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 planting roofs. The system includes a connecting pipe, a water collection funnel, a spiral coil pipe, an overflow pipe and a water outlet pipe group. Large catchment area, variable diameter and spiral acceleration are used to quickly filter out impurities such as particles in the rainwater, and the water is thrown from the coil to the rainwater pipe for use, while the water with high mud content is drawn from the outlet pipe at the bottom of the coil, which is beneficial to planting The rainwater on the roof is discarded at the initial stage and filtered in the middle stage. The invention can be directly installed in the existing rainwater pipes, can effectively separate suspended particles and pollutants in the rainwater of planting roofs, and avoid blockage of rainwater pipes 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...
