Description
[technical field]
The invention belongs to rainwater pollution control technology and recycling field, specifically a kind of overpass rainwater
Primary filter and retention device.
[background technology]
With the fast development of Urbanization in China and the overpass network system, the gathering ground of the waterproof road in city
Product constantly amplification, causes the original water body Natural Circulation path in city and flood runoff generation characteristic to occur significant changes, thus brings rain
The problems such as water resource utility model, municipal Storm Sewer Network load increase and urban waterlogging take place frequently.
In addition, the road surface erosion that driving vehicle is caused with pavement friction on overpass, tire wear, vehicle exhaust, combustion
Oil and oil leakage etc. can cause rainwater runoff pollution, rainwater is carried substantial amounts of silt, SS, organic
Each pollutant such as thing, nutriment, heavy metal and grease.Wherein, early-stage rainwater pollution level highest, pollutant load is reachable
As many as several times to ordinary municipal sewage.
How to realize that the early-stage rainwater of overpass is quickly collected, stored and abandoned stream, the primary for completing middle and later periods rainwater is net
Change, can not only mitigate the processing load of follow-up rainwater purification system, reach control rainwater pollution and realize Rainwater Resources profit
Purpose, is also to meet the need for China carries forward vigorously sponge urban construction at present, will have in green urban construction field
Broad prospect of application.
At present, existing rainwater-collecting and the retention device (patent No.:CN200580040462.5) use and pass through amount of rainfall
Number control the keying of ball-cock assembly, but the apparatus structure is complicated, and filter screen is easily blocked, and is more applicable for runoff more clean
Rain water on roof, be not suitable for applying again in the more overpass rain water collecting system of impurity particle.In addition, a kind of overhead road surface
Inlet for stom water collects the method (number of patent application of rainwater installation and Collection utilization rainwater:CN201610066187.4), in abandoned stream rain
Bucket top sets collection roof drain, collects the bridge floor that roof drain is higher by overhead road surface, can be realized from source is collected to early-stage rainwater
And the abandoned stream of the dirtier rainwater of bottom, but the device needs to change or transforms existing overpass roof drain, and how
Installed and hidden on the overpass built up and be higher by the inlet for stom water of bridge floor and there is certain difficulty, therefore the invention device
Popularization and application will be by a definite limitation.In the prior art, viaduct rainwater purification and Collection utilization integrated approach and system
(number of patent application:CN201310388987.4), using gravity sediment by rotational flow technology and Purification principle, respectively
Suspended particulate and organic-inorganic pollutant are efficiently removed, but need to set cistern and cyclone separator, is existed
