Abstract

The invention discloses a spongy rainwater collecting and recycling system for planting plants, and belongs to the technical field of sponge cities. The spongy rainwater collecting and recycling system for planting plants is provided with a rainwater collecting, utilizing and recycling device, a vegetation layer is arranged on the surface, a fine sand layer is arranged on the lower portion of the vegetation layer, a gravel layer is arranged on the lower portion of the fine sand layer, a first water collecting well is arranged on the lower portion of the gravel layer, and a first water collector and a second water collector are installed in the first water collecting well; the top of the first water collector in the first water collecting well extends out to be connected with an irrigation nozzle on the upper portion of the vegetation layer; and a second water collecting well is arranged on the right side of the vegetation layer, and the vegetation layer and the second water collecting well are connected through a first water inlet pipe. According to the system, rainwater can be effectively collected for secondary utilization, and runoff water can be collected and filtered to be used for watering trees and used as domestic water; and the system is energy-saving and environmentally friendly, the construction is convenient, the rainwater can be effectively collected and utilized, and water resources are saved.

Description

technical field [0001] The invention relates to a rainwater collection and recycling system, in particular to a spongy rainwater collection and recycling system for planting. Background technique [0002] Our country is a large agricultural country, and the planting area of ​​the planting industry ranks among the top in the world. However, in order to increase the output of the planting industry, we often use excessive chemical fertilizers. The nitrogen, phosphorus and other nutrients in the chemical fertilizers will produce abnormal nutrients along with the runoff of the farmland. Point source pollution. Studies have shown that runoff and drainage are the main ways for nitrogen and phosphorus pollution to transfer from farmland to other water bodies. This makes the non-point source pollution load generated by agricultural runoff the main reason for the eutrophication of lakes, rivers and other water bodies and the loss of water ecosystem services. Ecosystems have consider...
