Technical Field

The utility model belongs to the technical field of the rainwater collection technique and specifically relates to a system of recycling is collected to building roofing rainwater.

Background

A building roof rainwater collecting system is a technology for collecting roof rainwater and utilizing the collected rainwater after simple precipitation and filtration treatment. The treated rainwater can be used as reclaimed water, such as flushing a toilet, irrigating greenbelts or spraying on a road surface, so that the rainwater can be recycled. To the area that the water resource is relatively scarce, can increase usable water resource volume, alleviate the lack of water situation, reduce the confluence of rainwater and sewage simultaneously to reduce sewage treatment's pressure and burden.

The Chinese patent with publication number CN201720033556.X discloses a rainwater recycling and comprehensive utilization structure, which comprises an underground reservoir arranged on the outer side of a building foundation, a water collecting tank arranged on the roof of the building, a rainwater purification system and a rainwater collecting tank; a sewage filter plate, a reservoir cover plate and a water pumping pit are arranged in the underground reservoir; rainwater collected by a building roof enters an underground reservoir through a rainwater collecting tank and a building rainwater pipe, ground rainwater is collected into the underground reservoir through a reservoir cover plate, redundant rainwater in the underground reservoir is discharged to a municipal pipe network through a municipal pipeline connecting pipe, and a one-way water stop valve is arranged at the joint of the municipal pipeline connecting pipe and the municipal pipeline; the rainwater purification system is arranged at the bottom of the water collection tank, rainwater in the water collection tank passes through the rainwater purification system and then is used for flushing toilets in the building, the water storage tank cover plate is made of reinforced concrete materials, the thickness of the water storage tank cover plate is 100mm, the width of the water storage tank cover plate is 3m, and the water storage tank cover plate is arranged along the top of the underground water storage tank.

Although the rainwater recycling comprehensive utilization structure can recycle rainwater. However, as the building roof usually has sundries such as sandy soil, plastic bags and the like which are easy to be blown up by wind, the sundries on the building roof can be washed into the underground water storage tank by rainwater after raining, the sundries with the particle size smaller than that of the sewage filter plate can be deposited at the bottom of the underground water storage tank, and when the sundries at the bottom of the underground water storage tank are too much, the municipal pipeline connecting pipe and the rear water pumping pipe connecting pipe are easy to be blocked; the impurities with the particle size larger than that of the dirt filtering plate can be accumulated on the dirt filtering plate, the water permeability of the dirt filtering plate is weakened, rainwater easily overflows from a gap of the water storage tank cover plate when heavy rain falls, and the water storage tank cover plate can be jacked up when the rain falls seriously; therefore, the user needs to clean out the sundries in the underground water reservoir to ensure the performance of the underground water reservoir.
