Description
Technical field
The present invention relates to municipal water treatment systems field, shut off online processing exhaust system in particular to a kind of fragment.
Background technology
For separate system storm sewer, each floss hole is no any River Closure Measures at present, is directly discharged to nature
First rain when water body, sewage during such fine day and rainy day has all been discharged to natural water, natural water is caused seriously
Pollution.
For collaborating tubing giving sufficient strength, many regions are all to be discharged into sewage by a Vatch basin of the trunk sewer through end at present
Factory is managed, when the rainy day, rainwater and sanitary sewage are discharged to natural water through Vatch basin.During actual motion, in order to save space and
Project cost will generally collaborate the receipts water area area that exhaust system is responsible for and set big as far as possible, then done in sewage
The end of pipe sets a discharge outlet to concentrate discharge of shutting off.There is the problem of very big in this drainage system, Sometimes When It Rains receive water
The first rain and later stage rainwater in region mix, and are not carried out the separation of clear water and sewage, finally in end initial rainwater tune
The first rain pollutant concentration that reservoir is regulated and stored is very low, containing the rainwater that a large amount of later stage is clean, and is discharged to the rainwater in natural water
Also containing a large amount of just rain, serious runoff pollution is generated to natural water.Since the area that receipts water area covers is too big, do not have
Delay time of the rainwater on pipeline or rainwash is fully taken into account, otherwise first rain is to be directly discharged to natural water initiation
Serious contamination accident or be to mix to be flowed in sewage treatment plant with a large amount of later stage clean rainwater seriously to increase at sewage
The processing pressure of factory is managed, the regulation and control for initial rainwater and later stage rainwater are simultaneously unreasonable, it is impossible to are totally separated from.For example,
Storage pond has been built in certain city in the area close to urban sewage treatment system, it is assumed that M areas are apart from the storage pond 1Km, M area
Interior urban rainwater is directly discharged to storage pond by pipe network, the city initial rainwater in M areas be fully discharged into storage pond when
Between be T1.For exceeding the area apart from storage pond farther out in the region, it is assumed that air line distance of the N areas apart from storage pond is
The time that the city initial rainwater in 10km, N area is fully discharged into storage pond is T2, and from the point of view of time length, T2 is obviously remote
Much larger than T1.And after initial rainwater has been expired in storage pond collection, the rainwater exceeded begins to be automatically discharged into natural water, adjusts
Since reservoir be T3 to the time that natural water discharges start to collect rainwater to.During actual motion, if only taking M areas into account
Rainwater emission behaviour, i.e. the initial rainwater in M areas can enter the cleaning of sewage disposal system intermediary and later stages by storage pond
Rainwater can be discharged into natural water, and T3 is needed to be more than T1, once beyond T3, storage pond is immediately discharged to natural water, and
N areas flow to the rainwater of storage pond and still pollute very serious initial rainwater at this time, i.e. T3 is less than T2, and nothing is discharged to natural water
It is doubtful to cause very serious pollution.
If only in view of the rainwater emission behaviour in N areas, i.e. T3 is more than T2, and the initial rainwater in that N areas can lead to
It crosses storage pond to enter in urban sewage treatment system, be handled well.But for M areas, M areas have largely
Later stage clean rainwater be also discharged into urban sewage treatment system within the time of the initial rainwater in storage pond discharge N areas
In, such emission behaviour can cause very big processing pressure to urban sewage system.In addition, M areas and N during actual motion
The pipe network in area is generally connection situation, and due to the difference of distance, the delay on road acts on, and the initial rainwater in N areas may
The later stage clean rainwater in serious pollution M areas, also results in the unreasonable of rainwater emission behaviour.
