A water outlet 121 is provided on the side of the flocculation area 12, and the water outlet 121 is connected to a water outlet pipe 51, and the other end of the water outlet pipe 51 is exposed from the percolation layer 12 and is connected to a pump 52, and the water outlet end of the pump 52 is connected to the water storage area 11 through a connecting pipe 53, and the water in the flocculation area 12 is pumped into the water storage area 11 through the action of the pump 52, so as to meet the needs of subsequent use. The water storage area 11 is also provided with a water pipe 7 that passes through the cavity top of the water storage area 11 upwards and passes through the percolation layer 2, and water can be taken for use through the water pipe 7.

[0021] The rainwater ecological infiltration purification storage tank in the embodiment integrates the flocculation area for flocculation, multiple infiltration layers for infiltration, and the water storage area for water storage in one tank body, and through reasonable layout, it fully utilizes the vertical space, reduces the floor area of ​​the entire storage tank, and reduces neighborhood land use disputes. It is very suitable for rural ecological construction projects.

[0022] A sludge discharge port 122 is provided at the bottom of the flocculation zone 12, and the sludge discharge port 122 is connected to a sludge discharge pipe 6, the other end of which is exposed in the infiltration layer 2. The sludge discharge pipe 6 can discharge the sludge accumulated and precipitated in the flocculation zone 12 in time through an external sludge extractor.

[0023] When the feeding pipe 4 is specifically arranged, it passes through the cavity bottom and cavity top of the water storage area 11 , and the cavity bottom of the water storage area 11 is in direct sealed contact with the feeding pipe 4 to ensure that the water storage area 11 and the flocculation area 12 are not connected.
