Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment provides a comprehensive control method for rainwater in a sponge city, as shown in fig. 1, including:
the rainwater collecting module is used for collecting rainwater;
the water control and pollution elimination module is used for filtering the collected rainwater;
the drainage module is used for storing and transferring the collected rainwater or the filtered rainwater;
and the water using module is used for using the water from the drainage module or the water control and sewage elimination module.
The comprehensive control method for the sponge urban rainwater mainly comprises the steps of purifying the rainwater and transferring the purified rainwater to a municipal water system.
Specifically, the water permeable device is arranged on a lane, a non-lane, a square and the like, rainwater passing through the water permeable device is transferred to systems such as a bioretention grass ditch, a green land, bioretention facilities, a rainwater garden, a grass planting ditch and the like by means of hidden culverts and the like, and is collected into a rainwater canal through an open blind pipe after being purified by plant roots, soil and the like. The rainwater pipe canal stores the collected purified rainwater, or directly supplies landscape water for greening irrigation.
The technical scheme in the embodiment is further optimized: rainwater collected in the rainwater collection module can directly enter the drainage module.
When the precipitation is too large and exceeds the bearing capacity of the water control and pollution elimination module, part of rainwater cannot be treated by the water control and pollution elimination module and is directly discharged into the water using module.
The technical scheme in the embodiment is further optimized, and the rainwater collection module collects rainwater from road bridges and park greenbelts.
The pollution sources of rainwater in cities are complex, wherein the rainwater pollution sources of road bridges and green places of parks are relatively single, and the arrangement of the water control and sewage elimination modules at the periphery of the water control and sewage elimination modules is convenient.
The technical scheme in the embodiment is further optimized, and the water control and decontamination module comprises one or more of an ecological tree pool, a bioretention grass ditch, a green land, a bioretention facility, a rainwater garden and a grass planting ditch.
The water control decontamination module mainly utilizes soil to filter particles, impurities and some soluble components mixed in the rainwater, and landscape plants can purify the soil simultaneously, so that the rainwater can be purified, and the energy consumption and the influence on the environment of purifying the rainwater in a traditional mode are reduced.
The technical scheme in the embodiment is further optimized, and the system further comprises an waterlogging prevention and control module, wherein the waterlogging prevention and control module is used for directly collecting the overloaded part of rainwater in the water control and decontamination module in the drainage module.
When the precipitation is too large and exceeds the bearing capacity of the water control and pollution elimination module, part of rainwater cannot be treated by the water control and pollution elimination module and is directly discharged into the water utilization module, so that the possibility of flood disasters on the ground surface is reduced.
The technical scheme in the embodiment is further optimized, and the water supply system further comprises an overflow module, wherein the overflow module is used for transferring overflow in the water using module to the drainage module.
Further optimizing the technical scheme in the embodiment, the drainage module comprises:
the storage modules are more than two and used for storing rainwater with different cleanliness;
a transfer module: the rainwater storage module is used for storing rainwater;
and the detection module is used for detecting the water quality in the transfer module and conveying the rainwater with different cleanliness degrees to different storage modules according to the detection result.
The storage modules can comprise any facility capable of storing water, such as a drought stream, a flood discharge channel, a sky river and the like, and when the storage modules are applied specifically, water with different cleanliness can be stored in different storage modules.
The technical scheme in the embodiment is further optimized, the transfer module comprises a header pipe and branch pipes, each branch pipe is correspondingly provided with a storage module, the detection module is arranged on the header pipe, the detection module is connected with electromagnetic valves through a controller, and the electromagnetic valves are in one-to-one correspondence with the branch pipes.
After rainwater enters the main pipe through the opening blind hole after being filtered, the detection module arranged on the main pipe can monitor the cleanliness of the water body in the main pipe, then the detection data is transmitted to the controller, the controller matches the water body with the corresponding storage module, and then the electromagnetic valve on the branch pipe between the storage module and the main pipe is opened.
This structure can avoid when the precipitation is too big, and the rainwater that does not purify is deposited with the water mixture through purifying, leads to whole water white purification.
The technical scheme in the embodiment is further optimized, the water using module comprises more than two sub-modules with different requirements on water quality, and the sub-modules are connected with the designated storage module.
Landscape water, greening irrigation and other municipal water have different requirements on the cleanliness of water bodies, so that the landscape water, the greening irrigation and other municipal water can be treated differently.
Although the invention has been described herein with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More specifically, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, other uses will also be apparent to those skilled in the art.
