Municipal rainwater collecting system

Abstract

The invention relates to the technical field of municipal rainwater utilization, and discloses a municipal rainwater collecting system. The municipal rainwater collecting system comprises a roof rainwater collecting pipe, a ground rainwater collecting pool, an underground water storage tank, a plant irrigation pipe and a toilet pipe; a treatment tank is arranged between the underground water storage tank and the plant irrigation pipe, treatment plates are arranged inside the treatment tank, zeolite molecular sieve particles are detachably connected to the treatment plates, and a heavy metal detector is arranged at one end, near the plant irrigation pipe, of the treatment tank. The municipal rainwater collecting system has the advantages that heavy metal ions can be adsorbed from sewage since the zeolite molecular sieve particles have ion exchange and adsorption properties; when water passes through the treatment plates, heavy metals in the water can be absorbed by the zeolite molecularsieve particles on the treatment plates to ultimately reduce the possibility of the heavy metals existing in rainwater for irrigating plants.

Description

technical field [0001] The invention relates to the technical field of municipal rainwater utilization, in particular to a municipal rainwater collection system. Background technique [0002] With the gradual improvement of modern material living standards, the waste of water resources is becoming more and more serious. Both urban water use and domestic water use are accelerating the loss of water resources. [0003] At present, the announcement number is CN203625966U, and the announcement date is June 4, 2014. The Chinese patent discloses a rainwater collection and reuse system, including roof rainwater collection pipes, ground rainwater collection pools, roof rainwater collection pipes, and ground rainwater collection pools. The rainwater in the underground storage pool is collected in the underground storage tank, and the rainwater in the underground storage tank is pumped to the roof storage tank through the pump. The rainwater in the roof storage tank is connected to th...

Problems solved by technology

[0004] This kind of rainwater collection and reuse system uses the rainwater collected from the roof rainwater collection pipe and the ground rainwater collection tank to collect in the underground storage tank, and then the water in the underground storage tank can be used for toilet toilets and plant irrigation; With the gradual development of the industrial level, the rainwater in some industrial areas may contain some industrial heavy metals, and when the rainwater containing heavy metals is used for plant irrigation, it is likely to cause the plants to wither
