Abstract
The invention provides a catch basin with an incipient rain separation and purification function. The catch basin is characterized by comprising an inner well, an outer well, a well lid, a screen, a settling tank, a water return ring and biological stuffing; the inner well and the outer well adopt an inner pipeline structure and an outer pipeline structure which are different in height; the screen is connected to the top end of the wall of the inner well and the inner wall of the outer well; a cavity is formed among the inner well, the outer well and the screen; when incipient rain falls into the outer well, floatage and silt are blocked by the screen and the settling tank; rain overflows from the settling tank, passes the water return ring, uniformly passes through the biological stuffing, and is purified by microbes in the biological stuffing; purified rain water enters a coarse sand layer outside the catch basin through porous channels, and is then injected into groundwater; later rainfall falls into the inner well directly, and enters a rain water collection system through a water draining and collecting pipeline for discharging or recycling. The catch basin is simple in structure and maintenance management, small in occupied area, and obvious in economic benefit.

Background technology
The regeneration of rainwater is an effective way for solving shortage of water resources, is also a weight for building sponge city
Want content.The Collection utilization of rainwater not only can mitigate the environmental pollution of early-stage rainwater, and can effectively prevent urban waterlogging
Problem.The problem of rainwater catchment system most critical is to separate the initial rainfall of heavy contamination with later stage rainfall.Generally do at present
Method is to discard early-stage rainwater, and the preferable later stage rainfall of water quality is collected, and is recycled after simple process.Such way is
The environmental pollution of initial rainfall is without solution well.Carry out for this to a kind of rain with isolation of purified initial rainfall function
The research work of well, it is therefore an objective to tested by comprehensive system, the existing catch-basin of solution of analyzing and researching can not drop the initial stage
Rain is collected respectively with later stage rainfall, and can not be purified by precipitation, filtration, biodegradation, and initial rainfall is caused
The problems such as environmental pollution.
The content of the invention
To solve above-mentioned technical problem, it is an object of the invention to provide a kind of rain with isolation of purified initial rainfall function
Well, concrete technical scheme is as follows：
A kind of catch-basin with isolation of purified initial rainfall function, catch-basin is divided into inside and outside two-layer, including Nei Jing, outer
Well, well lid, screen cloth, stillpot, hydrosphere, biologic packing material and rainwater-collecting pipeline are returned, the Nei Jing and outer well are with difference in height
Inside and outside two-layer pipeline configuration, early-stage rainwater falls into Wai Jing, and rainfall later stage cleaner rainwater falls into Nei Jing；The screen cloth connects
It is connected on interior borehole wall top and outer well inwall, intercepts the floating substance in rainwater；Formed between the Nei Jing, outer well and screen cloth empty
Chamber；The outer well inwall of the screen cloth lower end edge is provided with stillpot, retains the silt in early-stage rainwater；Before the stillpot outlet edge
The sloping baffle parallel with outlet edge is provided with, baffle plate is fixed on screen cloth；The hydrosphere that returns is fixed on the interior borehole wall, and less than heavy
The position of shallow lake groove, arranges biologic packing material, the plenum chamber equipped with biologic packing material in the plenum chamber for returning hydrosphere lower end and shaft bottom
Outer borehole wall bottom is provided with duct, and outer borehole wall periphery is coarse sands layer, is bed course on coarse sands layer；Nei Jing is connected with draining at shaft bottom
Collection conduit, extends to municipal drainage pipeline or rainwater utilization system；The well lid is placed in Wai Jing tops, and periphery is laid on road surface
On bed course；Initial rainfall falls into Wai Jing, and Jing screen clothes and stillpot intercept floating thing and silt, the rain Jing after the purification of biologic packing material layer
Water passing hole channel enters coarse sands layer re-injection to subsoil water；Later stage rainfall falls directly into interior well, and by drainage collection pipeline rain is entered
Water collection system is discharged or recycled.
A kind of catch-basin with isolation of purified initial rainfall function, it is characterised in that：The catch-basin is provided with band annular
The stillpot of folded structure, it is to avoid silt turnover biologic packing material layer results in blockage.
A kind of catch-basin with isolation of purified initial rainfall function, its preferred version is that the catch-basin screen cloth is activity
Connection, it is easy to disassemble.
A kind of catch-basin with isolation of purified initial rainfall function, its preferred version is the catch-basin in biologic packing material
Layer top is provided with returns hydrosphere with water distribution effect loop configuration.
A kind of catch-basin with isolation of purified initial rainfall function, its preferred version is provided with several for the duct,
Ensure that the rainwater after purification can be recycled in time in underground.
A kind of catch-basin with isolation of purified initial rainfall function, its preferred version is provided with for the stillpot outlet edge
Ring baffle, it is to avoid floating substance enters biologic packing material layer.
Beneficial effects of the present invention：Technical scheme is simple to manufacture, it is easy to accomplish, solve existing catch-basin not
Initial rainfall can respectively be collected with later stage rainfall, and can not be purified by precipitation, filtration, biodegradation, and be caused
The problems such as initial rainfall causes environmental pollution.The catch-basin initial rainfall of the present invention is collected respectively with later stage rainfall, early-stage rainwater
By precipitation, filter, biodegradation purified, the water after purification is recycled into underground by the duct on wall, addedly under
Water；Later stage rainfall is collected discharge or is recycled by collection conduit.The setting of screen cloth and stillpot, it is ensured that biologic packing material layer is not blocked up
Plug.Screen cloth is mobilizable, is convenient to clean floating thing.Silt can regular labor cleaning in stillpot.Return the setting energy of hydrosphere
Enough ensure the water outlet of stillpot even into biologic packing material layer.Position and the underground space using catch-basin, does not individually take soil
Ground.Therefore there is significant economic benefit using this structure.
