Description
Technical field
The present invention relates to suitable for a kind of inlet for stom water filtering and purifying.
Background technology
In urban infrastructure, Storm Sewer Network is very important component part, the safety in the entire city of relationship.With city
City greatly develop and the close attention to environment, the problem of people are gradually exposed to storm-water system, are paid close attention to further.China
Storm-water system mostly uses greatly in line mode, and rainwater is collected and is directly discharged to neighbouring river, lake by storm-water system
In pool.
In recent years, most cities rainwater in China's carries a large amount of pollutants and enters in river and lake, causes the dirt of river and lake water quality
Dye deteriorates.Rainwater is by washing away ground so that the pollutant carried in rainfall runoff increases, wherein suspending containing a large amount of
Object solid pollutant, water quality are poor.Such rainwater unprocessed converging by rainwater pipeline section, convert non-point source to point source
Pollution, causes impact pollutional load to river, lake, can cause large effect to water quality, and influence water body
Aquatic organism etc. is larger one of the reason of nearly urban water-body pollution control difficulty.If solid pollutant contained by rainwater is more,
Siltation is be easy to cause in rainwater pipe-line system, to reduce the conveyance capacity of pipeline and reduce the displacement volume of drainage pipeline.
In larger rainfall, city incity precipitation cannot timely be discharged, the waterlogging phenomenon in city may be deepened, to influence city
Normal use destroys the existing utility in city, causes economy and the loss of personnel.
Currently, the research of relevant issues of the China for carrying a large amount of solid pollutants in rainwater pipeline is seldom, almost do not have
There is practical application.And it is directed to the features such as rainwater flow velocity is very fast, and the residence time is short, filtration method is effective means, however how will
Method is effectively applied in practice, is bigger difficulty and challenge.Filtration method is not used widely at present.
In current technology, lacks device that is a kind of easy for installation and not consuming additional electrical energy, can effectively utilize
The characteristic of rainwater carries out the device of solid pollutant interception and collection.
Invention content
It is an object of the invention to a kind of inlet for stom water filtering and purifyings.
The technical solution adopted by the present invention is：
Environmental-friendly device suitable for intercepting suspended contaminant rainwater, including solid pollutant intercepting system, suspended pollution
Object collection system, big rainfall overflow mechanism, falsework.
The suspended contaminant intercepting system of the device is mounted in catch-basin, facilitates installation, using existing space place, compared with
For economy.
Suspended contaminant intercepting system is made of multistage filtering filtrate, is reached with the strainability by filtrate and is successively intercepted
Effect.
The suspended contaminant intercepting system is installed using tilting, dirty to help flow that suspended contaminant is driven to enter suspension
Contaminate object collection system.
The bottom of the suspended contaminant intercepting system, filtrate chunkings at different levels is provided with micro-pore so that part flow can
To enter the surface of next stage filtrate chunking across filter material layer, under a stream of water when the surface of drop impact to next stage filtrate chunking,
Using the kinetic energy of flow, the effect of a cleaning is carried out to the filtrate of next stage filtrate chunking, to improve the use longevity of system
Life.
Suspended contaminant collection system is after a certain time taken out collection system using movable device, is carried out dirty
The cleaning for contaminating object, to facilitate the long-time service of device.
There are certain spaces for the device lumen, and when rainfall is larger, rainwater can not be preferably by filtering layer, and lumen can be with
Overflow is carried out, ensures the drainage efficiency of catch-basin.
Beneficial effects of the present invention：
The device of the invention can effective solution rainfall when, rain drop erosion ground drives more suspended contaminant to enter rainwater
In pipeline, thus the problem of causing effect of reservoir siltation overcurrent in rain pipe.The device of the invention can effectively prevent greatly simultaneously
After amount ground pollution object enters storm sewer, the problem of water pollution caused by being emitted into water body and water environment destroy.
The present invention utilizes multistage filtrate so that rainwater has enough times of contact with filter layer, and pollutant can be preferable
Intercepted by filtrates at different levels, to realize preferable filter effect, have preferable foreground and practical value.
The filter material layer of the present invention is installed using interval, and the cleaning of lower layer's filter material layer is carried out using the kinetic energy of flow.
The present invention is filtered process using the kinetic energy of rainwater, does not expend the extra energy individually, relatively inexpensive.
Specifically：
The device of the invention, can be with：
Solid pollutant in rainwater effectively can be filtered interception by 1 the device of the invention, to prevent pollutant dirty
Contaminate water body environment and the effect of reservoir siltation carrying capacity of pipe in pipe-line system.
2 classification filter material layers can carry out interception filtering for various sizes of pollutant, increase pollutant and filter layer
Time of contact and area, have preferable effect.
3 present invention do not expend the additional energy, relatively inexpensive.
While 4 the device of the invention do not influence draining and the audit function of catch-basin, the expansion of pollution can be preferably controlled
It dissipates, avoids having an adverse effect to environment and personal safety.
5 installations are simple, of low cost, make simple.

Specific implementation mode
A kind of inlet for stom water filtering and purifying as shown in Figure 1, including big rainfall overflow ducts 1, big rainfall overflow ducts
Effect be that, when precipitation is larger, when rainwater cannot drain by the way that solid pollutant intercepting system is smooth, a large amount of rainwater is straight
It connected overflow ducts to enter in storm sewer 5, and ensured that rainwater can drain in time.Solid pollutant blocking apparatus 3 and suspension
Contaminant collecting device 2 is mounted on falsework 4.Rainwash rainwater is flowed by well lid in catch-basin, and rainwater first passes through solid
Body pollution object blocking apparatus 3 realizes the separation of rainwater and solid pollutant.A part of suspended contaminant is intercepted at filter material layer
On, another part suspended contaminant is collected in by the movement of flow in suspended contaminant collection device 2.Filter material layer passes through
The installation at interval and different angle so that pollutant can successively enter internal layer suspended contaminant collection device 2（a）It is outstanding with outer layer
Floating contaminant collecting device 2（b）In, suspended contaminant collection device can periodically take out the collection and cleaning for carrying out pollutant,
To ensure the continual and steady operation of system.When rainwater exits into next stage filtrate chunking from upper level filtrate chunking simultaneously, rain
There is water certain kinetic energy, the transformation that rainwater can be by momentum to momentum to be shelled to the pollutant intercepted in filtrate chunking
From to reach certain cleaning action.
Preferably, the filtrate chunking of described device is using multistage filtrate, by multistage different filtrate, can preferably into
The interception of row pollutant.
