Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the 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:Purification storage room 7, housing is provided with the purification storage room 7, the housing is sequentially provided with water inlet 4, delivery port 9 and overfall 8 from the bottom to top, Filtering storage layer 6 is provided between water inlet and delivery port in the housing;Outside the delivery port 9 and purification storage room 7 Drainpipe 10 is connected with each other.
Specifically, as shown in figure 4, water inlet 4 be perforated baffle, the hole of multiple vertical direction is equipped with perforated baffle, On the one hand can pass through rainwater, on the one hand can fix filtrate.When the height of rainwater is stored up less than overfall 8 and higher than filtering Rainwater is because Action of Gravity Field can enter filtering storage layer 6 and be discharged through delivery port 9 and drainpipe 10 when depositing layer 6;Can be with profit Rainwater is extruded into delivery port 9 with negative pressure device, the height that drainpipe 10 is set is less than delivery port 9, using siphon principle, rainwater warp Drainpipe 10 is discharged, and negative pressure device can be suction pump etc., and the vacuum magnitude for being added in filtering storage layer 6 is main by filtering storage layer 6 filtrate density determines that this kind of mode can accelerate filtering rate.
In the light rain period, rainwater can be discharged by filtering storage layer 7 from delivery port 9 from the bottom to top due to suction function To in drainpipe 10, filtering storage layer 7 can effectively go suspension, part heavy metal ion, organic matter, colloidal particles in water removal Deng 90% solid suspension.
In the heavy rain period, rainwater then without filtering, due to Action of Gravity Field, enters from overfall 8, rapidly from drainpipe 10 Discharge.In order to speed rain-water drainage speed, overfall 8 can use siphon principle so that rainwater is quickly arranged to drainpipe 10.Overflow The maximum drainage rates of head piece 8 are 0.11m3/s。
The housing that the present invention is provided with storage room is purified, in the light rain period, rainwater is from the filtering in purification storage room Storage layer 6 is passed through, and is realized the abandoned stream of rainwater, is collected and purification function, reduces the Rainwater Quality difference of collection, is conducive to back Receive;And in the heavy rain period, can be with Quick drainage
Wherein, also including abandoned stream room 3, the middle and upper part of the abandoned stream room 3 is provided with crest of weir, the crest of weir and the purification storage Room 7 connects.Specifically, the bottom of abandoned stream room 3 can collect just rain, while the large granular impurities such as part leaf branch are collected, and in Rain is then entered into purification storage room 7 from crest of weir.
Wherein, spoil disposal room 5 is additionally provided with the purification storage room 7, the housing is suspended in the purification storage room 7 In, the spoil disposal room 5 is located at housing lower section.Regular maintenance includes:The sludge of spoil disposal room 5 and impurity are inhaled by silt pumping car Go out;Periodically remove the impurity of abandoned stream room 3.
Wherein, filtering storage layer 6 bottom is additionally provided with coupled discharge outlet 14, the discharge outlet 14 and the outer row Water pipe 10 is connected.Specifically, discharge outlet 14 is constantly in opening, 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 delivery port 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 Action of Gravity Field or siphon principle Flushing operation, then discharged from discharge outlet 14, it is possible to achieve during heavy rain, the filtrate of rainwater backwash filter storage layer 6 from top to bottom, Impurity and silt for rinsing out etc. enter spoil disposal room 5, in the regular maintenance stage, periodically impurity and silt are removed from spoil disposal room 5; During non-rainfall, it is possible to use siphon principle so that the inside of filtering storage layer 6 passes through higher than the rainwater of the horizontal plane of drainpipe 10 Drainpipe 14 is discharged, so as 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 sequentially provided with chrysotile layer 11, quartz sand layer 12 and cobble Layer 13.Specifically, being provided with fixed plate in the filtering storage layer 6, for fixing filter packing, make filter packing mutual Pollution.Filtering storage layer 6 can effectively go in water removal that suspension, part heavy metal ion, organic matter, colloidal particles etc. are poisonous to be had Evil pollutant.The particle diameter of the boulder bed 13 is 15-25mm;Thickness be 80-100mm, the thickness of the quartz sand layer 12 be 60- 80mm.Chrysotile layer 11 plays a part of to store water, and chrysotile layer 11 uses fire stons cotton material, and 11 volume of the chrysotile layer are 0.1m3, density is 1000kg/m3, infiltration coefficient is 20%, and storage capacity is 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, jag is provided with the top of the housing, institute's overfall 8 is located at the jag;The water inlet 4 is located at The housing bottom.
Wherein, the top of abandoned stream room 3 sets rainwater grid 1 and rain pipe 2.Specifically, the supplied materials of rainwater has two ways:1st, lead to Rainwater grid on passing by one's way enters the system, and large-sized solid impurity is not entered into the system;2nd, this is entered by urban rainwater pipeline System.
Wherein, purification storage room 7 upper end is additionally provided with access hole 15, for routine testing and the opening of maintenance.
The present invention discloses a kind of rain water drainage purification and storage system, and the system can be former by siphon in light rain state Reason or suction pump make rainwater from bottom to up by filtering storage layer, are discharged through delivery port and drainpipe, make the Rainwater Quality of collection Difference reduces, beneficial to recovery;In heavy rain state, rainwater can be discharged rapidly through overfall and drainpipe from top to bottom.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
