Description
Technical field
The utility model belongs to the technical field of pollution prevention, a kind of new old town rain sewage disposal system of specific design
System.
Background technology
Because of reasons such as history, domestic and international old town still remains drainage system technique.Drainage system technique is not only held
The conveying and discharge of city domestic sewage are carried on a shoulder pole, while be also the passing away of rainfall runoff, i.e. city point source and pollution of area source
Dual channel.After rainfall, flow increases with the increase of rainfall in the tubing giving sufficient strength of interflow, when pipeline flow is dry more than damming
During the conveying capacity of pipe, the dirty mixing water of unnecessary part rain will climb over the mode draining receiving water body such as overflow well/Vatch basin and make
Into pollution, this part combined sewage is referred to as combined system tube overflow (CSO).Sunk in combined system tube overflow containing substantial amounts of pipeline
Product thing, microorganism, black sordes matter etc., severe contamination urban water-body environment.The mode that overflow occurs for combined system pipe network has a lot,
And most basic thinking is to set overflow mechanism in the pipe end that dams, such as Vatch basin, dam pumping plant.But because old town is original
The historical reasons of pipe drainage scarce capacity, still there is part overflow during rainfall, this is the most obvious in heavy rain or strong rainstorms, now
Tube overflow gesture is big and anxious.
The method of domestic and international control pipeline overflow has diversified forms, is broadly divided into Sources controlling, pipeline technology control, storage
Deposit and regulate and store and the major class of end-o f-pipe -control four.Sources controlling is mainly LID technologies of taking, and reduces the water and water pollution of rainfall runoff；
Pipeline technology is controlled, and mainly has optimization interception ratio, pipe flushing etc.；Storage is regulated and stored, and is mainly subtracted by newly-built storage pond
Slow pipe drainage pressure；End purified treatment, mainly there is cyclone separator, pipe flushing technique etc..Watershed management opposite source is dirty
Dye control is effective, but to pipe network contamination control DeGrain.
At present, many patents, product attempt the control for collaborating tubing giving sufficient strength pollution load of overflow.It is such as entitled
Utility model patent (the application publication number of " general-purpose design method of overflow rain sewage on-the-spot ecological elimination technology "
CN101935133A region overflow modeling) is carried out using SWMM softwares, is dissolved structures while proposing step in-site ecological, should
Method there are problems that processing speed excessively；It is and for example entitled that " a kind of Combined sewer system is staggered the time flow-dividing control technique and control
Method " (application publication number CN102505749A) using central controller controls river pipe network, it is necessary to newly-built septic tank, it is and actual
Complex operation；And for example entitled " storage pond of tape handling function " (application publication number CN103193340A) utilizes storage pond settling zone
Rain sewage is handled, actual processing effect is limited, and continue overflow more than the rain sewage for pool volume of regulating and storing；And for example entitled " combined system
Storage pond controls technique and its control method in real time " (application publication number CN103343570A) utilization turbidity difference rain sewage, behaviour
Make complicated, also the rain sewage more than pool volume of regulating and storing continues overflow；And for example entitled " combined system underground Rainwater Storage Tank " (Shen
Please publication number CN104975648A) regulate and store storage, but later stage rainwater still polluted-water are carried out to early-stage rainwater.
