Description
Technical field
This utility model belongs to technical field of sewage treatment equipment and in particular to a kind of manpower rapid-infiltration of purifying rainwater runoff
System.
Background technology
Pollutant type in water body mainly includes inorganic pollution (as various hydrocyanic acids, potassium cyanide, sulphuric acid, nitric acid
Deng), pathogenic microorganism (as various pathogenic bacterias, virus and parasite etc.), nutrient for plants (as nitrate, nitrite, ammonium salt and
Phosphate etc.), oxygen consumption pollutant (as carbohydrate, protein, oils and fatss, lignin, cellulose etc.) and heavy metal ion is (such as
Cadmium, chromium, lead, arsenic, hydrargyrum etc.) five big class.Wherein, the heavy metal ion of Water Environment System, tool is entered by natural source and artificial source
Toxic, be difficult to degrade, be easy to the features such as accumulation, while leading to environmental quality to deteriorate, can be directly or indirectly strong to the mankind
Kang Zaocheng seriously threatens.Therefore, heavy metal pollution problem is always focus of concern.
With the quickening of urbanization process, the scale of industrial occupancy, shopping centre and residential block constantly increases, Permeable stratum area
Increasing makes rainwater infiltration capacity subtract greatly, and runoff volume accordingly increases, and the Urban Rainwater Runoff Pollution problem causing also is on the rise.
Heavy metal is one of most typical pollutant in Urban Rainwater Runoff Pollution, and its main source is:By motor vehicle exhaust gases, industry
The approach such as flue dust, fuel combustion, wind-drifting sand enter the heavy metal of air, enter earth's surface, wherein wet deposition by dry, wet deposition
The main heavy metal that carried in the form of rainfall enters receiving water body, and the heavy metal of dry deposition accumulation in rainfall leaching, wash away work
With in lower entrance rainfall runoff.Rainwater runoff pollution has certain randomness and sudden, and pollution range is wide, a huge sum of money in rainwater
The impact of the factors such as the contaminated source emission of height of genus content, season, rainfall, rain time interval, wind direction is larger, no
There is larger difference in the content with heavy metal in the rainfall runoff of area, the heavy metal of the most different degrees of aggravation urban water-body
Pollution it is also possible to cause heavy metal pollution of soil by pollution transportation.As can be seen here, the heavy metal in rainfall runoff is carried out
Control, be the important channel effectively alleviating the heavy metal pollution problem of ground surface environment water body.
For rainfall runoff heavy metal pollution problem, what research was more at present has soil filtration, Rain Garden, green room
The technology such as top, ecological tree pond, permeable road surface, greenery patches buffer strip, wherein soil filtration technology is cut to rainwater runoff pollution thing
Subtract effect very notable, be one of rainfall runoff control method of most economic benefit.But, Efficiency for Soil Aquifer Treatment often exists
Floor space is big, hydraulic load is low, easily block the problems such as, in the city of land used growing tension, the application of this technology and popularization
Difficulty is larger.And manpower rapid-infiltration technology is a kind of Novel sewage treatment technology developed in recent years, it adopts permeance property good
Natural or artificial dielectric replace soil as main diafiltration material, the shortcoming overcoming conventional soil diafiltration techniques, for effective
Rainwater runoff pollution is controlled to provide possibility.However, the existing research with regard to manpower rapid-infiltration technology, majority concentrates on it to organic
In the control of the pollutant such as thing, ammonia nitrogen, nitrate nitrogen, total phosphorus, anion surfactant, float, the selection of filler is also mostly to be
To remove above-mentioned pollutant as starting point, the research of heavy metal Environmental capacity is related to less.Therefore, seek and there is good weight
The manpower rapid-infiltration filler of metal purification effect, promotes the filterability of manpower rapid-infiltration pond heavy metal by optimizing filling-material structure
Energy, absorption property and microbial metabolism performance, reduce the content of heavy metal while degrading water body common contaminant, both permissible
Application that is abundant and developing manpower rapid-infiltration technology, can be that city rainfall runoff heavy metal pollution controls the new choosing of offer again
Select.
