Description
Technical field
The present invention relates to a kind of rainwater treatment device, specifically a kind of early-stage rainwater stream abandoning device.
Background technology
With fast urbanization in current china, cause the steep increasing of water consumption, shortage of water resources phenomenon is increasingly serious, in order to can
Continue the needs of urban development, the recycling of rainwater resource has obtained extensive attention.
The rainwater of early-stage rainwater, i.e. rainfall initial stage.Generally refer to the precipitation that ground 10-15mm thickness has formed rainwash.
Due to rainfall initial stage, rainwater has dissolved the contaminative gas such as a large amount of sour gas in air, vehicle exhaust, industrial waste gas, PM2.5
Body and pollutant, behind ground of landing, and due to washing away roofing, asphalt concrete road etc. so that containing a large amount of in early stage rainwater
Polluter, therefore, substantial amounts of polluter is contained in early-stage rainwater, pollution level is higher, or even dirty beyond ordinary municipal
The pollution level of water.Undressed early-stage rainwater is directly discharged into Storm Sewer Network or river course, and certain journey is caused to water environment
While the pollution of degree, larger pressure can be caused to follow-up rainwater treatment, influence rain water reuse.
CN101487281A discloses a kind of early rainwater automatic flow abandoning apparatus of rainfall control, the rainwater-collecting equipment
Stored including a charge for remittance unit, a water storage unit, one from charge for remittance unit to the rainwater water inlet pipe of water storage unit transportation rainwater, a connection
The rainwater collection collector of water unit and one it is located at abandoned stream pipe between water inlet pipe and collecting pipe, the initial stage of the rainfall control
Rainwater automatic flow abandoning apparatus includes a rainfall gauge, and one is arranged on the electrically operated valve of rainwater-collecting tube inlet, a controller, according to rain
Result of the rainfall compared with default abandoned stream amount measured by gauge, to control the keying of the electrically operated valve of rainwater collection collector,
Early-stage rainwater stream abandoning is automatically controlled so as to realize.The early rainwater automatic flow abandoning apparatus of the rainfall control also includes one
The device of the default abandoned stream amount of regulation, a device for setting not abandoned stream rainfall interval, so as to effectively reduce abandoned stream amount, Yi Jiyi
Level sensor, allow controller and controlled according to the signal of level sensor the water level of water storage unit.The early-stage rainwater is certainly
Dynamic flow abandoning apparatus is complicated, and contained part is more, and production cost height is, it is necessary to which electricity consumption, is unfavorable for promoting the use of on a large scale.
The content of the invention
The technical problems to be solved by the invention are：In view of the shortcomings of the prior art, there is provided one kind is simple in construction, uses the longevity
The early-stage rainwater stream abandoning device that life is long, safety and stability is good, its abandoned stream process to early-stage rainwater is simple, efficient, without
Power supply, energy-saving and environmental protection, really realize runoff pollution control and the maximized purpose of rainwater utilization.
Technical scheme is used by the present invention solves above-mentioned technical problem：A kind of early-stage rainwater stream abandoning device, including abandon
Apparatus main body is flowed, the water collector of the upper and lower opening of back taper is provided with described flow abandoning apparatus main body, described water collector will
The inner chamber of described flow abandoning apparatus main body is divided into diversion cavity that is setting up and down and being mutually communicated and abandoned stream chamber, described diversion cavity
Dismountable basket grid is inside installed, water inlet, delivery port and abandoned stream mouth are provided with described flow abandoning apparatus main body, it is described
