Technical Field

The application relates to the technical field of rainwater infiltration, in particular to a rainwater infiltration pond.

Background

With the rapid industrialization and urbanization development of China, the amount of pollutants from different pollution sources such as cities, industry and agriculture is obviously increased, a large amount of pollutants such as organic matters, nitrogen, phosphorus, toxic substances and the like can enter rivers through various non-point sources such as rainwater runoff and atmospheric settlement, surface source pollution is caused, the rivers are polluted, the functions and the water ecological balance of the rivers are destroyed, and the shortage of water resources is aggravated.

The river surface source pollution reduction method mainly comprises the following steps: rainwater runoff interception, accumulation and purification, permeable pavement, buffer zone technology, ecological bank protection, riverbank zone wetland, pond, land and other purification technologies. The urban river banks are mainly hard revetments and short slope types, so that the problem of limited land is solved, the non-point source pollution control technology under the condition is urgently to be established, the problem of land occupation of urban water environment control measures is solved, and different river-entering pollutant reducing functions are considered. At present, the rainwater purification treatment mode has a good effect, for example, Chinese patent with publication number CN101982622A discloses a rainfall runoff quality-divided collecting and purifying system, in the patent, rainwater directly enters a percolation pool from the upper surface of one side and flows out from the lower part of the other side after converging through a Fengzi ditch, but the problem of low utilization rate of filter materials of a filler layer exists under the condition of light rainfall.

SUMMERY OF THE UTILITY MODEL

The embodiment of the application provides a rainwater seepage flow pond to improve the utilization ratio of packing layer, guarantee the filtration efficiency in seepage flow pond.

The embodiment of the application provides a rainwater seepage pool, which is used for percolating rainwater and comprises a water collecting pipe, a pool body and a filtering area, wherein the water collecting pipe is used for collecting rainwater; the tank body is provided with a water outlet pipe, and the water outlet pipe is used for discharging water in the tank body; the filtering area is arranged in the tank body, the water outlet end of the water collecting pipe is communicated with the filtering area, a packing layer is arranged in the filtering area and used for purifying and filtering the rainwater collected by the water collecting pipe, and the bottom of the filtering area is provided with a flow outlet hole which is used for discharging the rainwater filtered by the packing layer into the tank body; wherein, the water outlet end of the water collecting pipe is connected with a water distribution pipeline which is arranged above the filtering area and is used for dispersing water in the water collecting pipe to flow to the packing layer.

In this scheme, after rainwater in the collector pipe got into the packing layer, the rainwater was percolated downwards by packing layer upper portion gradually at the action of gravity, consequently, set up the water distribution pipeline through the play water end at the collector pipe, the water distribution pipeline can make the packing layer that gets into the filtering area of rainwater dispersibility more in, thereby the utilization ratio of packing layer has been increased, make the filtering area higher to the filtration efficiency of rainwater, purifying effect is better simultaneously, avoid the rainwater to get into in the one point department of packing layer all the time, and make the intraformational packing of packing use very inhomogeneous phenomenon to take place, consequently, the water distribution pipeline can make the rainwater can evenly get into the packing layer, avoid packing layer local load too big, thereby can reduce the condition emergence of short circuit.
