Description
Technical Field
The invention belongs to the technical field of garden engineering, and relates to a residential district rainwater collection and recycling system.
Background
At present, most garden roads have poor water permeability and very limited rainwater absorption and discharge capacity. When the rainfall exceeds the ground absorbing capacity, if underground drainage facilities are lacked, too much rainwater can not be discharged in time, and the garden road is directly submerged by the rainwater, thus seriously hindering people to walk. Meanwhile, the existing garden roads are single, and rainwater cannot be fully utilized, so that most garden roads are paralyzed due to accumulated water when sudden rainstorm or continuous rainfall occurs, and great inconvenience is brought to people.
In order to solve the problem of water accumulation, the residential districts of domestic cities usually collect rainwater and circulating water by using water collection tanks. However, in the process of flowing to the water collecting tank, whether it is raining or water which is not directly absorbed by vegetation, a large amount of leaves and sludge are inevitably brought in, so that rainwater in the water collecting tank is turbid and messy, and meanwhile, a large amount of pollutants and the like are also inevitably brought in by primarily collected rainwater, so that subsequent recycling is difficult to carry out if the rainwater is not treated or is simply settled.
Chinese patent 2017210835730 discloses a rainwater recovery system for residential quarters, comprising: permeable ground: the water diversion device comprises a water permeable brick layer, a filter layer, a first gravel layer, a coarse sand layer, an activated carbon layer and a second gravel layer which are sequentially arranged from top to bottom, wherein a water drainage pipe and a water diversion plate are arranged at the bottom of the second gravel layer, the water drainage pipe is arranged in the middle of the second gravel layer and extends in the front-back direction, the water diversion plate is arranged in a V shape, and the water drainage pipe is positioned in the middle of the water diversion plate; a water collecting tank: the rainwater collecting device is used for collecting rainwater permeating through the permeable ground, and a water inlet of the rainwater collecting device is connected with a drain pipe; a water treatment tank: the top of the water treatment tank is provided with a water treatment clapboard which is suspended above the bottom of the tank and divides the water treatment tank into a water treatment part and a water outlet part, the bottom of the water treatment part is communicated with the water outlet of the water collecting tank, and the top of the water outlet part is communicated with an external landscape water tank. The rainwater recovery system of this patent has certain rainwater recovery ability, but its requirement to collecting the front end is higher, and whole maintenance is comparatively troublesome, and in addition, the purification treatment effect to the circulating water is not good, can only be suitable for the occasion that some requirements are not high.

Then, the entering rainwater is settled in the first tank body 11, under the action of the aeration component 15, the rainwater to be treated is simultaneously subjected to oxygenation treatment, and due to the arrangement of the partition plate 16, "dynamic and static separation" of a water inlet area and a water outlet area in the first tank body 11 is realized, so that impurities such as silt which are newly settled and are flushed from the anti-impact platform 13 through aeration can be settled to the silt accumulation groove 18, and clear water overflows and is discharged through the overflow water outlet 14. In the whole treatment process, due to the arrangement of the anti-impact baffle table 13, the fallen rainwater to be treated cannot impact the silt accumulation groove 18 and the like, so that the back mixing phenomenon is avoided. The oxygen-enriched overflow effluent discharged from the first tank body 11 enters a disinfection and purification tank 2, a certain amount of chlorine dioxide is added for disinfection and purification treatment, and the obtained purified water is discharged into a subsequent water storage tank 3 for standby through a submersible pump.
In the above embodiments or examples, functional components or structures that are not specifically described indicate conventional components or structures that are adopted in the art to achieve the corresponding functions.
The embodiments described above are described to facilitate an understanding and use of the invention by those skilled in the art. It will be readily apparent to those skilled in the art that various modifications to these embodiments may be made, and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty. Therefore, the present invention is not limited to the above embodiments, and those skilled in the art should make improvements and modifications within the scope of the present invention based on the disclosure of the present invention.
