Roof rainwater recycling system

Abstract

The invention discloses a roof rainwater recycling system which comprises a rainwater collecting unit, a processing unit and a water use terminal. The collecting unit comprises hydrocone type rainwater hoppers, connection pipes, a suspension pipe, a vertical pipe and a discharge pipe, wherein the hydrocone type rainwater hoppers are arranged on a roof at intervals, the connection pipes are vertically arranged and connected with all the rainwater hoppers, the suspension pipe is horizontally arranged and communicated with the lower end of each connection pipe, the vertical pipe is vertically arranged and communicated with the outer end of the suspension pipe, and the discharge pipe is arranged on the ground in an inclined mode and communicated with the lowered end of the suspension pipe; the discharge pipe leads water into a rainwater inspection well. The processing unit comprises a water storage and sediment pool, a purification and treatment pool and a recycling pool which are adjacent to one another; the water use terminal is connected with the recycling pool through a water use pipe. The roof rainwater recycling system is capable of saving energy and reducing emission, green and environmentally friendly and capable of reducing rainwater emission, and water is available in emergency situations; the roof rainwater recycling system can be further used for non-drinking water in daily life, tap water is saved, the water treatment cost is reduced, and it is beneficial to promote development of a sponge city.

Description

technical field [0001] The invention relates to a system for recycling roof rainwater. Background technique [0002] Sponge city refers to strengthening urban planning and construction management, giving full play to the absorption, storage, infiltration and slow release of rainwater by buildings, roofs, green spaces, water systems and other ecosystems, effectively controlling rainwater runoff, and realizing natural accumulation, natural infiltration, and natural Purified urban development. [0003] When the traditional way of water resource development can no longer increase the water source, recycling rainwater has become an economical and practical way of water resource development. The use of rainwater as a non-traditional resource has multiple functions: saving water and alleviating water crisis. The combination of rainwater harvesting system technology and green space construction will largely change our life, which is full of desperation due to the depletion of wate...

AI Technical Summary

Problems solved by technology

As for rainwater recharge, it has certain practical value in northern cities or cities with excessive groundwater exploitation, but in order to avoid polluting groundwater, the recharge water quality is very high, and the corresponding treatment costs are also very high, so it is rarely used at present

For rainwater reuse, the existing technology is difficult to popularize and apply under the current national conditions. The main reason is that the price of water is low and the cost of treatment engineering is too high, so reuse has no economic value.
