[0042] As Figure 1 As shown in the drawings, the embodiment of the present application provides a sponge city high-elevation rainwater management method, comprising:

[0043] Step S101, obtain the historical rainfall distribution and pollution index of the target area, establish a ladder type storage facility according to the historical rainfall distribution, and set the filter material of the ladder type storage facility based on the pollution index.

[0044] Specifically, for high-elevation target areas that need to be managed for rainfall resources, such as areas along highways, railways, and around large dikes, meteorological big data from meteorological service structures such as local weather stations in the target area is obtained. Then, the annual average rainfall, monthly average rainfall, and frequency of extreme rainfall events are calculated by statistical analysis software to perform rainfall statistics for the target area. For the target area, rainfall distribution statistics can also be performed, i.e., the rainfall data in high-elevation areas to low-elevation areas may not be the same, and there is a difference in rainfall, which needs to be counted separately. Secondly, the pollution index of the target area is obtained, which can include pollutants on the road surface, such as oil stains, heavy metals, rubber particles, etc. According to the historical rainfall, corresponding ladder-type storage facilities can be established, wherein the ladder-type storage facilities are combined with the topographic features, and the storage facilities near the main drainage path are selected to maximize their rainwater collection effect. The capacity planning of the ladder-type storage facilities should be based on rainfall distribution to estimate the minimum capacity required for each storage facility corresponding to different elevations to ensure that more than 95% of rainfall events can be handled without overflow. After determining the ladder-type storage facilities, the connections between the storage facilities at different elevations should be connected by filtering materials, and the rainwater is filtered by each level of storage facility. For example, if the ladder-type storage facility includes four levels of storage facilities, the connection between the highest level of storage facility and the second level of storage facility can be primary filtering, such as using gravel, coarse sand, etc. physical filtering materials to remove large-sized solid waste; the connection between the second level of storage facility and the third level of storage facility can be intermediate filtering, such as using activated carbon, biochar, etc. high-efficiency adsorption materials to treat organic pollutants; the connection between the third level of storage facility and the lowest level of storage facility can be high-level filtering, such as selecting professional filtering media for specific pollutants, such as equipping zeolite and zero-valent iron particles when heavy metal pollution is frequent in the target area, or using activated carbon and biochar for filtering when oil stains or organic matter pollution is more common in the target area.

[0045] In addition, for different elevations of the target area, the corresponding main pollutants may also be different, so the pollutant concentration distribution of different elevations can be obtained to determine the main pollutants corresponding to different elevations, and the filtering materials of the storage facilities corresponding to the elevations are set based on the main pollutants.

[0046] Step S102, obtaining real-time rainfall of the target area, and comparing the real-time rainfall with the elevation map to generate a corresponding rainfall elevation map.

[0047] Specifically, when it is detected that the target area has rainfall, the real-time rainfall of the target area is obtained through an automatic weather station network, a mobile weather radar, or satellite remote sensing data, etc. The real-time rainfall includes the hourly rainfall of the target area, future rainfall trends, etc. Then, a topographic map of the target area is obtained, which includes different topographic distributions corresponding to the stepped storage and detention facilities in the target area, and natural and artificial features can also be labeled, such as roads, buildings, green spaces, wetlands, etc., so as to better understand the impact of rainfall on these elements. Then, the real-time rainfall and the topographic map are superimposed and analyzed, such as superimposing the rainfall distribution layer obtained by interpolation and the DEM topographic layer in the GIS software to generate a rainfall topographic map that comprehensively reflects the relationship between rainfall intensity and topographic relief. According to needs, auxiliary elements such as isohyets, water flow direction arrows, etc. can be added to the map to help visually display how the rainfall flows with the change of topography.

[0048] In step S103, the initial water level of the stepped storage and detention facility is obtained, a topographic water level model is established in combination with the rainfall topographic map, and the pumping rate and the water release rate of the stepped storage and detention facility are adjusted based on the topographic water level model, so that the water level of the stepped storage and detention facility is maintained within a preset range.

[0049] Specifically, the initial water level of each storage and retention facility collected by the detection device is obtained, the generated rainfall topography map is combined with the specific location and capacity parameters of the storage and retention facility, and a three-dimensional model is created in a GIS environment, wherein the three-dimensional model should further consider the influence of factors such as terrain, soil permeability, groundwater flow, etc. on the storage and retention facility. Then the water flow path is simulated, such as predicting the natural flow direction of water after rainfall by using a digital elevation model (DEM), and determining which areas are most likely to drain to a specific storage and retention facility, so as to determine the future water level of the storage and retention facility. In addition, each storage and retention facility has a corresponding ideal water level interval, i.e. a preset range, and when the water level of the storage and retention facility exceeds the preset range, there may be a risk of flooding. In order to keep the water level of the stepped storage and retention facility within the preset range, the stepped storage and retention facility is dynamically adjusted, and generally speaking, the higher the terrain, the more conservative the data setting of the preset range. Dynamic adjustment can dynamically adjust the water inflow and outflow of the stepped storage and retention facility according to real-time rainfall conditions, the autonomous drainage capacity corresponding to each terrain, future water level prediction, and the lateral comparison of the water level of the stepped storage and retention facility. The specific adjustment method can be, for example, when the main rainfall area is determined based on the rainfall topography map, wherein the main rainfall area is the storage and retention facility most likely to have a flooding situation. When the main rainfall area is a high-terrain storage and retention facility, the estimated water level map output by the terrain water level model is combined to dynamically adjust the water release rate of the stepped storage and retention facility, so as to keep each terrain corresponding storage and retention facility within the preset range as much as possible; when the main rainfall area is a low-terrain storage and retention facility, the estimated water level map output by the terrain water level model is combined to dynamically adjust the water release rate of the stepped storage and retention facility and the water pumping rate of the high-terrain storage and retention facility, so that the storage and retention facility can simultaneously adjust the water level to the high-terrain and low-terrain storage and retention facilities.

[0050] In step S104, the drainage demand corresponding to different terrains is obtained, the water quality requirement of the corresponding terrain is determined based on the drainage demand, the water level of the stepped storage and retention facility is monitored in real time, and it is judged whether the water level is kept within the preset range and whether the water quality meets the water quality requirement of the corresponding terrain.

[0051] Specifically, based on the rainfall topography map in the above steps, various topographic features such as elevation, slope, etc. are identified, and the natural drainage capacity and drainage demand of each area are evaluated according to these information, including: analyzing the land use situation (such as agricultural area, industrial area, residential area, etc.) around each area, understanding the influence of potential pollution sources on water body, and determining the water quality requirements of different topography according to the environmental impact. Then by installing liquid level sensor and multi-parameter water quality analysis instrument inside each storage and detention facility, real-time collection of water level and water quality data is realized, and it is judged whether the water level is kept within the preset range and whether the water quality meets the water quality requirements of the corresponding topography, so as to directly judge whether the storage and detention facility meets the water storage and filtration requirements of rainwater. When the judgment result does not meet the water storage and filtration requirements of rainwater, the corresponding alarm step can be triggered, such as when the water level is not within the preset range, based on the topography of the storage and detention facility with water level not within the preset range, the corresponding level of waterlogging alarm level is determined, generally speaking, the higher the topography of the storage and detention facility, the higher the corresponding alarm level when the water level exceeds the expectation. When the water quality does not meet the water quality requirements of the corresponding topography, the filter material alarm of the storage and detention facility corresponding to the upper level is carried out, so that the relevant staff can timely adjust and replace the filter material.

[0052] In addition, near the stepped storage and detention facility, stepped farmland can be designed according to the slope of the topography. The layout of the farmland is combined with the storage and detention facility to guide and slow down the speed of rainwater runoff layer by layer from top to bottom, and to ensure that the area of the farmland is not reduced. Each level of farmland not only plays a cultivation function, but also can reduce the impact of flood on farmland by reasonably guiding runoff, and improve the stability of agricultural production.

[0053] The sponge city high-elevation rainwater management method provided by the embodiment of the present application acquires the historical rainfall distribution and pollution index of a target area, establishes a stepped storage and detention facility according to the historical rainfall distribution, and sets filter materials of the stepped storage and detention facility based on the pollution index; acquires real-time rainfall of the target area, compares the real-time rainfall with a topography map, and generates a corresponding rainfall topography map; acquires an initial water level of the stepped storage and detention facility, establishes a topographic water level model in combination with the rainfall topography map, adjusts pumping rate and water releasing rate of the stepped storage and detention facility based on the topographic water level model, so that the water level of the stepped storage and detention facility is kept within a preset range; acquires drainage demand corresponding to different topography, determines water quality requirements of corresponding topography based on the drainage demand, and monitors the water level and water quality of the stepped storage and detention facility in real time, judges whether the water level is kept within the preset range and whether the water quality meets the water quality requirements of the corresponding topography. In this way, the flood can be effectively detained and stored during heavy rain, soil erosion can be prevented, pollutants in rainwater can be removed through multi-stage purification means, water quality can be improved, and recycling of rainwater resources can be realized.
