Example Embodiment

[0009] Specific implementation mode one: (see attached figure 1 and figure 2 ) The three-dimensional landscape reservoir system of this embodiment is a three-dimensional landscape reservoir, or is composed of a plurality of series or parallel three-dimensional landscape reservoirs; the three-dimensional landscape reservoir includes reservoir 2 and landscape Pool 1, the landscape medium 4 is housed in the landscape pool 1, the discharge outlet 2-1 is set at the lower end of the side wall of the reservoir 2, the overflow port 2-2 is set at the upper end of the side wall of the reservoir 2, and the The upper part of the side wall is provided with a water inlet 2-3, which is characterized in that the landscape pool 1 is located above the reservoir 2, and the reservoir 2 communicates with the landscape pool 1 through the communication device 3.

[0010] In the three-dimensional landscape storage pool of this embodiment, the upper layer is a flower pond, landscape lawn, aquatic pl...

Example Embodiment

[0011] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the connection pipes with a slope of 2 to 8 degrees are used to connect the reservoirs 2 in the series connection, and the outlet of the connecting pipes of the reservoirs 2 is set at the The middle and lower part of the side wall of the pool. Others are the same as in the first embodiment.

[0012] The three-dimensional landscape storage tank system of this embodiment connects multiple three-dimensional landscape storage tanks in series, and can combine the height of the terrain or the gradient change of the depth of the bottom of the pool to connect the water outlet of the previous storage tank to the next storage tank. The connecting pipe between the water inlets forms a slope, and under the action of the pressure difference formed between the upper reservoir and the last reservoir, the water forms a natural flow state, increases the chance of contact with oxygen, and main...

Example Embodiment

[0013] Specific embodiment 3: The difference between this embodiment and specific embodiment 1 is that the connection pipes with a slope of 5 degrees are used to connect the reservoirs 2 in the series connection, and the outlet of the connecting pipes of the reservoirs 2 is set at the reservoir 2 the middle and lower part of the side wall. Others are the same as in the first embodiment.

Abstract

The invention relates to a three-dimensional landscape impounding reservoir system and a method for recovering urban roofing rainwater by using the same, relating to a landscape impounding reservoir and a method for recovering urban rainwater by using the same. The invention solves the problem of small application range of a traditional comprehensive urban rainwater utilization method. The three-dimensional landscape impounding reservoir system is a three-dimensional landscape impounding reservoir or is formed by connecting a plurality of three-dimensional landscape impounding reservoirs in series or parallel; each three-dimensional landscape impounding reservoir comprises an impounding reservoir and a landscape reservoir, and a drain hole, an overflowing hole and a water inlet are arranged at the side wall of the impounding reservoir which is communicated with the landscape reservoir through a communication device. The method comprises the following steps of: collecting rainwater to a high-density sedimentation tank for coagulation; then, filtering with a V-shaped filter tank and sterilizing with ultraviolet rays; and entering the three-dimensional landscape impounding reservoir system to finish the recovery of the urban roofing rainwater. The invention combines the rainwater recovery and the landscape by fully utilizing the urban space and can be used as an independent rainwater recovery and urban waterlogging prevention system or as an externally-hung circulating unit of a drainage system.

Description

Technical field: [0001] The invention relates to a landscape storage tank and a method for recycling urban rainwater using the same. Background technique: [0002] Under the current trend of urban ecological construction, rainwater recovery and utilization technology has been widely valued. There are two existing methods for comprehensive utilization of urban rainwater: 1. Deconcentrating water storage and anti-flooding system, which is composed of small pipes all over the courtyard, open channels running through the linear park landscape, and closed sedimentation tanks. This method is only suitable for areas with moderate rainfall, uniform rainfall and small cities; second, to set up large flood storage tanks underground to collect and store rainwater. It has dual effects of flood detention and rainwater storage, but in large cities with little available space, the application of large flood storage tanks is limited, and this method is only applicable to areas with small c...
