Drawings
Fig. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic view of the structure of the rainwater treatment apparatus of the present invention.
Detailed Description
The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.
The underground rainwater collection system shown in fig. 1 comprises an overflow well 2, a hanging basket sewage interception well 3, a rainwater processor 4, a rainwater pool 5, a first connecting water pipe, a second connecting water pipe and a third connecting water pipe which are arranged below an outdoor lawn 12; the water inlet of overflow well 2 and rainwater manifold 1 intercommunication, the delivery port of overflow well 2 pass through first connecting water pipe and hang basket and cut the water inlet intercommunication of dirty well 3, hang basket and cut the water outlet of dirty well 3 and pass through the water inlet intercommunication of second connecting water pipe and rainwater treater 4, and the delivery port of rainwater treater 4 passes through the third connecting water pipe and 5 top intercommunications in rainwater pond.
An overflow pipe is arranged in the overflow well 2, and the overflow pipe is consistent with the first connecting water pipe and the third connecting water pipe in elevation. As shown in fig. 2, the second connecting water pipe is Z-shaped, the water inlet end of the second connecting water pipe is consistent with the elevation of the overflow pipe, the water outlet end of the second connecting water pipe is consistent with the height of the water inlet of the rainwater treatment device 4, the water inlet of the rainwater treatment device 4 is lower than the water outlet, and the water inlet flows to the water outlet through the filter in the rainwater treatment device 4. Rainwater flows into the bottom of the filter from the water inlet, passes through the filter layer of the filter and flows out of the water outlet at the upper end to purify water, and the guarantee fall of the water inlet to the water outlet is guaranteed.
