specific Embodiment approach 1

[0008] Specific implementation mode one: combine figure 1 In this embodiment, a double-layer subsurface flow artificial wetland landscape pool has a specific structure as follows:

[0009] The double-layer submerged flow artificial wetland landscape pool consists of landscape pool 1, upper horizontal subsurface flow 2, partition layer 3, lower horizontal subsurface flow 4, foundation layer 5, water intake adjustment pool 6, joint pool 7, submersible pump 8, circulating water pipe 9, The drain pipe 10, the left water isolation valve 12, the right water isolation valve 13, the left filter wall 14, the right filter wall 15 and the metal grille 16 are composed. The landscape pool 1 is set on the upper horizontal undercurrent 2, and the upper horizontal undercurrent 2 is laid Above the plate layer 3, a lower horizontal underflow 4 is provided between the partition layer 3 and the foundation layer 5, and an inflow regulating pool 6 is provided on one side of the landscape pool 1, th...

specific Embodiment approach 2

[0016] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the landscape pool 1 is soil or water. Others are the same as in the first embodiment.

[0017] When the landscape pool 1 of the present embodiment is soil, flowers and plants can be planted in the landscape pool 1; when the landscape pool 1 is water, aquatic plants can be planted in the landscape pool 1, and water landscapes can also be set in the landscape pool 1, such as Water landscapes such as fountains, cascading water, water walls, drips, etc.

specific Embodiment approach 3

[0018] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the main preparation materials of the upper horizontal underflow 2 are pebbles, volcanic rocks, and zeolites. Others are the same as in the first or second embodiment.

[0019] In the double-layer subsurface flow artificial wetland landscape pool of this embodiment, the upper horizontal subsurface flow 2 prepared by using pebbles, volcanic rocks, and zeolites as main raw materials can play the role of filtering and supporting.

Abstract

The invention discloses a double-layer undercurrent artificial wetland landscape pond and method thereof for recovering and treating urban roof rainwater, relates to a landscape reservoir and a method thereof for recovering and treating urban rainwater, and aims to solve the problem that the rainwater recovery system cannot meet the requirements of continuously purifying and treating rainwater all the year around in northern cold-region cities. The double-layer undercurrent artificial wetland landscape pond consists of a landscape pond, upper layer horizontal undercurrent, a partition plate layer, lower layer horizontal undercurrent, a foundation layer, a water inlet regulating reservoir, a collection tank, a submersible pump, a circulating pipe, a drain pipe, a left water separation valve, a right water separation valve, a left filter wall, a right filter wall and a metal grille. The method specifically comprises the following steps of: 1, collecting rainwater; 2, coagulating and precipitating; 3, filtering; 4, performing ultraviolet sterilization; 5, injecting into the double-layer undercurrent artificial wetland landscape pond to perform deep processing; and 6, making the treated rainwater for later use. The pond and the method are mainly used for rainwater recovery and recycling and urban beautification of the northern cold-region cities.

Description

technical field [0001] The invention relates to a landscape reservoir and a method for recycling and treating urban rainwater. Background technique [0002] Rainwater recovery and treatment technology has been widely valued under the current trend of urban ecological construction, and various water storage and waterlogging prevention systems have gradually emerged. Waterlogging system and infiltration water storage and flood prevention system. The emergence of water storage and flood prevention systems not only saves water resources, but also beautifies our cities. However, the existing equipment is limited by climatic conditions, and the treatment effect in winter is poor; the occupied area is relatively large, and the unit load is relatively small. Especially in the northern cold region cities, due to the long winter and harsh climate, the existing rainwater recovery and treatment technology can only be operated in three levels of spring, summer and autumn, and cannot me...
