Sponge roof rainwater collection recycling system

Abstract

The invention discloses a sponge roof rainwater collection recycling system. The sponge roof rainwater collection recycling system includes a rainwater collection unit, a processing unit, and a wateruse terminal; the collection unit includes siphoning type rainwater hoppers which are arranged on a roof at intervals, connection pipes which are arranged vertically and connected to the rainwater hoppers, a suspension pipe which is arranged horizontally and communicates with a lower end of each connection pipe, a vertical pipe which is arranged vertically and communicates with an outer end of thesuspension pipe, and a drainage pipe which is arranged on a ground surface at an angle and communicates with a lower end of the vertical pipe, wherein the drainage pipe guides water to a rainwater inspection well; the processing unit includes a water storage settling pond, a cleaning processing pond, and a recycling water pond which are connected adjacently; and the water use terminal is connected to the recycling water pond through a water use pipe. The roof rainwater collection recycling system can save energy and reduce emission, is environment-friendly, can reduce rainwater discharge, canallow emergency use of rainwater, can recycle non-drinking water of life, can save tap water, can reduce the cost of water processing, and facilitates promotion of development of sponge cities.

Description

technical field [0001] The invention belongs to the field of rainwater recovery and reuse, and in particular relates to a rainwater collection and reuse system for a sponge roof. 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 construc...

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.
