Problems solved by technology

Analysis of the drainage characteristics of the rainwater pumping station in the separate drainage system in Tianjin shows that the rainwater pollution load in the initial stage of rainfall runoff is high and the water quality is poor, and all runoff pollution directly entering the river will form a pollution impact load, resulting in sudden deterioration of the water quality of the urban landscape river in the flood season. Affect the water quality of the receiving water body and destroy the ecological and environmental functions of the water system

Embodiment 1000

[0044] Embodiment Take the embankment length of 1000m as an example to carry out the implementation. The system is installed on the side of the embankment facing the river, and it is arranged in steps along the slope of the embankment.

[0045] see figure 1 and figure 2 , the system is set on the riverside side of the embankment of the river, and a vegetation buffer zone 1 is set up along the slope of the embankment and consistent with the slope of the embankment. Paving cypress, crabgrass or vines are planted on the belt 1; along the slope of the vegetation buffer zone 1, four water collection and diversion belts 2 are arranged according to the length of the vegetation buffer zone 11,000 meters. The downward width of the buffer zone 1 is 0.4m; along the slope of the water collection diversion zone 2, a controllable water storage module 3 is arranged vertically and downwardly, and the controllable water storage module 3 is made of recyclable polypropylene The unit cuboids a...

Abstract

The invention discloses a controllable slow flow pollutant interception circulating module system based on sponge city construction. The system is arranged at the river facing side of a riverbank; a vegetation buffer zone is arranged downwards along the slope of the bank, then, water collecting and guiding zones are arranged downwards, and next, controllable water storage modules are arranged downwards, vertically and correspondingly, wherein each controllable water storage module is of a box structure built by using unit cuboids made of a polypropylene material and is respectively 100-120m long, 1-1.2m wide and 0.5-0.6m deep, and the length and amount of the controllable water storage modules are consistent with those of the water collecting and guiding zones; and the side, close to a river channel, of each controllable water storage module is vertically and downwards provided with a miniature slow flow wetland system which is sequentially provided with a planting soil layer, a packing layer and a supporting layer from top to bottom. The invention embodies a rainy-season runoff pollutant interception control and dry-season landscape water quality maintenance method which provides reference and guide effects for city non-point source pollution control, landscape water quality maintenance, new-built municipal rain discharging hole design and sponge city construction.

Description

technical field [0001] This system belongs to environmental protection engineering and landscape water environment treatment, especially a controllable slow flow circulation module system based on sponge city construction rainwater runoff pollution interception and control facilities in rainy season and landscape water quality maintenance in dry season. Background technique [0002] In the process of rapid urbanization, common problems such as rainwater runoff pollution, flood disasters, and water resource scarcity have become increasingly serious. According to the requirements of sponge city construction, the rainwater management has changed from the traditional "quick drainage" to "seepage, stagnation, storage, purification, use, and drainage" to achieve the purpose of saving water resources and improving the water environment, which is in line with the current ecological civilization advocated , The concept of a resource-saving society is in the same line. [0003] With ...
