Problems solved by technology

However, none of these filtering devices consider the disposal of soluble pollutants such as nitrogen and phosphorus in the rainwater in the initial stage of roof planting, and the outer diameter is significantly larger than the rainwater downpipe, so they cannot be directly installed on the existing rainwater downpipe

Abstract

The invention provides a rainwater treatment system and method for a planted roof. The system comprises a connecting pipe, a water collecting funnel, a spiral coil pipe, an overflow pipe and a water outlet pipe group. The pipe diameter and the rotation radius of the coil pipe are gradually decreased from top to bottom, so that the water collecting area is increased, impurities such as particles inrainwater are quickly filtered out through reducing and spiral acceleration, water is thrown from the coil pipe into a rainwater pipe to be used, while water with high mud content is led out from water outlet pipes at the bottom end of the coil pipe, and thus the rainwater on the planted roof is subjected to primary drainage and medium filtration. The system can be directly installed in the existing rainwater pipe, can effectively separate particulate suspended matter and pollutants from the rainwater of the planted roof, and avoids blockage of the rainwater pipe and rainwater pollution.

Description

technical field [0001] The invention relates to a planting roof rainwater treatment system and method, and belongs to the technical field of drainage structures for fixed buildings. Background technique [0002] Due to the existence of plants and planting substrates in the roof greening system, its drainage system needs to carry more pollutants than traditional roofs. Especially in the early stage, the erosion of the planting substrate by rainwater leads to the content of nitrogen, phosphorus, sediment and other pollutants in the surface runoff. Higher, it is easy to cause pollution and block the pipe network. [0003] At the same time, for existing buildings, the original rainwater collection and discharge pipelines have limited space and do not have the ability to separate and treat them, and the cost of redesigning and installing a suitable rainwater collection system is too high and the project volume is huge. [0004] After retrieval, the patent document CN207253912U d...
