A system for treating and recycling rainwater, including at least three stages constructed wetlands disposed along a sloped surface. Each stage constructed wetland includes a coarse gravel layer, a fine gravel layer, an improved soil layer, and wetland plants from bottom to top. Slopes are disposed at two sides of the upper part of each constructed wetland and are different in heights. An intermediate overflow pipe is disposed at the top of the slope between every two adjacent constructed wetlands. A last overflow pipe communicates with a municipal rainwater pipe. The coarse gravel layers of every two adjacent constructed wetlands are connected by connecting pipes. A perforated water collecting pipe is disposed at front ends of the connecting pipes. A water outlet pipe is disposed in the bottom of the coarse gravel layer of a last stage constructed wetland and is connected to a clean water reservoir.

System for treating and recycling rainwater

A system for harvesting rainwater for use in a skirt building. The skirt building includes a main building and a podium supporting the main building. The system includes: a standpipe; a buffer channel; a filter channel; and a green roof. The green roof includes a vegetation region including a baffled diversion corridor, and a bottom filtering layer including a drainage pipe. The standpipe is arranged on the main building and is connected to the buffer channel where the energy of rainwater flowing out of the standpipe is dissipated. The buffer channel, the filter channel, and the green roof are arranged on the podium, and the buffer channel communicates with the filter channel. The filter channel is connected to the green roof. The filter channel is divided into a plurality of sections respectively filled with different matrix materials.
