Description
Technical Field
The invention belongs to the technical field of drainage system regulation and control, and particularly relates to a method for controlling sewage in a sewage intercepting pipe of each shunting facility in a drainage system to flow into a sewage main pipe during rainfall.
Background
In the current society, the urbanization is developed more and more rapidly, the area of a city is larger and larger, the structure of a municipal drainage pipe network is more and more complex, and the treatment pressure of a municipal water body treatment system is larger and larger.
Traditional urban pipe network system all adopts a big rainwater processing system to be responsible for a very big catchment region, because catchment region is too big, does not fully consider the delay time of rainwater on pipeline or surface runoff, leads to a large amount of mixings of initial stage rainwater and later stage rainwater. For example, a regulation and storage tank is built in a region close to a municipal sewage treatment system in a city, and assuming that an M region is 1Km away from the regulation and storage tank, municipal rainwater in the M region is directly discharged to the regulation and storage tank through a pipe network, and the time for completely discharging the initial municipal rainwater in the M region to the regulation and storage tank is T1. For the region far away from the storage tank beyond the region, assuming that the straight distance from the N region to the storage tank is 10km, and the time for the initial city rainwater in the N region to be completely discharged into the storage tank is T2, the time is obviously far greater than T1 in T2. And after the storage tank is full, the excess rainwater begins to be automatically discharged into the natural water body, and the time from the beginning of collecting the rainwater to the beginning of discharging into the natural water body of the storage tank is T3. In practical operation, if only the rainwater discharge condition of the M area is considered, namely the initial rainwater of the M area can enter the sewage treatment system through the storage tank, and the clean rainwater at the later stage can be discharged to the natural water body, T3 is required to be larger than T1, once T3 is exceeded, the storage tank immediately discharges to the natural water body, and the rainwater flowing to the storage tank in the N area is still the initial rainwater with serious pollution at the moment, namely T3 is smaller than T2, and the rainwater can certainly cause serious pollution when discharged to the natural water body.
If only the rainwater drainage condition of the N area is considered, namely T3 is larger than T2, the initial rainwater of the N area can enter the municipal sewage treatment system through the regulating storage tank and is well treated. However, for the M area, a large amount of later-stage clean rainwater in the M area is also discharged into the municipal sewage treatment plant within the time that the regulation and storage tank discharges the initial rainwater in the N area, and the discharge condition causes great treatment pressure on the municipal sewage system. In addition, when the system is in actual operation, pipe networks in the M area and the N area are generally in a communicated condition, and due to the difference of distances and the detention effect on the way, the initial rainwater in the N area can seriously pollute the clean rainwater in the later period of the M area, and the unreasonable rainwater discharge condition can be caused.
At present, a technical scheme for solving the above problems has been proposed in the prior art, that is, an urban pipe network system is subdivided according to unit areas by adopting a fragmentation treatment mode, but the existing pipe network system is usually suitable for a sunny state, and when rainwater falls temporarily, the maximum flow of a sewage main pipe is limited due to the limited treatment capacity of a sewage treatment plant in the pipe network; when heavy rain and heavy rain occur, water bodies in all unit areas cannot be discharged to a sewage treatment plant at the same time in time, and water logging disasters of different degrees in all unit areas are caused.
