Description
Technical field
The present invention relates to water treatment field, more particularly to sewage disposal, and specifically a kind of river rain dirt overflow port is pre-
Processing system.
Background technology
Vatch basin（Ditch）It is common a kind of technological means in confluence of rainwater and sewage system, its purpose is to the dirty separation of rain.Drought
There was only sewage in Ji Shiyin blow-off pipes, Vatch basin can stop sewage, flow to sewage treatment plant, during rainy season by part rainwater with
Sewage stops and flow to sewage treatment plant, and remainder then enters earth's surface waters by overflow type.Overflow water pollutant contains
Amount is higher, and earth's surface waters can be polluted, especially east China, south the region that rainfall is plentiful, overflow water body table over the ground
The pollution of water body is extremely serious.However, being directed to Vatch basin overflow water body, effective countermeasure and processing means are had no.
The content of the invention
It is an object of the invention to provide a kind of river rain dirt overflow port pretreatment system, this river rain is dirty to overflow
Head piece pretreatment system, which will solve primary rainwater of the prior art and rain dirt mixed flow, influences the technical problem of surface water quality.
It is described the present invention provides a kind of river rain dirt overflow port pretreatment system, including an external fixation device
Packeted soil basalis is provided with external fixation device, the top of the packeted soil basalis is provided with gravel packing,
Soil layer of being always or usually as specified is set on the top of the gravel packing, emergent aquactic plant is provided with the plain soil layer;
The external fixation device is made of at least four steel pipes set perpendicular to horizontal plane, is passed through between the steel pipe
Wire netting connects, and the aperture of the wire netting is less than 10mm, the top of the wire netting and the gravel packing
Top is concordant, the inner peripheral of the wire netting is provided with partition plate, the top of the partition plate is higher than the plain soil layer
20 ~ 70cm, the bottom of the partition plate is concordant with the bottom of the gravel packing, and at least two are provided with the partition plate
A overflow port.
Further, the height of the gravel packing is 0.5-1 m, and grain size of gravel is 10-20 mm, adjacent two
Porosity between a gravel is 0.484.
Further, the height of the plain soil layer is 10-20cm.
Further, the steel pipe is arranged on river bed, embedded depth 1-1.5m.
Further, at least two overflow ports are provided with the partition plate parallel to revetment side, any one overflow mouth width
0.6m, sets 1 overflow port every 1.4m, at least one overflow port is provided with the partition plate of embankment of vertical side, any one
The width of overflow port is 0.6m, and the overflow port is less than the top 20cm of partition plate, higher than ordinary water level 0.5m, with rain dirt floss hole
Bottom is concordant.
Further, the steel pipe top is higher than 20cm at the top of partition plate.
Specifically, the emergent aquactic plant includes but not limited to canna, calamus, iris, reed, cyperus alternifolius etc..
The principle of the present invention is：Continuous water stream channel is formed between gravel, when sewage by when, the suspended solid in water
(SS) because the reasons such as precipitation, physics interception, hydrodynamic force move to gravel table and contact precipitation.And due to the pipe stream formed between gravel
Hydraulics be beneficial to precipitation, therefore the effect of contact precipitation is more notable than natural rivers and creeks.Long-time and waste water
Gravel table and form biomembrane, biomembrane absorption, the organic matter absorbed in water are used for the metabolism of itself, conversion with degradation water
Pollutant.
Emergent aquactic plant can directly absorb the nutriment in sewage, be developed for its growth.Emergent aquactic plant passes through root
Absorb nourishment material（When especially sewage overflow amount is smaller, the residence time length of sewage, the absorbed ratio increase of pollutant）.
Aquatic plant yield is high, and substantial amounts of applied material is fixed in its organism.After harvesting, nutrients just can from system quilt
Remove.Organic nitrogen in waste water is with regard to that can be decomposed by the microorganisms and convert, and inorganic nitrogen is as indispensable in growing process
Material directly absorbed by plant, then removed by the harvesting of plant from waste water.
The present invention can carry out preliminary filtration, purification to the overflow sewage for entering river, remove the SS of wherein most, reduce it
Turbidity, and cut down a part of pollutant.
Specifically, the system length of the present invention is adjusted according to displacement, highly adjusted according to ordinary water level, width generally sets 1-
2m；Packeted soil base layer thickness is adjustable, and depending on trying actual conditions, river bed flatness can be effectively improved by being rationally laid with packeted soil,
Ensure the stability of whole system.
The preferably plain soil layer of the attached 10-20cm water penetrations in gravel packing surface, for planting emergent aquactic plant.Gravel packing
It is the main filtration of device, can effectively reduces the SS and the content of organic matter of water.
The present invention is compared with prior art, it has the technical effect that positive and obvious.The present invention being capable of preliminary purification river
The overflow sewage of littoral closure works system, can effectively reduce the SS and the content of organic matter of rain dirt overflow port overflow water body, and can go
Except a part of nitrogen and phosphorus pollutants, the preliminary purification for entering surface water body to overflow water body can be played.A kind of river rain of the present invention
Dirty overflow port pretreatment system floor space is small, and service life length, processing cost is low, is a kind of place to rain dirt overflow port sewage
Reason technology, application prospect are quite varied.
