Background technology
The rainwater runoff pollution as caused by rain drop erosion is the important component of pollution of area source.Especially dropped at one
The initial stage of rain accounts for the Initial Runoff of yielding flow 20%, wash away discharged 80% runoff blowdown flow rate.There is pollution certain
In the plant area (such as dangerous waste treatment plant, night soil-treatment factory, livestock and poultry treatment plant etc.) of project, comprising more multiple in initial rainwater runoff
Miscellaneous ingredient (such as organic matter, nitrogen, phosphorus, grease, heavy metal etc.).Due to rainwater runoff pollution have concentration change greatly, can give birth to
The characteristics such as the poor, complicated component of the property changed, if serious water pollution will be caused by being directly discharged into Storm Sewer Network.Therefore, to there is pollution
The rainwater of the on-site of project is collected and shuts off, and is very necessary to be respectively processed.
Meanwhile with deepening continuously to initial rainwater harm understanding, initial rainwater is cut there has been proposed various
The method of stream.But the discharge of the randomness of rainfall and noncontinuity, rainfall runoff is intermittent and irregularities result in
All there is very big difference in hydraulics, the actual condition of storm sewer system in the process of running etc., and then right with design condition
The specific implementation of initial rainwater retention engineering creates great difficulties.Current early-stage rainwater stream abandoning system is mainly volumetric method abandoned stream
System and tubule discarding system.
Volumetric method discarding system is suitable for the runoff rainwater of small catchment area, and initial rainwater runoff initially enters drainage tank,
After rainwater, enter Storm Sewer Network from the high water level outlet pipe overflow of setting, drainage tank primary rainwater closure enters sewage plant.But hold
There are be easy to cause Storm Sewer Network larger impact load, rainwater separating effect when rainwater flow is sufficiently large for area method discarding system
The problems such as poor.
Likewise, tubule discarding system is that carry out abandoned stream precontamination serious in the pipeline of rainwater conveying setting pipe with small pipe diameter on the way
Small flow runoff, it is general that rainwater inspection well is coordinated to be used together.Initial rainwater runoff initially enters rainwater inspection well, by small
Pipe discarding system is drained, and the later stage runoff more than tubule discarding system drainability enters back into rain water collecting system.But entire
Abandoned stream pipe is constantly in abandoned stream state in rainfall, is easy to cause sewage network larger impact load, meanwhile, in rainfall
Intensity is smaller and when rainfall is very big, abandoned stream amount is difficult to rationally control, and contamination control effect is unstable.
To sum up, existing various early-stage rainwater stream abandoning systems all have certain initial rainwater runoff that shuts off to varying degrees
Effect, but above system is easy to cause Storm Sewer Network or sewage network larger when coping with larger rainwater flow
Impact load, meanwhile, rainwater can not be carried out effectively quantitatively to shut off and detach.
