In one embodiment, the first discharge outlet 52 is corresponding with 61 position of first through hole but interval is arranged, the second discharge outlet
53 but interval settings corresponding with 64 position of fourth hole, are further sunk by the rainwater flowed out in swirl cylinder 50 through sediment by rotational flow room 10
Behind shallow lake, dross is imported by first through hole 61 and fourth hole 64 (being used when rainfall peak value) and retains room 20.
In another embodiment, the cylinder of the connection wall and swirl cylinder 50 between sediment by rotational flow room 10 and dross retention room 20
Wall shape is adapted, above-mentioned first discharge outlet 52 and 61 palette of first through hole, above-mentioned second discharge outlet 53 and fourth hole
64 palettes.
Specifically, when non-rainfall peak value carries out pollutant removal operation, rainwater is imported by inlet ductwork 51, utilizes rotation
The cyclonic action of flow cartridge 50, density are more than the suspended solids such as the silt of water and are pushed to periphery, and the barrel along swirl cylinder 50 falls into bottom
Portion's sand setting storage area；Density is less than the dross of water, and such as pop can and empty water bottle, the rubbish such as grease are pushed to central area, float on
On the water surface of central area.Arrow direction is water (flow) direction in wherein Fig. 1 to Fig. 6.
The diameter of swirl cylinder is according to formulaIt determines, wherein D is swirl cylinder diameter (m), and Q is rainwater peak value
Flow (m3/ s), π 3.14, q are design waterpower surface loading (m3/m2·s).The available depth of swirl cylinderWherein
H is swirl cylinder available depth (m), and t is swirl cylinder hydraulic detention time (s), remaining symbol is same as above.Waterpower when peak flow is stopped
The time is stayed to be at least 30s.
Rainwater is tentatively cleaned in swirl cylinder, forms half net rainfall water (containing part sand setting and dross), half net rainfall
Water is entered by the first discharge outlet 52 in dross retention room 20.Since dross retains the connection between room 20 and perpendicular stream sand setting room 30
Wall bottom opens up the second through-hole 62, and the density ratio water of above-mentioned dross is light, therefore can swim on the water surface, and the second through-hole 62 is located at
Bottom position, so dross will be filtered retains room 20 in dross.
Rainwater into perpendicular stream sand setting room 30 carries part sand setting, since sand setting density is larger, can be deposited on perpendicular stream sand setting
The bottom of room 30, and third through-hole 63 is opened in the middle part of the connection wall between perpendicular stream sand setting room 30 and balanced water-supplying chamber 40, therefore
The part sand setting in rainwater is trapped in perpendicular stream sand setting room 30, and clean rainwater can enter in balanced water-supplying chamber 40,
It is exported to rainwater storage tank or access Manual moist and is located in by discharge pipe line 42 after balanced water quality and water in balanced water-supplying chamber 40
Reason system.Third through-hole 63 is vertically to perpendicular stream sand setting room of the depth at least more than 1/3 times of perpendicular 30 bottom of stream sand setting room
Length in 30 parallel water (flow) directions.
Preferably, correspondence offers the second discharge outlet 53 on the barrel of swirl cylinder 50, and the second discharge outlet 53 is located at first row
52 top of the mouth of a river, sediment by rotational flow room 10 and dross retain and are further opened with fourth hole 64, four-way in the connection wall between room 20
Hole 64 is located at 61 top of first through hole.Second discharge outlet 53 is corresponding with 64 position of fourth hole.First discharge outlet 52 and first is logical
The shapes and sizes in hole 61 are identical, and the second discharge outlet 53 is identical as the shapes and sizes of fourth hole 64, and the first discharge outlet
52 area is less than the area of the second discharge outlet 53.
Second discharge outlet 53 and fourth hole 64 are set, it is therefore an objective to be used as high flow capacity channel.I.e. during the rainfall,
If the rainfall of certain period is excessive, the rainwater higher than designed capacity is drained by high flow capacity channel, reduces sediment by rotational flow room 10
Water body turbulent flow prevents interference of the flowed fluctuation to sand setting slag removal.
Further, it erects and is further opened with fifth hole 65 in the connection wall between stream sand setting room 30 and balanced water-supplying chamber 40,
Fifth hole 65 is located at the top of 63 vertical direction of third through-hole.The area of fifth hole 65 is more than the area of third through-hole 63.
The fifth hole 65 is also used as high flow capacity channel, is no longer repeated herein.
It should be noted that the fifth hole 65 builds up the form of rectangular weir, overflow discharge capacity according to
It determines, wherein A is the discharge capacity (m of rectangular weir3/ s), b is that weir is wide (m), and g is acceleration of gravity, and H is weir headwater depth (m), m
For correction factor, value 0.4-0.6.Rectangular weir can realize that overflow capability is larger compared with low water level overflow, reduce the flow pair of overflow
Third through-hole 63 is discharged the interference of flow.
The top of sediment by rotational flow room 10 is provided with the first soil cleaning port 11.The top of dross retention room 20 is provided with second and removes contamination
Mouth 21.The top of perpendicular stream sand setting room 30 is provided with third soil cleaning port 31.The top of balanced water-supplying chamber 40 is provided with the 4th soil cleaning port
41.Municipal administration suction-type sewer scavenger can be 3~6 by above-mentioned soil cleaning port suction foot deposit and surface scum, cycle of removing when dry season
A month.
The utility model embodiment can carry out prefabricated when handling water smaller (being less than 700L/S)；When processing water compared with
Greatly (be more than 700L/S) when, can scene build by laying bricks or stones, therefore the utility model embodiment has processing flow in extensive range, builds flexible
Convenient advantage.
It can be seen from the above description that the above embodiments of the present invention achieve the following technical effects：
1, sediment by rotational flow room and dross retain room, erect stream sand setting room synergy, improve to initial rainwater slagging-off sand setting
Effect；
2, the energy is not consumed, Maintenance and Repair are convenient；
