Embodiment 1

[0030] Such as figure 1 As shown, the rainwater treatment and storage system that can be used in the sponge city includes a control system, a drainage ditch 1, a buffer pool 2, a coarse filtration pool 3, a fine filtration pool 4, and a storage pool 5 that are sequentially connected. The drainage ditch 1 is set in On both sides of the road, it can simply improve the drainage ditches 1 on both sides of the road so as to realize the coarse filtering effect.

[0031] In order to achieve the filtering effect of the drainage ditch 1, its structure can be improved in the following ways. Specifically, the drainage ditch 1 includes a wall made of resin concrete and a plurality of walls installed at equal intervals on the top to collect the rainwater on the road to the drainage channel. The rainwater grate 13 in the ditch 1 is hung on the top of the drainage ditch 1 with a pair of frame-shaped filter gratings 14 for filtering the rainwater collected by the rainwater grate 13, and its l...

Embodiment 2

[0045] This embodiment is a further improvement made to the rainwater treatment and storage system on the basis of Embodiment 1. For details, refer to figure 1 and figure 2 , the rainwater treatment and storage system that can be used in the sponge city also includes a backwashing device 7 for cleaning the coarse filter tank 3 and the fine filter tank 4 .

[0046] During implementation, the preferred backwashing device 7 of the present embodiment includes a water inlet pipe 71 extending to the bottom of the reservoir 5, a water pump 72 installed on the top of the reservoir 5 and connected to the control unit and the water inlet pipe 71, respectively connected to the coarse filter. Pool 3, fine filter pool 4 and the backwash pipe 73 that connects with water pump 72 and the blowdown pipe 33 that the sewage of cleaning coarse filter pool 3 and fine filter pool 4 are discharged in the soil that the rough filter pool 3 bottoms are installed, coarse filter pool 3 and the bottom en...

Embodiment 3

[0049] This embodiment is a further improvement made to the coarse filter pool 3 and the fine filter pool 4 on the basis of embodiment 2, specifically refer to figure 2 , the bottom of the coarse filter tank 3 is provided with a silt collection boss 32 and a silt collection tank, the bottom of the fine filter tank 4 is provided with a mud collection boss 41 and a mud collection tank; the sewage pipe 33 is installed at the place of the silt collection tank , The mud discharge pipe 34 conducts with the mud collection tank and the silt collection tank.

[0050] The top surface of silt collection boss 32 and mud collection boss 41 is an inclined slope, and the direction of inclination of the two is all toward respective silt collection tank and mud collection tank, after setting like this, can be to silt and mud It plays a certain diversion effect, so that the sediment is collected in the sediment collection tank, and the mud is collected in the mud collection tank, which is conv...

Abstract

The invention discloses a rainwater treatment and storage system capable of being applied to sponge cities. A filtering grating is arranged on the top of a drainage ditch, and the lower end of the filtering grating is communicated with an artificial wetland area; the artificial humid area comprises a rainwater retention area and a wetland enclosing wall arranged on the edge of the rainwater retention area, and a permeable geotechnical cloth is arranged on the outer surface of the bottom face of the rainwater retention area; a buffer pool is communicated with a rough filtration pool through a flow guiding pipe, and a drainage pipe communicated with the rainwater retention area is connected to the flow guiding pipe; an overflow pipe connected with a municipal rainwater pipe network is arranged at the upper end of a reservoir, the reservoir comprises an inner side wall and an outer side wall, and a sandwich layer communicated with a water storage cavity of the reservoir is formed between the inner side wall and the outer side wall; multiple drainage holes communicated with the sandwich layer are evenly formed in the outer side wall, and the outer side wall is wrapped in the permeable geotechnical cloth; a control system comprises a control unit, an electromagnetic valve, a turbidity sensor, a liquid level sensor and a humidity sensor, and the humidity sensor, the liquid level sensor and the electromagnetic valve are all connected with the control unit.

Description

technical field [0001] The invention relates to the technical field of rainwater recovery and utilization, in particular to a rainwater treatment and storage system that can be used in sponge cities. Background technique [0002] With the significant acceleration of the urbanization process in our country, the continuous expansion of the city scale, the intensification of the urban ground hardening, resulting in the increase of the rainwater runoff coefficient and the acceleration of the confluence, in case of heavy rain, the road surface is prone to water accumulation, and in severe cases, it is easy to cause urban road traffic paralysis and casualties. [0003] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. use. In recent years, with the frequent occurrence of extreme weather, waterlogging is common in many cities in my country after heavy rainfall. The concept of...
