Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Following instance
For illustrating the present invention, but it is not limited to the scope of the present invention.
As shown in Figure 1, Figure 2 and Figure 3, the present invention provides a kind of rain water drainage purification and storage system, including：Purify storage room
7, the purification storage room 7 is interior to be equipped with shell, and the shell is equipped with water inlet 4, water outlet 9 and overflow port 8 successively from the bottom to top,
Filtering storage layer 6 is equipped between water inlet and water outlet in the shell；Outside the water outlet 9 and purification storage room 7
Drainpipe 10 is connected with each other.
Specifically, as shown in figure 4, water inlet 4 is perforated baffle, the hole of multiple vertical direction is equipped in perforated baffle,
On the one hand rainwater can be made to pass through, on the one hand can fixes filtrate.When the height of rainwater is less than overflow port 8 and higher than filtering storage
Rainwater can enter filtering storage layer 6 due to gravity and is discharged through water outlet 9 and drainpipe 10 when depositing layer 6；It can be with profit
Rainwater is extruded into water outlet 9 with negative pressure device, the height that drainpipe 10 is arranged is less than water outlet 9, utilizes siphon principle, rainwater warp
Drainpipe 10 is discharged, and negative pressure device can be suction pump etc., is added in the vacuum magnitude of filtering storage layer 6 mainly by filtering storage layer
6 filtrate density determines in this way, can accelerate filtering rate.
In the light rain period, rainwater can be discharged by filtering storage layer 7 from water outlet 9 from the bottom to top due to suction function
Into drainpipe 10, filtering storage layer 7 can effectively remove suspended matter in water, part heavy metal ion, organic matter, colloidal particles
Deng 90% solid suspension.
In the heavy rain period, rainwater is then entered, rapidly from drainpipe 10 without filtering due to gravity from overflow port 8
Discharge.In order to speed rain-water drainage rate, siphon principle may be used in overflow port 8 so that rainwater is quickly arranged to drainpipe 10.It overflows
The maximum drainage rates of head piece 8 are 0.11m3/s。
The shell that the present invention is equipped in purifying storage room, in the light rain period, rainwater from purification storage room in filtering
Storage layer 6 is passed through, and is realized abandoned stream, collection and the purification function of rainwater, so that the Rainwater Quality difference of collection is reduced, be conducive to back
It receives；And it, can be with Quick drainage in the heavy rain period
Wherein, further include abandoned stream room 3, the middle and upper part of the abandoned stream room 3 is equipped with crest of weir, and the crest of weir is stored with the purification
Room 7 connects.Specifically, 3 bottom of abandoned stream room can collect just rain, it is collected simultaneously the large granular impurities such as part leaf branch, and in
Rain is then entered from crest of weir in purification storage room 7.
Wherein, spoil disposal room 5 is additionally provided in the purification storage room 7, the shell is suspended in the purification storage room 7
In, the spoil disposal room 5 is set to below the shell.Daily maintenance includes：5 sludge of spoil disposal room and impurity are inhaled by silt pumping car
Go out；Periodically remove 3 impurity of abandoned stream room.
Wherein, 6 bottom of filtering storage layer is additionally provided with coupled discharge outlet 14, the discharge outlet 14 and the external row
Water pipe 10 connects.Specifically, discharge outlet 14 is constantly in open state, because the bore of discharge outlet 14 is smaller, in the light rain period, have
Sub-fraction rainwater can be discharged from discharge outlet 14, but most of rainwater is discharged by filtering storage layer 6 by water outlet 9；When sudden and violent
Rain period, rainwater can be anti-by carrying out from top to bottom from the side of filtering storage layer 6 due to gravity or siphon principle
Flushing operation, then be discharged from discharge outlet 14, when heavy rain may be implemented, the filtrate of rainwater backwash filter storage layer 6 from top to bottom,
Impurity and silt for rinsing out etc. are discharged into spoil disposal room 5, and the daily maintenance stage periodically removes impurity and silt from spoil disposal room 5；
During non-rainfall, siphon principle can be utilized so that 6 inside of filtering storage layer passes through higher than the rainwater of 10 horizontal plane of drainpipe
Drainpipe 14 is discharged, to ensure to filter drying of the storage layer 6 during non-rainfall.
As shown in figure 3, filtering storage layer 6 includes from top to bottom being equipped with chrysotile layer 11, quartz sand layer 12 and cobble successively
Layer 13.Specifically, being provided with fixed plate in the filtering storage layer 6, for fixing filter packing, keep filter packing mutual
Pollution.Filtering storage layer 6 can effectively remove that suspended matter in water, part heavy metal ion, organic matter, colloidal particles etc. are toxic to be had
Evil pollutant.13 grain size of the boulder bed is 15-25mm；Thickness is 80-100mm, and 12 thickness of the quartz sand layer is 60-
80mm.Chrysotile layer 11 plays the role of storing water, and chrysotile layer 11 is using fire stons cotton material, 11 volume of chrysotile layer
0.1m3, density 1000kg/m3, infiltration coefficient 20%, storage capacity 6400kg/m3.By taking Beijing as an example, in 10 years heavy rains
Under return period, per 1m3Chrysotile layer can store 24.4m2The rainwater of catchment area, is calculated by following formula：
P-storm recurrence period, takes 10；
T-charge for remittance time, takes 30min；
Q=Φ qF (2)
Q-rainwater flow, 5.3L/s；
Φ-runoff coefficient, takes 0.8；
F-catchment area.
Wherein, the top of the shell is equipped with jag, and institute's overflow port 8 is set to the jag；The water inlet 4 is set to
The housing bottom.
Wherein, 3 top of abandoned stream room setting rainwater grid 1 and rain pipe 2.Specifically, there are two types of modes for the supplied materials of rainwater：1, lead to
The rainwater grid for crossing road enters this system, and large-sized solid impurity is not entered this system；2, this is entered by urban rainwater pipeline
System.
Wherein, 7 upper end of purification storage room is additionally provided with access hole 15, is used for the opening of routine testing and maintenance.
The present invention discloses a kind of rain water drainage purification and storage system, and this system can pass through siphon original in light rain state
Reason or suction pump make rainwater by filtering storage layer, be discharged through water outlet and drainpipe from bottom to up, make the Rainwater Quality of collection
Difference reduces, and is conducive to recycling；In heavy rain state, rainwater can be discharged rapidly through overflow port and drainpipe from top to bottom.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
