Roof rainwater treatment system for sponge type residence community

Abstract

The invention provides a roof rainwater treatment system for a sponge type residence community. The roof rainwater treatment system comprises a rainwater vertical pipe, a buffering sand sediment well,a gravel filling layer, a sewage interception layer, a water draining pipe and a rainwater storage pond. A water discharging port of the rainwater vertical pipe is located over the gravel filling layer, and the gravel filling layer is laid at the top end of the interior of the buffering sand sediment well. The sewage interception layer is located below the gravel filling layer. The bottom end ofthe interior of the buffering sand sediment well communicates with the rainwater storage pond through the water draining pipe. Water seeping holes are formed in the side wall of the buffering sand sediment well. By means of the roof rainwater treatment system, the gravel filling layer at the position of the top end of the buffering sand sediment well of the system can be used for conducting energyeliminating on rainwater falling from the rainwater vertical pipe, the scouring influences of the rainwater on the ground are reduced, and in addition, a preliminary filtering effect is achieved. Thesewage interception layer placed on the lower layer is used for conducting secondary filtering on the rainwater entering the buffering sand sediment well, and after the bottom water draining pipe isconnected in the rainwater storage pond for treatment, the rainwater is used for greening irrigation and road flushing.

Description

technical field [0001] The invention belongs to the technical field of roof rainwater treatment, in particular to a roof rainwater treatment system of a sponge-type residential area. Background technique [0002] Roof rainwater disconnection technology is common in sponge-type residential quarters. Most of the current methods are very simple. It is reflected in the situation that the rainwater from the rainwater pipe is directly connected to the surrounding green space. It can be regarded as a "non-design disconnection" or "passive disconnection". ". But this treatment often causes erosion to green spaces and soil. Studies have shown that some high-rise buildings have installed water distribution and energy dissipation measures for the disconnection of roof rainwater, and planted flood-tolerant, non-clustered, and native plants, but still cannot guarantee the stable functionality and safety of the building and the surrounding site , which brings inconvenience to the operat...
