Roof rainwater collecting, storing and recycling system

Abstract

The invention discloses a roof rainwater collecting, storing and recycling system, which comprises a roof rainwater collecting pipe network, a primary filtering system, a primary water using end and a secondary water using end, and further comprises a primary storing tank, a secondary storing tank and an electromagnetic valve control system, wherein water in the primary storing tank can enter the secondary storing tank by virtue of an advanced filtering system; rainwater, which is collected by virtue of the roof rainwater collecting pipe network, is filtered by virtue of the primary filtering system and enters the primary storing tank, and partial rainwater is filtered as required and enters the secondary storing tank; each storing tank independently communicates with a water inlet end of a water pump by virtue of a water delivery pipe, and an electromagnetic valve is arranged on the water delivery pipe; a water outlet end of the water pump communicates with the primary water using end and the secondary water using end; and the electromagnetic valve control system, by controlling the electromagnetic valve, is in charge of turning on the water inlet of the water pump towards the required storing tank. The roof rainwater collecting, storing and recycling system provided by the invention has the beneficial effects that recycled water, at various cleanliness levels, can be automatically supplied to adapt to requirements of different water using environments.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a roof rainwater collection, storage and reuse system. Background technique [0002] Rainwater collection and reuse is conducive to water saving and energy saving, and has broad development prospects. Chinese patent document CN103253816A disclosed "rainwater reuse system and its treatment method" on August 21, 2013. The rainwater reuse system includes a cistern, a filter tank and a clean water pool. The cistern and municipal rainwater pipes The clean water pool is connected to the reuse pipe network, wherein the municipal rainwater pipe network is connected to the water storage tank through the waste flow device, the disinfection device, the primary filter device and the storage tank in sequence. The rainwater reuse system and its treatment method provided by the invention can achieve secondary disinfection and three-stage filtration by setting up a waste flow device, a d...

Problems solved by technology

The general defect of the aforementioned traditional technical solutions is that it can only provide water with one degree of cleanliness, and cannot automatically provide reused water with different degrees of cleanliness according to the needs of water use. If the degree of treatment is low, although the treatment cost can be saved, the scope of water reuse It will be greatly reduced; if the degree of treatment is high, it can cover most of the scope of use, and it will be wasteful in a low-demand water environment, especially the treatment cost in rainwater reuse is not low

Such waste limits the promotion of rainwater harvesting and reuse systems
