used on non-hardened ground. Background technique [0002] With the development of society and economy, the process of urbanization is accelerating, and urban line source and non-point source pollution are serious. Urban rainstorm runoff is one of the important sources of urban water pollution and soil pollution. The increase of impermeable ground in the city and the limitation of the drainage capacity of underground waterway pipes make it more difficult to control and treat pollutants. The main way to control the entry of pollutants into soil and groundwater is to intercept and treat pollutants in time. Due to the occurrence of heavy or continuous precipitation, insufficient drainage capacity in some areas is likely to cause urban waterlogging. Moreover, due ...
