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.
Description
Technical field
The present invention relates to a kind of rainwater-collecting and utilize technical field, particularly a kind of catch-basin with isolation of purified initial rainfall function.
Background technology
The regeneration of rainwater is the effective way solving shortage of water resources, is also the important content building sponge city.The Collection utilization of rainwater not only can alleviate the environment pollution of early-stage rainwater, and can effectively prevent urban waterlogging problem.The problem of rainwater catchment system most critical is separated the initial rainfall of heavy contamination and later stage rainfall.Current common practice is discarded by early-stage rainwater, good for water quality later stage rainfall collected, recycle after simple process.Such way is that the environment pollution of initial rainfall does not well solve.Carried out a kind of research work with the catch-basin of isolation of purified initial rainfall function for this reason, object be by comprehensive system test, analyze and research solve existing catch-basin initial rainfall and later stage rainfall can not be collected respectively, and do not purify by precipitation, filtration, biodegradation, and make initial rainfall cause the problems such as environment pollution.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of catch-basin with isolation of purified initial rainfall function, 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, comprise Nei Jing, Wai Jing, well lid, screen cloth, settling pit, return hydrosphere, biologic packing material and rainwater-collecting pipeline, described Nei Jing and outer well are the inside and outside two-layer pipeline configuration with difference in height, early-stage rainwater falls into outer well, and rainfall later stage cleaner rainwater falls into interior well; Described screen cloth is connected on interior borehole wall top and outer well inwall, the floating substance in interception rainwater; Described Nei Jing, between outer well and screen cloth, form plenum chamber; The outer well inwall of described screen cloth lower end edge is provided with settling pit, retains the silt in early-stage rainwater; Be provided with the sloping baffle parallel with outlet edge before described settling pit outlet edge, baffle plate is fixed on screen cloth; The described hydrosphere that returns is fixed on the interior borehole wall, and lower than the position of settling pit, biologic packing material being set described returning in the plenum chamber in hydrosphere lower end and shaft bottom, the outer borehole wall bottom of plenum chamber that biologic packing material is housed has duct, outer borehole wall periphery is coarse sands layer, coarse sands layer is bed course; Nei Jing shaft bottom place is connected with drainage collection pipeline, extends to municipal drainage pipeline or rainwater utilization system; Described well lid is placed in Wai Jing top, and periphery is laid on bed course; Initial rainfall falls into outer well, intercepts floating thing and silt through screen cloth and settling pit, and the rainwater after the purification of biologic packing material layer enters coarse sands layer re-injection to underground water by duct; Later stage rainfall directly falls into interior well, enters rain water collecting system discharge or recycling by drainage collection pipeline.
There is a catch-basin for isolation of purified initial rainfall function, it is characterized in that: described catch-basin is provided with the settling pit being with annular folded structure, avoid silt to pass in and out biologic packing material layer and result in blockage.
Have a catch-basin for isolation of purified initial rainfall function, its preferred version is described catch-basin screen cloth is flexible connection, is convenient to dismounting.
Have a catch-basin for isolation of purified initial rainfall function, its preferred version is that described catch-basin is provided with in biologic packing material layer top and has water distribution effect loop configuration and return hydrosphere.
Have a catch-basin for isolation of purified initial rainfall function, its preferred version is that described duct is provided with several, ensures that the rainwater after purification can be recycled in underground in time.
Have a catch-basin for isolation of purified initial rainfall function, its preferred version is that described settling pit outlet edge is provided with ring baffle, avoids floating substance to enter biologic packing material layer.
Beneficial effect of the present invention: technical scheme manufacture of the present invention is simple, be easy to realize, solve existing catch-basin initial rainfall and later stage rainfall to be collected respectively, and do not purify by precipitation, filtration, biodegradation, and make initial rainfall cause the problems such as environment pollution.Catch-basin initial rainfall of the present invention and later stage rainfall are collected respectively, and early-stage rainwater is purified by precipitation, filtration, biodegradation, and the water after purification is recycled into underground by the duct on wall, recharge of groundwater; Later stage rainfall collects discharge or recycling by collection conduit.The setting of screen cloth and settling pit, ensures that biologic packing material layer does not block.Screen cloth is mobilizable, is convenient to clear up floating thing.In settling pit, silt can regular labor cleaning.The setting returning hydrosphere can ensure that the water outlet of settling pit evenly enters biologic packing material layer.Utilize position and the underground space of catch-basin, not independent land occupation.Therefore this structure is adopted to have significant economic benefit.
