Description
Technical field
The present invention relates to rainwater preconditioning technique field, in particular to a kind of waterpower particle sorting apparatus.
Background technology
With the fast development of urbanization, the non-point pollution as caused by rainfall runoff is increasingly becoming urban water-body pollutant
Important sources.Pollutant in city rainfall runoff is mainly derived from wet deposition and city caused by precipitation elution atmosphere pollution
The leaching of city's impermeable surface pollutant washes away, and the latter accounts for more than the 90% of rainwater runoff pollution thing total amount.Particulate matter is city
The main carriers of city's impermeable surface pollutant, such as：Atmospheric sedimentation, vehicle exhaust, tire wear, Snow Agent, construction site
On the particulate matter such as deposit, solid refuse and percolate contain a large amount of pollutants (COD, nutrients, organic matter, heavy metal,
Pathogen etc.), finally it will all be migrated under rainwater elution, souring into receiving water body, and its ecological environment is produced tight
Endanger again.
Particulate matter in rainfall runoff also results in the rise of receiving water body turbidity, it is generally recognized that particulate matter is composing environment water
The potential component of body water quality deterioration.In addition, particulate matter enters meeting after urban drainage pipeline system under rainfall runoff souring
Deposition is produced in pipeline, pipeline sediment pollution and effectiveness factors are formed.
Therefore, rainwater drops to ground and forms runoff, can be containing particle and floating objects such as substantial amounts of silts, if not to rainwater
In particulate matter and floating object carry out intercept process be just exhausted directly to natural water, natural water will be polluted, at present
To the disposal options of the most use strainer filtering of rainwater, rainwater is subjected to simple filtering and pre-processed, but this strainer filtering
The problem of mode can bring a lot：1st, filter screen may be blocked, and hinder the discharge of rainwater to cause the waterlogging in city.2nd, floating object is blocked
Do not collected but after cutting, cleaning is inconvenient.

The operation principle of the present apparatus is：
At rainfall initial stage, rainfall is smaller, and rainwater enters storm sewer, then the water inlet pipe for passing through the present apparatus by surface runoff
2 direction with certain flow velocity along the tangent line of eddy flow cylinder 4 screws in eddy flow cylinder 4, is rotated in eddy flow cylinder 4, slightly
Big particle is gathered at the barrel of eddy flow cylinder 4 and moved downward in the presence of centrifugal sedimentation, and tiny particle is done in center
Rotary motion, final larger particle is deposited on the bottom of eddy flow cylinder 4, and tiny particle flows to low discharge with the rainwater of eddy flow
Effluent trough 9, the scum silica frost chamber formed into the outer wall of eddy flow cylinder 4 and scum silica frost barricade 5 and well body two side.In scum silica frost barricade 5
Under effect, floating object is blocked in this chamber, and current limliting wall 6 is flowed to from the lower end of scum silica frost barricade 5 and the space of well body 1 compared with clean water,
Overflowed through the low discharge overfall 11 on current limliting wall 6, eventually flow to outlet pipe 3.Rainwater is passing through scum silica frost barricade 5 and current limliting wall 6
When, because rainwater passes through secondary deflecting, so the relatively fine particle that rainwater contains will again occur to sink during rainwater deflecting
The particulate matter contained in drop, the rainwater finally flowed out is just fewer, reaches 90% clearance effect, and floating object is blocked completely
Cut in scum silica frost chamber.
When rainfall intensity becomes big, the amount of rainfall into the inner eddy flow of eddy flow cylinder 4 is more than through the discharge of low discharge effluent trough 9,
The water level of eddy flow cylinder 4 will rise, when rising to certain altitude, and rainwater runs past big flow effluent trough 8 and flowed out, and reach
During current limliting wall 6, due to the limited flow of low discharge overfall 11 on current limliting wall 6, the water level before current limliting wall 6 will rise, when upper
When being raised to certain altitude, the big flow overfall 10 that rainwater is run past on shunting wall flows out.
This device needs periodic maintenance, when needing to safeguard, can open well lid 12, enters from roof hole and carries out cleaning dimension
Shield.
