Description
Technical field
The present invention relates to a kind of technology of field of environment protection, specifically a kind of shore bank step combined type rainwash
Pollution control system and its method.
Background technology
Rainwash pollution refer in rainfall rainwater and its runoff of formation flow through urban ground (such as shopping centre,
Residential area, parking lot, street etc.), assemble a series of polluters (such as crude oil, N, P, noxious material, organic matter), enter therewith
Enter water body, polluted surface water or underground water.City overland runoff is typical non-point pollution, wide, random with territorial scope
Property strong, complex genesis the features such as.Non-point pollution turns into the key factor of water environment pollution, and the water pollution in the U.S. 60% rises
Come from non-point source.The control polluted to urban runoff is one of emphasis of current Study of Water Environment, is realized to city overland runoff
Effective control, seek cost-effective urban runoff pollution control technology turn into the task of top priority.
The research to city overland runoff is in Rapid development stage both at home and abroad, and conventional method is exactly by ecology at present
The mode such as bank protection and Riparian Buffer Zone is handled Runoff contaminants.Cai Jing et al. have studied fascine, shrubbery pad, 3 kinds of grass planting
Different types of ecological revetment is acted on the retardation and contamination control of rainwash, as a result shows ecological revetment on control ground
There is good effect in terms of table runoff pollution, be mainly reflected in slow runoff water flow velocity and remove on the pollutants such as silt.Such as
Fascine is 28.00~33.33min to Average Delay Time of rainwash, can intercept 80.95% particle diameter for 30.07~
111.05 μm suspended solid, 92.58~97.15% water-soluble state nutritive salt and 75.75~91.24% silt knot can be retained
Close state nutritive salt；Shrubbery pad makes rainwash into the time 9.70~15.33min more delayed than naked slope in river course, can effectively catching
88.53~92.94% water-soluble state nutritive salt, but its interdiction capability to suspended particulate is weaker than fascine and grass planting bank protection；Grass planting
The ability of bank protection retardation rainwash is not as good as fascine and shrubbery pad, but it is to the suspended solid in rainwash compared with small particle
The interception rate of (14.89~52.63 μm) (SS) and silt reference state nutritive salt respectively reaches 85.93% and 80.53~
85.33%.Tang Hao et al. research finds that shore bank vegetation buffer strip can effectively reduce Runoff contaminants and enter river amount, Bermuda, height
The turf such as fescue grass buffer strip to SS interception rate up to more than 75%, to the interception rates of the nutrient pollutants such as nitrogen phosphorus about 35~
55%, significantly reduce river course non-point source pollution loading.
See on the whole, be concentrated mainly on shore bank band and ecological revetment to the research of city overland runoff control aspect in the past
Intercept, lack the research of structural type pollution control facility on the bank.Because rainwash has a large capacity and a wide range, with randomness and uncertain
Property the features such as, pollution factor is complicated, and easily collecting is handled, and is also not suitable for building sewage treatment facility.Conventional shore bank plant is delayed
Punching band floor space is larger, the built-up areas especially in each big and medium-sized cities, it is difficult to find the shore bank idle area of large area to build
If buffer strip, too short vegetation buffer strip can not meet runoff Water warfare requirement again.Therefore, pole is necessary to seek one kind because of ground system
Suitable rainwash groundwater pollution control, further cuts down Rainfall Runoff and enters river amount, reduce pollution of river risk.
The content of the invention
The present invention is complicated for prior art construction, takes larger bank ground area, while quantities is larger, needs on the whole
Want larger investment, the defect such as practicality is not strong, propose a kind of shore bank step combined type rainwash pollution control system and its
Method, using shore bank land-based area plot, sets water leg and buried U-shaped purifier, can intercept well outstanding in runoff water
The pollutant of floating solid, effectively purification rainwash, reduce pollutant enters river amount, and with good landscape effect.
The present invention is achieved by the following technical solutions：
