Embodiment 1

[0044] like Figure 1-2 As shown, a roof garden divides the roof into four independent roof garden subunits 1 with the same area. The upper part of the subunit 1 is the planting layer 5 and the lower part is the water storage layer 7. In the planting layer 5, there are Vegetation, between every two adjacent sub-units 1, there is a drainage shallow ditch 9 connected to the rainwater pipe 4 on the roof, and the bottom of the water storage layer 7 of each sub-unit 1 is laid 2- 3 drainage pipes 2, each drainage pipe 2 is bent upward at the position close to the shallow drainage ditch 9 until the outlet height of the vertical pipe 21 is equal to the height of the aquifer 7, and the vertical pipe 21 is bent and extended to the 9 shallow drainage ditch To make the drainage pipe 2 communicate with the shallow drainage ditch 9, the drainage pipe 2 at the bottom is provided with a drainage flow hole 22 and wrap the drainage pipe 2 at the bottom with a permeable geotextile, so that the r...

Abstract

The invention relate to a method for strengthening ecological removal of runoff pollution in a roof garden and the roof garden. The roof is divided into a plurality of independent sub-units, and rainwater is independently subjected to sequential aerobic-anoxic/anaerobic purification treatment and stored in each sub-unit; a shallow drainage ditch connected with a house rainwater down pipe is arranged between the adjacent sub-units, and water inlets are formed in each sub-unit, drainage pipes at bottoms of the sub-units are communicated with the shallow drainage ditches, so that excess rain is discharged into the rainwater down pipes in case of great rainfall; the water outlet height of the drainage pipes is equal to the height of a water storage layer positioned at lower parts of the sub-units so as to ensure that the water level of the water storage layer provides water for vegetation in the roof garden. The problems of the roof garden in the prior art that water retention and water holding capacity is poor, frequent watering maintenance is required, purification effect is unsatisfactory and a large amount of roof rainwater loss are solved.

Description

technical field [0001] The invention relates to a method and structure for removing runoff pollution, in particular to a roof garden enhanced ecological method for removing runoff pollution and a roof garden, which belong to the technical field of sponge city construction. Background technique [0002] When the rainy season comes, urban waterlogging brings a lot of inconvenience to the lives of citizens, and even the loss of life and property. It is an urgent problem faced by many cities across the country; With the runoff of rainwater, it is discharged into the urban water body through the municipal pipe network, seriously damaging the urban water environment. In response to the above problems, the state has proposed a brand-new urban construction concept of sponge city. The sponge city requires the city to have the functions of infiltration, stagnation, storage, purification, utilization and drainage of rainwater. [0003] The roof is an important part of the impermeable...
