Description
Technical field
The present invention relates to a kind of rainwater purification equipment, and in particular to a kind of Integral rain processing unit.
Background technology
With the quickening of urbanization process, Permeable stratum area dramatically increases on ground, pollutant at these fluid-tightly
Built up on face, when rainfall, pollutant is poured rainfall runoff system and forms rainwater runoff pollution by rain drop erosion ground.Rain
Water runoff pollution is a kind of diffusion contact scar, and pollutant enters natural water, causes water pollution, and the pollutant includes
The poisonous and harmful substances such as grain thing, organic matter, heavy metal.Therefore, urbanization process and industrialization development cause water source judgment and rain
Flood endangers getting worse.
With water source judgment and the aggravation of rain flood harm, rainwater is subject to Collection utilization and carries out the comprehensive regulation as water resource
Turn into important emerging problem.In overall city planning, most of combined drainage system that the past uses is changed a social system,
It is changed to separate system or the drainage system processed that dams.Serious with urban atmospheric pollution and ground pollution, rainwater runoff pollution is further
Seriously, especially the more early-stage rainwater of pollutant, the pollutant index peak of the early-stage rainwater of certain areas are much high
In typical urban sanitary sewage.Therefore, it is necessary to rainwater, especially early-stage rainwater are handled.
Collection processing of the China to early-stage rainwater at present is scarcely out of swaddling-clothes, and collects early-stage rainwater and does not allow only it to arrange
Enter water pollution water quality, and the purified treatment and reuse for early-stage rainwater then seldom consider, majority is directly discharged into municipal life
Sewage network.The pollutant concentration contained in early-stage rainwater is higher, especially road early-stage rainwater, is directly discharged into sanitary sewer
Net can bring larger load to sewage plant.
The content of the invention
In order to solve the above problems, the present invention provides a kind of Integral rain processing unit, described device include well body and
Cover plate above well body, the well body bottom set overflow wall, are divided into inside well body by the overflow wall from bottom to top
Decanting zone and filtering-infiltration area；

Embodiment 2
A kind of method for being handled using Integral rain processing unit in embodiment 1 rainwater is：
During rainfall, the early-stage rainwater warp of the pollutants such as particulate matter, suspension, floating object, nitrogen, phosphorus, oil and grease is carried
Flase floor 4 enters well body, and drainage bucket 5 can intercept the pollutants such as rubbish bigger in early-stage rainwater, leaf.
Under gravity, some big particulate matters can then be deposited in the decanting zone A of well body.With water level in the A of decanting zone
Rising, a small amount of rainwater is entered in Biomedia layer 9 by perforated drain pipe 13, after the processing of Biomedia layer 9, into rubble
Layer 8, then directly penetrate into underground by permeable geotextiles 7.
With the increase of rainfall, when water level rises to the position at the top of overflow wall 3, rainwater then can be from overflow wall 3
The connected entrance overflow of side enters filtering-infiltration area B, and underground is penetrated into after the processing of Biomedia layer 9.The bottom of baffle plate 6 is low
In the wall top of overflow wall 3, floating object, oil and grease can be then intercepted by baffle plate 6 in decanting zone A, rainwater from the flowing underneath of baffle plate 6,
Ensure that floating object, oil and grease will not enter filtering-infiltration area B.
When rainfall is more than the maximum processing capability of Biomedia layer 9, filtering-infiltration area B water level may proceed to rise,
When water level rises to the ttom of pipe of overflow pipe 12, the direct overflow of rainwater is drained, and ensures the normal operation of system.When rainfall terminates,
Decanting zone A most of rainwater may proceed to enter in Biomedia layer 9 by perforated drain pipe 13 penetrates into underground after processing,
Ensure that the pollutant that drainage bucket 5 is collected will not be immersed in water, while the particulate matter for being deposited in shaft bottom will not block perforation draining
Pipe.
10 kinds of plant is in Biomedia layer 9, the material such as nitrogen, phosphorus in can drinking up the rain.Root system of plant can be with counterweight
The pollutants such as metal are intercepted and adsorbed, while the microorganism around root system of plant can also drop to organic pollution
Solution.
